The device is particularly intended for use where suction such as nipples, straws, or sip cups are contraindicated after craniofacial surgery.
This is a divisional of pending U.S. patent application Ser. No. 10/309,687, filed on Dec. 4, 2002.
This invention was described in provisional U.S. patent application Ser. No. 60/338,475, which was filed in the U.S. Patent & Trademark Office on Dec. 4, 2001.
BACKGROUND OF THE INVENTION1. Technical Field
The present device relates generally to a squeezable, collapsible, disposable and/or reusable bottle device with flexible tubing for dispensing liquid nutrition or the like to post-surgical maxillo, craniofacial, and other reconstruction patients.
2. Background Information
Physicians prohibit infants and children who have had surgery for a cleft lip or cleft palate from breast feeding or sucking on a nipple or straw, so it is difficult to feed them. Suction on any feeding device is contraindicated after such reconstructive surgery. Currently, such infants are fed using a piece of tubing inserted over the open end of a syringe. A syringe with tubing is used so as not to disrupt, traumatize, or break open swollen, sutured tissue in the palate and/or lip. Suction, as occurs on a nipple, is contraindicated because it can cause bleeding, hematomas, dislodged sutures, and otherwise impair healing. The tube extending from the syringe must be inserted along the left or right side of the infant's mouth so as not to disturb the sutures and wound site.
There are many problems with syringe feeding. First, a filled syringe is very difficult to manipulate. It takes both hands to fill the syringe and dispense the viscous formula through it. It is difficult to control pressure on the syringe plunger so that the correct amount of fluid is dispensed into the child's mouth. Dispensing too much fluid too fast can cause the child to gag or spit up. Holding the baby and depressing the syringe at the same time is awkward.
Second, syringes generally hold only a limited amount of formula and must be repeatedly refilled during a single feeding. These infants are fussy and often in pain from the surgery and they are disturbed by the repeated halts in their feeding. Refilling the syringe is messy and inconvenient, especially in a hospital room or nursery.
Third, the baby moves around during feeding and the tubing sometimes comes loose from the syringe. Then the loose tube is a hazard in the baby's mouth, and the baby's wet shirt must be changed.
Fourth, feeding becomes more of an uncomfortable medical procedure when it is done with a syringe. Many hospitalized children associate a syringe with painful shots and become belligerent when they see a syringe. Syringe feeding can be intimidating for both the parent and the child. The child must be fed several times per day, and the disadvantages of this type of feeding make feeding time a chore for both the baby and the stressed mother or other caregiver. The baby expends a great deal of energy resisting feeding, and the mother or other caregiver is worn out. Feeding time should instead be a soothing experience for these babies and their mothers.
The same types of problems are encountered in feeding other post-surgical patients who have had maxillo or craniofacial surgery, or who are simply infirm or unable to feed normally due to medical problems of the face or mouth. The problems are further aggravated in that some of these babies and children must undergo repeated reconstruction as they grow. For example, children with a cleft palate often have to return to the hospital for surgery several times between the ages of three weeks and about two years.
BRIEF SUMMARY OF THE INVENTIONThe present invention is a squeezable, disposable or refillable device with a flexible tubing for feeding liquids to a patient who has had maxillo, craniofacial, or related types of reconstruction surgery, or has other facial impairments. The feeding device includes:
-
- a) a bottle portion for containing the ingestible fluid, the bottle portion comprising an opening at its top surrounded by a neck having exterior threads; and
- b) a cap assembly comprising: flexible, fluid-flow tubing, a spout or nipple assembly, and a threaded collar, the tubing extending through or encircling a central aperture in the spout or nipple assembly, an upper portion of the spout or nipple assembly being insertable through a central aperture in the collar, the collar having interior threading engageable with the correspondingly threaded neck of the bottle portion, the collar extending down over the neck; wherein the tubing is insertable into the mouth of the patient.
The present invention also includes a bottle device for feeding liquid nutrition to a patient or for teaching a patient to suck, comprising:
-
- a) a squeezable bottle portion for holding the ingestible fluid therewithin, the bottle portion comprising an open top surrounded by a neck; and
- b) a leakproof cap assembly comprising: a spout assembly, a collar, and fluid conducting tubing, the collar comprising corresponding interior threads for removably interengaging the neck of the bottle portion; the spout assembly comprising a peg on its upper portion and a flange on its lower portion, the peg extending in an upward direction through a central aperture in the collar, the fluid-conducting tubing having a first, upper end that is insertable into a mouth of the patient and a second, lower end that is removably attachable over the peg, the flange extending closely into the open top of the bottle portion for preventing leaks, a portion of the spout assembly being mounted on the neck of the bottle portion, the spout assembly comprising a central channel for conducting fluid from the bottle portion to the tubing.
Advantages of the present invention for a baby or older patient include the following:
-
- a) the squeezable bottle and flexible tubing allow passive administration of fluids while preventing suction by the patient and injury to the surgical site;
- b) the tubing portion of the present invention can easily be inserted in the side of the patient's mouth without being dislodged;
- c) the feeding device does not physically disrupt the sutures or swollen tissue in the jaw, palate or lip, and is very unlikely to cause trauma to the surgery site;
- d) the bottle portion of the present invention holds enough for a full feeding;
- e) the bottle portion is squeezable for administering the fluid in the bottle, so the mother can hold the baby and feed him or her at the same time, and fluid volume can be easily controlled;
- f) the baby can also grasp the bottle portion without adverse consequences;
- g) the baby and caregiver are more comfortable during feeding times, and feeding is effortless and more enjoyable for both;
- h) the present invention is more natural looking and less surgical in appearance, which is important to both parent and child;
- i) the present invention is inexpensive and refillable or disposable;
- j) formula, pureed food, and other types of fluids are passively and effortlessly dispensed to the patient;
- k) the present feeding device simplifies the ingestion of liquid nutrition, so the patient consumes more nutrients, and there are fewer postoperative complications, such as weight loss and dehydration; and
- l) the present invention is versatile and can be used by patients of any age. With the present feeding device, feeding times can be close to normal, even though the abnormal (hospital) environment remains.

Various parts of a preferred embodiment of the feeding bottle device 10 are shown in
Continuing with
The cap assembly 12 of the preferred embodiment illustrated in
In this preferred embodiment, the separate tubing is advantageous because it can be replaced after use. Alternatively, the entire bottle device 10 may be disposable, or it can be cleaned and refilled for more feedings with the same patient. The bottle portion typically holds about four to ten, preferably eight, ounces of liquid. It is preferably includes calibration lines so that the caregiver can assess how much of the fluid the infant, or patient, has consumed.
The collar 22 and spout 16 may be made of molded silicone, synthetic or natural rubber, or other suitable material. Alternatively, the spout 16 may be comprised of several pieces that are affixed to one another. The tubing is made of a conventional soft, flexible tubing material. The body of the bottle portion is made of a soft, collapsible plastic, such as a polyethylene.
The present invention is also useful for feeding geriatric patients who have had strokes, periodontal patients, patients with oral, or pharyngeal cancers, or general weakness at the front of the mouth, etc. These patients may be in hospitals, clinics, extended care facilities, or under home care.
