  • Patent number: 11260166
    Abstract: Disclosed are various embodiments for an anti-reflux tube-type enemator that is leakproof, easy-to-clean, and quickly inflates to provide a steady flow of solution. The anti-reflux enemator includes a nozzle comprising a nozzle outlet, a tube fluidly coupled to the nozzle, and an enema bulb fluidly coupled to the tube. The enema bulb is configured to store solution therein and, in response to a squeezing force applied to the enema bulb, direct the solution through the tube and the nozzle, and expel the solution through the nozzle outlet. An anti-reflux coupler is positioned between the enema bulb and the tube through which the solution passes from the enema bulb to the tube. One or more one-way air valves are positioned relative to an aperture of the enema bulb.

  • Publication number: 20140121645
    Abstract: The present invention provides an indirect method and accompanying apparatus for supplying a high concentration of medicaments, particularly antibiotics, to the nasal sinuses by first loading the medicament into the cerebrospinal venous system (CVCS) via a Valsalva maneuver. Because the CVCS is a valveless, three-dimensional closed system, traditional physiological dogma such as veins always draining tissues does not always apply. Instead, because in its closed-system blood can flow in any direction, the blood of the CVCS and any medicaments that it contains will be drawn to any portion of it where there is increased outflow, such as the copious venousderived sinus fluid drainage present during nasal allergy or nasal infection. Thus, the very nasal congestion that impedes the effectiveness of direct medicament application, such as seen with nasal inhalers or systemic antibiotics, aids in applying the medicament indirectly to the nasal sinuses via the CVCS.

The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by a nozzle at the distal ends of the first and second tube and a plurality of orifices or ports may be formed in the nozzle. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifice in a controlled and directed manner.

  • Patent number: 6428502
    Abstract: A lacrimal cannula, which is used for the removal of plugs or obstructions from mammalian lacrimal canaliculi having a punctum, includes a body having a distal portion, a proximal portion, an external annulus disposed proximate the distal portion, and a hollow bore for fluid delivery from the distal portion. The external annulus has an outer diameter greater than the outer diameter of the distal portion. The distal portion is inserted into the mammalian punctum without dilating the punctum and the external annulus has a generally spherical geometry which forms a seal with the external surface of the punctum without dilating the punctum and without the necessity of forcefully pressing the cannula against the punctal tissue to create a seal. The distal portion also has a relatively short length so that the distal portion is easily inserted into the canaliculus without contacting the plug or obstruction and thus interfering with the formation of the punctal seal.

  • Patent number: 6093176
    Abstract: A modular trocar assembly having a cannula, a passive valve seal assembly and an instrument seal assembly all releasably joined to define a central axial bore, where the passive valve seal assembly contains a valve seal which prevents passage of gas through the trocar assembly into the atmosphere when no instrument is inserted but which opens to allow for insertion of an instrument, and where the instrument seal assembly contains an instrument reducer seal which prevents passage of gas through the trocar assembly into the atmosphere when an instrument is inserted through the valve seal. The passive valve seal assembly and the instrument seal assembly are preferably composed of plastic so as to be disposable, while the cannula is preferably composed of a sterilizable material to enable reuse.

  • Patent number: 5599317
    Abstract: A sealable external access catheter including a portion implanted in the body of the patient, a fixation or anchoring sleeve extending through the skin, and a portion located outside the patient and provided as its free end with a self-sealing septum made of a material which is repeatably and sealably pierceable by an infusion instrument. The septum may include two fins forming a flat base enabling it to be easily attached to the patient's skin. The catheter is provided with a sealing plug whereby any danger of infection is avoided.

  • Patent number: 5584850
    Abstract: A trocar is adapted to form a seal around a surgical instrument and includes a cannula having an axis extending between a proximal end and a distal end. A seal housing disposed at the proximal end has a proximal wall with a hole extending into the housing. A septum valve disposed within the housing has a normal state when the instrument is absent from the trocar, and a stretched state when the instrument is being withdrawn from the trocar. A spacer extending between the proximal wall and the septum valve, engages the valve at a particular position which separates the valve into an inner portion, which is adapted to form a seal with the instrument and an outer portion, which is adapted to form a seal with the housing. The spacer has an axial length sufficient to space the particular position of the septum wall from the hole in the proximal wall a distance greater than the radial length of the inner portions of the valve in the stretched state.

  • Patent number: 5578017
    Abstract: A disposable flexible plastic enema nozzle with self-adhesive securing means for convenient attachment to the patient's buttocks is disclosed. The securing means comprises an annular positioning collar disposed about the enema tip or tube. The positioning collar has an elongated self-adhesive plastic sheet with easily removable protective tabs covering the adhesive. In one embodiment of the invention the positioning collar is fixed near the distal end of the tube, while in another embodiment the positioning collar is slidable along the tube for adjusting the insertion length of the tube. The invention is particularly applicable to diagnostic enema procedures, such as barium enema for radiological examination, performed on infants, small children, the infirm and the elderly.
