Publication number: 20240024580Abstract: A reloadable medicine injector and methods are described in which a barrel with a receiving cavity is adapted to slidably receive a syringe subassembly for axial movement therein. Upon removal of a safety and release of a syringe driver, the syringe driver moves forward and injects the syringe needle. A plurality of penetration controls are shown for controlling injection needle penetration depth. The penetration controls have an abutment and various lengths to provide different needle penetration depth positions. In one form of penetration control a sleeve is used against which the syringe or related parts contact. In another form the front return spring is used as a penetration control. A cushioning ring may be used to reduce syringe breakage. A load distribution and guide ring may be used to distribute loading applied to the syringe and help guide the moving syringe.Type: ApplicationFiled: August 7, 2023Publication date: January 25, 2024Applicant: Washington Biotech CorporationInventor: Ronald E.

Patent number: 9265886Abstract: Medicine injection apparatuses having multiple chambers. The chambers may be in lateral relationship. A torsional part is adapted to turn and be repositioned angularly relative to a main body to allow different chambers to be used to receive an injection assembly. The medicine injector can be constructed to administer multiple doses. The apparatuses may also have a storage chamber for storing the injection assembly after use. Plural drivers may be used to administer multiple doses, such as at the different angular positions of the torsional part. The apparatuses may allow multiple automatic injections from different angular positions and storage of an injector after use. Needle fright is reduced by minimizing exposure of an injection needle prior to injection.Type: GrantFiled: February 1, 2013Date of Patent: February 23, 2016Assignee: Washington Biotech CorporationInventor: Ronald E.

Patent number: 8187224Abstract: Operations performed by a medicine injector having a barrel with a receiving cavity to slidably receive a syringe subassembly for axial movement therein. Upon removal of a safety and release of a syringe driver, the syringe driver moves forward and injects the syringe needle. One or more penetration controls are shown for controlling injection needle penetration depth. In some forms of penetration control a sleeve and spring are used in the methods performed. This construction and a cushioning piece or pieces may be used to reduce the forces experienced by the syringe subassembly. A load distribution ring may further be used with a cushion, spring and guide ring which may be used to help distribute deceleration loading experienced by the syringe subassembly.Type: GrantFiled: September 29, 2009Date of Patent: May 29, 2012Assignee: Washington Biotech CorporationInventor: Ronald E.
