Description

Medicine pumping and injecting device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a medicine pumping and injecting device.

Background

The injector is a common medical appliance, and consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for extracting a small amount of liquid and injecting the liquid into a required infusion bag or other places.

The current needle holding method of the injector is generally a three-pointer method. The specific operation is as follows: the forefinger and the middle finger are used for clamping the convex edge of the shell, and the thumb presses the push handle to control the push handle to move back and forth along the axial direction of the shell. When a syringe is used to aspirate a liquid, the medicine bottle is generally held by one hand and the syringe is operated by the other hand to aspirate the liquid. Therefore, when the syringe is used for sucking the liquid medicine, when the hands of some nurses are small or large-capacity liquid medicine is sucked, the force is not conveniently exerted by one hand, the liquid medicine is difficult to suck, or the medicine bottle is horizontally placed, the syringe is operated by two hands, but the medicine bottle is easy to topple over at the moment, so that the liquid medicine is spilled out to be wasted or to generate pollution.

Chinese patent "publication No. CN 208741665" discloses an injector one-hand withdrawal auxiliary device, which comprises a U-shaped fastener and a finger stall arranged at one side of the U-shaped fastener at intervals, wherein the finger stall is connected with the bottom of the U-shaped fastener, and at least one top end of the U-shaped fastener is provided with a bending part bent towards the direction of the finger stall. The U-shaped clamping piece is clamped outside the pintle and is propped against the lower part of the pressing handle, and the thumb of an operator can pass through the U-shaped clamping piece by a finger sleeve; when the syringe is used, the pressing handle is clamped between the U-shaped clamping piece and the finger sleeve, an operator penetrates the thumb into the finger sleeve, and the index finger and the middle finger are in abutting fit with the flange of the syringe, so that the syringe pintle is pushed and pulled; this scheme does not have auxiliary device when getting liquid, can not play the effect of economizing on labour, the reduction medical personnel's that can not burden. A device which can save time and labor when taking liquid by one hand is urgently needed.
