Description

Technical Field

[0001] This utility model relates to the field of medical accessory technology, specifically a reciprocating presser for a syringe. Background Technology

[0002] The process of using a syringe to draw in or inject gas or liquid is called injection. A syringe consists of a syringe barrel with a small hole at the front end and a matching piston rod. It is used to inject or extract small amounts of liquid into or from areas that are inaccessible by other means. When the piston rod is pulled out, the liquid or gas is drawn in through the small hole at the front end of the syringe barrel, and when the piston rod is pushed in, the liquid or gas is expelled.

[0003] Chinese utility model patent CN220237353U, published on December 26, 2023, discloses a handle structure for an automatic dissolving and dispensing machine. The structure includes a housing, a filter mounting plate mounted on the top surface of the housing, a filter mounting cylinder mounted through the filter mounting plate, a filter assembly inside the filter mounting cylinder, a needle tube sealed to the top of the filter mounting cylinder with a piston inside, and an insertion air tube sealed to the bottom of the filter mounting cylinder. An inflation tube is fixedly connected to the bottom of the insertion air tube and connected to an air source output device. An extension shell is fixed to the top surface of the housing, containing a needle tube mounting shell mounted on the top surface of the housing. A dispensing operation assembly is mounted on the extension shell. The housing consists of a first outer shell and a second outer shell, which are sealed and engaged from bottom to top. This utility model not only allows for efficient filtration during dispensing but is also simple to operate and easy to disassemble.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the reciprocating presser used in the existing drug dispensing technology uses a piston and positive and negative air pressure for driving connection. Although this method achieves a compact and lightweight structure, the precision of moving the piston rod to reciprocate is low, which makes it unsuitable when precise drug injection is required. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the reciprocating presser used in the existing drug dispensing technology uses a piston and positive and negative air pressure for driving connection. Although this method achieves a small and lightweight structure, the accuracy of moving the piston rod in reciprocating movement is low, which makes it unsuitable for precise drug injection. The invention provides a reciprocating presser for syringes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a reciprocating presser for a syringe, comprising an arm sleeve; a front extension plate is symmetrically fixed to one end of the arm sleeve; a fastener is threadedly connected to the front extension plate; a rear extension plate is sleeved on the fastener; a functional tube is fixedly connected between the rear extension plates; a free tube is rotatably connected to the functional tube through a slot; a limit ring is threadedly connected to the functional tube corresponding to the free tube; a gripping tube is inserted into the free tube through a hole; and a reciprocating pressing unit is provided on the gripping tube.

[0008] Furthermore, the reciprocating pressing unit includes an electric push rod fixedly connected to the grip tube with an opening; a connecting plate is fixedly connected to the movable rod of the electric push rod; a first locking groove is provided on the connecting plate; and a support tube is fixedly connected to the grip tube corresponding to the connecting plate.

[0009] Furthermore, a limiting groove is provided on the support tube; a second locking groove is provided in the limiting groove.

[0010] The reciprocating presser for a syringe provided by this utility model has the following beneficial effects:

[0011] 1. This utility model connects the hand to the arm sleeve by gripping the holding tube, thereby transferring the overall weight to the hand, wrist, and arm, reducing the labor intensity of the wrist. When multi-angle injection is required, the holding tube with the reciprocating pressing unit can rotate around the free tube or around the fastener, thus meeting the free angle use required for drug injection, saving manpower and improving efficiency. At the same time, under the precise displacement of the electric push rod, high-precision injection of the corresponding volume of liquid medicine is achieved.

[0012] 2. This utility model controls the reciprocating movement of the electric push rod, thereby causing the connecting plate and the piston rod of the syringe to move precisely back and forth, thus achieving precise aspiration and injection of medicine and saving manpower.

[0021] Please see Figure 1-3 As shown, a reciprocating press for a syringe includes an arm sleeve 1; a front extension plate 3 is symmetrically fixed to one end of the arm sleeve 1; a fastener 4 is threaded onto the front extension plate 3; a rear extension plate 5 is sleeved onto the fastener 4; a functional tube 6 is fixedly connected between the rear extension plates 5; a free tube 7 is rotatably connected to the functional tube 6 with a slot; a limit ring 8 is threaded onto the functional tube 6 corresponding to the free tube 7; a gripping tube 10 is inserted into the free tube 7 with a hole; and a reciprocating pressing unit is provided on the gripping tube 10. The grip tube 10 is connected by the palm passing through the arm sleeve 1 and holding it, thereby transferring the overall weight to the palm, wrist and arm, thus reducing the labor intensity of the wrist. When multi-angle injection is required, the grip tube 10, with the reciprocating pressing unit, can rotate around the free tube 7 or around the fastener 4, thereby meeting the free angle use required for drug injection, saving manpower and improving efficiency. At the same time, under the precise displacement of the electric push rod 11, high-precision injection of the corresponding volume of liquid medicine is achieved.

[0022] The reciprocating pressing unit includes an electric push rod 11 fixedly connected to the grip tube 10 with an opening; a connecting plate 12 is fixedly connected to the movable rod of the electric push rod 11; a first locking groove 13 is provided on the connecting plate 12; a support tube 16 is fixedly connected to the grip tube 10 corresponding to the connecting plate 12.

Thus, it can be precisely driven by the electric push rod 11 to inject precise liquid medicine, saving manpower and improving efficiency.

[0024] The limiting ring 8 has symmetrically provided insertion holes 9. Through the insertion holes 9, an external tool can be connected to rotate the limiting ring 8 on the functional tube 6 to fix it with threads, thereby restricting the displacement of the free tube 7.

[0025] The arm cannula 1, the forward extension plate 3, the rear extension plate 5, the functional tube 6, the free tube 7, the limiting ring 8, and the grip tube 10 are made of plastic, making the structure lightweight and transferring the overall weight from the wrist to the arm, thereby reducing the labor intensity of the wrist and reducing the labor wear and tear on medical staff.

[0026] The open end of the arm sleeve 1 is fitted with an elastic collar 2 made of rubber, which increases the friction with the arm or sleeve, so that it will not wobble more when the arm moves.
