Description

Technical Field

[0001] This utility model relates to the field of medical device processing technology, specifically a device for testing the sliding performance of a double-tube syringe. Background Technology

[0002] The invention of the syringe was a revolutionary breakthrough in the field of medical devices. The process of drawing or injecting gas or liquid with a needle is called injection. A syringe consists of a syringe barrel with a small hole at the front end and a matching plunger. It is used to inject or extract small amounts of liquid into areas inaccessible by other methods. When the plunger 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 plunger is pushed in, the liquid or gas is expelled.

[0003] After the syringe is manufactured, the sliding performance of the plunger needs to be tested. However, current testing equipment can only test single-tube syringes; it cannot effectively test the sliding performance of double-tube syringes.

[0004] In view of the above-mentioned prior art, it is desirable to provide a device for testing the sliding performance of a dual-tube syringe. Utility Model Content

[0008] The first vertical plate is vertically fixed to the base;

[0009] The socket is fixed to the top of the first vertical plate, and the outer side of the socket is provided with two socket parts for connecting a double-tube syringe.

[0010] The drive mechanism includes a support frame, a motor, a lead screw, a slider, and a pusher component;

[0011] The lead screw is vertically rotatably mounted on the support frame;

[0012] The motor is used to drive the lead screw to rotate;

[0013] The slider is threadedly fitted onto the lead screw;

[0014] The pusher component includes a support base and a pusher rod;

[0015] The support base is fixed to the outside of the slider;

[0016] The push rod is fixed vertically downward on the support base, and a push block is fixed at the bottom of the push rod.

[0017] Preferably, a horizontal plate is provided on the socket directly above each socket part, and a bolt is threaded on the horizontal plate, the bolt passing through the horizontal plate.

[0018] Preferably, a second vertical plate is vertically provided on the support base.

[0019] Preferably, a limiting plate is vertically provided on the base, and the limiting plate is located directly below the support.

[0020] Furthermore, the top of the limiting plate is provided with an elastic rubber block.

[0025] Figure 2 for Figure 1 Enlarged view of a portion of point A in the middle;

[0026] Figure 3 This is a schematic diagram of the operation of a dual-tube syringe sliding performance testing device in this embodiment. Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1 As shown, a dual-tube syringe sliding performance testing device includes a fixing mechanism and a driving mechanism.

[0030] The fixing mechanism includes a base 1, a first vertical plate 2, and a socket 3; the first vertical plate 2 is vertically fixed on the base 1; the socket 3 is fixed on the top of the first vertical plate 2, and the outer side of the socket 3 is provided with two socketing parts 4 for connecting a double-tube syringe.

[0031] In this embodiment, as Figure 2As shown, a horizontal plate 5 is provided on the socket 3 directly above each socket part 4. A bolt 6 is threaded on the horizontal plate 5 and passes through the horizontal plate 5. With this arrangement, after the double-tube syringe is sleeved on the socket part, the bolt 6 can be tightened to fix the double-tube syringe and prevent it from falling off.

[0032] The driving mechanism includes a support frame 7, a motor 8, a lead screw 9, a slider 10, and a pusher component; the lead screw 9 is vertically rotatably mounted on the support frame 7; the motor 8 drives the lead screw 9 to rotate; the slider 10 is threaded onto the lead screw 9; the pusher component includes a support base 11 and a pusher rod 12; the support base 11 is fixed to the outside of the slider 10; the pusher rod 12 is vertically fixed downward on the support base 11, and a pusher block 13 is fixed to the bottom of the pusher rod 12.

[0033] like Figure 3 As shown, when testing the sliding performance of the dual-tube syringe, the motor 8 drives the lead screw 9 to rotate, so that the slider 10 moves linearly on the lead screw 9, and finally the pusher moves in the vertical direction. The pusher block 13 pushes the two push rods on the dual-tube syringe, effectively testing the sliding performance of the syringe.

[0034] In this embodiment, a second vertical plate 14 is vertically provided on the support base 11; with this arrangement, the second vertical plate 14 plays a role in bearing the weight, further ensuring that the pusher will not shake when it moves in the vertical direction.

[0035] In this embodiment, a limiting plate 15 is vertically provided on the base 1, and the limiting plate 15 is located directly below the support base 11; this arrangement effectively limits the pusher and prevents the push rod in the double-tube syringe from damaging the syringe shell.

[0036] Furthermore, the top of the limiting plate 15 is provided with an elastic rubber block 16, which plays a certain role in cushioning.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
