Description

Technical Field

[0001] The utility model belongs to the field of medical devices, in particular to a paclitaxel dispensing aid for injection. Background Art

[0002] Paclitaxel (albumin-bound) for injection is a sterile, lyophilized block or powder before dispersing and dissolving. During preparation, sodium chloride injection must be added before dispersing and dissolving. During preparation, bubbles must be avoided, so vigorous shaking is not recommended. If bubbles occur, the bottle must be left standing for at least 15 minutes to dissipate. Because albumin-bound paclitaxel generally has poor solubility, dispensing often requires the dispenser to gently shake the bottle or slowly invert it for at least two minutes to allow the internal components to fully dissolve. However, dissolution often fails during actual preparation. Due to the large dosage of paclitaxel (albumin-bound) for injection in recent years, preparation requires a large volume, and manual handling typically only allows for two bottles at a time, making preparation time-consuming and labor-intensive, requiring improvement. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a paclitaxel preparation auxiliary device for injection.

[0004] The utility model adopts the following technical solutions:

[0005] A paclitaxel dispensing aid for injection comprises a base, a placement seat and a clamping mechanism, wherein the base is provided with a swing shaft whose axis extends in the horizontal direction; the placement seat is rotatably arranged on the swing shaft and is used to place a paclitaxel medicine bottle; a plurality of clamping mechanisms are provided, which are arranged on a placement groove and are used to clamp the paclitaxel medicine bottle, and comprise clamping jaws, a rotating shaft, a shaft sleeve and a counterweight block, wherein the clamping jaws are arranged relative to each other and can be fitted to the bottom and side surfaces of the paclitaxel medicine bottle; the rotating shaft is arranged on the placement seat; the shaft sleeve is arranged at the outer bottom of the clamping jaw and can cooperate with the rotating shaft; the counterweight block is arranged at the outer top of the clamping jaw and can cause the clamping jaw to rotate outward around the rotating shaft to open the clamping jaw, and after the bottom of the paclitaxel medicine bottle contacts the clamping jaw, the clamping jaw rotates inward under the action of gravity to close the clamping jaw and clamp the paclitaxel medicine bottle.

[0006] Preferably, the clamp includes a vertical section, a bottom section and a neck section. There are two vertical sections, which extend in the vertical direction and can be attached to the side of the medicine bottle; the bottom section is vertically connected between the bottoms of the two vertical sections, and the top surface of the bottom section can contact the bottom of the medicine bottle; the neck section is vertically connected between the tops of the two vertical sections, and the neck section can cooperate with the neck of the medicine bottle as the clamp closes.

DETAILED DESCRIPTION

[0023] The present invention is further described below through specific implementation methods.

[0024] like Figures 1 to 6 As shown, a paclitaxel dispensing aid for injection includes a base 1, a placement seat 2, a clamping mechanism 3, and an up and down oscillation mechanism 4.

[0025] The base 1 includes a base plate 11, a side plate 12 vertically arranged on one side of the base plate 11, a sliding groove 13 extending downward from the top surface of the side plate 12, a lifting rod 14 that can be lifted and lowered in the sliding groove 13, and a swing shaft 15 arranged on the lifting rod 14 and with its axis extending in the horizontal direction.

[0026] A susceptor 2 is rotatably mounted on a swing shaft 15 and is used to hold a paclitaxel vial. The vial to be dissolved is placed in susceptor 2, which is then pushed to one side and released. Susceptor 2 swings under its own weight, automatically shaking the vial. Dispensers only need to keep susceptor 2 swinging, significantly improving dispensing efficiency and reducing their workload.

[0027] The clamping mechanism 3 is provided with several parts and is arranged on the placement slot for clamping the paclitaxel bottle. The clamping mechanism 3 includes a clamping jaw 31, a rotating shaft 32, a sleeve 33, and a counterweight 34. The clamping jaws 31 are arranged relative to each other and can be attached to the bottom and side surfaces of the paclitaxel bottle. The rotating shaft 32 is arranged on the placement seat 2. The sleeve 33 is arranged at the bottom outside the clamping jaw 31 and can cooperate with the rotating shaft 32. The counterweight 34 is arranged at the top outside the clamping jaw 31 and can rotate the clamping jaw 31 outward about the rotating shaft 32 to open the clamping jaw 31. After the bottom of the paclitaxel bottle contacts the clamping jaw 31, the clamping jaw 31 rotates inward under the action of gravity to close the clamping jaw 31 and clamp the paclitaxel bottle. The counterweight 34 offsets the center of gravity of the clamping jaw 31, so that the clamping jaw 31 can be opened by its own gravity when idle, eliminating the need for manual separation of the clamping jaw 31, thus improving practicality. The weight of the medicine bottle drives the clamping jaws 31 to close inward, automatically clamping the medicine bottle, which can effectively prevent the medicine bottle from tipping over or overturning. When taking the medicine bottle, you only need to lift the medicine bottle upwards, and the clamping jaws 31 will automatically release the medicine bottle, making it extremely convenient to take and place the medicine bottle.

[0028] The top of the fixing plate 312 is provided with a fixing piece 314 and a fixing piece 315, and the fixing piece 314 is fixed to the fixing plate 312 by the fixing piece 316. Due to the special structure of the clamp 31, when closed, the vertical section 311, the bottom section 312 and the neck section 313 are in contact with the side, bottom and neck of the medicine bottle respectively. The clamp 31 can completely fit the medicine bottle, further improving the clamping stability of the clamp 31.

[0029] Furthermore, a limiting plate 21 is provided on the placement seat 2. The limiting plate 21 is provided on the placement seat 2 and its height is higher than the height of the rotating shaft 32. A plurality of limiting holes 22 corresponding to the clamping mechanism 3 are formed on the limiting plate 21. The clamping claw 31 can be supported on the side of the limiting hole 22 after rotating outward.

[0030] The up-and-down oscillation mechanism 4 is disposed on the base 1 and connected to the lifting rod 14. The up-and-down oscillation mechanism 4 includes a clearance groove 41, a cam 42, and a driving handle 43. The clearance groove 41 is formed in the side panel 12 and located below the sliding groove 13. The top surface of the clearance groove 41 is connected to the bottom surface of the sliding groove 13. The cam 42 is rotatably disposed in the clearance groove 41 about an axis perpendicular to the side panel 12. The bottom surface of the lifting rod 14 contacts the cam 42 and moves up and down as the cam 42 rotates. The driving handle 43 is disposed on the side panel 12 and connected to the cam 42 to drive the cam 42 to rotate. The cam 42 drives the lifting rod 14 up and down, assisting the placement seat 2 in moving up and down to complete the oscillation of the medicine bottle. This device can perform multi-directional bottle oscillation and improve the dissolution efficiency of the medicine in the medicine bottle. Specifically, limit rods 16 are also disposed on both sides of the side panel 12 to limit the rotation range of the placement seat 2. This can limit the rotation range of the placement seat 2 and prevent the medicine bottle from tipping over and falling from the placement seat 2 due to excessive rotation.

[0031] During use, the paclitaxel medicine bottle is placed in the limiting hole 22 from top to bottom and falls into the clamping claw 31. Since the clamping claw 31 will open outwards due to its own center of gravity when it is stationary, the bottom surface of the clamping claw 31 is tilted upward. Since the bottom surface of the medicine bottle contacts the bottom section 312 of the clamping claw 31, the bottom section 312 flips downward under the gravity of the medicine bottle, driving the clamping claw 31 to move closer to the center and clamp the medicine bottle. Then the training staff pushes the placement seat 2 to one side until it contacts the limiting rod 16 and releases the placement seat 2. The placement seat 2 performs reciprocating swinging motion under its own gravity (placing the medicine bottle so that the number of left and right medicine bottles on the placement seat 2 is consistent to maintain the weight balance on both sides of the placement seat 2 to avoid affecting the swing). The dispensing staff only needs to intermittently push the placement seat 2 to continue swinging until the substance in the medicine bottle is completely dissolved. After it stops swinging, the medicine bottle can be taken from bottom to top for use. This application greatly improves the efficiency of dispensing, reduces the workload of the dispensing staff, and is convenient and quick to place and take medicine bottles, with great practicality.

[0032] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
