DETAILED DESCRIPTION

[0023] The present application will be described in detail below with reference to the exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concepts of the present application to those skilled in the art.

Therefore, it should not be understood as limiting the scope of protection of this application.

[0025] The problem in the prior art is that the medical staff have to use a lot of force to cut the infusion pump multiple times, which is not friendly to the hand muscles. After careful analysis, the inventors found that the main reason for the above problems is that the current conventional way to cut the infusion pump is to rely on the medical staff to cut it with scissors by their shearing force. However, the use of scissors requires the coordination of the fingers and palms, such as the thenar muscles, to contract the scissors to close them. The infusion pump includes a needle and an infusion tube. Whether cutting the needle or the infusion tube, a lot of force is needed to control the scissors to close. When cutting multiple times, the muscles of the palm are frequently in a state of relaxation and contraction, which is prone to fatigue. Over time, the muscles are exhausted. When the palm is tired, it takes more force to pinch the scissors, which increases the shearing strength. This reciprocating process may cause muscle strain on the palm. Based on the above analysis, the inventors have made structural improvements to the tools for cutting infusion tubes.

[0026] like Figure 1 As shown, in one embodiment of the infusion set cutting auxiliary device of the present application, the device includes:

[0027] The metal housing 1 has an open top and is fitted with a metal top cover 2 by screws 23. The top surface of the top cover 2 is provided with a placement opening 2-1. The right end of the housing 1 is provided with an axial hole, and the bottom is provided with a waste outlet for the infusion set with the cut end dropped out.

[0028] The cutting part includes a first blade 14 and a movable blade assembly. The first blade 14 is arranged on the left side of the interior of the shell 1. Specifically, two long rectangular clips 19 are welded equidistantly on the left side wall of the interior of the shell 1. The first blade 14 is placed between the two clips 19. The top surfaces of the clips 19 and the first blade 14 are provided with coaxial through holes. Bolts are provided in the through holes. The first blade 14 is fixed to the two clips 19 by tightening the bolts and nuts. The detachable manner facilitates the replacement of the first blade 14. The movable blade assembly includes two guide rails equidistantly welded on the right side of the interior of the shell 1 and facing the left side. Rod 11, a slider 9 that can move along the guide rod 11 is sleeved on the two guide rods 11, and a second blade 13 is provided at the middle of the left end of the slider 9. Specifically, two long rectangular clips 19 equidistantly distributed above and below are welded to the left end of the slider 9. The second blade 13 is placed between the two clips 19 there. A coaxial through hole is opened on the top surface of the clip 19 and the second blade 13. A bolt is provided in the through hole. The second blade 13 is fixed to the two clips 19 there by tightening the bolt and nut. The detachable manner facilitates the replacement of the second blade 13; a spring 10 is sleeved on the left end of the slider 9 and the guide rod 11;

[0029] And a pushing assembly, which includes a rotating disk 8, the rotating disk 8 is located on the right side of the slider 9, the left end of the rotating disk 8 is provided with a pushing block 4 with a gradient thickness, and the right end is welded with a rotating shaft 22, which is provided in the shaft hole of the housing 1, wherein Figure 4 As shown, a shaft sleeve 20 is welded to the shaft hole, and the shaft sleeve 20 and the rotating shaft 22 increase the contact area to prevent the rotating shaft 22 from tilting. A handle 6 is installed at the end of the rotating shaft 22 away from the housing 1.

[0030] Since the infusion pump is relatively long, after the infusion tube is placed into the placement port 2-1 of the top cover 2, the infusion tube may deviate to one side, making it impossible to cut. Therefore, a rectangular guide tube body 3 facing the inside of the shell 1 is welded in the placement port 2-1. The opening of the guide tube body 3 is located above between the first blade 14 and the second blade 13. The sizes of the placement port 2-1 and the guide tube body 3 depend on the infusion pump. With the restriction of the guide tube body 3, the swing amplitude of the infusion pump is reduced, so that the infusion pump can fall between the first blade 14 and the second blade 13, and cutting is smoothly achieved.

[0031] The function of the spring 10 is to push the slider 9 back to its original position through elastic force when the slider 9 moves to the right and is not squeezed by the push block 4. Therefore, a limit block 12 is provided at the left end of the spring 10. The limit block 12 is sleeved on the guide rod 11. In order to facilitate the replacement of the spring 10, the limit block 12 adopts a nut, and the side wall of the left end of the guide rod 11 is provided with a thread, and the nut and the thread are connected.

[0032] The top surface of the slider 9 is preferably an arc surface, such as Figure 5 As shown, the push block 4 is arc-shaped, with its proximal end being the starting end 4-1 and the distal end being the ending end 4-2. The left end surface of the push block 4 thickens from the starting end 4-1 to the ending end 4-2, ultimately forming a push block 4 with a gradually varying thickness. The left end surface of the push block 4 contacts the arc-shaped surface of the slider 9. Figure 2 and Figure 3 As shown, the pushing block 4 is located above the slider 9. When the handle 6 is swung forward, the pushing block 4 is driven to rotate by the rotating disk 8, and the starting end 4-1 of the pushing block 4 rotates and moves downward. The left end face of the pushing block 4 gradually contacts the arc surface of the slider 9. The more the handle 6 is swung forward, the closer the terminal end 4-2 of the pushing block 4 is to the slider 9. The thickness of the terminal end 4-2 is thicker than the starting end 4-1, so that the slider 9 is squeezed to the left by the pushing block 4, and the slider 9 drives the second blade 13 to move toward the first blade 14 to achieve closed cutting.

[0033] Combine Figure 4 and Figure 5 As shown, a square limiting sleeve boss 22-1 is provided on the outside of the rotating shaft 22 located outside the housing 1, and the rotating shaft 22 extends a short distance to the right end of the sleeve boss 22-1; a socket 6-1 corresponding to the sleeve boss 22-1 is provided at one end of the handle 6. When in use, Figure 2 and Figure 3 As shown, the socket 6-1 of the handle 6 is sleeved onto the sleeve boss 22-1. The sleeve boss 22-1 and the socket 6-1 cooperate to drive the rotation shaft 22, the rotating disk 8, and the push block 4 to rotate. When not in use, the handle 6 can be withdrawn to the right and placed on the shaft 22 at the right end of the sleeve boss 22-1, so that the handle 6 does not need to be upright for a long time and interfere with other operations of the medical staff. To prevent the handle 6 from falling out of the shaft 22, a threaded hole is opened at the right end of the shaft 22. A gasket 21 with a diameter larger than the shaft 22 is set at the right end of the shaft 22 and is fixed by a screw 23.

[0034] In order to prevent the handle 6 from being pressed down too much, causing the terminal end 4-2 of the push block 4 to move to the bottom of the slider 9, resulting in the push block 4 being unable to reset, a second limit rod 7 is welded to the right end of the shell 1 and the front side of the sleeve 20. When the handle 6 touches the second limit rod 7, it cannot swing excessively. At the same time, this position is also the position where the cutting is completed. In addition, the second limit rod 7 can also be made to swing downward when the handle 6 is not in use, making it easier for medical staff to take the handle 6. At the right end of the shell 1, above and behind the sleeve 20, a first limit rod 5 is also connected. When the handle 6 touches the first limit rod 5, it indicates that the left end face of the push block 4 is not in contact with the slider 9, that is, the slider 9 is in the initial position. The first limit rod 5 and the second limit rod 7 can both serve as a reminder when the field of vision cannot pass through the shell 1.

[0035] A waste outlet is provided at the bottom of the shell 1 through which the cut end of the infusion set falls out. The waste outlet is connected to a waste chamber 16. The top of the waste chamber 16 is communicated with the waste outlet. An outlet is provided on the left end face of the waste chamber 16. A push plate 17 is provided inside the waste chamber 16. A push rod 18 is connected to the right end of the push plate 17. A through hole for the push rod 18 to pass through is provided at the right end of the waste chamber 16. The push plate 17 is controlled by the push rod 18 to move. When the waste material of the cut infusion set falls into the waste chamber 16, it is pushed into the medical device recycling bin by the push plate 17.

[0036] Taking into account the residual liquid in the cut infusion set, a through hole is opened at the bottom of the waste chamber 16. The bottom of the waste chamber 16 is symmetrically provided with an L-shaped clip 16-1, which can clamp the flange of some containers containing liquid. When the cut infusion set falls into the waste chamber 16, the liquid inside it flows into the container containing liquid through the through hole.

[0037] In addition, a fixing buckle 15 is welded to the left end of the housing 1. The fixing buckle 15 is made of angle iron and has a bolt connected to its left end. The device can be fastened to the side of the treatment cart via the fixing buckle 15 and tightened with the bolt. The device has a compact structure and can be placed on the side of the treatment cart without taking up too much space.

[0038] When using the device, first fix it to the side of the treatment cart through the fixing buckle 15, then remove the handle 6 from the Figure 1 The handle 6 is in a vertical state, and the effect is referenced to Figure 2 ; Insert one end of the infusion set into the guide tube body 3 through the placement opening 2-1 of the top cover 2, so that the infusion set falls between the first blade 14 and the second blade 13, hold one end of the handle 6, press down to the front end, and the handle 6 drives the rotating shaft 22, the rotating disk 8 and the pushing block 4 to rotate. As mentioned above, the pushing block 4 will squeeze and push the slider 9 to move to the left, so that the second blade 13 moves to the left, and finally closes with the first blade 14 to form a cutting action, cutting off the infusion set. The effect is reference Figure 3 After resetting the handle 6, the slider 9 is not blocked by the push block 4, driving the second blade 13 to reset to the right, and then the above operation can be repeated to continue cutting the infusion set.

[0039] The cut infusion waste falls into the waste chamber 16. After cutting, push the push rod 18 to the left, and the push rod 18 drives the push plate 17 to push the waste in the waste chamber 16 into the waste medical device recycling bin under the treatment cart. Finally, withdraw the handle 6 from the sleeve boss 22-1 and put it into Figure 1 Status is enough.

[0040] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of this application should be within the scope of protection of this application.
