Description

Technical Field

[0001] The utility model relates to the technical field of surgical nursing, in particular to a surgical drainage tube with an anti-bending mechanism. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage, which guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body, prevents postoperative infection, and promotes wound healing. For example, a drainage tube for chest surgery with a publication number of "CN213220414U" is an anti-blocking drainage tube. The drainage tube is fixed by a strip-shaped air bag in contact with human tissue, which can stretch the human tissue in the chest cavity, so that there is a gap between the outer wall of the drainage tube and the human tissue, and because the through hole is in the arc groove, it can avoid blockage caused by contact between the human tissue and the through hole; a plurality of circular air bags can be inflated through the air supply pipe 2, and as the circular air bags expand, they drive the expansion plate to move outward, which can expand the inner wall of the drainage tube, so that the dirt in the drainage material can be smoothly discharged from the drainage tube, avoiding blockage of the drainage tube. However, the drainage tube still has the following disadvantages in actual use:

[0003] When the above mechanism is in use, since the drainage tube is mostly made of medical silicone, the drainage tube is relatively soft, which causes the drainage tube located near the patient's end to bend easily when the patient turns over or moves, thereby slowing down the transportation of liquid in the drainage tube and affecting treatment.

[0004] Therefore, we have proposed a surgical drainage tube with an anti-bending mechanism that can well solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a surgical drainage tube with an anti-bending mechanism to solve the problem raised in the above-mentioned background technology that since most drainage tubes are made of medical silicone, the drainage tubes are relatively soft, which leads to the drainage tube located near one end of the patient being easily bent when the patient turns over or moves, thereby slowing down the transportation of liquid in the drainage tube and affecting the treatment.

[0012] Preferably, a cutting piece is installed inside the connecting pipe, and sealing gaskets are embedded on the opposite surfaces of the first docking ring and the second docking ring. The sealing gaskets can improve the sealing performance between the drainage pipe body and the connecting pipe.

[0013] Preferably, a plurality of clamping blocks are equiangularly fixed on one side of the first docking ring, and grooves are formed on the side surfaces of the clamping blocks. A plurality of clamping grooves are equiangularly formed on the side of the second docking ring away from the connecting pipe, and a limiting block is slidably connected to the upper end of the clamping groove inside the second docking ring. A return spring is installed between the outer side of the limiting block and the inner wall of the second docking ring.

[0014] Preferably, the positions of the clamping blocks and the clamping grooves correspond one by one, and the clamping blocks and the clamping grooves are in clamping connection.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 7 , the present utility model provides the following technical solution: a surgical drainage tube with an anti-bending mechanism

[0032] Embodiment 1: To solve the problem in the prior art that since most drainage tubes are made of medical silicone, the drainage tubes are relatively soft, resulting in the position of the drainage tube near the patient being prone to bending when the patient turns over or moves, thereby causing the liquid in the drainage tube to be transported slowly and affecting the treatment. Therefore, the following solution is disclosed. Specifically, refer to Figures 1 - 4 As shown, it includes a drainage tube body 1. A fixing block 2 is sleeved and fixed on the outer side of the left end of the drainage tube body 1, and a connecting tube 3 is arranged inside the drainage tube body 1;

[0033] It further includes: a worm 7 is connected by a bearing at the front end inside the fixing block 2, and a worm ring 8 is rotatably connected at the rear end inside the fixing block 2. The right end of the worm 7 penetrates through the inside of the fixing block 2, and the worm 7 is in meshing connection with the worm ring 8. Tooth blocks 9 are installed at equal angles on the inner side of the worm ring 8. Shaft rods 12 are rotatably connected at equal angles inside the fixing block 2 on the inner side of the worm ring 8, and driven gears 10 and movable plates 11 are respectively sleeved and fixed on the outer sides of the shaft rods 12. The inner side of the worm ring 8 is arranged in a serrated shape, and the tooth blocks 9 are in meshing connection with a plurality of driven gears 10. The plurality of movable plates 11 are arranged in an arc shape; both ends of the connecting tube 3 are fixedly connected with second docking rings 5, and first docking rings 4 are fixedly connected at both ends of the connecting tube 3 inside the drainage tube body 1;

[0034] During use, medical staff pass the drainage tube body 1 through the fixing block 2, insert one end into the patient's body, connect the other end to the drainage bag, and at the same time fix the fixing block 2 on the patient's body with medical tape. Then, the medical staff manually rotate the worm 7 forward to drive the worm ring 8 to rotate. At the same time, the tooth blocks 9 on the inner side of the worm ring 8 rotate to drive six driven gears 10 to rotate, and then the movable plates 11 rotate to clamp and fix the outer side of the drainage tube body 1, thereby preventing the end of the drainage tube body 1 close to the patient's body from bending and falling off, ensuring the smoothness of the drainage tube body 1. After that, when the drainage is over, the medical staff rotate the worm 7 in the reverse direction to drive the worm ring 8 to reverse, and then the six driven gears 10 reverse, driving the movable plates 11 to rotate and reset, so that they no longer clamp and fix the drainage tube body 1.

[0035] Embodiment 2: Different from Embodiment 1, in this embodiment, the sealing gaskets 17 on the first docking ring 4 and the second docking ring 5 can improve the sealing performance between the connecting pipe 3 and the drainage tube body 1. Specifically, as shown in the figure, a cutting piece 6 is installed inside the connecting pipe 3. Sealing gaskets 17 are embedded on the opposite surfaces of the first docking ring 4 and the second docking ring 5. The sealing gaskets 17 can improve the sealing performance between the drainage tube body 1 and the connecting pipe 3.

[0036] When the connecting pipe 3 is installed on the drainage tube body 1, the provided sealing gaskets 17 can improve the sealing performance between the connecting pipe 3 and the drainage tube body 1. Then, when the liquid in the patient's body is drawn out from the drainage tube body 1, the cutting piece 6 provided inside the connecting pipe 3 can cut the lumpy viscous liquid in the drawn-out liquid to prevent the lumpy viscous liquid from blocking the drainage tube body 1.

[0037] Embodiment 3: Different from Embodiment 2, in this embodiment, by pulling the limit block 15, the limit on the clamping block 14 can be released, facilitating the removal of the connecting pipe 3 and cleaning its interior. Specifically, refer to Figure 1 and Figure 3 and Figures 5 - 7 As shown, clamping blocks 14 are fixedly arranged at equal angles on one side of the first docking ring 4, and grooves are formed on the side surfaces of the clamping blocks 14. Slots 13 are formed at equal angles on the side of the second docking ring 5 away from the connecting pipe 3. The positions of the clamping blocks 14 and the slots 13 correspond one by one, and the clamping blocks 14 and the slots 13 are in snap connection. A limit block 15 is slidably connected inside the second docking ring 5 above the slot 13. A return spring 16 is installed between the outer side of the limit block 15 and the inner wall of the second docking ring 5. The right sides of the clamping blocks 14 and the ends of the limit block 15 are both inclined, and the inclined surfaces of the clamping blocks 14 and the limit block 15 are in contact with each other. The limit block 15 and the groove are in snap connection.

[0038] When the connecting pipe 3 needs to be removed, the medical staff only need to pull the limit block 15 to separate it from the groove, release the limit on the clamping block 14, and then separate the clamping block 14 from the slot 13, thereby facilitating the removal of the connecting pipe 3 and cleaning the internal cutting piece 6. Then, the medical staff insert the clamping blocks 14 on the first docking ring 4 into the slots 13 on the second docking ring 5. At the same time, the clamping blocks 14 squeeze the limit block 15 to make it move. As the clamping blocks 14 extend into the slots 13, the grooves on the clamping blocks 14 move to the position of the limit block 15. At this time, the elastic force of the return spring 16 drives the limit block 15 to insert into the groove, which can limit the clamping block 14 and complete the installation of the connecting pipe 3.

[0039] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0040] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
