Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a drainage tube clamping device. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage. It is made of materials such as silicone rubber or polyurethane. Its main function is to guide pus, blood, or fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infections and promote wound healing. During a surgical operation, in order to drain exudate, blood, or other fluids from the surgical site and prevent these fluids from accumulating in the body, which may cause infections or affect wound healing, doctors usually place a drainage tube for the patient. For example, patients after abdominal organ surgeries such as those of the gastrointestinal tract, liver, spleen, gallbladder, and pancreas often need to have an abdominal drainage tube placed.

[0003] After the drainage tube is placed, it is fixed outside the skin. When the fluid in the drainage cavity does not need to be drained, the drainage tube needs to be clamped. Currently, the common method of clamping the drainage tube is to use a simple clip for clamping. After clamping, due to the structure of the clip itself, long-term placement on the patient's skin can cause pressure sores on the patient's skin. At the same time, when the patient moves, the clip is easily touched and may fall off, which easily leads to clamping failure. At the same time, unilateral clamping may still cause liquid leakage during clamping. Also, the clamping is a simple on / off clamping and cannot be clamped or the drainage rate adjusted as needed. The current clamping method still has certain defects.

[0004] Therefore, a drainage tube clamping device is needed to solve the above technical problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention discloses a drainage tube clamping device, including: a fixing plate and a fixing component. A cylindrical groove is opened in the middle of the upper end of the fixing plate, and a threaded hole is opened at the lower end of the cylindrical groove. The fixing component is movably installed on the threaded hole. On the side wall of the fixing plate, a through hole is opened at the upper end of the bottom of the groove, and a circular hole corresponding to the height of the through hole is opened on the fixing component. On both sides of the fixing component, a limiting block is fixedly installed on the side wall of the fixing plate. The limiting block has a linear non-uniform length structure and gradually increases from one end of the through hole to the other end. By rotating the fixing component, the drainage tube moves towards the limiting block to achieve adjustment while clamping.

[0006] Further, the fixing component includes: a rotating block, a rotating rod, and a pressing head. The lower end of the rotating rod is threadedly connected to the threaded hole, and the rotating block is fixedly installed at the upper end of the rotating rod. The circular hole penetrates through the inside of the rotating rod. The drainage tube passes through the through hole, the circular hole, and the through hole in sequence to form a limit between the rotating rod and the groove.

[0007] Further, a pressing head is fixedly installed in the middle of the rotating rod, and a clamping plate is fixedly installed at the end of the pressing head.

[0008] Further, a plurality of indicating blocks are arranged in a circumferential array at the upper end of the fixing plate. The color of the indicating blocks gradually deepens in the clockwise direction. An indicating arrow is arranged between the indicating blocks, and the lower end of the fixing plate is provided with an arc-shaped structure.

[0009] Further, the end of the rotating block is provided with a tip for indicating the indicating block.

[0010] The beneficial effects of the present invention are as follows:

[0011] The present invention designs a drainage tube clamping device, including a fixing plate and a fixing component. A cylindrical groove is opened in the middle of the upper end of the fixing plate, and a threaded hole is opened at the lower end of the cylindrical groove. The fixing component is movably installed on the threaded hole. On the side wall of the fixing plate, a through hole is opened at the upper end of the bottom of the groove, and a round hole corresponding to the height of the through hole is opened on the fixing component. On both sides of the fixing component, a limiting block is fixedly installed on the side wall of the fixing plate. The limiting block has a linear non-uniform length structure and gradually increases from one end of the through hole to the other end. By rotating the fixing component, the drainage tube moves towards the limiting block to achieve adjustment and clamping at the same time. The drainage tube can be fixed by the provided fixing component, and after fixing, rotation can effectively form a clamping effect. Moreover, the clamping is not a direct linear clamping. When clamping, a Z-shaped clamping effect can be achieved, which can better clamp the drainage tube. In addition, due to the threaded connection relationship, the position of the rotating rod can be directly adjusted by rotation, thereby realizing the adjustment of the clamping effect on the drainage tube, making it possible to be used as a structure for adjusting the drainage speed.

[0012] At the same time, according to the rotation to adjust the position of the rotating rod, a plurality of indicating blocks are arranged in a circumferential array at the upper end of the fixing plate, and the color of the indicating blocks gradually deepens in the clockwise direction, enabling patients or doctors to directly adjust the drainage speed or close according to the color. The color setting is more user-friendly for elderly and child patients. Description of the Drawings

Specific implementation mode

[0023] Example 1

[0024] A drainage tube clamping device, comprising: a fixing plate 1 and a fixing component 2. A cylindrical groove 11 is formed in the middle of the upper end of the fixing plate 1, and a threaded hole 15 is formed at the lower end of the cylindrical groove 11. The fixing component 2 is movably installed on the threaded hole 15. On the side wall of the fixing plate 1, a through hole 13 is formed at the upper end of the bottom of the groove. A round hole 221 is formed on the fixing component 2 corresponding to the height of the through hole 13. On both sides of the fixing component 2, a limiting block 3 is fixedly installed on the side wall of the fixing plate 1. The limiting block 3 has a linear non-uniform length structure and gradually increases from one end of the through hole 13 to the other end. By rotating the fixing component 2, the drainage tube 4 moves towards the limiting block 3 to achieve adjustment and can be clamped at the same time. By rotating the fixing component 2, the drainage tube 4 moves towards the limiting block 3 to achieve adjustment and can be clamped at the same time. The fixing component 2 can fix the drainage tube 4, and after fixing, rotation can effectively form a clamping effect. And the clamping is not a direct linear clamping. When clamping, a Z-shaped clamping effect can be achieved, which can better clamp the drainage tube 4. In addition, due to the threaded connection relationship, the position of the rotating rod 22 can be directly adjusted by rotation, thereby realizing the adjustment of the clamping effect on the drainage tube 4, so that it can be used as a structure for adjusting the drainage speed. Specifically, the fixing component 2 includes: a rotating block 21, a rotating rod 22, and a pressing head 23. The lower end of the rotating rod 22 is threadedly connected to the threaded hole 15, and the rotating block 21 is fixedly installed at the upper end of the rotating rod 22. The round hole 221 penetrates through the inside of the rotating rod 22. The drainage tube 4 passes through the through hole 13, the round hole 221, and the through hole 13 in sequence to form a limit between the rotating rod 22 and the groove. Specifically, as Figure 1 and Figure 4 shown, after rotating the rotating rod 22, the drainage tube 4 will be gradually limited to form a clamping device. At the same time, the upper and lower through holes 13 during clamping cause the drainage tube 4 to be clamped into a Z-shaped structure, which can form a better fixing effect compared to the traditional linear clamping structure. At the same time, when clamping, the drainage tube 4 will shrink inward by a certain distance. In order to prevent the shrinkage of the drainage tube 4 from causing the drainage tube 4 to come out during shrinkage, during use, the length of the drainage tube 4 needs to be controlled so that it will not directly pull the drainage tube 4 during fixation and cause it to come out directly;

[0025] In addition, in this embodiment, based on the above-mentioned rotation and fixation structure, a pressing head 23 is fixedly installed in the middle of the rotating rod 22, and a clamping plate 24 is fixedly installed at the end of the pressing head 23. The pressing head 23 and the clamping plate 24 can effectively clamp and fix the internal drainage tube 4. When in use, directly pressing the pressing head 23 can make the internal clamping plate 24 clamp the drainage tube 4, and it can be released after this pressing; to ensure that the above process can be realized, the structural principle of the pressing head 23 is the principle of a click pen (the specific structure and principle belong to the prior art and will not be described in detail here); at the same time, in order to form a limiting effect after effective fixation, a fixing belt can be set on the fixing plate 1, which is wound around the patient for one week so that it can be used as a limiting device.

[0026] Embodiment 2

[0027] In this embodiment, a plurality of indicating blocks 12 are circumferentially and arrayedly arranged at the upper end of the fixing plate 1. The color of the indicating blocks 12 gradually deepens in the clockwise direction. An indicating arrow 14 is arranged between the indicating blocks 12, so that patients or doctors can directly adjust the drainage speed or close it according to the color, and the color setting is more user-friendly for elderly and child patients. The lower end of the fixing plate 1 is set as an arc structure. The arc structure can well fit the skin of the user. At the same time, a silica gel pad can be installed on the arc-shaped surface of the fixing plate 1 to effectively protect the skin of the patient;

[0028] At the same time, in order to enable the user to understand whether the current rotation position is in the current-limiting or fixed state, the end of the rotating block 21 is set as a tip 211, and the tip 211 is used to indicate the indicating block 12.
