Description

Technical Field

[0001] The utility model relates to a regulator, specifically to a liquid flow rate regulator for a drainage bag. Background Technique

[0002] A drainage bag is a medical device mainly used to collect liquids in the human body, such as ascites or wound exudate. It is usually connected to a catheter or drainage tube, enabling these liquids to flow smoothly into the bag, facilitating the observation of the color, nature, and quantity of the liquid, thereby helping doctors evaluate the patient's condition. The liquid flow rate regulator of the drainage bag is an important part of the drainage bag, mainly used to control the flow rate of the drained liquid. There are many existing technologies for the flow rate adjustment structure of the drainage bag:

[0003] For example, a new type of drainage tube speed limiter with the Chinese patent publication number CN219022471U includes a speed limiter housing. Hook slots are provided at both ends of the speed limiter housing. Fixed hooks are arranged inside the hook slots. Springs are connected to the lower ends of the fixed hooks. Adjusting bolts are provided at the lower ends of the hook slots. A drainage tube slot is arranged in the middle of the speed limiter housing. Coarse thread adjusting bolts and fine thread adjusting bolts are respectively arranged at the upper and lower ends of the drainage tube slot. Adjusting handles and speed limiting heads are arranged on both the coarse thread adjusting bolts and the fine thread adjusting bolts. With the cooperation of the speed limiter housing and the fixed hooks, the speed limiter of the present utility model can be quickly installed on the drainage tube, suitable for different drainage situations. Different precision speed limit adjustments can be carried out through the coarse thread adjusting bolts and the fine thread adjusting bolts, making the adjustment of the drainage flow rate more precise, improving the safety of drainage, and meeting the usage requirements of different patients, which is worthy of promotion;

[0004] Currently, most of the liquid flow rate regulators of drainage bags install the speed limiter housing on the surface of the drainage tube through fixed hooks. Most drainage bags are installed in a hanging manner, making the drainage tube vertically placed during the working state. When the patient moves or is active, the flow rate regulator installed on the surface of the drainage tube is likely to fall off or shift due to external forces, thereby affecting the control effect of the flow rate of the drainage bag. In view of this, we propose a liquid flow rate regulator for a drainage bag. Content of the Utility Model

[0005] The purpose of the present utility model is to solve the above-mentioned drawbacks and provide a liquid flow rate regulator for a drainage bag that can adjust the liquid flow rate inside the drainage tube body while improving the stability of the regulator through an adjusting tube body arranged in the middle of the drainage tube body and an adjusting component inside it.

[0006] By providing an adjustment tube body in the middle of the drainage tube body and an adjustment component inside it, the stability of the regulator can be improved while adjusting the liquid flow rate inside the drainage tube body. At the same time, by providing a limiting component at the bottom end of the adjustment component, the flow tightness of the adjustment tube body can be further improved without affecting the overall use of the device.

[0007] Therefore, the present utility model provides a drainage bag liquid flow rate regulator, which includes an adjustment tube body installed in the middle of the drainage tube body. One side of the drainage tube body is connected to the inlet of the drainage bag body. An adjustment component for adjusting the flow rate inside the drainage tube body is installed inside the adjustment tube body, and a limiting component for improving the tightness inside the drainage tube body is installed at the bottom end of the adjustment component.

[0008] As a further improvement of this technical solution, the adjustment component includes a collar installed on the inner wall of the adjustment tube body. A flow-through rod is slidably arranged inside the collar. The inside of the flow-through rod is a hollow structure. A plurality of flow holes are formed on the upper surface of the flow-through rod. Adjustment sliding holes are formed on both sides of the outer wall of the adjustment tube body. Starting rods are slidably arranged inside the two adjustment sliding holes. One end of each of the two starting rods is fixedly installed on the lower surface of the flow-through rod.

[0009] As a further improvement of this technical solution, the limiting component includes a limiting ring plate fixedly installed at the lower end of the collar. A limiting groove is formed on the inner wall of the limiting ring plate. A limiting clamping plate that fits the inner wall of the limiting groove is installed on the outer wall of the flow-through rod.

[0010] As a further improvement of this technical solution, anti-slip plates are fixedly installed at the ends of the two starting rods extending out of the adjustment sliding holes. The surface of the anti-slip plates is made of a rough material. The surfaces of the two anti-slip plates close to the starting rods are in contact with the outer wall of the adjustment tube body.

[0011] As a further improvement of this technical solution, the collar is formed by splicing a fixed ring and a sealing gasket. The surface of the sealing gasket is fitted and installed on the inner wall of the fixed ring.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In this drainage bag liquid flow rate regulator, through the drainage tube body and the drainage bag body, the drainage device can operate normally. By using the adjustment tube body provided in the middle of the drainage tube body and the adjustment component inside it, the liquid flow rate inside the drainage tube body can be adjusted. The adjustment tube body is installed in the middle of the drainage tube body, reducing the situation of the regulator falling off. By providing a limiting component at the bottom end of the adjustment component, the flow tightness of the adjustment tube body can be further improved without affecting the overall use of the device.

[0026] Currently, most of the flow rate regulators of drainage bags install the speed limiter housing on the surface of the drainage tube through fixed hooks, and most drainage bags are installed in a hanging manner, making the drainage tube vertically placed during operation. When the patient moves or activities, the flow rate regulator installed on the surface of the drainage tube is likely to fall off or shift due to external forces, thus affecting the control effect of the flow rate of the drainage bag.

[0027] Please refer to Figures 1 - 5 As shown, the device includes an adjustment tube body 1, the adjustment tube body 1 is installed in the middle of the drainage tube body 11, one side of the drainage tube body 11 is connected to the inlet of the drainage bag body 12, and an adjustment component 2 for adjusting the flow rate inside the drainage tube body 11 is installed inside the adjustment tube body 1, and a limit component 3 for improving the sealing performance inside the drainage tube body 11 is installed at the bottom end of the adjustment component 2.

[0028] First, the specific structure of the adjustment component 2 is disclosed. The adjustment component 2 includes a collar 21 installed on the inner wall of the adjustment pipe body 1. A flow-through rod 22 is slidably arranged inside the collar 21. The inside of the flow-through rod 22 is a hollow structure. A number of flow holes 23 are formed on the upper surface of the flow-through rod 22. Adjustment sliding holes 25 are formed on both sides of the outer wall of the adjustment pipe body 1. Starting rods 24 are slidably arranged inside the two adjustment sliding holes 25. One end of each of the two starting rods 24 is fixedly installed on the lower surface of the flow-through rod 22. When the liquid inside the drainage pipe body 11 needs to increase the flow rate, the two starting rods 24 are slid upward inside the adjustment sliding holes 25, driving the flow-through rod 22 connected to the two starting rods 24 to move upward inside the collar 21, increasing the exposed size of the flow holes 23, and then increasing the flow rate of the liquid inside the drainage pipe body 11. When it is necessary to reduce the flow rate, the starting rods 24 are slid in the reverse direction, reducing the exposed size of the flow holes 23, and the effect of reducing the flow rate can be achieved.

[0029] Secondly, the specific structure of the limiting component 3 is disclosed. The limiting component 3 includes a limiting ring plate 31 fixedly installed at the lower end of the collar 21. A limiting groove 33 is formed on the inner wall of the limiting ring plate 31. A limiting clamping plate 32 that fits the inner wall of the limiting groove 33 is installed on the outer wall of the flow-through rod 22. By using the limiting clamping plate 32 installed on the outer wall of the flow-through rod 22 to be clamped inside the limiting groove 33, when the flow-through rod 22 slides, the limiting clamping plate 32 can be driven to slide inside the limiting groove 33, and then the function of limiting the sliding position of the flow-through rod 22 is achieved, avoiding the situation that the entire flow hole 23 slides out of the collar 21.

[0030] The improvement of this embodiment lies in: First, through the drainage pipe body 11 and the drainage bag body 12, the drainage device can operate normally. When the liquid inside the drainage pipe body 11 needs to increase the flow rate, the two starting rods 24 are slid upward inside the adjustment sliding holes 25, driving the flow-through rod 22 connected to the two starting rods 24 to move upward inside the collar 21, increasing the exposed size of the flow holes 23, and then increasing the flow rate of the liquid inside the drainage pipe body 11. When it is necessary to reduce the flow rate, the starting rods 24 are slid in the reverse direction, reducing the exposed size of the flow holes 23, and the effect of reducing the flow rate can be achieved. Among them, the adjustment pipe body 1 is located in the middle of the drainage pipe body 11, reducing the situation of the regulator falling off;

[0031] By using the limiting clamping plate 32 installed on the outer wall of the flow-through rod 22 to be clamped inside the limiting groove 33, when the flow-through rod 22 slides, the limiting clamping plate 32 can be driven to slide inside the limiting groove 33, and then the function of limiting the sliding position of the flow-through rod 22 is achieved, avoiding the situation that the entire flow hole 23 slides out of the collar 21.

[0032] Considering the fixing condition of the flow-through rod 22 when the starting rod 24 drives the flow-through rod 22 to adjust the exposed size of the flow-through hole 23, therefore, in order to further improve the fixing effect on the flow-through rod 22, by Figures 2 - 3 As shown, anti-slip plates 4 are fixedly installed at one end of the two starting rods 24 extending out of the adjusting sliding holes 25. The surface of the anti-slip plates 4 is made of a rough material, and the surfaces of the two anti-slip plates 4 on the side close to the starting rods 24 are both attached to the outer wall of the adjusting pipe body 1.

[0033] The improvement lies in: using the anti-slip plates 4 installed at the ends of the starting rods 24, and the surfaces of the anti-slip plates 4 being made of a rough material, so that the friction force between the anti-slip plates 4 and the outer wall of the adjusting pipe body 1 is increased, reducing the situation of random sliding of the anti-slip plates 4, and then improving the stability of the flow-through rod 22.

[0034] When the flow-through rod 22 is inserted into the inside of the collar 21, part of the flow-through holes 23 will be located inside the collar 21. Therefore, in order to improve the sealing effect on the flow-through holes 23, by Figures 3 - 4 As shown, the collar 21 is formed by splicing a fixed ring 5 and a sealing gasket 51, and the surface of the sealing gasket 51 is fitted and installed on the inner wall of the fixed ring 5.

[0035] The improvement lies in: using the collar 21 formed by splicing the fixed ring 5 and the sealing gasket 51, and the sealing gasket 51 being located inside the fixed ring 5, so that the outer wall of the flow-through rod 22 can be attached to the inner wall of the sealing gasket 51, and then the flow-through holes 23 can be assisted in sealing, improving the overall sealing performance of the drainage device.

[0036] In summary, the working principle of this solution is as follows: First, through the drainage pipe body 11 and the drainage bag body 12, the drainage device can operate normally. When the liquid inside the drainage pipe body 11 needs to increase the flow rate, slide the two starting rods 24 upward inside the adjusting sliding holes 25, drive the flow-through rod 22 connected to the two starting rods 24 to move upward inside the collar 21, increasing the exposed size of the flow-through holes 23, and then increasing the flow rate of the liquid inside the drainage pipe body 11. When it is necessary to reduce the flow rate, slide the starting rod 24 in the reverse direction, so that the exposed size of the flow-through holes 23 is reduced, and the effect of reducing the flow rate can be achieved. Among them, the adjusting pipe body 1 is located in the middle of the drainage pipe body 11, reducing the situation of the regulator falling. Using the anti-slip plates 4 installed at the ends of the starting rods 24, the friction force between the anti-slip plates 4 and the outer wall of the adjusting pipe body 1 is increased, reducing the situation of random sliding of the anti-slip plates 4, and then improving the stability of the flow-through rod 22;

[0037] The limiting clamping plate 32 installed on the outer wall of the circulation rod 22 is clamped inside the limiting groove 33. When the circulation rod 22 slides, it can drive the limiting clamping plate 32 to slide inside the limiting groove 33, thereby achieving the function of limiting the sliding position of the circulation rod 22 and avoiding the situation that the entire circulation hole 23 slides out of the collar 21.

[0038] The collar 21 is formed by splicing the fixed ring 5 and the sealing gasket 51, and the sealing gasket 51 is located inside the fixed ring 5, so that the outer wall of the circulation rod 22 can be attached to the inner wall of the sealing gasket 51, thereby assisting in sealing the circulation hole 23 and improving the overall sealing performance of the drainage device.
