Description

Technical Field

[0001] This utility model relates to the field of medical devices for hepatobiliary surgery, specifically a drainage device. Background Technology

[0002] Hepatobiliary surgical drainage involves draining blood, bile, secretions, and other fluids accumulated in the body cavity from their original location to prevent them from accumulating in the body cavity and causing secondary compression symptoms, infection, or tissue damage. Therefore, drainage tubes are required. Drainage tubes are mostly made of medical latex material, which is soft in texture. In actual use, drainage tubes have the following problems: (1) Excessive bending of the drainage tube causes the tube wall to adhere, blocking or narrowing the internal flow channel of the drainage tube, thus affecting drainage and the normal medical process. (2) When the fluid in the patient's body is too viscous, the viscous fluid in the patient's body will cause a certain degree of blockage to the drainage tube, thus affecting drainage and the normal medical process.

[0003] In a published Chinese patent application (publication number CN221014146U), titled "A Drainage Tube," the prior art discloses a drainage tube body with an internal anti-bending component. This component includes three metal wires embedded within the tube body, all fitting snugly against the inner wall. The lines connecting the cross-sections of the three wires form an equilateral triangle. Several metal wire loops are evenly spaced and connected between the three wires. The wires and loops are made of flexible metal wire. This prior art uses the three metal wires and loops to support the tube body, ensuring that while the tube is fully extended, the inherent flexibility of the wires prevents excessive bending and folding that could cause blockage. Although this prior art effectively supports the tube body and prevents blockage of the internal flow channels, its implementation has certain limitations. A metal support structure is installed inside the tube, and the metal is in direct contact with the effusion. Since the effusion may flow backward, it is difficult to ensure the patient's hygiene. At the same time, the existing technology cannot effectively solve the above problems (2).

[0004] In summary, this case is proposed to address the limitations of existing technologies. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the present invention provides a drainage device that solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drainage device comprising a flexible tube, a blockage-clearing component, and a spring. The spring has a bore diameter larger than the outer diameter of the flexible tube and is sleeved on the outer wall of the flexible tube. The blockage-clearing component is sleeved on the outer wall of the flexible tube and the two are slidably connected. The blockage-clearing component is located at one end of the spring. The blockage-clearing component comprises a cylindrical body, two rollers, and two sliding blocks. The two sliding blocks are respectively inserted at both ends of the cylindrical body and are slidably connected to the cylindrical body. The rollers are rotatably disposed at one end of the sliding blocks. Through holes are provided on both sides of the cylindrical body, and the flexible tube passes through the through holes in the cylindrical body. Both rollers are located inside the cylindrical body and are located on both sides of the flexible tube.

[0009] Optionally, the hose includes a first hose, a drip pot, and a second hose. One end of the first hose is fixedly connected to one end of the drip pot and the two are in communication. The other end of the first hose is fixedly connected to a first connector and the two are in communication. One end of the second hose is fixedly connected to the other end of the drip pot and the two are in communication. The other end of the second hose is fixedly connected to a second connector and the two are in communication.

[0012] Optionally, two support bars are fixedly connected to one side wall of the sliding block, and the two ends of the central shaft of the roller are rotatably connected to the two support bars respectively; a limiting protrusion is fixedly connected to one side wall of the sliding block, and a sliding groove is provided on the inner side wall of the cylinder, and the limiting protrusion is slidably disposed in the sliding groove of the cylinder.

[0013] Optionally, the wire diameter of the spring ranges from 1 mm to 5.5 mm.

[0014] (III) Beneficial Effects

[0015] This utility model provides a drainage device, which has the following beneficial effects:

[0016] This drainage device, through the coordinated arrangement of a flexible hose, a clearing component, and a spring, effectively prevents excessive bending of the hose and clears internal blockages. By sleeved on the outer wall of the hose, the spring provides external support. Due to its elasticity and rigidity, the spring can straighten the hose promptly, preventing excessive bending and thus avoiding hose wall adhesion, blockage, or narrowing of the internal flow channel, thereby achieving normal drainage. When the flow channel is blocked by viscous material, pressing and sliding the clearing component along the length of the hose compresses the hose, expelling the blockage and clearing it.

[0025] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying anything.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] Example 1, please refer to Figures 1 to 6 This utility model provides a technical solution: a drainage device, including a flexible tube, a blockage-clearing component 2, and a spring. The diameter of the spring's orifice is larger than the outer diameter of the flexible tube, and the spring is sleeved on the outer wall of the flexible tube. The blockage-clearing component 2 is sleeved on the outer wall of the flexible tube and the two are slidably connected. The blockage-clearing component 2 is located at one end of the spring.

[0028] The tubing, also known as the drainage tube, is made of medical-grade latex. The spring has a certain degree of elasticity and rigidity. When one end of the spring is pushed, it can slide along the axial direction of the tubing, thus being compressed.

[0029] By placing a spring on the outer wall of the hose, the hose is externally supported. Due to the spring's elasticity and rigidity, it can straighten the hose in time, preventing excessive bending and thus avoiding the hose's internal wall from sticking together. This prevents the flow channel inside the hose from being blocked or narrowed, thereby achieving the purpose of normal drainage.

[0030] When the flow channel inside the hose is blocked by viscous material, press the sliding unblocking component 2 to make it slide along the length of the hose. The unblocking component 2 compresses the spring and squeezes the hose during the sliding process, thereby squeezing out the viscous blockage inside the hose and achieving the purpose of cleaning the viscous blockage inside the hose.

[0031] Specifically, the unblocking component 2 includes a cylinder 201, two rollers 204, and two sliding blocks 202. The two sliding blocks 202 are respectively inserted at both ends of the cylinder 201 and are slidably connected to the cylinder 201. Each roller 204 is rotatably mounted at one end of a sliding block 202. Through holes 203 are formed on both side walls of the cylinder 201, through which a flexible hose passes, and the cylinder 201 is slidably connected to the flexible hose. Both rollers 204 are located inside the cylinder 201, and are positioned on either side of the flexible hose.

[0032] The cylinder 201, two rollers 204, and two sliding blocks 202 are all made of lightweight plastic. When clearing blockages, medical staff press the two sliding blocks 202 with their index finger and thumb respectively. The two sliding blocks 202 slide closer together inside the cylinder 201, pushing the two rollers 204 closer together, and the rollers 204 squeeze the tubing, causing the inner wall of the tubing to adhere. Then, the entire unblocking component 2 is immediately pulled, causing it to slide along the length of the tubing. The unblocking component 2 pushes the compression spring. At this time, the two rollers 204 crush the tubing during movement, squeezing out the viscous blockage inside the tubing, thus achieving the purpose of unblocking. After unblocking, the index finger and thumb are no longer pressing the two sliding blocks 202. After the two rollers 204 lose pressure, the tubing returns to its original position, the internal flow channel of the tubing is opened, and at the same time, the tubing pushes the two rollers 204 and the two sliding blocks 202 away from each other. Subsequently, the spring force pushes the unblocking component 2 back to the starting position.

[0033] More specifically, two support bars 205 are fixedly connected to one side wall of the sliding block 202, and the two ends of the central shaft of the roller 204 are rotatably connected to the two support bars 205 respectively. A limiting protrusion 206 is fixedly connected to one side wall of the sliding block 202, and a sliding groove is provided on the inner side wall of the cylinder 201, and the limiting protrusion 206 is slidably disposed in the sliding groove of the cylinder 201.

[0034] Two support bars 205 are used to support and fix the roller 204, which can rotate on the two support bars 205. The limiting protrusion 206 is used to limit the sliding block 202 and prevent the sliding block 202 from slipping off the cylinder 201.

[0035] Specifically, the wire diameter of the spring ranges from 1 mm to 5.5 mm.

[0036] The spring's aperture is larger than the hose's outer diameter, allowing it to fit snugly onto the hose's outer wall. The spring is made of steel wire with a diameter between 1mm and 5.5mm, resulting in low overall cost while ensuring the hose remains straight and preventing excessive bending.

[0037] Example 2, please refer to Figures 1 to 5 The main difference between this embodiment and Embodiment 1 is that the hose includes a first hose 4, a drip pot 1, and a second hose 7. One end of the first hose 4 is fixedly connected to one end of the drip pot 1 and the two are in communication. The other end of the first hose 4 is fixedly connected to a first connector 3 and the two are in communication. One end of the second hose 7 is fixedly connected to the other end of the drip pot 1 and the two are in communication. The other end of the second hose 7 is fixedly connected to a second connector 6 and the two are in communication.

[0038] The drip chamber 1 is made of medical latex material. The internal flow channels of the first connector 3, first tubing 4, drip chamber 1, second tubing 7, and second connector 6 are sequentially connected, allowing the patient's internal fluid to flow within these channels. In practice, the first connector 3 is used to mate with the puncture needle tubing, which is inserted into the patient's body with its end positioned at the site of the internal fluid. The second connector 6 is used to mate with a receiving bag, a plastic sanitary bag used to collect the patient's excreted fluid. When draining the patient's internal fluid, the receiving bag is positioned below the patient's body (specifically, below the height of the internal fluid; if the patient is lying on the bed, the receiving bag is below the bed frame). Slowly squeezing the drip chamber 1 causes the patient's internal fluid to flow sequentially through the puncture needle tubing, first connector 3, first tubing 4, drip chamber 1, second tubing 7, and second connector 6 into the receiving bag, thus draining the patient's internal fluid.

[0039] The spring includes a first spring 5 and a second spring 8. The first spring 5 is sleeved on the outer wall of the first hose 4, and the second spring 8 is sleeved on the outer wall of the second hose 7.

[0040] The first spring 5 provides external support for the first hose 4. Under the action of its own elasticity and rigidity, the first spring 5 can straighten the first hose 4 in time. That is, the elastic restoring ability of the first spring 5 can straighten the first hose 4 and prevent the first hose 4 from being excessively bent.

[0041] The second spring 8 provides external support for the second hose 7. Under the action of its own elasticity and rigidity, the second spring 8 can straighten the second hose 7 in time. That is, the elastic restoring ability of the second spring 8 can straighten the second hose 7 and prevent the second hose 7 from being excessively bent.

[0042] Specifically, there are two unblocking components 2, which are respectively sleeved on the outer walls of the first hose 4 and the second hose 7. The unblocking components 2 are slidably connected to the first hose 4 or the second hose 7.

[0043] Among them, the two unblocking components 2 are used to unblock the first hose 4 and the second hose 7 respectively.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
