Description

Technical Field

[0001] The invention relates to the field of medical equipment, in particular to a drainage tube for extracting effusion. Background Art

[0002] The Department of Endocrinology is a place in the hospital that specializes in the treatment of endocrine diseases. It is mainly responsible for the clinical diagnosis and treatment of diabetes, obesity, osteoporosis, gout, lipid metabolism disorders, and diseases of the thyroid, pituitary, adrenal glands, gonads, parathyroid glands, etc.

[0003] In clinical treatment, drainage is often required to discharge the accumulated fluid in the human body. Drainage is the process and method of extracting fluid from a body cavity or wound by gravity. It is often used in the medical clinical field and nursing. The general gauze strip drainage is to put the sterile gauze strip into the shallow wound or the incised abscess cavity, and leave one end outside the wound to drain the wound fluid. The drainage quality is not high, it irritates the tissue and may cause infection. The ordinary rubber tube drainage is to insert a latex tube with several small holes cut on one end into the deep wound cavity or body cavity. Compared with gauze drainage, the drainage quality is better.

[0004] The pleural effusion drainage tube used in the hepatology department is mainly used to drain the air or liquid in the thoracic cavity. The drainage head of the existing pleural effusion drainage tube used in the hepatology department is round, and a plurality of small holes are often opened on its side wall to prevent clogging. However, the size of such small holes is small, and human tissues are easily sucked in, and the anti-clogging effect is not ideal, which not only increases the workload of nurses, but also increases the chance of chest infection, causing unnecessary pain to patients.

[0005] For example, a pleural effusion drainage tube for hepatology mentioned in the utility model patent with announcement number CN205626694U includes: a tube body, an end of which is provided with a terminal; the terminal includes an inner drainage tube and an outer support tube coaxially arranged, and a connecting rib connecting the outer support tube to the inner drainage tube, the inner drainage tube is connected to the tube body, at least one first drainage hole is provided on the wall of the inner drainage tube along its axial direction, a drainage groove is provided on the wall of the outer support tube along its axial direction, a second drainage hole is provided on the outer support tube, the second drainage hole is located at each connecting rib, and penetrates the connecting rib and the inner drainage tube; the end of the terminal is a suction hole, an image capture module is provided at the suction hole of the terminal, a wireless transmitter is provided on the image capture module, and the image capture module transmits image data to an external control and display device through the wireless transmitter. The utility model has a simple structure, is easy to use, and accurately positions the suction effusion, effectively alleviating the pain of patients.

[0006] Due to its image capture module, the structure of the drainage tube is complicated, which greatly increases the cost of the drainage tube and is not conducive to large-scale promotion. Summary of the invention

[0007] The object of the present invention is to provide a drainage tube for extracting effusion, which has low cost and good anti-blocking effect.

[0008] To achieve the above object, the present invention provides the following technical solution: a drainage tube for extracting effusion, comprising a drainage tube, drainage holes are evenly arranged on the tube wall of the drainage tube, a filter screen is arranged inside the drainage tube, and the drainage tube is detachably connected with a mounting sleeve;

[0009] The mounting sleeve is provided with a mounting groove connected with the drainage hole, the mounting sleeve is connected with a guide sleeve near the free end of the drainage tube, the other end of the mounting sleeve is connected with a mounting seat, the mounting seat is provided with a first lifting device, the first lifting device is connected with a cone assembly, a plurality of the cone assemblies form a complete cone, and the cone assembly is connected with the guide sleeve;

[0010] The first lifting device includes a first cavity, the first cavity is evenly connected with a first piston hole corresponding to the cone assembly, a first piston is sealingly and slidably connected in the first piston hole, the first piston is connected to the cone assembly, and the first cavity is connected with a pressurizing mechanism.

[0011] Through the above technical scheme, a filter net is arranged in the drainage tube, and the filter net can prevent the tissue from entering the drainage hole, thereby avoiding the drainage hole from being blocked, thereby playing an anti-blocking role; when the first lifting device is not opened, the cone assembly forms a complete cone, and since the cone has a guiding function, the resistance is very small when the entire drainage tube enters the tissue, and it is easy to reach the predetermined position; when the first lifting device is opened, a gap is opened between the cone assembly and the cone assembly. At this time, since there is friction between the tissue and the cone assembly, the tissue is driven by the cone assembly to move to both sides of the gap, so it is not easy for the tissue to enter the gap. At the same time, the gap formed allows the accumulated fluid in the tissue to enter the drainage tube through the gap, the mounting groove and the drainage hole, thereby completing the drainage process.

[0012] Preferably, the filter screen is tubular and coaxially disposed in the drainage tube or embedded in the tube wall of the drainage tube.

[0013] Through the above technical solution, the filter net can prevent tissue from entering the drainage hole, thereby avoiding the drainage hole from being blocked, thereby playing an anti-blocking role. The placement positions of the two filter nets can be selected according to actual conditions.

[0014] Preferably, the pressurizing mechanism is a syringe.

[0015] Through the above technical solution, syringes are more common in hospitals and are more convenient to use, which is conducive to large-scale promotion.

[0016] Preferably, a clamping block is provided on the drainage tube, and a clamping groove which is clamped with the clamping hole is provided on the mounting sleeve.

[0017] Through the above technical solution, the connection between the drainage tube and the installation sleeve can be conveniently completed through the clamping block and the clamping groove.

[0018] Preferably, the conical surface of the cone assembly is evenly provided with guide grooves along the axial direction of the drainage tube.

[0019] Through the above technical solution, setting up the guide groove is beneficial to guide the accumulated fluid in the tissue, making the accumulated fluid easier to collect. At the same time, the guide groove can increase the friction between the cone assembly and the tissue. Therefore, when the first lifting device is opened, the tissue can be distributed to both sides of the gap by the cone assembly, thereby avoiding the tissue from entering the gap, thereby preventing the drainage hole from being blocked, and having a good anti-blocking effect.

[0020] Preferably, the guide sleeve is provided with a second lifting device connected to the cone assembly, the second lifting device includes a second cavity, the second cavity is evenly connected to a second piston hole corresponding to the cone assembly, a second piston is sealingly and slidingly connected in the second piston hole, the second piston is connected to the cone assembly, and a connecting pipe is connected between the first cavity and the second cavity.

[0021] Through the above technical solution, a second lifting device is provided, and the first and second lifting devices can move synchronously through the connecting pipe, so that the formed gap can be made more uniform, and the formed gap can be prevented from being too small and blocked by tissue.

[0022] Preferably, an expansion groove communicating with the second cavity is provided on the conical surface of the cone assembly, and the expansion groove is connected to an elastic skin for sealing the expansion groove.

[0023] Through the above technical solution, when the first lifting device and the second lifting device are opened, the elastic skin begins to expand and increase in volume. Since the space in the tissue is limited, the expanded elastic skin will gather the accumulated fluid, so that the accumulated fluid can be cleaned more thoroughly.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) A filter is provided in the drainage tube, which can prevent tissue from entering the drainage hole, thereby preventing the drainage hole from being blocked, thereby playing an anti-blocking role;

[0026] (2) When the first lifting device and the second lifting device are opened, a gap is formed between the cone components. At this time, due to the friction between the tissue and the guide groove, the tissue is driven by the cone component to move to both sides of the gap, so it is not easy for the tissue to enter the gap. At the same time, the gap formed allows the accumulated fluid in the tissue to enter the drainage tube through the gap, the installation groove and the drainage hole, thereby completing the drainage process and further enhancing the anti-blocking effect;

[0027] (3) The provision of the guide groove and the elastic skin can further converge the accumulated fluid in the tissue, thereby enabling the accumulated fluid to be cleared more thoroughly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-5 , an embodiment provided by the present invention:

[0036] A drainage tube for extracting effusion includes a drainage tube 1, drainage holes 2 are evenly arranged on the tube wall of the drainage tube 1, and a filter 3 is arranged inside the drainage tube 1. The filter 3 is tubular and coaxially arranged in the drainage tube 1 or embedded in the tube wall of the drainage tube 1. In this embodiment, the filter 3 is embedded in the tube wall of the drainage tube 1. The filter 3 can prevent tissue from entering the drainage hole 2, thereby preventing the drainage hole 2 from being blocked, thereby playing an anti-blocking role. The placement positions of the two filter nets 3 can be selected according to actual conditions.

[0037] The drainage tube 1 is provided with a clamping block 13, and the mounting sleeve 4 is provided with a clamping slot 14 that is clamped with the clamping hole. The connection between the drainage tube 1 and the mounting sleeve 4 can be conveniently completed through the clamping block 13 and the clamping slot 14.

[0038] The mounting sleeve 4 is provided with a mounting groove 5 which is connected to the drainage hole 2. The mounting sleeve 4 is connected with a guide sleeve 6 near the free end of the drainage tube 1. The other end of the mounting sleeve 4 is connected with a mounting seat 7. The mounting seat 7 is provided with a first lifting device. The first lifting device is connected with a cone assembly 8. Several cone assemblies 8 form a complete cone. In this embodiment, four cone assemblies 8 form a complete cone. The cone assembly 8 is connected to the guide sleeve 6.

[0039] The first lifting device includes a first cavity 9, which is arranged in an annular shape. The first cavity 9 is evenly connected with a first piston hole 10 corresponding to the cone assembly 8. A first piston 11 is sealingly and slidably connected in the first piston hole 10. The first piston 11 is connected to the cone assembly 8. The first cavity 9 is connected with a pressurizing mechanism 12. The pressurizing mechanism 12 is a syringe. Syringes are common in hospitals and are convenient to use, which is conducive to large-scale promotion.

[0040] The guide sleeve 6 is provided with a second lifting device connected to the cone assembly 8, the second lifting device includes a second cavity 16, the second cavity 16 is arranged in an annular shape, the second cavity 16 is evenly connected with a second piston hole 17 corresponding to the cone assembly 8, a second piston 18 is sealed and slidably connected in the second piston hole 17, the second piston 18 is connected to the cone assembly 8, and a connecting pipe 19 is connected between the first cavity 9 and the second cavity 16. The second lifting device is provided, and the first and second lifting devices can move synchronously through the connecting pipe 19, so that the gap formed can be more uniform, and the gap formed is prevented from being blocked by the tissue because it is too small.

[0041] An expansion groove 20 communicating with the second cavity 16 is provided on the conical surface of the cone assembly 8. The expansion groove 20 is arranged in an annular shape and is connected to an elastic skin 21 for sealing the expansion groove 20. When the first lifting device and the second lifting device are opened, the elastic skin 21 begins to expand and increase in volume. Due to the limited space in the tissue, the expanded elastic skin 21 will have a gathering effect on the effusion, so that the effusion can be cleaned more thoroughly.

[0042] When the first lifting device and the second lifting device are not opened, the cone assembly 8 forms a complete cone. Since the cone has a guiding function, the resistance is very small when the entire drainage tube 1 enters the tissue, and it is easy to reach the predetermined position; when the first lifting device and the second device are opened, a gap is opened between the cone assembly 8 and the cone assembly 8. At this time, since there is friction between the tissue and the cone assembly 8, the tissue is driven by the cone assembly 8 to move to both sides of the gap, so it is not easy for the tissue to enter the gap. At the same time, the gap formed allows the accumulated fluid in the tissue to enter the drainage tube 1 through the gap, the mounting groove 5 and the drainage hole 2, thereby completing the drainage process.

[0043] In addition, guide grooves 15 are evenly arranged on the conical surface of the cone assembly 8 along the axial direction of the drainage tube 1. The guide grooves 15 are arranged to guide the accumulated fluid in the tissue, making it easier to collect the accumulated fluid. At the same time, the guide grooves 15 can increase the friction between the cone assembly 8 and the tissue. Therefore, when the first lifting device is opened, the tissue can be distributed to both sides of the gap by the cone assembly 8, thereby preventing the tissue from entering the gap, thereby preventing the drainage hole 2 from being blocked, and having a good anti-blocking effect.

[0044] The steps of using the drainage tube 1 are as follows: a. the first lifting device and the second lifting device are in a closed state, and the device is placed in a designated position; b. the pressurization is performed by opening the pressurizing mechanism 12, and the first lifting device and the second lifting device are opened to start draining the accumulated fluid; c. the device is taken out. If the resistance is large, it may be that too much tissue has entered the gap. The pressurization mechanism 12 is continued to be pressurized to enlarge the gap, and the device is taken out.

[0045] In summary: (1) a filter screen 3 is provided in the drainage tube 1, and the filter screen 3 can prevent tissue from entering the drainage hole 2, thereby preventing the drainage hole 2 from being blocked, thereby playing an anti-blocking role; (2) when the first lifting device and the second lifting device are opened, a gap is formed between the cone assembly 8 and the cone assembly 8. At this time, due to the friction between the tissue and the guide groove 15, the tissue is driven by the cone assembly 8 to move to both sides of the gap, so that the tissue is not easy to enter the gap. At the same time, the gap formed allows the accumulated fluid in the tissue to enter the drainage tube 1 through the gap, the mounting groove 5 and the drainage hole 2, thereby completing the drainage process and further enhancing the anti-blocking effect; (3) The setting of the guide groove 15 and the elastic skin 21 can further produce a convergence effect on the accumulated fluid in the tissue, so that the accumulated fluid can be cleaned more thoroughly.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
