Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to an anti - detachment, anti - slip and integrally - formed compressive drainage tube. Background Art

[0002] A drainage tube is an essential instrument for drainage in clinical treatment. During clinical surgical operations, in order to prevent symptoms such as inflammation, abscess, and bacterial infection caused by the long - term retention of intraoperative effusion in the patient's body, it is necessary to drain the exudate and infected fluid in the patient's body out of the body. During the drainage process, if the drainage tube is blocked or detached, it will affect the drainage effect, resulting in the accumulation of fluid in the patient's body and inducing a series of complications such as swelling, pain, and infection.

[0003] A buckle ring for fixing a drainage tube puncture needle is proposed in CN210096489U, but when in use, the drainage tube must be placed at a certain bending angle; a method for avoiding the detachment of the drainage tube is proposed in CN106137343A. After the guiding needle punctures, it is necessary to press down the tail end cap - shaped structure, release the head fold of the fine steel wire in the pillow core, put on the anti - detachment dilatation tube to expand the muscle, and release the umbrella - shaped structure by screw extrusion. The operation process is relatively complex and has a certain degree of difficulty in use.

[0004] The inventor of the present application has previously applied for the prior application CN208905896U, which provides an anti - extrusion drainage tube, but it cannot be used in cooperation with the guiding needle during puncture, so it brings certain difficulties to the operation of medical staff. Therefore, how to better combine the compressive drainage tube with the guiding needle, facilitate the operation of medical staff, and improve the puncture success rate has become the key point for the inventor to improve. Summary of the Invention

[0005] In view of the above problems, the utility model provides an anti - detachment, anti - slip and integrally - formed compressive drainage tube, which includes a drainage tube body and a guiding needle sleeved at the end of the drainage tube. The diameter of the drainage tube body is uniform, and it is composed of a drainage section, a transition section, a compressive section, a connection section, and an anti - detachment section. The cross - sectional structures of the above five sections are different, and support structures are arranged inside the drainage section, the transition section, and the compressive section. The guiding needle is sleeved on the anti - detachment section. The drainage tube with the above structure is convenient to use and has a simple structure. The cross - shaped and strip - shaped support structures inside the tube body endow it with compressive function. The anti - detachment structure at the tail end of the guiding needle combined with the internal thread of the anti - detachment section can effectively prevent the drainage tube from detaching from the needle tip during puncture. The anti - slip grooves on the surface help to solve the problem of easy slipping when operating the guiding needle while wearing gloves, reducing the operation difficulty during use.

[0006] The specific technical solution of the utility model is as follows:

[0007] An anti - shedding and anti - skid integrally - formed compression drainage tube, comprising a drainage tube body and a guiding needle sleeved at the end of the drainage tube. The diameter of the drainage tube body is uniform, and it consists of a drainage section, a transition section, a compression section, a connection section, and an anti - shedding section. The cross - sectional structures of the above - mentioned five sections are different, and support structures are arranged inside the drainage section, the transition section, and the compression section. The guiding needle is sleeved on the anti - shedding section.

[0008] Specifically, the drainage section is a cross - shaped tube with an outer groove, and its rear side gradually changes into a transition section with a cross - shaped cross - section; the rear end of the transition section is connected to a compression section, which has a strip - shaped convex support structure inside; the connection section is a circular tube connecting the compression section and the anti - shedding section. The inner diameter of the connection section is the same as that of the drainage section, the transition section, and the compression section. The inner diameter of the top of the anti - shedding section is the same as that of the connecting tube, and it gradually changes to correspond to the maximum cross - sectional diameter of the anti - shedding structure of the anti - shedding and anti - skid guiding needle; the surface of the anti - shedding and anti - skid guiding needle has anti - skid grooves, and the end of the needle has an anti - shedding structure that is large at the top and small at the bottom and is stacked layer by layer. The anti - shedding structure is combined with the internal thread at the end of the anti - shedding section, thereby connecting the guiding needle and the drainage tube body into one body.

[0009] Furthermore, continuous imaging lines are arranged on the surface of the drainage tube body, which is convenient for medical staff to master the position of the drainage tube body during the puncture process; and printing points are arranged on the imaging lines of the compression section, which is convenient for further positioning of the compression section.

[0010] During specific use, the guiding needle is tightly combined with the anti - shedding structure at the end of the drainage tube body. Then, the guiding needle is used to puncture the skin and enter the patient's body. The position of the drainage tube is controlled according to imaging or ultrasound observation. After the drainage tube reaches the predetermined position, the guiding needle is punctured out of the patient's body along the preset path. At this time, the drainage tube body moves out of the body along with the guiding needle. After the guiding needle exits the body, hold the exposed part of the guiding needle, pull out the entire guiding needle, and continue to bring the drainage tube in until the drainage section enters the body. Observe the position of the imaging lines through imaging or ultrasound, and then determine the positions of the drainage section and the compression section of the drainage tube body to ensure that one - third to one - half of the compression section remains in the body and combine with the position of the printing points. At this time, a part of the drainage section, the transition section, and the compression section are all left in the patient's body, while the other parts of the drainage tube body are placed outside the patient's body. At this time, cut off the anti - shedding section and the guiding needle, and connect an external connection drainage device at the end of the connection section.

[0011] During the above process, due to the anti - shedding structure at the end of the anti - shedding and anti - skid guiding needle that is large at the top and small at the bottom and is stacked layer by layer, and the anti - shedding structure is combined with the internal thread at the end of the anti - shedding section, the connection between the two is more stable and will not fall off during the puncture process. And there are anti - skid grooves on the surface of the guiding needle, which is convenient for medical staff to hold.

[0012] The drainage tube with the above structure has a cross-shaped round tube with an outer groove in the drainage section, which can facilitate the drainage of exudate and infected fluid in the patient's body while avoiding blockage. The cross-section of the variable connection section is cross-shaped, which can play a certain supporting role and facilitate the passage of the drainage fluid. There is a strip-shaped convex support structure inside the compression section, which can play the role of a reinforcing rib. Even if this part is deformed under pressure, the above strip-shaped protrusion can form a flow channel inside the tube body to facilitate the discharge of the drainage fluid and will not be completely squeezed and deformed to cause blockage of the drainage tube. The subsequent connection section and anti-detachment section are located outside the patient's body, so there is no need to set a support structure inside; the above drainage tube can be directly prepared by an integral molding process, which reduces the production cost and has a high yield rate.

[0013] In summary, the drainage tube with the above structure is convenient to use and has a simple structure. The cross-shaped and strip-shaped support structures inside the tube body endow it with compressive function. The anti-detachment structure at the end of the guiding needle combined with the internal thread of the anti-detachment section can effectively prevent the drainage tube from falling off the needle tip during puncture. The anti-slip groove on the surface helps to solve the problem of easy slipping when operating the guiding needle while wearing gloves, reducing the operation difficulty during use.

Detailed implementation mode

[0024] The following is a further detailed description of the above content of the present utility model through specific implementation modes in the form of embodiments. All technologies implemented based on the above content of the present utility model fall within the scope of the present utility model.

[0025] As Figures 1-8 shown, the present utility model provides an anti-disconnection and anti-slip integrally formed pressure-resistant drainage tube, including a drainage tube body and an anti-disconnection and anti-slip guiding needle 08 sleeved at the end of the drainage tube. The diameter of the drainage tube body is uniform and consists of a drainage section 01, a variable connection section 02, a pressure-resistant section 03, a connection section 04, and an anti-disconnection section 05. The cross-sectional structures of the above five sections are different, and support structures are provided inside the drainage section 01, the variable connection section 02, and the pressure-resistant section 03. The anti-disconnection and anti-slip guiding needle 08 is sleeved on the anti-disconnection section 05.

[0026] Specifically, the drainage section 01 is a cross-shaped tube with an outer groove, and its rear side gradually changes into a variable connection section 02 with a cross-shaped cross-section; the rear end of the variable connection section 02 is connected to a pressure-resistant section 03, and a strip-shaped convex support structure is arranged inside it; the connection section 04 is a circular tube connecting the pressure-resistant section 03 and the anti-disconnection section 05. The inner diameter of the connection section is the same as that of the drainage section, the variable connection section, and the pressure-resistant section. The inner diameter of the top of the anti-disconnection section is the same as that of the connection tube and gradually changes to correspond to the maximum cross-sectional diameter of the anti-disconnection structure of the anti-disconnection and anti-slip guiding needle;

[0027] The surface of the anti-disconnection and anti-slip guiding needle 08 has an anti-slip groove 082, and the end of the needle has an anti-disconnection structure 081 that is large at the top and small at the bottom and is stacked layer by layer. The anti-disconnection structure 081 is combined with the internal thread at the end of the anti-disconnection section 05, thereby connecting the guiding needle and the drainage tube body into one body.

[0028] Furthermore, continuous developing lines 07 are arranged on the surface of the drainage tube body, which is convenient for medical staff to master the position of the drainage tube body during the puncture process; and printing points 06 are arranged on the developing line of the pressure-resistant section 03, which is convenient for further positioning of the pressure-resistant section.

[0029] During specific use, as Figure 9As shown, the guiding needle is tightly combined with the anti-detachment structure at the end of the drainage tube body. Then, the guiding needle is used to puncture the skin and enter the patient's body. According to imaging or ultrasonic observation, the position of the drainage tube is controlled. After the drainage tube reaches the predetermined position, the guiding needle is withdrawn from the patient's body along the preset path. At this time, the drainage tube body moves out of the body along with the guiding needle. After the guiding needle exits the body, hold the exposed part of the guiding needle, pull out the entire guiding needle, and continue to insert the drainage tube until the drainage section enters the body. Observe the position of the imaging line through imaging or ultrasonic, and then determine the positions of the drainage section and the drainage tube body of the compression-resistant section, ensuring that one-third to one-half of the compression-resistant section remains in the body in combination with the printing point position. At this time, a part of the drainage section, the transition section, and the compression-resistant section remains in the patient's body, while the other parts of the drainage tube body are placed outside the patient's body. At this time, cut off the anti-detachment section and the guiding needle, and connect the external connection drainage device at the end of the connection section.

[0030] In the above process, due to the anti-detachment structure with a gradually decreasing size from top to bottom and stacked layers at the end of the anti-detachment and anti-slip guiding needle, the anti-detachment structure is combined with the internal thread at the end of the anti-detachment section, and the connection between the two is more stable and will not fall off during the puncture process. There are anti-slip grooves on the surface of the guiding needle, which is convenient for medical staff to hold.

[0031] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the utility model.
