Description

Technical Field

[0001] This utility model relates to the field of medical drainage technology, and more specifically, to a drainage device for postoperative wound care in urology. Background Technology

[0002] Currently, urology is a branch of medicine that specializes in the study of the male and female urinary tracts and the male reproductive system. It mainly originated from a sub-specialty of surgery. Regardless of gender, the urinary tract and reproductive tract are closely related, and diseases of the two often affect each other. Drainage is a surgical treatment method that is a technique to drain pus, blood, or other fluids accumulated between tissues or in body cavities from the outside or into the internal organs. Surgical drainage not only includes external drainage, such as abscess incision, enterostomy, abdominal drainage, and thoracic drainage, but also internal drainage, which involves diverting or shunting the fluid to another hollow organ to achieve the purpose of drainage.

[0003] In the existing technology, when the reservoir is full, it is inconvenient to quickly separate it from the tubing. At the same time, the separated end of the reservoir and tubing cannot be sealed, which can easily lead to bacterial infection and leakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drainage device for postoperative wound care in urology, which aims to improve the problems of inconvenience in quickly separating the catheter and the inability to seal the end of the reservoir and catheter after separation, which can easily lead to bacterial infection and leakage.

[0005] This utility model is implemented as follows: A drainage device for postoperative wound care in urology includes a reservoir, a conversion ring, and a cannula. The conversion ring is threaded onto the top of the reservoir and is internally connected. A first support ring is fixedly installed on the top of the inner wall of the conversion ring. Multiple first elastic telescopic rods are fixedly installed on the bottom of the first support ring. A first sealing plate is fixedly installed on the bottom of the first elastic telescopic rod. The first sealing plate is slidably connected to the inner wall of the conversion ring and has a top rod fixedly installed on its top. The cannula is sleeved on the top of the conversion ring. A horizontal plate is fixedly installed on the inner wall of the cannula. A second elastic telescopic rod is fixedly installed on the bottom of the horizontal plate. A second sealing plate is fixedly installed on the bottom of the second elastic telescopic rod. A sealing ring that cooperates with the second sealing plate is provided on the bottom of the inner wall of the cannula. The second sealing plate abuts against the top rod. Multiple round holes are provided on the bottom of the side wall of the cannula. A drainage component is installed on the top of the cannula.

[0006] In a preferred embodiment of this utility model, the drainage assembly includes a drainage bucket, a drainage tube, and a drainage needle tube. The drainage bucket is fixedly installed at the top of the insertion tube, the drainage tube is fixedly installed at the top of the drainage bucket, and the drainage needle tube is fixedly installed at the top of the drainage tube. The drainage bucket is made of transparent material.

[0007] In a preferred embodiment of this utility model, an observation window is provided on one side of the liquid storage box, and a scale is provided on the observation window.

[0008] In a preferred embodiment of this utility model, the outer side of the conversion ring is symmetrically provided with threads, and the top of the liquid storage box is provided with a threaded hole that matches the outer thread of the conversion ring.

[0009] In a preferred embodiment of this utility model, the first elastic telescopic rod and the second elastic telescopic rod have the same structure, consisting of a pull rod and a sleeve rod. One end of the sleeve rod is slidably sleeved onto the pull rod, and a spring is fixedly installed between the pull rod and the inner wall of the sleeve rod. Limiting blocks are symmetrically fixedly installed on the outer side of the pull rod, and a limiting groove matching the limiting block is provided on the inner wall of the sleeve rod. The limiting block is slidably connected to the inner wall of the limiting groove.

[0010] In a preferred embodiment of this utility model, a limiting plate is fixedly installed between the two sides of the inner wall of the liquid storage box, and a gap is provided between the top of the limiting plate and the top of the inner wall of the liquid storage box. The first sealing plate is moved to fit against the top of the limiting plate.

[0011] In a preferred embodiment of this utility model, a sealing cover is rotatably installed on the outside of the insertion tube. The bottom end of the sealing cover is threadedly connected to the top end of the outer side of the conversion ring. After the sealing cover is fully threadedly connected to the conversion ring, the first sealing plate separates from the inner wall of the conversion ring, and at the same time, the second sealing plate separates from the sealing ring.

[0012] In a preferred embodiment of this utility model, a positioning ring is fixedly installed on the outer side of the conversion ring, and an annular groove matching the positioning ring is provided inside the sealing cover, with the positioning ring slidably connected to the inner wall of the annular groove.

[0013] The beneficial effects of this utility model are:

[0014] For easy disassembly and sealing, preventing bacterial infection and leakage: The reservoir and tubing are connected by a conversion ring, which is threaded onto the reservoir. A sealing cap is rotated onto the outside of the tubing and threaded onto the conversion ring. When the liquid in the reservoir needs to be poured out, the sealing cap is rotated to separate from the conversion ring, and the tubing is pulled out. At this time, the first and second elastic telescopic rods drive the first and second sealing plates to move back and seal, avoiding bacterial infection and leakage problems caused by one end not being able to seal after disassembly. It is convenient and quick.

[0015] Facilitates observation of fluid storage: An observation window with a scale is provided on one side of the fluid storage box. Medical staff can visually understand the amount of fluid in the storage box through the observation window, and promptly grasp the drainage status of the patient's postoperative wound in order to make appropriate medical decisions.

[0016] The connection is secure and easy to operate: symmetrical threads are provided on the outer side of the conversion ring, matching the threaded hole at the top of the reservoir, ensuring a secure connection. When the sealing cap is threadedly connected to the conversion ring, the positioning ring on the outer side of the conversion ring slides into the annular groove inside the sealing cap, ensuring both the stability of the sealing cap's rotational installation and ease of operation for medical personnel.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a drainage device for postoperative wound care in urology, comprising a reservoir 110, a conversion ring 120, and an insertion tube 130. The conversion ring 120 is threaded onto the top of the reservoir 110 and is internally connected. A first support ring 121 is fixedly installed on the top of the inner wall of the conversion ring 120. Multiple first elastic telescopic rods 122 are fixedly installed on the bottom of the first support ring 121. A first sealing plate 123 is fixedly installed on the bottom of the first elastic telescopic rods 122. The first sealing plate 123 is slidably connected to the inner wall of the conversion ring 120 and has a top rod 124 fixedly installed on its top. The insertion tube 130 is sleeved onto the top of the conversion ring 120. A horizontal plate 131 is fixedly installed on the inner wall of the insertion tube 130. A second elastic telescopic rod 132 is fixedly installed on the bottom of the horizontal plate 131. The bottom of the second elastic telescopic rod 132 is fixedly installed... A second sealing plate 133 is installed. A sealing ring 134 that mates with the second sealing plate 133 is provided at the bottom of the inner wall of the insertion tube 130. The second sealing plate 133 abuts against the top rod 124. Multiple round holes are provided at the bottom of the side wall of the insertion tube 130. A limiting plate 125 is fixedly installed between the two sides of the inner wall of the liquid storage box 110. A gap is provided between the top of the limiting plate 125 and the top of the inner wall of the liquid storage box 110. The first sealing plate 123 is moved to fit against the top of the limiting plate 125. A drainage assembly is installed at the top of the insertion tube 130. The drainage assembly includes a drainage bucket 140, a drainage tube 141 and a drainage needle. The drainage bucket 140 is fixedly installed at the top of the insertion tube 130. The drainage tube 141 is fixedly installed at the top of the drainage bucket 140. The drainage needle is fixedly installed at the top of the drainage tube 141. The drainage bucket 140 is made of transparent material.

[0027] In some specific implementation schemes, an observation window with a scale is provided on one side of the fluid reservoir 110. Medical staff can directly observe the amount of fluid inside the reservoir 110 through the observation window without opening it, and can accurately read the fluid volume using the scale. This helps medical staff to promptly monitor the accumulation of drainage fluid, assess the patient's postoperative recovery status, and, if the drainage fluid volume continues to increase or decrease abnormally, can serve as one of the bases for judging changes in the patient's condition, thereby adjusting the treatment plan.

[0028] In some specific implementations, the adapter ring 120 has symmetrically arranged threads on its outer side, and the top of the reservoir 110 has a threaded hole that matches the threads on the outer side of the adapter ring 120. This threaded connection method makes the installation and removal of the adapter ring 120 and the reservoir 110 convenient, and the connection is tight and secure. In practical use, it facilitates the replacement of the reservoir 110 by medical staff, and the symmetrical thread design makes the force more even, enhances the stability of the connection, and reduces the risk of leakage.

[0029] In some specific implementations, the first elastic telescopic rod 122 and the second elastic telescopic rod 132 have the same structure, consisting of a pull rod and a sleeve rod. One end of the sleeve rod is slidably connected to the pull rod, and a spring is fixedly installed between the pull rod and the inner wall of the sleeve rod. A limiting block is symmetrically fixedly installed on the outer side of the pull rod, and a limiting groove matching the limiting block is provided on the inner wall of the sleeve rod. The limiting block and the limiting groove are slidably connected. The design of the limiting block and the limiting groove restricts the range of movement of the pull rod within the sleeve rod, preventing the pull rod from dislodging from the sleeve rod, ensuring the stability and reliability of the elastic telescopic rod structure, and thus ensuring the normal operation of the entire device.

[0030] Please see Figure 6 The sealing cover 135 is rotated and installed on the outside of the insertion tube 130. The bottom end of the sealing cover 135 is threadedly connected to the top end of the outer side of the conversion ring 120. After the sealing cover 135 is fully threadedly connected to the conversion ring 120, the first sealing plate 123 separates from the inner wall of the conversion ring 120, and at the same time, the second sealing plate 133 and the sealing ring 134 separate.

[0031] In some specific implementations, a positioning ring 136 is fixedly installed on the outer side of the conversion ring 120, and an annular groove matching the positioning ring 136 is provided inside the sealing cover 135. The positioning ring 136 is slidably connected to the inner wall of the annular groove. The positioning ring 136 and the annular groove cooperate with each other to play a positioning and guiding role during the rotation of the sealing cover 135, making the installation of the sealing cover 135 more accurate and smooth, avoiding the sealing cover 135 from shifting or jamming during rotation, and further enhancing the stability and sealing of the device connection.

[0032] Working principle: Before use, install the conversion ring 120 threaded onto the reservoir 110, then insert the cannula 130 into the top of the conversion ring 120 and fix it with the sealing cap 135 threaded. At the same time, the top rod 124 and the second sealing plate 133 come into contact and move, causing the first elastic telescopic rod 122 to stretch and the second elastic telescopic rod 132 to contract. This causes the second sealing plate 133 to move upward and disengage from the sealing ring 134, and the first sealing plate 123 to move downward and disengage from the conversion ring 120. Finally, insert the drainage needle into the patient's body. When the liquid in the reservoir 110 needs to be poured out, simply rotate the sealing cap 135 to separate it from the conversion ring 120 and then pull out the cannula 130. At this time, the first elastic telescopic rod 122 and the second elastic telescopic rod 132 drive the first sealing plate 123 and the second sealing plate 133 to move back and seal.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
