Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a sterilization device for locking tibia installation. Background Technology

[0002] The tibia is an important bone in the lower leg, located on the medial side. It is the main weight-bearing bone of the lower leg and, together with the fibula on the lateral side, forms the skeletal structure of the lower leg. In orthopedic surgery, tibial fractures often require the use of tibial locking techniques. However, postoperative pin tract infection is a common and serious problem. According to relevant studies, the incidence of pin tract infection after external fixation is between 4% and 45%. Once infection occurs, it will not only prolong the patient's recovery time, increase the patient's pain and financial burden, but in severe cases, it may also lead to complications such as osteomyelitis, affecting fracture healing and even requiring a second surgery.

[0003] Currently, in clinical practice, disinfection of sites such as tibial external fixator pinholes mainly relies on manual operation by medical staff. Specifically, medical staff need to use tweezers to pick up cotton balls soaked in disinfectant and carefully wipe the pinhole and surrounding skin. This traditional disinfection method has many drawbacks. On the one hand, the frequency of manual operation is usually 1-2 times a day. For some patients with high infection risk, the frequency of disinfection may need to be increased, which undoubtedly greatly increases the workload of medical staff. In the orthopedic wards of some large hospitals, a large number of tibial fracture patients need to be cared for every day. Medical staff often need to spend a lot of time and energy on the heavy disinfection work. On the other hand, due to the complex condition of the skin around the pinhole, manual wiping is difficult to ensure the uniformity and comprehensiveness of disinfection, which can easily lead to disinfection dead spots and create conditions for bacterial growth.

[0004] Therefore, a sterilization device for locking the tibia is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a disinfection device for locking tibial installation, which has the advantages of solving the problems of poor disinfection effect, increased workload of medical staff, and inability to adjust the disinfection plan in real time in existing disinfection methods for tibial external fixation pinholes and other parts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5 As shown, this utility model provides a disinfection device for locking tibia installation, including a sleeve 1, on which a disinfectant spraying component 2 is installed; The disinfectant spraying assembly 2 includes an arc-shaped flexible tube 201 mounted on a sleeve 1. Adjacent arc-shaped flexible tubes 201 are connected by a connecting pipe 202. The arc-shaped flexible tube 201 is connected to a universal tube 203. One end of the universal tube 203 passes through the sleeve 1 and is connected to a nozzle 204. The nozzles 204 are evenly distributed on the inner wall of the sleeve 1. One of the arc-shaped flexible tubes 201 is connected to a liquid pump 205 through a pipe. The inlet of the liquid pump 205 is connected to a disinfectant storage tank 206 through a pipe. When the patient's lower leg is placed inside the sleeve 1, disinfectant is sprayed onto the lower leg. Compared with manual wiping or spraying, it can more quickly and comprehensively disinfect the lower leg, including the needle hole area, saving medical staff's operation time and energy, improving the efficiency of disinfection work. In the relatively closed sleeve space, it can ensure that the disinfectant evenly covers all parts of the lower leg, including the needle hole of the external fixator and the surrounding skin, reducing disinfection dead corners and minimizing the risk of infection.

[0017] Specifically, the sleeve 1 includes a first arc-shaped plate 101 and a second arc-shaped plate 102 arranged correspondingly at the top and bottom. The first arc-shaped plate 101 is connected to the second arc-shaped plate 102 through a connecting shaft 103. A first side ear 104 and a second side ear 105 are respectively fixedly connected to the side of the first arc-shaped plate 101 and the second arc-shaped plate 102 away from the connecting shaft 103. The first side ear 104 and the second side ear 105 are connected by a fixing bolt 106. By setting an openable sleeve 1 structure, the sleeve 1 can be divided into two arc-shaped plate structures, which facilitates the cleaning of the inner wall of the sleeve 1, avoids the growth of bacteria due to the difficulty in cleaning the inside of the sleeve 1, and is beneficial to the use of the disinfection device.

[0018] Furthermore, the second arc-shaped plate 102 is connected to the base 4 via the support frame 3. The liquid pump 205 and the disinfectant storage tank 206 are both located inside the base 4 to support the sleeve 1.

[0019] Furthermore, a liquid collection tank 5 is provided inside the base 4, and a liquid guide pipe 6 is connected to the top of the liquid collection tank 5. The liquid guide pipe 6 is connected to a liquid guide port 7, which is located on the second arc plate 102 to drain excess disinfectant.

[0020] It is worth noting that a drain port 8 is provided on one side of the collection tank 5 near the bottom for draining the disinfectant in the collection tank 5, and an injection port 9 is provided on one side of the disinfectant storage tank 206 near the top for adding disinfectant.

[0021] It is worth noting that arc-shaped baffles 10 are provided at both ends of the inner walls of the first arc plate 101 and the second arc plate 102. These baffles are used to prevent the disinfectant that falls on the inner wall of the bottom of the sleeve 1 from flowing out from both ends, and can also be used as support for the patient's lower leg.

[0022] The liquid pump 205 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0023] Working principle and process: After determining the position of the device, insert the patient's lower leg into the sleeve 1. If it is inconvenient to insert, the first arc plate 101 and the second arc plate 102 can be separated, and the lower leg can be placed on the first arc plate 101. Then, the first arc plate 101 and the second arc plate 102 can be connected. The spray angle of the nozzle 204 can be adjusted through the universal tube 203 so that the nozzle 204 can spray towards the needle hole position. Start the liquid pump 205 of the disinfectant spraying component 2. The disinfectant in the disinfectant storage tank 206 is sprayed out by the nozzle 204 after passing through the liquid pump 205, the connecting pipe 202, the arc hose 201, and the universal tube 203. Manual wiping or spraying allows for faster and more comprehensive disinfection of the lower leg, including the needle puncture site, saving medical staff time and effort and improving the efficiency of disinfection. Within the relatively enclosed sleeve space, it ensures that the disinfectant evenly covers all parts of the lower leg, including the needle puncture site of the external fixator and the surrounding skin, reducing disinfection dead spots and minimizing the risk of infection. Excess disinfectant is collected in the collection tank 5 through the inlet 7 and the tube 6. The openable sleeve 1 structure can divide the sleeve 1 into two arc-shaped plate structures to facilitate cleaning of the inner wall of the sleeve 1, preventing bacteria growth due to difficulty in cleaning the inside of the sleeve 1, and facilitating the use of the disinfection device.
