Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an infection protection device for cardiovascular interventional surgery. Background Technology

[0002] Cardiovascular interventional surgery is a novel technique for diagnosing and treating cardiovascular diseases. It involves inserting a cardiac catheter through a punctured blood vessel under continuous digital subtraction angiography. Specific cardiac catheterization techniques are then used to diagnose and treat heart disease. A catheter sheath is required in cardiovascular interventional surgery.

[0003] During use, the catheter sheath supports the guidewire and the vein. When inserting the guidewire into the blood vessel through the catheter sheath, the guidewire needs to be sterilized. Therefore, an infection protection device needs to be installed at one end of the catheter sheath. However, existing infection protection devices are usually relatively simple in structure, generally consisting of a sterilization pad and an insertion slot. Such infection protection devices have certain shortcomings during use. It is generally difficult to thoroughly sterilize the side surface of the tube inserted into the catheter sheath through the sterilization pad, thus reducing the sterilization effect of the tube. Secondly, the sterilization solution inside the sterilization pad is limited and is used up quickly after insertion into the tube, resulting in poor durability of the infection protection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-infection protection device for cardiovascular interventional surgery. It solves the problem that traditional anti-infection protection devices have a relatively simple structure and cannot fully disinfect the catheter during use. This improves the disinfection effect of the anti-infection protection device on the tubing inserted into the catheter sheath, and also avoids the situation where the disinfectant in the anti-infection protection device runs out during use, thus improving the durability of the anti-infection protection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an infection prevention and protection device for cardiovascular interventional surgery, comprising a catheter sheath and a protective seat. A first disinfection box is fixedly connected to the upper surface of the protective seat, and a support block is fixedly connected to the inner wall of the first disinfection box. A mounting frame is fixedly connected to one side surface of the support block, and a ball bearing is rotatably mounted on the inner side wall of the mounting frame. A disinfection ring is snapped onto the inner side of the mounting frame, and a disinfection cotton is wrapped on the outer surface of the disinfection ring. The disinfection cotton on the side surface of the disinfection ring contacts the ball bearing on the inner side wall of the mounting frame. A lid is provided at the upper end of the first disinfection box, and the lower end of the lid is threadedly connected to the first disinfection box. A second disinfection box is provided on the upper surface of the lid, and a drying mechanism is fixedly mounted at the lower end of the protective seat.

[0006] Preferably, the second disinfection box has an annular cotton pad inside, and a drainage cotton is fixedly connected to the lower surface of the annular cotton pad. The box cover has a through hole inside, and the drainage cotton passes through the through hole and contacts the side surface of the disinfection ring.

[0007] Preferably, the upper end of the second disinfection box is fastened with a cover plate, and the inside of the cover plate is fitted with a filling hole.

[0008] Preferably, the drying mechanism includes a cavity located inside the protective seat, and a heating wire is fixedly installed inside the cavity, with one end of the heating wire passing through the protective seat and fixedly connected to a temperature controller.

[0009] Preferably, a protective shell is fixedly fitted on the upper side surface of the catheter sheath, and a mounting base is fixedly connected to the upper end of the protective shell. A limiting groove is formed on the outer side surface of the mounting base, and a sealing groove is formed on the inner side surface of the mounting base.

[0010] Preferably, the lower end of the protective seat is fixedly connected to an installation head, and a rubber ring is fixedly connected to the outer surface of the installation head. The rubber ring corresponds to the sealing groove. A limiting plate is fixedly connected to the lower side surface of the protective seat, and the lower end of the limiting plate corresponds to the limiting groove.

[0011] This invention provides an infection protection device for cardiovascular interventional surgery. Compared with the prior art, it has the following advantages:

[0012] 1. The first disinfection box, which is fixedly installed on the upper end of the protective base, and the disinfection ring inside the first disinfection box, which is connected by a mounting bracket, are fixedly connected to the upper surface of the box cover. The annular cotton pad and drainage cotton installed inside the first disinfection box work together to solve the problem that the traditional anti-infection protection device has a relatively simple structure and cannot fully disinfect the catheter during use. This improves the disinfection effect of the anti-infection protection device on the tube inserted into the catheter sheath, and also avoids the situation where the disinfectant in the anti-infection protection device runs out during use, thus improving the durability of the anti-infection protection device.

[0013] 2. The cover plate, which is threaded to the inner surface of the second disinfection box and snapped to the upper end of the second disinfection box, allows the second disinfection box and the disinfection ring to be opened easily. This makes it convenient for doctors to replace the disinfection ring inside the mounting frame and the annular cotton pad inside the second disinfection box, and prevents cross-infection during subsequent use.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an infection prevention and protection device for cardiovascular interventional surgery, including a catheter sheath 1 and a protective seat 2. A first disinfection box 3 is fixedly connected to the upper surface of the protective seat 2, and a support block 301 is fixedly connected to the inner wall of the first disinfection box 3. A mounting frame 303 is fixedly connected to one side surface of the support block 301, and a ball bearing is rotatably installed on the inner side wall of the mounting frame 303. A disinfection ring 302 is snapped on the inner side of the mounting frame 303, and a disinfection cotton is covered on the outer surface of the disinfection ring 302. The disinfection cotton on the side surface of the disinfection ring 302 contacts the ball bearing on the inner side wall of the mounting frame 303. A box cover 4 is provided at the upper end of the first disinfection box 3, and the lower end of the box cover 4 is threadedly connected to the first disinfection box 3. A second disinfection box 406 is provided on the upper surface of the box cover 4. A drying mechanism is fixedly installed at the lower end of the protective seat 2.

[0022] As a technical optimization of this utility model, the second disinfection box 406 is provided with an annular cotton pad 405 inside, and a drainage cotton 401 is fixedly connected to the lower surface of the annular cotton pad 405. The box cover 4 has a through hole 402 inside, and the drainage cotton 401 passes through the through hole 402 and contacts the side surface of the disinfection ring 302. The annular cotton pad 405 inside 306 and the drainage cotton 401 on the lower surface of the annular cotton pad 405 can easily apply disinfectant to the side surface of the disinfection ring 302, thereby avoiding the disinfectant from running out during the tube insertion process. The upper end of the second disinfection box 406 is snapped with a cover plate 403, and the inside of the cover plate 403 is provided with a filling hole 404, which facilitates the filling of disinfectant into the second disinfection box 406.

[0023] As a technical optimization of this utility model, the drying mechanism includes a cavity 206, which is located inside the protective seat 2. A heating wire 205 is fixedly installed inside the cavity 206, and one end of the heating wire 205 passes through the protective seat 2 and is fixedly connected to a temperature controller 204. The drying mechanism can quickly evaporate the disinfectant on the side surface of the insertion tube, preventing the tube from bringing the disinfectant into the patient's body.

[0024] As a technical optimization of this utility model, a protective shell 102 is fixedly sleeved on the upper side surface of the catheter sheath 1, and a mounting base 103 is fixedly connected to the upper end of the protective shell 102. A limiting groove 1031 is opened on the outer side surface of the mounting base 103, and a sealing groove 1032 is opened on the inner side surface of the mounting base 103.

[0025] As a technical optimization of this utility model, the lower end of the protective seat 2 is fixedly connected to the mounting head 202, and the outer surface of the mounting head 202 is fixedly connected to the rubber ring 203, which corresponds to the sealing groove 1032. The lower side surface of the protective seat 2 is fixedly connected to the limiting plate 201, and the lower end of the limiting plate 201 corresponds to the limiting groove 1031. The sealing groove 1032 and the rubber ring 203 can improve the connection sealing between the protective seat 2 and the catheter sheath 1. The limiting plate 201 and the limiting groove 1031 cooperate with each other to improve the connection stability between the protective seat 2 and the catheter sheath 1. Therefore, the protective seat 2 may rotate during the insertion process, which may affect the doctor's operation.

[0026] In use, this invention first aligns the mounting head 202 at the lower end of the protective base 2 with the mounting base 103, and simultaneously aligns the limiting plate 201 with the limiting groove 1031. Then, the protective base 2 is inserted into the mounting base 103 via the mounting head 202. Next, disinfectant is added into the second disinfection box 406 through the filling hole 404. The disinfectant is then guided into the disinfection ring 302 through the annular cotton pad 405 and the drainage cotton 401. Afterward, the doctor inserts the catheter sheath 1 into the patient's body. Then, the doctor passes one end of the catheter through the second disinfection box 406, the box cover 4, and the first disinfection box 3. The catheter passes through the inside of the protective seat 2 and then enters the patient's body through the catheter sheath 1. When the catheter passes through the inside of the first disinfection box 3, the side surface of the catheter will be squeezed against the side surface of the disinfection ring 302. At this time, the catheter can drive the disinfection ring 302 to rotate inside the mounting frame 303. The disinfection cotton on the side surface of the disinfection ring 302 will apply disinfectant to the side surface of the catheter for disinfection. When the catheter passes through the inside of the protective seat 2, the temperature controller 204 activates the heating wire 205 to heat the inside of the cavity 206. At this time, the heat is transferred to the side surface of the tube through the protective seat 2, thereby drying and evaporating the disinfectant.
