Description

Technical Field

[0001] This utility model relates to the field of medical drainage bag technology, specifically an anti-backflow medical drainage bag. Background Technology

[0002] A drainage bag generally refers to a transparent plastic bag attached to the end of a tube after surgery to drain blood or fluid from deep within the body or a surgical site. Commonly used drainage bags are disposable. They are made of medical-grade polymer materials and packaged in low-pressure PE bags. However, existing drainage bags have certain shortcomings.

[0003] For example, a multifunctional medical drainage bag with anti-backflow function, as described in application number CN202121891863.4, includes a drainage bag, a three-way tube, a spare bag, a sensor alarm device, a float valve, a hanging rod, a protective cover, a drain hole, and a hanging strap. The three-way tube connects the drainage bag and the spare bag. The sensor alarm device is installed on the three-way tube connected to the spare bag. The float valve is located inside the drainage bag and connected to the opening of the three-way tube inserted into the drainage bag. The hanging rod passes through the drainage bag plug and connects to the float valve, allowing the float valve to suspend inside the drainage bag. The protective cover is located inside the drainage bag and covers the outer end of the float valve. The drain hole is located at the bottom of the drainage bag and the spare bag. The hanging strap is located on the surface of the drainage bag. Advantages: The float valve can automatically close when the liquid in the bag reaches a certain amount, preventing liquid from entering the drainage bag. Excess liquid enters the spare bag. When liquid enters the spare bag, it triggers the sensor device and sounds an alarm. By removing the pin and changing the depth of the hanging rod inserted into the bag, the amount of liquid entering the drainage bag can be adjusted. However, the drainage bag has poor fixation effect and is prone to collision, scratching and wear with other materials. In addition, medical staff may not be able to detect excessive fluid volume in time, and the drainage bag is prone to overload. Furthermore, the drainage tube is prone to knotting during use, which can prevent the fluid from flowing smoothly.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed a medical drainage bag for preventing backflow. Utility Model Content

[0005] The purpose of this invention is to provide an anti-backflow medical drainage bag to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a medical drainage bag for preventing backflow, comprising a drainage bag body and a protective mechanism. The protective mechanism is fixedly connected to one side of the drainage bag body, and the protective mechanism includes a protective frame fixedly connected to the outer surface of the drainage bag body. A fixing block is fixedly connected to one side of the protective frame, and a rotating shaft is rotatably connected to the inner surface of the fixing block. An adsorption plate is fixedly connected to one side of the rotating shaft, and a load-reducing mechanism is fixedly connected to one side of the drainage bag body.

[0007] Preferably, the load-reducing mechanism includes a guide tube fixedly connected to one side of the main body of the drainage bag, and a diversion box is fixedly connected to the top of the guide tube, and a diversion tube is fixedly connected to the bottom of the diversion box.

[0008] Preferably, an anti-backflow valve is fixedly connected inside the main body of the drainage bag, and an infusion tube is fixedly connected to one end of the anti-backflow valve.

[0009] Preferably, the outer surface of the infusion tube is provided with a cross-shaped drain valve, and the bottom of the infusion tube is fixedly connected to a drain pipe.

[0010] Preferably, the outer surface of the drainage bag body is fixedly connected with scale lines, and the outer surface of the drainage bag body is fixedly connected with a hanging rope.

[0011] Preferably, a drainage tube is fixedly connected to the top of the drainage bag body, and a pagoda head is fixedly connected to one end of the drainage tube.

[0012] Preferably, a support frame is fixedly connected to the top of the protective frame, and a winding device is rotatably connected to one end of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model adds a protective frame to the outer surface of the drainage bag body through the setting of a protective mechanism, so as to avoid the drainage bag body from colliding with other materials and being squeezed and damaged, and to reduce the possibility of sharp objects puncturing the drainage bag. The direction of the rotating shaft can be changed as needed, and the drainage bag can be fixed in a suitable position through the suction plate to prevent people from rubbing against the drainage bag when walking, pulling the drainage bag, and easily causing discomfort to the patient.

[0015] 2. This utility model solves the problem of the burden-reducing mechanism by setting up a pressure-reducing mechanism. When the liquid inside the drainage bag exceeds the prohibition line, medical staff may not be able to detect it in time. The excess liquid will enter the diversion box through the guide tube, avoiding overloading of the drainage bag and reducing the burden on medical staff when there are many patients.

[0016] 3. This utility model uses a winding device on one side of the support frame to neatly wind up the drainage tube. Since the drainage tube is long, if it gets knotted or compressed, the liquid cannot flow smoothly. Winding up the excess drainage tube into the winding device can prevent this from happening.

[0022] 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.

[0023] like Figures 1-2 As shown, an anti-reflux medical drainage bag includes a drainage bag body 1 and a protective mechanism 2. The protective mechanism 2 is fixedly connected to one side of the drainage bag body 1. The protective mechanism 2 includes a protective frame 201 fixedly connected to the outer surface of the drainage bag body 1. A fixing block 202 is fixedly connected to one side of the protective frame 201. A rotating shaft 203 is rotatably connected to the inner surface of the fixing block 202. An adsorption plate 204 is fixedly connected to one side of the rotating shaft 203. A load-reducing mechanism 3 is fixedly connected to one side of the drainage bag body 1. The drainage bag body 1 is a sterile drainage bag made of transparent silicone, which is non-toxic and heat-resistant. The protective frame 201 is made of hard material and is lightweight. The rotating shaft 203 can adjust the angle of the adsorption plate 204, making it easy to use in different environments and reinforcing the drainage bag body 1.

[0024] like Figures 3-4 As shown, the burden reduction mechanism 3 includes a guide tube 301 fixedly connected to one side of the drainage bag body 1, and a diversion box 302 fixedly connected to the top of the guide tube 301, and a diversion tube 303 fixedly connected to the bottom of the diversion box 302. The inner surfaces of the guide tube 301, the infusion tube 5 and the drainage tube 7 are coated with graphene composite coating, which has the characteristics of environmental protection and sustainability.

[0025] Furthermore, an anti-backflow valve 4 is fixedly connected inside the main body 1 of the drainage bag, and an infusion tube 5 is fixedly connected to one end of the anti-backflow valve 4. A cross-shaped drain valve 6 is provided on the outer surface of the infusion tube 5, and a drain tube 7 is fixedly connected to the bottom of the infusion tube 5. The anti-backflow valve 4 has electrostatic adsorption force and plastic recovery force. It can only be opened when the drainage liquid flows in the forward direction and the forward pressure is greater than the electrostatic adsorption force and plastic recovery force. Even when the drainage bag is placed horizontally or upside down, it can effectively prevent the backflow of body fluid in the drainage bag and reduce the possibility of retrograde contamination. The cross-shaped drain valve 6 can be opened with one hand, which is convenient to operate.

[0026] Furthermore, a scale line 8 is fixedly connected to the outer surface of the drainage bag body 1, and a hanging rope 9 is fixedly connected to the outer surface of the drainage bag body 1. A drainage tube 10 is fixedly connected to the top of the drainage bag body 1, and a pagoda head 11 is fixedly connected to one end of the drainage tube 10. A biodegradable antibacterial filter membrane is provided on the inner surface of the drainage tube 10, which has a certain antibacterial effect. The scale line 8 can quickly determine the volume of liquid inside the drainage bag body 1. The hanging rope 9 makes it easy to fix the top of the drainage bag body 1. The pagoda head 11 is suitable for most urinary catheters.

[0027] Furthermore, a support frame 12 is fixedly connected to the top of the protective frame 201, and a winder 13 is rotatably connected to one end of the support frame 12. The support frame 12 supports the winder 13, and an anti-slip layer is provided on the contact surface between the winder 13 and the drainage tube 10 to prevent the drainage tube 10 from slipping.

[0028] Working principle: When using this anti-backflow medical drainage bag, first find a suitable position and rotate the rotating shaft 203 inside the fixing block 202 of the protective mechanism 2 to a suitable angle. Then, fix the protective frame 201 in the appropriate position using the suction plate 204. Next, connect the pagoda head 11 at the top of the drainage tube 10 to the urinary catheter. The longer drainage tube 10 is wound around the inside of the retractor 13 on one side of the support frame 12. Liquid enters the body 1 of the drainage bag through the drainage tube 10. When the internal liquid level exceeds the scale line... When the warning line 8 is reached, open the cross drain valve 6 on the outer surface of the infusion tube 5. Then, the liquid flows into the infusion tube 5 through the anti-backflow valve 4. If the medical staff fails to detect excessive liquid in time, the liquid inside the drainage bag body 1 enters the diversion box 302 through the guide tube 301 of the load reduction mechanism 3. Finally, open the cross drain valve 6 on the outside of the diversion tube 303 so that the liquid inside the drainage bag body 1 and the diversion box 302 are discharged through the drain tube 7. This is the working principle of the anti-backflow medical drainage bag.
