Description

Technical Field

[0001] The present invention belongs to the technical field related to medical supplies, and specifically discloses a self-controlled precision metering anti-backflow drainage bag. Background Art

[0002] Drainage bags are mainly used to collect urine from patients or as wound drainage after surgery. The urine excreted by the human body can show various physiological conditions. If the urine information in the drainage bag can be effectively recorded, it will be of great help for doctors to judge the patient's condition; Existing drainage bags cannot be well set on the hospital bed. Generally, they are placed on the hospital bed or hung on the hospital bed through external tools, and need to be removed when the patient gets out of bed and walks, which is rather troublesome. Moreover, the liquid in the drainage bag cannot be discharged in time according to the storage volume, resulting in great limitations in the use of the drainage bag. Therefore, we need to improve it. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems existing in the background art, and a self-controlled precision metering anti-backflow drainage bag is proposed, including a bag body. An automatic control warning member is arranged inside the bag body. An intervention tube is connected and installed above the interior of the bag body. One end of the intervention tube away from the bag body is connected and installed with a catheter. A drainage member is connected and arranged on one side below the interior of the bag body. A backflow valve is arranged in the middle of the intervention tube. A fitting member is arranged at the rear end of the bag body. A hanging member is arranged at the upper part of the bag body and near the rear end of the intervention tube.

[0004] Preferably, the automatic control warning member includes a clamping strip arranged above the interior of the bag body. Both ends inside the clamping strip are connected and provided with clamping tubes. Floating members are arranged inside both clamping tubes.

[0005] Preferably, the floating member includes a floating plate slidably installed inside the clamping tube. A resisting rod is fixedly arranged above the floating plate. The resisting rod is arranged in an L shape and its end is connected with a resisting ball.

[0006] Preferably, the drainage member includes a drainage pipe connected and installed on one side below the interior of the bag body. A spherical ring cavity is connected and installed below the interior of the drainage pipe. A sealing extrusion rod slides below the interior of the spherical ring cavity. An outlet pipe is connected and installed on one side inside the spherical ring cavity.

[0007] Preferably, the hanging member includes a hanging ring fixedly arranged at the upper part of the bag body and close to the rear end of the intervention tube. Connecting rods are arranged on both outer sides of the hanging ring. Connecting seats are arranged at the ends of the two connecting rods away from each other. The connecting seats are fixedly connected to the bag body. An L-shaped sliding frame is rotatably installed inside the connecting seat. A clamping rod is slidably installed at the rear end inside the L-shaped sliding frame. A plurality of magnetic attraction buttons are installed on the inner surface of the end of the clamping rod away from the L-shaped sliding frame. Hanging ropes are arranged at the lower ends of the two clamping rods. Rewinders are arranged at the lower ends of the two hanging ropes. Elastic clamps are arranged on the outer walls of the two clamping rods on the side away from the magnetic attraction buttons.

[0008] Preferably, a first rewinding elastic band and a second rewinding elastic band are respectively arranged on the outer sides of the two rewinders. A clamping button is arranged on the outer side of the first rewinding elastic band. A clamping groove is arranged on the outer side of the second rewinding elastic band.

[0009] Preferably, the fitting member includes card shells respectively arranged on the outer side of the rear end of the bag body. Buffer members are arranged inside the two groups of card shells.

[0010] Preferably, the buffer member includes an air bag. The air bag is located inside the card shell. An arc-shaped pressing plate is arranged on the outer side of the card shell. Two groups of buzzers are arranged on the inner wall of the pressing plate. A pressure sensor is arranged at the upper part of the air bag. A liquid level mark is arranged on the outer side of the front end of the bag body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By arranging a card strip, a card tube, a floating plate, a resisting rod, and a resisting ball inside the bag body, when the liquid volume inside the bag body exceeds the card tube, the liquid level and air pressure inside the bag body will cause the floating plate and the resisting rod to move upward. The resisting ball can then move upward to contact the inner rear wall of the bag body until it presses against the air bag. The air pressure inside the air bag changes when it is squeezed. Through the arranged pressure sensor, the buzzer makes a sound, warning the surrounding caregivers and patients at this time, reminding medical staff or patients to drain the liquid in time to avoid liquid overflow.

[0012] 2. By arranging the L-shaped sliding frame and the clamping rod, the bag body can be clamped on one side of the hospital bed and hung on the edge of the hospital bed. Compared with the conventional random placement on the hospital bed, it is safer and there will be no situation such as side leakage. Moreover, the hanging ring and the elastic clamp can be cooperatively hung outside the guardrail of the hospital bed, which is very convenient to use. Both clamping and disassembly are relatively convenient.

[0013] 3. By arranging the hanging ropes, the rewinder, the first rewinding elastic band, the second rewinding elastic band, the clamping button, and the clamping groove, it can meet the need for the patient to tie the bag body to the leg during the movement process, thereby reducing the pressure on the patient and facilitating the patient to walk.

DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-7 The self-controlled precision metering anti-backflow drainage bag shown in the figure includes a bag body 1, an automatic warning part is arranged inside the bag body 1, an intervention tube 20 is installed on the upper part of the bag body 1, and a catheter 4 is installed on the end of the intervention tube 20 away from the bag body 1, a drainage part is installed on the lower side of the bag body 1, a backflow valve 10 is arranged in the middle of the intervention tube 20, a fitting part is arranged at the rear end of the bag body 1, and a hanging part is arranged on the upper part of the bag body 1 and close to the rear end of the intervention tube 20, the intervention tube 20 is connected to the catheter 4, and the catheter 4 is connected to the drainage part to guide the liquid into the bag body 1, and the backflow of the liquid can be prevented by the backflow valve 10.

[0019] The self - control warning component includes a clamping strip 22 arranged above the interior of the bag body 1. At both ends inside the clamping strip 22, there are clamping tubes 23 communicated. Inside both clamping tubes 23, there are floating components.

[0020] The floating component includes a floating plate 18 slidably installed inside the clamping tube 23. Above the floating plate 18, there is a resisting rod 19 fixedly arranged. The resisting rod 19 is arranged in an L - shape and its end is connected with a resisting ball 21. When the liquid volume in the bag body 1 exceeds the area of the clamping strip 22 and overflows from the clamping tube 23, at this time, the floating plate 18 and the resisting rod 19 at the clamping tube 23 will move upward at the clamping tube 23 under the push of the air pressure and the liquid level inside the bag body 1, causing the resisting ball 21 at the end of the resisting rod 19 to fit against the airbag 31. After the inside of the airbag 31 is squeezed, the gas volume decreases and the air pressure increases. Therefore, the liquid can be discharged automatically in this way.

[0021] The drainage component includes a drainage pipe 3 communicated and installed at one side below the interior of the bag body 1. Below the interior of the drainage pipe 3, there is a spherical ring cavity 7 communicated and installed. Inside the spherical ring cavity 7 below, there is a sealing extrusion rod 6 slidably installed. On one side inside the spherical ring cavity 7, there is an outlet pipe 8 communicated and installed. The sealing extrusion rod 6 is made of rubber material. When closing the drainage pipe 3, only need to pull out the sealing extrusion rod 6 forcefully. At this time, the liquid flows into the spherical ring cavity 7 and then is discharged from the inclined outlet pipe 8 on one side. The purpose is to avoid the liquid flowing onto the hand during drainage, ensuring the safety and hygiene of drainage.

[0022] The hanging component includes a hanging ring 5 fixedly arranged on the upper part of the bag body 1 and near the rear end of the access tube 20. On both outer sides of the hanging ring 5, there are connecting rods 25. At the mutually - far - away ends of the two connecting rods 25, there are connecting seats 12. The connecting seats 12 are fixedly connected with the bag body 1. Inside the connecting seats 12, there is an L - shaped sliding frame 9 rotatably installed. Inside the rear end of the L - shaped sliding frame 9, there is a clamping rod 11 slidably installed. On the inner surface of the end of the clamping rod 11 far away from the L - shaped sliding frame 9, there are a plurality of magnetic attraction buttons 29 installed. At the lower ends of the two clamping rods 11, there are hanging ropes 13. At the lower ends of the two hanging ropes 13, there are winding devices 14. On the outer walls of the sides of the two clamping rods 11 far away from the magnetic attraction buttons 29, there are elastic clamps 17. The hanging ring 5 can be hung on the hospital bed at will. By pulling out the clamping rod 11, the L - shaped sliding frame 9 is clamped against the side frame of the hospital bed, and the bag body 1 can be more firmly installed on the hospital bed. It can be hung in various ways according to different specifications of the hospital bed. The clamping rod 11 and the L - shaped sliding frame 9 can be used for drainage of patients who are bedridden for a long time. All the above structures can be made of flexible plastic, with low cost and will not hurt the patient.

[0023] On the outer sides of the two winding devices 14, there are a first winding elastic band 26 and a second winding elastic band 27 respectively. On the outer side of the first winding elastic band 26, there is a snap button 24. On the outer side of the second winding elastic band 27, there is a card slot 28. The rewinder 14 is a tape spring, which can correspondingly wind up the first winding elastic band 26 and the second winding elastic band 27. The purpose is to store the first winding elastic band 26 and the second winding elastic band 27 after they are used. When it is necessary to cooperate with the patient to be fixed on the leg for assembly, the first winding elastic band 26 and the second winding elastic band 27 are pulled closer, and the snap button 24 is correspondingly snapped onto the card slot 28, and the first winding elastic band 26 and the second winding elastic band 27 will wrap the leg.

[0024] The fitting piece includes card shells 16 respectively arranged on the outer side of the rear end of the bag body 1, and buffer members are arranged inside both groups of card shells 16; The card shell 16 facilitates the assembly of the airbag 31.

[0025] The buffer member includes an airbag 31. The airbag 31 is located inside the card shell 16. An arc-shaped abutting plate 15 is arranged on the outer side of the card shell 16. Two groups of buzzers 30 are arranged on the inner wall of the abutting plate 15. A pressure sensor is arranged on the upper part of the airbag 31. A liquid level mark 2 is arranged on the outer side of the front end of the bag body 1. The pressure sensor is electrically connected to the buzzer 30. When the air pressure change inside the airbag 31 can be detected by the pressure sensor, an alarm is triggered. The set liquid level mark 2 can be used to observe the liquid level inside the bag body 1 visually.

[0026] Working principle: During use, different usage methods can be adopted according to the needs of the patient and the actual situation of the hospital bed. When hanging the bag body 1, the corresponding card rod 11 is pulled out from inside the L-shaped sliding frame 9 and snapped onto the side frame of the hospital bed. The magnetic snap button 29 will attract to the side frame of the hospital bed. At the same time, the L-shaped hanging and the pressing of the hospital bed mattress are carried out until the bag body 1 can be suspended below the outside of the hospital bed. If the side frame of the hospital bed cannot be used, the conventional hanging ring 5 and the elastic clip 17 can be used to hang the bag body 1 on the guardrail of the hospital bed for use. Multiple methods can cope with many occasions; During the use process, the catheter 4 is connected to the incision. By setting a backflow valve 10 at the catheter 4, the reverse flow of the liquid in the bag body 1 can be avoided. And when the liquid volume in the bag body 1 exceeds the card strip 22 area and overflows from the card tube 23, at this time, the floating plate 18 and the abutting rod 19 at the card tube 23 will move up at the card tube 23 under the push of the air pressure and liquid level inside the bag body 1, causing the abutting ball 21 at the end of the abutting rod 19 to fit against the airbag 31. After the airbag 31 is squeezed inside, the internal pressure increases. When the pressure change exceeds the preset threshold, it will pass through the pressure sensor and make the buzzer 30 sound, thereby warning the current liquid level and reminding the personnel to discharge; When the patient walks, the first winding elastic band 26 and the second winding elastic band 27 at the lower end of the card rod 11 can be pulled closer to each other and tied to the leg. The button 24 on the first winding elastic band 26 is clamped outside the second winding elastic band 27, so as to fix the bag body 1 on the leg. Thus, during the movement of the patient, the pressure can be reduced and the movement can be more agile.
