Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical drainage device. Background Technology

[0002] Medical drainage devices are generally used to collect urine from patients with indwelling urinary catheters. They typically consist of a collection bottle and a collection bag. The collection bag is attached to the collection bottle, which is used to measure urine volume. In use, urine flows through the indwelling catheter to the collection bottle, and then from the collection bottle to the urine collection bag.

[0003] In existing drainage devices, the urine collection bag is directly connected to the collection bottle through a pipe. When the urine bag is full, it needs to be removed and replaced with a new one. During the replacement process, outside air enters the measuring bottle through the pipe. The measuring bottle is then connected to the human body through a catheter. This means that bacteria from the outside air may enter the human body and cause infection, posing a certain risk. Existing drainage devices do not have antibacterial devices to solve the above problems. Summary of the Invention

[0004] To address the problem that existing drainage devices lack antibacterial devices and pose a risk of bacterial infection during use, this application provides a medical drainage device.

[0005] This application provides a medical drainage device with the following technical solution: A medical drainage device includes a measuring bottle and a collection tube. The collection tube is rotatably inserted into the measuring bottle. An overflow hole communicating with the measuring bottle is opened on the side wall of the collection tube. A conduit is connected to the upper end of the collection tube. A connecting part for communicating with a urine bag is provided at the bottom of the measuring bottle. The device also includes a bacterial filter. The bacterial filter is disposed in the fluid passage of the drainage device. The bacterial filter includes a matching upper cover and a lower cover, forming a cavity between the upper cover and the lower cover. A filter membrane is disposed inside the cavity. An upper connecting tube is disposed in the middle of the upper part of the upper cover, and a lower connecting tube is disposed in the middle of the bottom surface of the lower cover. The bacterial filter is connected to the fluid passage of the drainage device through the upper connecting tube and the lower connecting tube.

[0006] By adopting the above technical solution, the urine bag is connected to the measuring bottle via a connecting part. When the drainage device is working, the catheter is connected to the human body, and urine enters through the catheter and is stored inside the collection tube. When the urine level inside the collection tube is higher than the lower overflow hole, the urine enters the measuring bottle through the lower overflow hole and is stored in the measuring bottle. The urine can be measured through the measuring bottle. When it is necessary to drain the urine, the collection tube is lifted upward, and the collection tube is separated from the connecting part at the bottom of the measuring bottle. At this time, the connecting part is connected to the inside of the measuring bottle, and the urine inside the measuring bottle enters the urine bag for storage through the connecting part. The bacterial filtration device can be set at the connection between the connecting part and the urine bag, or at the connection between the catheter and the collection tube. When the urine bag is changed, the inside of the drainage device is connected to the outside. When air enters, the bacterial filtration device can filter bacteria in the air, thereby preventing bacteria from entering the human body through the catheter and causing infection, thus reducing the patient's risk of infection.

[0007] Optionally, the catheter is a multi-channel tube, and the catheter has at least two channels inside.

[0008] By adopting the above technical solution, multiple channels are set inside the catheter. When urine enters the catheter, the air inside the catheter and the measuring bottle causes the air to be expelled slowly during urine transport, resulting in slow urine transport. When multiple channels are set inside the catheter, a loop is formed between the multiple channels. One channel is used to transport urine, and another channel can be used to expel air, thereby improving the transport rate of the catheter and avoiding urine accumulation in the catheter.

[0009] Optionally, an end cap is provided above the collection tube, the conduit is connected to the end cap, an overflow tube is provided inside the collection tube, an upper overflow hole communicating with the overflow tube is provided on the side wall of the collection tube, a protrusion is provided at the bottom of the collection tube, a drain hole communicating with the overflow tube is opened in the center of the protrusion, and the collection tube is inserted into the middle of the connecting part at the bottom of the metering bottle through the protrusion.

[0010] By adopting the above technical solution, when the urine level inside the measuring bottle exceeds the upper overflow hole, the urine enters the overflow pipe inside the collection tube through the upper overflow hole. The bottom of the overflow pipe is connected to the drain hole, and the urine flows from the drain hole into the urine bag for storage through the connection part at the bottom of the measuring bottle. This avoids excess urine flowing back through the tube when the measuring bottle is full of urine.

[0011] Optionally, the connecting part has a stepped interior, forming a first drainage chamber and a second drainage chamber. The lower end of the collecting tube is inserted into the first drainage chamber, and the protrusion is inserted into the second drainage chamber. A through hole is provided on one side of the bottom surface of the collecting tube, connecting the interior of the collecting tube and the first drainage chamber.

[0012] By adopting the above technical solution, when it is necessary to discharge urine from the measuring bottle into the urine bag, the collecting tube is lifted upwards. The protrusion at the lower end of the collecting tube first disengages from the second drainage chamber. At this time, the first drainage chamber and the second drainage chamber are connected. The urine in the collecting tube enters the first drainage chamber and the second drainage chamber through the through hole and is discharged, thereby discharging the urine inside the collecting tube. Then, the collecting tube is lifted upwards again. At this time, the bottom of the collecting tube disengages from the first drainage chamber. The first drainage chamber is connected to the inside of the measuring bottle. The urine inside the measuring bottle is discharged through the first drainage chamber and the second drainage chamber, thereby discharging the urine in the measuring bottle.

[0013] Optionally, a guide component is provided above the collection tube at the connection point with the metering bottle to lift the collection tube upwards during rotation.

[0014] By adopting the above technical solution and setting a guide component, the collection tube is synchronously lifted upward under the action of the guide component when the collection tube is rotated, thereby realizing the control of liquid discharge by rotating the collection tube.

[0015] Optionally, a one-way valve is provided at the connection between the conduit and the end cap, and a breathable membrane for discharging gas is provided on the end cap.

[0016] By adopting the above technical solution, a one-way valve is set to prevent urine from flowing back into the catheter, and a breathable membrane is set to allow gas inside the measuring bottle to be discharged from the breathable membrane, thereby facilitating the entry of urine into the measuring bottle.

[0017] Optionally, sealing rings are provided at both ends of the collection tube where it connects to the metering bottle.

[0018] By adopting the above technical solution, the sealing performance of the connection between the collection tube and both ends of the metering bottle is improved by setting a sealing ring.

[0019] Optionally, a fixing clip is also included, which is disposed at the connection between the metering bottle and the urine bag. The fixing clip includes a fixing sleeve and a nut. The fixing sleeve is flared and has several grooves on its surface. The outer surface of the fixing sleeve is threaded, and the nut is threadedly connected to the fixing sleeve.

[0020] By adopting the above technical solution, when the urine bag is connected to the measuring bottle, the fixing sleeve is set on the outside of the connection between the measuring bottle and the urine bag. Then, the nut is rotated, and the nut moves downward through the action of the thread. Since the fixing sleeve is flared, the nut presses the lower end of the fixing sleeve inward during the downward movement, thereby pressing the connection between the measuring bottle and the urine bag tightly through the fixing sleeve to prevent it from falling off.

[0021] Optionally, hanging racks are provided on both sides of the bottom of the measuring bottle.

[0022] By adopting the above technical solution, when the urine bag is connected to the measuring bottle, the two sides of the urine bag are connected to the hanger through the through holes. The hanger supports the urine bag and improves the stability of the connection between the urine bag and the measuring bottle.

[0023] Optionally, a spiral sheath is provided on the outside of the connection between the conduit and the end cap.

[0024] By adopting the above technical solution, the sheath protects the connection between the catheter and the end cap, preventing the catheter from bending and becoming blocked during use.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This application includes a bacterial filtration device connected to the pipeline of the metering bottle. When outside air enters the metering bottle, the bacterial filtration device filters out bacteria in the air, thereby effectively preventing bacteria from entering the human body and causing infection, and effectively improving the safety of the drainage device.

[0027] 2. The catheter in this application is a multi-channel catheter, with multiple channels forming a loop. One channel is used to deliver urine, and another channel can be used to expel gas, thereby improving the delivery rate of the catheter and preventing urine from accumulating in the catheter.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This embodiment discloses a medical drainage device.

[0040] Reference Figure 1 and Figure 2 A medical drainage device includes a measuring bottle 1 and a collection tube 2. The measuring bottle 1 has a scale for measurement on its surface. The measuring bottle 1 has an opening at the top and a connecting part 26 at the bottom. The collection tube 2 passes through the opening at the top of the measuring bottle 1 and is inserted into the measuring bottle 1. The upper part of the collection tube 2 is connected to a catheter 3. The lower end of the collection tube 2 is inserted into the connecting part 26. A bacterial filter 4 is connected below the connecting part 26. The bottom of the measuring bottle 1 has a bracket 6 for connecting a urine bag on both sides. The bracket 6 is in the shape of an inverted T. The bracket 6 has outwardly protruding hooks on both sides for connecting to the connection holes on the urine bag.

[0041] Reference Figure 3 and Figure 4 The collecting tube 2 includes a tube body 13, which is hollow inside. An end cap 12 is provided on the top of the tube body 13. A conduit 3 is connected to the end cap 12 and communicates with the inside of the tube body 13. A one-way valve is provided at the connection between the conduit 3 and the end cap 12. A breathable membrane for venting air from the inside of the tube body 13 is provided on the surface of the end cap 12. A protruding part 16 is provided at the lower end of the tube body 13. A drain hole 15 is provided in the middle of the protruding part 16. A through hole 14 communicating with the inside of the tube body 13 is opened on one side of the protruding part 16 on the bottom surface of the tube body 13. Two lower overflow holes 11 are opened on the surface of the collecting tube 2. An overflow tube 17 is provided inside the collecting tube 2. The overflow tube 17 extends to the upper part of the inside of the collecting tube 2. The lower end of the overflow tube 17 communicates with the drain hole 15. An upper overflow hole 10 communicating with the overflow tube 17 is opened on the side wall of the collecting tube 2. The height of the upper overflow hole 10 is higher than that of the lower overflow hole 11. Two sealing rings 8 are provided at the connection between the upper and lower ends of the collecting tube 2 and the metering bottle 1.

[0042] A guide component 9 is also provided on one side of the upper end of the tube body 13. The guide component 9 includes a guide block provided on the tube body 13 and a guide groove provided at the opening of the metering bottle 1. The guide groove is an upwardly extending arc shape. The guide block is movably provided inside the guide groove. When the tube body 13 rotates, the guide block moves along the guide groove and drives the tube body 13 to be lifted upward.

[0043] Reference Figure 5 The catheter 3 is a multi-channel tube with two channels 18 inside. When urine enters the catheter, the air inside the catheter 3 and the measuring bottle 1 causes the air to be expelled slowly during urine transport, resulting in slow urine transport. When the catheter 3 is equipped with two channels 18, a loop is formed between the two channels 18. One channel 18 is used to transport urine, and the other channel 18 can be used to expel air, thereby improving the transport rate of the catheter and preventing urine from accumulating in the catheter 3.

[0044] Reference Figure 6 The bacterial filtration device 4 includes a matching upper cover 19 and a lower cover 20, forming a cavity between the upper cover 19 and the lower cover 20. A filter membrane is installed inside the cavity. An upper connecting pipe 22 is installed in the middle of the upper part of the upper cover 19, and a lower connecting pipe 23 is installed in the middle of the bottom surface of the lower cover 20. The upper connecting pipe 22 is connected to the connecting part of the measuring bottle 1, and the lower connecting pipe 23 is connected to the urine bag.

[0045] A fixing clip 7 is fitted onto the lower connecting tube 23. The fixing clip 7 includes a fixing sleeve 25 and a nut 24. The fixing sleeve 25 is flared and has several grooves on its surface. The outer surface of the fixing sleeve 25 is threaded. The nut 24 is threadedly connected to the fixing sleeve. When the urine bag is connected to the lower connecting tube 23, the fixing clip 7 is fitted onto the outside of the connection between the lower connecting tube 23 and the urine bag. Then, the nut 24 is rotated. The nut 24 moves downward through the action of the thread. Since the fixing sleeve 25 is flared, the nut 24 presses the lower end of the fixing sleeve 25 inward during the downward movement, thereby pressing the connection between the lower connecting tube 23 and the urine bag tightly through the fixing sleeve 25 to prevent it from falling off.

[0046] Reference Figure 7 The interior of the connecting part 26 is stepped, and the interior of the connecting part 26 forms a first drain chamber 27 and a second drain chamber 28. The lower end of the collecting tube 2 is inserted into the first drain chamber 27, and the protrusion 16 is inserted into the second drain chamber 28. The through hole 14 on the bottom surface of the collecting tube 2 connects the interior of the collecting tube 2 and the first drain chamber 27.

[0047] The implementation principle of a medical drainage device in this embodiment is as follows: A collection tube 2 is inserted into a measuring bottle 1. A urine bag is connected to the lower connecting tube 23 of a bacterial filtration device 4 via a pipe. The lower connecting tube 23 is fixed to the urine bag pipe using a fixing clip 7. Then, both sides of the urine bag are connected to a hanging bracket 6. Urine enters the collection tube 2 through a conduit 3. When the urine level in the collection tube 2 exceeds the lower overflow hole 11, the urine enters the measuring bottle 1 through the lower overflow hole 11 for storage. The amount of urine discharged can be measured by the scale on the surface of the measuring bottle 1. When the urine level in the measuring bottle 1 reaches the upper overflow hole 10, the urine enters the overflow pipe 17 inside the collection tube 2 through the upper overflow hole 10, and is discharged into the urine bag for storage via the overflow pipe 17, the drain hole 15, and the connecting part 26. This prevents urine from being unable to enter the measuring bottle 1 when it is full. When it is necessary to discharge urine from the measuring bottle 1 into the urine bag, the collection tube 2 is rotated. As the collecting tube 2 rotates, it is lifted upwards. The protrusion 16 at the lower end of the collecting tube 2 first disengages from the second drainage chamber 28. At this time, the first drainage chamber 27 and the second drainage chamber 28 are connected. The urine in the collecting tube 2 enters the first drainage chamber 27 and the second drainage chamber 28 through the through hole 14 and is discharged, thereby draining the urine inside the collecting tube 2. Then, the collecting tube 2 continues to rotate and is lifted upwards. At this time, the bottom of the collecting tube 2 disengages from the first drainage chamber 27. The first drainage chamber 27 is connected to the inside of the measuring bottle 1. The urine inside the measuring bottle 1 is discharged through the first drainage chamber 27 and the second drainage chamber 28, thereby draining the urine in the measuring bottle 1 into the urine bag. When the urine bag is replaced, after the urine bag is disassembled, the air first enters the bacterial filter device 4. The filter membrane in the bacterial filter device 4 removes bacteria from the air, thereby preventing bacteria from entering the drainage device's tubing and causing human infection.

[0048] In summary, this application incorporates a bacterial filtration device connected to the tubing of the metering bottle. When outside air enters the bottle, the bacterial filtration device filters out bacteria from the air, effectively preventing bacteria from entering the body and causing infection, thus significantly improving the safety performance of the drainage device. Furthermore, the catheter in this application is a multi-channel catheter, with multiple channels forming a loop. One channel is used to transport urine, while another channel can be used to expel gas, thereby increasing the catheter's delivery rate and preventing urine accumulation within the catheter. Therefore, this application effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0049] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered within the protection scope of this application.
