Biomedical engineering industry medical flushing equipment

Abstract

This invention discloses a medical flushing device for biomedical engineering industry, relating to the field of biomedical engineering technology. It includes a medication sac assembly and an infusion tubing. The medication sac assembly comprises a corrugated sac body with a lower plastic plate at its bottom and a threaded opening on the surface of an upper plastic plate. The infusion tubing has outlet holes on both its top outer wall and top surface. First magnetic plates are fixed to both sides of the lower surface of the upper plastic plate, and second magnetic plates are fixed to both sides of the upper surface of the lower plastic plate. This medical flushing device, through the magnetic attraction principle of the first and second magnetic plates, ensures that the corrugated sac body is attracted and fixed after compression. Even if the pressure on the corrugated sac body is released before the infusion tubing is withdrawn from the vagina, the corrugated sac body will not recover and generate suction, preventing the backflow of flushing fluid or medication from the vagina. This ensures thorough flushing of the vaginal wall while preventing backflow contamination of remaining medication.

Description

Technical Field

[0001] This invention relates to the field of biomedical engineering technology, specifically to a medical rinsing device for biomedical engineering. Background Technology

[0002] Disposable vaginal douches, as medical irrigation devices, are an important branch of the biomedical engineering industry. They are medical-grade disposable medical devices designed specifically for women, used for vaginal cleaning and adjunctive treatment. They are made of medical-grade non-toxic polymer materials (usually polyethylene PE or polypropylene PP) and are sterilized with ethylene oxide to ensure sterility. Their working principle is to generate pressure by squeezing the bottle, causing the liquid to spray out from the douche head to rinse the vaginal wall.

[0003] In actual use, existing disposable vaginal douches require squeezing the reservoir after the irrigation tube is inserted into the vagina to expel the liquid inside and rinse the vagina. However, users often release the pressure before the tube is withdrawn from the vagina, causing the reservoir to automatically return to its original position and generate suction. This results in the backflow of the douche liquid into the vagina, leading to incomplete rinsing. Furthermore, the backflowed liquid mixes with the unused liquid, causing contamination. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a medical rinsing device for the biomedical engineering industry, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a medical flushing device for biomedical engineering industry, comprising a drug-filled bladder assembly and an infusion pipeline. The drug-filled bladder assembly includes a corrugated bladder body, with an upper plastic plate at the top and a lower plastic plate at the bottom. The upper plastic plate has a threaded opening on its surface, and an infusion pipeline is threadedly connected to the outer wall of the threaded opening. The infusion pipeline has outlet holes on both its top outer wall surface and top surface. A first magnetic sheet is fixed to both sides of the lower surface of the upper plastic plate, and a second magnetic sheet is fixed to both sides of the upper surface of the lower plastic plate.

[0006] Furthermore, both the infusion tubing and the corrugated bladder are filled with flushing fluid or medication, and a limit ring is provided inside the bottom end of the infusion tubing.

[0007] Furthermore, an isolation piston is provided inside the infusion pipeline above the limiting ring, and the outer diameter of the isolation piston is adapted to the inner diameter of the infusion pipeline.

[0008] Furthermore, the outer wall of the infusion pipeline is fitted with a pipe cap assembly, and the pipe cap assembly includes a pipe sleeve.

[0009] Furthermore, a central thin column is fixed to the top of the inner wall of the sleeve, and the central thin column penetrates the outlet hole on the top surface of the infusion pipe.

[0010] Furthermore, the bottom of the sleeve is provided with a ring-shaped groove, and a card is engaged inside the groove.

[0011] Furthermore, the card is fixed to the bottom outer wall of the infusion pipeline, and the infusion pipeline is connected to the tube sleeve through the card slot and the card.

[0012] Furthermore, the bottom of the central thin column abuts against the top surface of the isolation piston, and the infusion pipeline is connected to the corrugated bladder body through a threaded port.

[0013] This invention provides a medical flushing device for the biomedical engineering industry, which has the following beneficial effects:

[0014] 1. This biomedical engineering industrial medical flushing device uses the magnetic attraction principle of the first and second magnetic sheets. After the corrugated bladder is compressed, it will be attracted and fixed. Even if the pressure on the corrugated bladder is released before the infusion tube is withdrawn from the vagina, the corrugated bladder will not recover and generate suction, thus avoiding the backflow of flushing fluid or medication in the vagina. This ensures that the vaginal wall is thoroughly flushed and prevents backflow of liquid from contaminating the remaining medication.

[0015] 2. This biomedical engineering industrial medical flushing device is filled with disposable liquid in both the infusion tubing and the corrugated bladder. The liquid in the two spaces is isolated by an isolation piston, and the liquid inside the infusion tubing is pushed in by transmission. After the infusion tubing is withdrawn and the sleeve is put on, the corrugated bladder automatically returns to its original position by pushing the isolation piston back through the central thin column. At this time, the sleeve is engaged with the infusion tubing through a slot and a clip. At this point, the sleeve can be rotated without contacting the outer wall of the infusion tubing to separate it from the threaded end, thus exposing the threaded end. By pressing the corrugated bladder through the exposed threaded end, the unused liquid inside can be used to flush the vagina externally, thus achieving two uses in one device.

Detailed Implementation

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0023] like Figures 1-5 As shown, the present invention provides a technical solution: a medical flushing device for biomedical engineering industry, including a drug-filled bladder assembly 1 and an infusion pipe 2. The drug-filled bladder assembly 1 includes a corrugated bladder body 101, and an upper plastic plate 102 is provided on the top of the corrugated bladder body 101, and a lower plastic plate 103 is provided on the bottom of the corrugated bladder body 101. A threaded opening 104 is provided on the surface of the upper plastic plate 102, and an infusion pipe 2 is threadedly connected to the outer wall of the threaded opening 104. An outlet hole 3 is provided on both the outer wall surface and the top surface of the infusion pipe 2. A first magnetic sheet 105 is fixed on both sides of the lower surface of the upper plastic plate 102, and a second magnetic sheet 106 is fixed on both sides of the upper surface of the lower plastic plate 103.

[0024] The specific operation is as follows: The biomedical engineering industrial medical irrigation device is a disposable vaginal irrigator. When using the disposable vaginal irrigator, the infusion tube 2 is inserted into the vagina. At this time, the user's index and middle fingers hold the upper surface of the plastic plate 102 on both sides, while the thumb presses down on the lower surface of the plastic plate 103 and applies force. At this time, under the force of the hand, the corrugated capsule 101 is compressed, so that the irrigation fluid or medicine flows along the inside of the infusion tube 2 and flows out from the outlet hole 3 into the vagina.

[0025] When the corrugated bladder 101 is compressed to its limit, the second magnetic piece 106 on the upper surface of the lower plastic plate 103 and the first magnetic piece 105 on the lower surface of the upper plastic plate 102 are attached together. At this time, the first magnetic piece 105 and the second magnetic piece 106 are magnetically attracted together, and the magnetic attraction force is greater than the recovery force of the corrugated bladder 101 after it is released. Even if the user releases the pressure before the infusion tube 2 is withdrawn from the vagina, the corrugated bladder 101 will not recover under the magnetic attraction force of the first magnetic piece 105 and the second magnetic piece 106. Therefore, the irrigation fluid or medicine entering the vagina is prevented from being drawn back due to the recovery of the corrugated bladder 101.

[0026] Based on the above description, the present invention utilizes the magnetic attraction principle of the first magnetic piece 105 and the second magnetic piece 106. After compression, the corrugated bladder 101 will be attracted and fixed. Even if the pressure on the corrugated bladder 101 is released before the infusion tube 2 is withdrawn from the vagina, the corrugated bladder 101 will not recover and generate suction, thus preventing the backflow of the vaginal rinsing fluid or medication. This ensures thorough rinsing of the vaginal wall and prevents backflow of liquid from contaminating the remaining medication.

[0027] like Figures 1-5 As shown, both the infusion tubing 2 and the corrugated bag 101 are filled with flushing fluid or medication. A limiting ring 4 is installed inside the bottom of the infusion tubing 2. An isolation piston 5 is installed above the limiting ring 4 inside the infusion tubing 2, and the outer diameter of the isolation piston 5 matches the inner diameter of the infusion tubing 2. A tube cap assembly 6 is fitted onto the outer wall of the infusion tubing 2, and the tube cap assembly 6 includes a tube sleeve 601. A central thin column 602 is fixed to the top of the inner wall of the tube sleeve 601. The column 602 penetrates the outlet hole 3 on the top surface of the infusion pipeline 2. The bottom of the sleeve 601 is provided with a groove 603 in an annular shape, and a card 604 is engaged inside the groove 603. The card 604 is fixed to the bottom outer wall of the infusion pipeline 2, and the infusion pipeline 2 is engaged with the sleeve 601 through the groove 603 and the card 604. The bottom of the central thin column 602 abuts against the top surface of the isolation piston 5. The infusion pipeline 2 is connected to the corrugated bladder 101 through the threaded port 104.

[0028] The specific operation is as follows: when the infusion tubing 2 is inserted into the vagina, the tube sleeve 601 is removed in advance. When the corrugated balloon 101 is pressed, the isolation piston 5 isolates the infusion tubing 2 from the internal space of the corrugated balloon 101. The infusion tubing 2 is pre-filled with a single-use flushing solution or medication. Therefore, when the corrugated balloon 101 is pressed, the isolation piston 5 is pushed by transmission, causing the flushing solution or medication inside the infusion tubing 2 to be pushed out. The flushing solution or medication inside the corrugated balloon 101 only enters the infusion tubing 2 and does not exit.

[0029] After a single dose of rinsing solution or medication is injected into the vagina, the infusion tubing 2 is pulled out of the vagina. Then, the sleeve 601 is fitted onto the outside of the infusion tubing 2, and the groove 603 at the bottom of the sleeve 601 engages with the card 604 on the outer wall of the bottom of the infusion tubing 2. At this time, the central thin column 602 is inserted into the infusion tubing 2 through the outlet hole 3 when the sleeve 601 is fitted. The central thin column 602 pushes the isolation piston 5 back, thereby pushing the rinsing solution or medication that has entered the infusion tubing 2 back into the corrugated bladder 101. As the rinsing solution or medication re-enters the corrugated bladder 101, the first magnetic piece 105 and the second magnetic piece 106 separate under the force of the liquid entering, allowing the corrugated bladder 101 to recover.

[0030] Then rotate the sleeve 601 so that it drives the infusion tubing 2 to rotate through the slot 603 and the card 604 to separate it from the threaded port 104. At this time, the threaded port 104 of the corrugated bag 101 is exposed, while the isolation piston 5 is restricted by the limiting ring 4 to prevent it from falling out. After that, simply align the threaded port 104 with the outside of the vagina and press the corrugated bag 101 once to allow the unused medicine or flushing solution inside to flow out from the threaded port 104 to flush the outside of the vagina.

[0031] Based on the above description, both the infusion tubing 2 and the corrugated capsule 101 of the present invention are filled with a single-use liquid volume. The liquid in the two spaces is isolated by the isolation piston 5, and the liquid inside the infusion tubing 2 is pushed by the transmission. After the infusion tubing 2 is pulled out and the sleeve 601 is put on, the corrugated capsule 101 is automatically restored by the central thin column 602 pushing the isolation piston 5. At this time, the sleeve 601 is engaged with the infusion tubing 2 through the slot 603 and the card 604. At this time, the sleeve 601 can be rotated without contacting the outer wall of the infusion tubing 2 to make it rotate and separate from the threaded opening 104, thereby exposing the threaded opening 104. By pressing the corrugated capsule 101 through the exposed threaded opening 104, the unused liquid inside can be used to complete the external vaginal irrigation, thus realizing two uses in one device.

[0032] In summary, when using this biomedical engineering industrial medical irrigation device, the user first inserts the infusion tube 2 into the vagina. At this time, the user's index and middle fingers hold the upper plastic plate 102 on both sides, while the thumb presses down on the lower plastic plate 103 and applies force. Under the force of the hand, the corrugated capsule 101 is compressed, causing the irrigation fluid or medicine to flow along the inside of the infusion tube 2 and flow out from the outlet 3 into the vagina.

[0033] When the corrugated bladder 101 is compressed to its limit, the second magnetic piece 106 on the upper surface of the lower plastic plate 103 and the first magnetic piece 105 on the lower surface of the upper plastic plate 102 are attached together. At this time, the first magnetic piece 105 and the second magnetic piece 106 are magnetically attracted together, and the magnetic attraction force is greater than the recovery force of the corrugated bladder 101 after it is released. Even if the user releases the pressure before the infusion tube 2 is withdrawn from the vagina, the corrugated bladder 101 will not recover under the magnetic attraction force of the first magnetic piece 105 and the second magnetic piece 106. Therefore, the irrigation fluid or medicine entering the vagina is prevented from being drawn back due to the recovery of the corrugated bladder 101.

[0034] When the infusion tubing 2 is inserted into the vagina, the tube sleeve 601 is removed beforehand. When the corrugated balloon 101 is pressed, the isolation piston 5 isolates the infusion tubing 2 from the internal space of the corrugated balloon 101. The infusion tubing 2 is pre-filled with a single-use flushing solution or medication. Therefore, when the corrugated balloon 101 is pressed, the isolation piston 5 is pushed by transmission, causing the flushing solution or medication inside the infusion tubing 2 to be pushed out. The flushing solution or medication inside the corrugated balloon 101 only enters the infusion tubing 2 and does not exit.

[0035] After a single dose of rinsing solution or medication is injected into the vagina, the infusion tubing 2 is pulled out of the vagina. Then, the sleeve 601 is fitted onto the outside of the infusion tubing 2, and the groove 603 at the bottom of the sleeve 601 engages with the card 604 on the outer wall of the bottom of the infusion tubing 2. At this time, the central thin column 602 is inserted into the infusion tubing 2 through the outlet hole 3 when the sleeve 601 is fitted. The central thin column 602 pushes the isolation piston 5 back, thereby pushing the rinsing solution or medication that has entered the infusion tubing 2 back into the corrugated bladder 101. As the rinsing solution or medication re-enters the corrugated bladder 101, the first magnetic piece 105 and the second magnetic piece 106 separate under the force of the liquid entering, allowing the corrugated bladder 101 to recover.

[0036] Then, rotate the sleeve 601 so that it drives the infusion tubing 2 to rotate through the slot 603 and the card 604, so that it separates from the threaded port 104. At this time, the threaded port 104 of the corrugated bag 101 is exposed, while the isolation piston 5 is restricted by the limiting ring 4 to prevent it from falling out. After that, simply align the threaded port 104 with the outside of the vagina and press the corrugated bag 101 once to allow the unused medicine or flushing solution inside to flow out from the threaded port 104 to flush the outside of the vagina, thus achieving two uses in one device without affecting each other.
