Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a constant temperature debubbler for hemodialysis. Background Art

[0002] Hemodialysis (HD) is a renal replacement therapy for patients with acute and chronic renal failure. During hemodialysis, air can enter the hemodialysis machine due to disconnections between the arterial needle and catheter, a loose arterial pressure Luer connector, holes in the arterial catheter that allow air to enter the arterial line, air entering during anticoagulation or saline administration, and insufficient priming that allows air to enter the dialyzer or tubing. This can lead to the formation of numerous bubbles within the hemodialysis machine. The generation of numerous bubbles during hemodialysis is extremely dangerous. If bubbles are not promptly eliminated, they can eventually enter the body through the bloodstream. More than 10ml of air entering the body can cause vascular embolism, which can lead to symptoms such as acute dyspnea, coughing, chest pain, chest tightness, wheezing, and cyanosis. In severe cases, convulsions, coma, and even death may occur. Therefore, the continuous and effective removal of bubbles within the hemodialysis machine is extremely important.

[0003] At present, the method for eliminating bubbles in the hemodialysis machine in the existing technology is that when medical personnel detect bubbles in the corresponding part of the hemodialysis machine, they directly use their hands or other relatively soft instruments to appropriately knock on the bubble adhesion area, so that the bubbles attached to the inner wall of the hemodialysis machine are vibrated and bounced off, then float up and break and gather into air. The air gathers in the dialyzer. First, a 20 ml syringe needs to be connected to the arterial pot and the venous pot. First, the arterial pot is filled. The dialyzer is inverted with the arterial end at the bottom, and the air is exhausted at a slow pump speed. A large amount of air will be generated in the dialysis pipeline and the dialyzer in the venous pot. At this time, it is necessary to continuously suck out the air at the venous pot end until the tiny bubbles are sucked out. Only then can dialysis continue.

[0004] At present, in the existing technology, medical personnel manually perform defoaming, which requires real-time monitoring of whether there are bubbles or air generated in the dialyzer, and manually knocking and vibrating the dialyzer according to the actual monitoring situation. The knocking force provided by manual knocking is unstable, and it is easy for the knocking force to fail to provide effective vibration and fail to shake off the bubbles, or the knocking force is too large to damage the dialyzer. In addition, medical personnel are required to manually and continuously extract air and blood foam from the venous bottle. The operation is very complicated, and the dialyzer needs to be rotated during the process, which is very labor-intensive for medical personnel. Manual operation is also prone to operational errors, resulting in incomplete defoaming, causing residual bubbles to enter the human body and cause damage to the patient's body. In addition, the defoaming operation in the existing technology will take a certain amount of time, which will cause the blood in the dialyzer to cool down, resulting in a large temperature difference between the blood temperature in the dialyzer and the patient's own temperature. If it is directly input into the human body, it will cause certain damage to the body. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a constant temperature debubble remover for hemodialysis. By setting up a constant temperature debubble remover with ultrasonic bubble air identification structure, flip vibration debubble remover structure and automatic suction debubble remover structure, the problem in the prior art is that there is a lack of debubble removers that can automatically identify bubble air and collect bubbles through stable and continuous vibration and then use automatic suction structure to remove bubbles. As a result, it is impossible to accurately identify bubble air and automatically and stably remove bubbles in the dialyzer, which not only consumes a large amount of medical human resources but also allows some bubbles to enter the human body, causing harm to the human body or even posing a fatal risk. It also makes it impossible to keep the blood temperature constant after the bubbles are removed, causing low-temperature blood to enter the human body and damage the patient's body.

[0006] The present invention is achieved through the following technical solutions:

[0007] A constant temperature debubbler for hemodialysis comprises a central control connecting frame, a flip vibrator is provided in front of the central control connecting frame via an electromagnetic slide rail, ultrasonic bubble detectors are fixedly provided at both the upper and lower ends of the flip vibrator, and a venous pot debubbler is fixedly provided on the right side of the central control connecting frame via a line.

The flip vibrator includes a left flip vibration sleeve 7 and a right flip vibration sleeve 8, the rotating support arm is directly fixedly connected to the left flip vibration sleeve and the right flip vibration sleeve, and the upper and lower ends of the left flip vibration sleeve are A left semicircular limiting fixing plate 9 is fixedly provided, and a right semicircular limiting fixing plate 10 is fixedly provided at both ends of the right flip vibration sleeve. The left semicircular limiting fixing plate and the right semicircular limiting fixing plate are fitted to form a circular baffle for limiting. A fixed buckle groove 11 is fixedly provided on the upper edge of the right semicircular limiting fixing plate, and a fixed buckle head 12 is fixedly provided on the upper edge of the left semicircular limiting fixing plate. Since the fixed buckle head and the fixed buckle groove cooperate, the limiting fixation can be completed by aligning and inserting the two. A multifunctional buckle is fixedly provided between the left semicircular limiting fixing plate and the right semicircular limiting fixing plate. The connecting column 13 is fixed with a constant temperature heating strip on the inner wall of the multifunctional connecting column. The surface of the constant temperature heating strip coincides with the inner wall surface of the multifunctional connecting column. When the inner wall surface of the multifunctional connecting column is in contact with the dialyzer tube wall, it will continue to heat it so that the internal temperature of the dialyzer can be relatively stable within the set range. A sliding groove 14 is provided on the side of the multifunctional connecting column. A sliding vibration table 15 is slidingly provided on the outer side of the multi-kinetic energy connecting column. The sliding vibration table includes a sliding base 16. An electromagnetic sliding block 17 is provided at the end of the sliding base. The sliding vibration table is connected to the multi-kinetic energy by cooperating with the sliding groove. The connecting columns are connected, and a rotating vibration arm 18 is fixedly provided at the upper end of the sliding base. The rotating vibration arm includes an electric rotating connecting rod 19. A vibration generator 28 is fixedly provided on the top of the electric rotating connecting rod. The vibration generator includes an electric vibration block and a flexible sheath fixedly mounted on the outside of the electric vibration block, thereby ensuring that the vibration generator does not damage the outer wall of the dialyzer when it vibrates. Ultrasonic bubble detectors 20 are fixedly provided at the upper ends of the left semicircular limit fixing plate and the right semicircular limit fixing plate, and pipeline passages are opened at the centers of the left semicircular limit fixing plate and the right semicircular limit fixing plate.

[0033] An intravenous pot defoamer 22 is fixedly provided on the right side of the central control connecting frame through a line. The intravenous pot defoamer includes a central connecting block 23. A intravenous pot fixing sleeve 24 is fixedly provided at the lower end of the central connecting block. An ultrasonic bubble detector 25 is fixedly provided above the intravenous pot fixing sleeve. A bubble suction insertion needle 26 is fixedly provided on the right side of the ultrasonic bubble detector. The bubble suction insertion needle is connected to a waste liquid storage tube 27 for containing the extracted air and blood foam through a suction machine.

[0034] When implementing this embodiment, the whole is first controlled by the central controller on the central control connecting frame, and the electromagnetic sliding block is slid to move the left flip vibration sleeve and the right flip vibration sleeve connected to the rotating support arm, and finally the tube body of the dialyzer is fitted and surrounded. When the left semicircular limiting fixing plate and the right semicircular limiting fixing plate are close to fitting, the fixed buckle groove and the fixed buckle head are locked and fixed to complete the overall fixation of the dialyzer, and then the venous pot defoamer is aligned with the venous pot, and then the venous pot is inserted into the venous pot fixing sleeve, and at the same time, the bubble suction insertion needle is inserted into the inside of the venous pot to contact the surface layer where blood foam is generated.

[0035] After the initial assembly and fixation are completed, when working, the central controller controls the ultrasonic bubble detector to detect in real time whether there are bubbles in the dialyzer tube and controls the ultrasonic bubble detector to sense whether there are bubbles in the venous pot. After the bubbles are detected, the central controller controls the left flip vibration sleeve and the right flip vibration sleeve to vibrate at the same time, that is, by rotating the vibration arm, the vibration generator is attached to the surface of the dialyzer tube body for fixed vibration, so that the bubbles on the inner wall of the tube are vibrated off from the inner wall. When the bubbles are detected to be non-existent, it proves that the bubbles are basically vibrated off. At this time, the central controller controls the rotating support arm to drive the left flip vibration sleeve and the right flip vibration sleeve to rotate at the same time, so that the positions of the arterial inlet and venous outlet of the dialyzer are reversed, so that the air gathered by the bubbles can quickly enter one end of the venous outlet, and then quickly enter the venous pot to be discharged. Of course, the dialyzer can also be flipped at the beginning, and then the bubble overflow operation can be performed. When the bubbles are vibrated and overflow and finally reach the intravenous pot, the ultrasonic bubble detector of the intravenous pot detects the bubbles and air in the blood foam and controls the suction motor connected to the bubble insertion needle through the central controller to suck the blood foam and air, and send the extracted gas and blood foam to the waste liquid storage tube, thereby completing the elimination of bubbles.

[0036] During the entire process, the constant temperature heating strip continuously heats the blood in the dialyzer tube to prevent the blood temperature from dropping.

[0037] In this embodiment, flexible pads are fixedly provided on the inner sides of the left flip vibration sleeve and the right flip vibration sleeve to prevent the dialyzer tube from being damaged by excessive force during operation.

[0038] In this embodiment, the waste liquid storage tube is assembled on the central connecting block by means of a threaded engagement connection, which is conducive to quick disassembly and replacement of a new waste liquid storage tube for use.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
