Description

Technical Field

[0001] The present invention relates to the technical field of blood purification, in particular to a blood purification machine with a heating function. Background Art

[0002] A blood purifier is a device that draws blood from a patient's body and directs it through a catheter into a blood purifier, where it filters and removes pathogenic substances from the blood, thereby purifying the blood. Blood purification, commonly known as dialysis, is a primary treatment for renal failure. To reduce treatment costs and simplify the process, simplified blood purification devices have been developed.

[0003] In the prior art, a Chinese patent with publication number "CN209204255U" discloses a blood purification device, which pulls out the tube plug, aligns the mouth of a test tube for sampling with the slot on the baffle and inserts it, moves the test tube upward, and drives the baffle upward through the test tube. After moving a certain distance, the fixing ring abuts against the mounting ring, and the mounting ring drives the connecting tube upward, so that the liquid guide channel and the sampling tube are connected. Blood can flow from the sampling tube into the test tube through the liquid guide channel, and the blood flowing into the blood purification device from the patient's body can be conveniently sampled and tested at any time to observe the purification efficiency of the blood in the patient's body. This solves the problem that the existing extraction method can only extract blood from the patient for sampling, and the patient will feel pain and discomfort during the blood extraction process.

[0004] Most existing blood purification devices use a filter and a heating rod or heating wire to filter and heat the extracted blood. However, during the filtering and heating process, since the filter is fixed, it relies solely on the blood's own flow pressure for filtration and cannot actively separate impurities adhering to the filter surface, easily forming a "filter cake effect". The "filter cake effect" seriously affects the filtering effect of the filter. At the same time, when the heating rod or heating wire is used to heat the blood, due to the high blood flow rate, it cannot flow in the pipe for a long time, so it cannot ensure that the blood is heated evenly.

[0018] The present invention provides a blood purification machine with a heating function. Compared with the prior art, it has the following advantages:

[0019] 1. The present invention utilizes a circulation pump to draw blood into the body through an arterial tube and an inhalation tube, and simultaneously starts a driving motor, which drives a driving disc to rotate. The T-shaped shaft on the driving disc drives a driving rod to rotate. Through the cooperation between the driving rod and the connecting rod, the limited sliding of the left slide groove and the left slider on the connecting rod, the limited sliding of the right slide groove and the right slider, and the limited position of the connecting rod by the positioning shaft, the left tooth plate on the left slider and the right tooth plate on the right slider are in a reciprocating and up-and-down state. The left tooth plate, the right tooth plate and the tooth block group on the arc frame plate cooperate to make the swing filter on the arc frame plate in a swinging state.

[0020] 2. In the present invention, when the curved frame plate swings, the toggle block on the curved frame plate moves synchronously. The reciprocating swing of the toggle block utilizes the reaction force of the upper and lower springs to repeatedly squeeze the floating frame plate, causing the adsorption net on the floating frame plate to reciprocate and rise. The reciprocating adsorption net is used to perform a secondary filtration on the filtered blood. At the same time, the vibration function of the upper and lower springs is used to prevent blood cells from depositing on the surface of the adsorption net, further improving the purification effect of the blood purification machine.

[0021] 3. In the present invention, when the filtered blood enters the heating box through the connecting tube, the blood in the heating box will pass through the cooperation of the upper and lower partitions, thereby extending the flow time of the blood in the heating box, and at the same time, the heating rod and the extension rod are used to heat the blood;

In the present invention, when the right tooth plate is lifted and lowered back and forth, it will synchronously drive the L-shaped connecting plate, and the L-shaped connecting plate will synchronously drive the lifting plate when it is lifted and lowered back and forth. The spiral rod on the lifting plate will adjust its position as the spiral rod rotates through the action of the bearing and the cooperation between the spiral rod and the U-shaped fixed plate, thereby effectively improving the heating effect of the blood purification machine.

[0040] In this embodiment, when the filtered blood enters the heating box 8 through the connecting tube 9, the blood in the heating box 8 will pass through the cooperation of the upper partition 49 and the lower partition 50, thereby extending the flow time of the blood in the heating box 8.

[0041] Working principle:

[0042] During use, the circulation pump 3 is used to draw blood into the body 1 through the arterial tube 4 and the suction tube 5, and the drive motor 14 is started at the same time. The drive motor 14 drives the drive disc 15 to rotate, and the T-shaped shaft 16 on the drive disc 15 drives the drive rod 17 to rotate. Through the cooperation between the drive rod 17 and the connecting rod 18, the limited sliding of the left slide groove 19 and the left slider 24 on the connecting rod 18, the limited sliding of the right slide groove 20 and the right slider 25, and the limitation of the positioning shaft 23 on the connecting rod 18, the left tooth plate 27 on the left slider 24 and the right slider are moved. The right tooth plate 28 on the block 25 is in a reciprocating and up-and-down state, and the left tooth plate 27, the right tooth plate 28 cooperate with the tooth block group 33 on the arc frame plate 32, so that the swing filter 12 on the arc frame plate 32 is in a swinging state. The swinging filter 12 in the swinging state can effectively filter impurities in the blood. When the arc frame plate 32 is swinging, the toggle block 42 on the arc frame plate 32 will move synchronously. The reciprocating swing of the toggle block 42 will utilize the reaction force of the upper spring 40 and the lower spring 41 to repeatedly squeeze The floating frame 39 makes the adsorption net 13 on the floating frame 39 in a reciprocating lifting process, and uses the reciprocating lifting adsorption net 13 to perform secondary filtration on the filtered blood. At the same time, the vibration function of the upper spring 40 and the lower spring 41 is used to prevent blood cells from depositing on the surface of the adsorption net 13. When the filtered blood enters the heating box 8 through the connecting tube 9, the blood in the heating box 8 will pass through the cooperation of the upper partition 49 and the lower partition 50, thereby extending the flow time of the blood in the heating box 8. At the same time, the heating rod 10 and the extension rod 11 are used to To complete the heating of the blood, when the right tooth plate 28 is lifted and lowered back and forth, it will synchronously drive the L-shaped connecting plate 44, and the L-shaped connecting plate 44 will synchronously drive the lifting plate 45 when it is lifted and lowered back and forth. The screw rod 47 on the lifting plate 45 will, through the action of the bearing 46 and the cooperation of the screw rod 47 and the U-shaped fixed plate 48, make the heating rod 10 and the extension rod 11 in the heating box 8 follow the screw rod 47 and adjust their positions during rotation, thereby effectively improving the heating effect of the blood purification machine. The heated blood will re-enter the human body through the venous tube 51.
