Description

Technical Field

[0001] The invention mainly relates to the technical field of perfusion flushing devices, in particular to a perfusion flushing device. Background Art

[0002] Postoperative cleaning usually uses a flushing and suction gun to pour flushing fluid into the surgical site for cleaning, and then the contaminated flushing fluid is sucked out with an aspirator. The flushing fluid used during surgery is either at room temperature or bagged flushing fluid taken out of a constant temperature box.

When in use, the flushing liquid in the flushing liquid bag 44 can flow into the water inlet passage 13 through the second hose 43, and then into the liquid storage capsule 5.

[0040] Specifically, the liquid outlet passage 29 is connected to the external negative pressure pump 46 through the third hose 45. When liquid suction is required, the negative pressure pump 46 works and is connected to the liquid outlet passage 29 through the third hose 45, so that under the adsorption of negative pressure, the liquid enters the liquid suction valve body 25 through the liquid suction hose 42 and flows out from the liquid outlet passage 29, completing the liquid suction.

[0041] Specifically, a pull rod 47 is installed at one end of the connecting block 27, and a handle 48 is installed on the pull rod 47. Through the handle 48, the connecting block 27 can be pulled to separate the sealing gasket 38 from the liquid outlet passage 29, thereby allowing liquid to be sucked.

[0042] Specifically, two first slots 49 are provided at the bottom of the flushing gun 2, and the first hose 39 and the third hose 45 are respectively passed through the corresponding first slots 49. By providing the first slots 49, it is convenient for the first hose 39 and the second hose 45 to extend from the flushing gun 2; at the same time, the first slots 49 have a limiting effect on the first hose 39 and the second hose 45.

[0043] Specifically, a second slot 50 is provided on one side of the flushing gun 2, and the liquid suction hose 42 and the flushing pipe 41 are both passed out from the second slot 50. By providing the slot 50, it is convenient for the flushing pipe 41 and the liquid suction hose 42 to extend out from the flushing gun 2.

[0044] Specifically, a sealing limit sleeve 52 is provided on the outer side of the water outlet passage 14, a third through hole 53 is provided on one side of the sealing limit sleeve 52, a sixth passage 54 is installed on the upper part of the first passage 8, and the third through hole 53 is connected to the first passage 8 through the sixth passage 54. The sealing limit sleeve 51 can limit the outer end of the first hose 39, and at the same time, a gap cavity can be formed between the port of the first hose 39 and the water outlet passage 14, so that when the flushing operation is stopped (that is, when the first flushing passage 26 and the second flushing passage 27 are both closed), it is convenient for the liquid in the first hose 39 to flow back to the first passage 8 through the third through hole 53 and the sixth passage 54, so as to realize the sequential heating of the flushing liquid, thereby ensuring that there is no cold water in the flushing gun 2 during flushing, and hot water can always be guaranteed to be discharged immediately after it is turned on.

[0045] Specifically, a regulating knob 52 is provided on one side of the flushing valve body 23, and the regulating knob 52 is engaged with the sealing plug 30. The regulating knob 52 can control the flushing mode, the backwashing mode, and stop flushing, which brings convenience to the operator.

[0046] Working principle:

[0047] When the device is used and flushing is required, the adjusting knob 52 is rotated to rotate the sealing plug 30 with the adjusting knob 52, thereby connecting the second through hole 32 with the first flushing passage 26 (such as Fig. 9As shown), the flushing liquid in the flushing liquid bag 44 enters the water inlet passage 13 through the second hose 43, enters the first passage 8 through the water inlet passage 13, and then enters the first connecting pipe 18, thereby entering the heating pipe 6, and after being heated by the heating pipe 6, enters the second connecting pipe 19, enters the second passage 9 through the second connecting pipe 19, and enters the third passage 10 through the first opening 20 below, and then enters the fourth passage 11 through the second opening 21, and then enters the water pump 17 through the water outlet pipe 15, and passes through the water pump 17 is pumped into the water inlet pipe 16, enters the fifth passage 12 through the water inlet pipe 16, then enters the water outlet passage 14 through the fifth passage 12, and flows out through the water outlet passage 14, thereby reducing the temperature of the liquid after multiple flows inside the housing 1, avoiding excessive temperature and causing influence on the patient, and then enters the liquid inlet passage 34 through the first hose 39, and then enters the first flushing channel 26, thereby flowing out from the flushing pipe 41, and then flushing, the flushing liquid has temperature during the flushing process, avoiding excessive low temperature and causing discomfort to the patient;

[0048] After the flushing is completed or during the flushing process, when liquid needs to be sucked, the handle 48 is grasped to move the connecting block 37 outward, thereby driving the sealing gasket 38 to move, and the sealing gasket 38 is separated from the liquid outlet passage 29, thereby making the liquid outlet passage 29 connected to the inside of the liquid outlet valve body 25, and then the negative pressure pump 46 works to generate negative pressure suction, which is connected to the liquid outlet passage 29 through the third hose 45, and is connected to the liquid suction hose 42 through the liquid suction circuit 35, so that the liquid is sucked out from the inner wall of the liquid suction hose 42, and then enters the third hose 45, thereby completing the liquid suction;

[0049] After the liquid is sucked, a large amount of blood clots will be generated during flushing, which may easily clog and contaminate the inner wall of the liquid suction hose. At this time, the adjusting knob 52 is rotated to drive the sealing plug 30 to rotate, thereby connecting the second through hole 32 with the second flushing passage 27 (such as Fig.15As shown), the flushing liquid in the flushing liquid bag 44 enters the bag water inlet passage 13 through the second hose 43, enters the first passage 8 through the water inlet passage 13, and then enters the first connecting pipe 18, thereby entering the heating pipe 6, and after being heated by the heating pipe 6, enters the second connecting pipe 19, enters the second passage 9 through the second connecting pipe 19, and enters the third passage 10 through the first opening 20 below, and then enters the fourth passage 11 through the second opening 21, and then enters the water pump 17 through the water outlet pipe 15, and is pumped into the water inlet pipe 16 through the water pump 17, and then passes through the water inlet pipe 16. It enters the fifth passage 12, then enters the water outlet passage 14 through the fifth passage 12, and flows out through the water outlet passage 14, thereby reducing the temperature of the liquid after multiple flows inside the shell 1, avoiding excessive temperature and affecting the patient, and then enters the liquid inlet passage 34 through the first hose 39, and then enters the second flushing channel 27, and then enters the suction circuit 35 through the second flushing channel 27, thereby flowing out from the suction hose 42, and then flushing the inner wall of the suction hose to complete backwashing. During the backwashing process, the flushing liquid has a temperature, avoiding excessively low temperature and causing discomfort to the patient.

[0050] The present invention can heat the flushing liquid by arranging a heating tube, thereby ensuring the temperature of the flushing liquid and avoiding the flushing liquid temperature being too low, which causes discomfort to the patient; at the same time, by arranging multiple passages in the liquid storage bag, the flushing liquid can flow multiple times in the liquid storage bag, thereby reducing the temperature of the heated flushing liquid when it flows out, avoiding excessively high temperature and causing discomfort to the patient, thereby improving the patient's comfort; at the same time, through the cooperation of the flushing valve body and the suction valve body, multiple flushing modes of flushing and backwashing can be realized, and the same flushing and suction mode can be realized, thereby improving the applicability of the device.
