Description

Technical Field

[0001] The invention relates to the technical field of medical care, and specifically provides a postoperative wound irrigator and a use method thereof. Background Art

[0002] After a patient undergoes a surgical operation, the wound will be assisted to heal by sutures. The wound will go through necrosis, exudation of secretions and healing stages. In the early stage of wound recovery, the wound and its interior need to be flushed and cleaned to avoid wound inflammation and accelerate healing. However, existing flushing equipment can only directly flush unsutured wounds before or during surgery. For wounds that have been sutured after surgery, it is impossible to cut the sutures for conventional flushing, so the existing equipment can only flush the surface of the wound, and cannot effectively clean the inside of the wound. Due to the lack of equipment specifically for this situation, medical staff currently usually use a temporary combination of a syringe and a scalp needle hose for flushing: physiological saline or other sterile flushing fluid is injected into the wound through the scalp needle hose for multiple times to flush the wound, and the injected flushing fluid cannot be well sucked out after the flushing is completed, and this method requires multiple medical staff to cooperate in flushing. It can be seen that the existing flushing method has low flushing efficiency and high labor intensity, and it is also very easy to dirty the patient's clothes. Medical staff are also easily exposed to sewage, and there is a certain risk of infection. Therefore, there is an urgent need for a device that can effectively clean postoperative wounds in surgical operations. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a wound irrigator and a use method which can efficiently irrigate the wound of a patient after surgery.

[0004] The technical solution of the present invention is as follows:

[0005] A postoperative wound irrigator comprises a liquid storage box, an irrigating probe and an absorption tube, wherein the liquid storage box comprises an irrigating liquid storage tank and a waste liquid recovery tank, wherein the irrigating liquid storage tank and the waste liquid recovery tank are respectively connected to the irrigating probe and the absorption tube, and further comprises a cannula fixing part, wherein the cannula fixing part can position the absorption tube and the irrigating probe, wherein the irrigating probe is inserted into the wound from one end of the wound, and the absorption tube is inserted into the wound from the other end of the wound, and when the irrigating probe outputs irrigating liquid, the absorption tube absorbs back the used irrigating liquid.

[0006] In this solution, different from the existing flushing methods and processes, the flushing probe that outputs clean flushing liquid and the absorption tube that draws away the wastewater after flushing are inserted into the wound at the same time and work synchronously, so that the flushing liquid flows in from one end and flows out from the other end, flowing in the wound, thereby completing the wound flushing quickly and efficiently. At the same time, the wound secretion can be directly absorbed by the absorption tube, avoiding the accumulation of flushing liquid, improving the flushing effect, reducing leakage, and will not dirty the patient's clothes. It can also avoid direct contact between nursing staff and the wastewater after flushing, reducing safety risks. In addition, only one nursing staff is required for wound flushing through this device, which reduces manpower waste and reduces the labor intensity of nursing staff.

[0007] Preferably, the flushing probe comprises an insertion hose and a first connecting pipe which are interconnected, the insertion hose is inserted into the wound, a plurality of openings are evenly arranged at the end of the insertion hose, and the first connecting pipe is connected to the flushing liquid storage tank. Different from the existing method of using a hose or a syringe to output the flushing liquid from one outlet, in this scheme, the flushing liquid is output from multiple openings, and the flushing range is wider. At the same time, the diameter of the opening is the same as that of the insertion hose, ensuring that the total amount of flushing liquid output remains unchanged, while reducing the pressure of the flushing liquid output from a single outlet, making the water flow softer and avoiding damage to the wound.

[0008] In order to reduce the secondary damage to the patient caused by the flushing probe when it is inserted into the wound, the insertion hose has a certain flexibility. For wounds with a deeper depth and a longer length, the softer insertion hose cannot be inserted into the wound well. Preferably, a transition tube is also provided between the insertion hose and the connecting tube. The transition tube is provided with a guide wire insertion end. The guide wire can be inserted into the insertion hose from the guide wire insertion end. The opening of the insertion hose is provided on the side wall of the insertion hose. The insertion of the insertion hose is guided by the guide wire to avoid the problem that the insertion hose cannot be inserted into the wound due to bending due to force. In order to avoid the guide wire extending from the opening of the insertion hose, causing secondary damage to the patient, the end of the insertion hose is a hard tip. After the guide wire extends into the end of the insertion hose, it can abut against the end face of the insertion hose and will not leak out of the insertion hose. At the same time, the hard tip also makes it easier for the flushing probe to be inserted into the wound.

[0009] In order to solve the problem that the absorption tube is easily blocked by the wound tissue during the process of inserting the absorption tube into the wound to absorb the flushing liquid, preferably, the absorption tube includes an absorption head and a second connecting tube, the second connecting tube is connected to the waste liquid recovery tank, the end of the absorption head is connected to an ellipsoidal mesh cover, the surface of the ellipsoidal mesh cover is provided with a protrusion, and the outer cover of the absorption head is provided with a leakproof cover. The ellipsoidal mesh cover at the end of the absorption head can allow the absorption head to be better inserted into the wound through the arc end, reducing the secondary damage to the wound, and the ellipsoidal mesh cover has a larger adsorption area, and the multi-mesh structure can effectively prevent the wound tissue from blocking the absorption port of the absorption tube, and the protrusion on the surface of the ellipsoidal mesh cover can also allow the wound tissue to be adsorbed on the surface of the ellipsoidal mesh cover. There can be a certain gap between the protrusions of the ellipsoidal mesh cover, so as not to block the entire ellipsoidal mesh cover. And the target wound position is enclosed by the leakproof cover, which can avoid the problem of the flushing liquid leaking from the absorption tube insertion position due to the too fast input of the flushing liquid.

[0010] Preferably, the cannula fixing portion comprises an insertion fixing unit and a suction-back fixing unit, and a water-absorbent dressing is arranged between the insertion fixing unit and the suction-back fixing unit.

[0011] In this solution, since the postoperative wound is generally long and narrow, the insertion fixing unit and the suction fixing unit are set in direct contact with the patient's skin to provide an installation and positioning basis for the flushing probe and the absorption tube. The absorbent dressing can absorb the flushing fluid seeping from the middle of the wound during the flushing process, and can also perform the absorbent dressing operation more quickly and conveniently after the flushing is completed.

[0012] Preferably, the insertion fixing unit is a U-shaped structure with a groove facing the suction fixing unit, and the flushing probe can be inserted into the wound from the groove of the insertion fixing unit. A positioning clamp is provided on the groove wall of the insertion fixing unit for clamping and positioning the flushing probe, and the surface of the insertion fixing unit is inclined downward in the direction away from the suction fixing unit.

[0013] In this solution, the positioning clamp can clamp the flushing probe after it is inserted into the wound, replacing the medical staff in supporting the flushing probe and preventing it from falling out of the wound. At the same time, the surface of the fixing unit is tilted, making it easier for the medical staff to insert the insertion hose into the wound at an angle, avoiding interference between the insertion fixing unit and the flushing probe.

[0014] Preferably, the suction fixing unit is a U-shaped knot with a groove facing the insertion fixing unit, and the absorption tube can be inserted into the wound from the groove of the suction fixing unit. The positioning fixture is provided on the groove wall of the suction fixing unit for clamping and positioning the absorption tube. Similar to the insertion fixing unit, the positioning fixture on the suction fixing unit can clamp the absorption tube after the absorption tube is inserted into the wound, replacing the medical staff to support the absorption tube and preventing the absorption tube from falling out of the wound.

[0015] Preferably, the positioning fixture includes an elastic connecting rod which is symmetrically and rotatably arranged on the groove wall of the groove, and the elastic connecting rod is in a compressed state when clamped. A clamp is provided at the end of the elastic connecting rod to ensure that the flushing probe and the absorption tube can be corrected to a certain extent in angle according to wounds at different positions on the bodies of different patients, thereby improving adaptability and reducing the difficulty of inserting the flushing probe and the absorption tube into the wound.

[0016] In order to solve the problem of more accurately locating the wound insertion point to improve the flushing effect, the cannula fixing part further includes a connecting guide rail, and tightening belts are provided at both ends of the connecting guide rail. The insertion fixing unit and the suction fixing unit are slidably arranged on the connecting guide rail, and a positioning structure is provided on the insertion fixing unit and the suction fixing unit.

[0017] In this solution, the cannula fixing part can be set at the target position through two tightening bands according to the wound size of different patients, and the distance between the fixing unit and the suction fixing unit can be adjusted by sliding the fixing unit for insertion and the suction fixing unit in combination with the actual wound suturing situation to determine the most suitable wound insertion point. Moreover, the sliding insertion fixing unit and the suction fixing unit can also move away from each other after the tightening bands are fixed to make way for the insertion of the flushing probe and the absorption tube, so that medical staff can better insert the flushing probe or the absorption tube into the target position of the wound.

[0018] The cannula fixing part is made of transparent material, which is convenient for medical staff to directly observe the flushing situation through the transparent cannula fixing part when flushing the wound of the patient.

[0019] A flexible waterproof pad is arranged at the bottom of the insertion fixing unit and the suction-back fixing unit. The flexible waterproof pad can make the insertion fixing unit and the suction-back fixing unit better fit the skin through its own elasticity. There is a water-absorbing dressing between the insertion fixing unit and the suction-back fixing unit to absorb the seeped water. The flexible waterproof pad can also prevent the flushing liquid from seeping out from both ends.

[0020] A method for using a postoperative wound irrigator, using the above-mentioned postoperative wound irrigator, includes step S1. arranging a suction fixing unit and an insertion fixing unit at two ends of a target length direction respectively.

[0021] S2. Insert the flushing probe into the target and fix it at the insertion fixing unit, and insert the absorption tube into the target and fix it at the suction fixing unit;

[0022] S3. The flushing cannula outputs the flushing liquid, and the absorption tube washes the hand washing flushing liquid for 3 to 10 minutes. In this step, by allowing the flushing liquid to flow in the wound, the flushing liquid has a better flushing effect, which greatly reduces the flushing time and improves the flushing efficiency compared with the existing flushing method.

[0023] S4. Remove the irrigation cannula and absorption tube, and apply the absorbent dressing completely to the wound.

[0024] In this step, by setting the absorbent dressing between the suction fixing unit and the insertion fixing unit in advance, it is convenient for single-person operation by medical staff. When the flushing probe is pulled out, the absorbent dressing can immediately cover the position where the flushing probe is inserted into the wound, and absorb the residual liquid. Pressing the absorbent dressing toward the position of the suction fixing unit along the target length direction can squeeze the residual flushing liquid in the wound out of the wound and reduce the residual liquid. At the same time, when the absorption tube is pulled out, the absorbent dressing can immediately cover the position where the absorption tube is inserted into the wound to absorb the residual liquid in the leak-proof cover. The arrangement of the absorbent dressing is completed in the process of pulling out the absorption tube and the flushing probe, which is efficient and quick.

[0025] S5. Remove the cannula fixing part and fix the absorbent dressing to complete the cleaning.

[0026] Beneficial effects of the present invention:

[0027] 1. The present invention is different from the existing flushing methods and processes. The flushing probe for outputting clean flushing liquid and the absorption tube for extracting the sewage after flushing are inserted into the wound at the same time and work synchronously, so that the flushing liquid flows in from one end and flows out from the other end, flowing in the wound, thereby improving the flushing effect and the efficiency of the entire flushing.

[0028] 2. After the flushing liquid is output, it will be directly absorbed by the absorption tube. It will not accumulate in the wound, is not easy to leak, will not dirty the patient's clothes, and can prevent nursing staff from direct contact with the wastewater after flushing, reducing safety risks.

[0029] 3. The patient's wound is irrigated by this device. By utilizing the cooperation between the irrigating probe, the absorption tube and the cannula fixing part, the entire irrigating process can be completed by only one nurse, which reduces manpower waste and also reduces the labor intensity of the nurse.

DETAILED DESCRIPTION

[0039] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through the specific implementation methods of the embodiments of the present invention.

[0040] Embodiment 1:

[0041] A postoperative wound irrigator, such as Figure 1 and Figure 2 As shown, it includes a liquid storage tank 1, a flushing probe 2 and an absorption tube 3. The liquid storage tank 1 includes a flushing liquid storage tank 11 and a waste liquid recovery tank 12, and is connected to the flushing probe 2 and the absorption tube 3 respectively. It also includes a cannula fixing part 4, and the cannula fixing part 4 can position the absorption tube 3 and the flushing probe 2. The flushing probe 2 is inserted into the wound from one end of the wound, and the absorption tube 3 is inserted from the other end of the wound. When the flushing probe 2 outputs the flushing liquid, the absorption tube 3 sucks back the used flushing liquid. The specific liquid storage tank 1 is respectively provided with two pump structures, one pump controls the pressure of the flushing liquid output by the flushing liquid storage tank 11, and the other pump controls the suction force of the absorption tube 3. The cannula fixing part 4 can be a structure that can be set on the skin surface at the wound, and can provide fixation for the flushing probe 2 and the absorption tube 3 through the clamping and adsorption principles, so that medical staff do not need to hold the flushing probe 2 or the absorption tube 3 all the time.

[0042] In order to ensure the overall flushing effect of the flusher, the flushing probe 2 further includes an insertion hose 21 and a first connecting pipe 22 that are interconnected. The insertion hose 21 is inserted into the wound, and a plurality of openings 23 are evenly arranged at the end of the insertion hose 21. The first connecting pipe 22 is connected to the flushing liquid storage tank 11. The flushing liquid is output from the plurality of openings 23, and the flushing range is wider. It should be noted that the diameter of the opening 23 is the same as that of the insertion hose 21, and the total amount of flushing liquid output is ensured to remain unchanged, and the pressure of the flushing liquid output from a single outlet is reduced, so that the water flow is softer and the wound is prevented from being damaged.

[0043] Since the insertion hose 21 has a certain degree of flexibility, the insertion hose 21 cannot be inserted well into the wound if the wound is deep and long. Figure 2 As shown, a transition tube 24 is further provided between the insertion hose 21 and the connecting tube, and a guide wire insertion end 26 is provided on the transition tube 24. The guide wire 25 can be inserted into the insertion hose 21 from the guide wire insertion end 26. The opening 23 of the insertion hose 21 is provided on the side wall of the insertion hose 21. The insertion of the insertion hose 21 is guided by the guide wire 25 to avoid the problem that the insertion hose 21 is bent by force and cannot be inserted into the wound. In order to avoid the guide wire 25 extending from the opening 23 of the insertion hose 21, causing secondary injury to the patient, the end of the insertion hose 21 is a hard tip 27. After the guide wire extends into the end of the insertion hose 21, it can abut against the end surface of the insertion hose 21 and will not leak out of the insertion hose 21. In addition, a socket for inserting the guide wire 25 can also be provided at the end of the insertion hose 21, so that the end of the guide wire 25 is connected to the end of the insertion hose 21, and the guide wire 25 continues to extend toward the end to abut against the end of the insertion hose 21, and is limited by the socket when it deviates radially.

[0044] It should be noted that the length of the insertion hose 21 and the number of openings 23 need to be set according to the actual length and depth of the patient's wound, and after the insertion hose 21 is extended to the predetermined position, the guide wire 25 needs to be retracted and the guide wire insertion end 26 needs to be blocked.

[0045] Further, such as Figure 5 As shown, the absorption tube 3 generates suction to absorb the flushing liquid after cleaning. After the absorption tube 3 is inserted into the wound, in order to avoid damaging the wound, its suction force cannot be too large, and the opening 23 of the absorption tube 3 is easily blocked by the wound tissue, etc., and the absorption tube 3 is squeezed out by the pressure due to the output rate of the flushing liquid, resulting in sewage leakage. Therefore, for this reason, Figure 2As shown, the absorption tube 3 includes an absorption head 31 and a second connecting tube 32. The outer cover of the absorption head 31 is provided with a leak-proof cover 33. The end of the absorption head 31 is provided with an ellipsoidal mesh cover 34. The surface of the ellipsoidal mesh cover 34 has many small holes and arc-shaped protrusions. Even if wound tissue is adsorbed, the ellipsoidal mesh cover 34 has grid holes from all directions. The grid holes that are not blocked by the wound tissue can continue to allow the flushing liquid to be sucked into the absorption head 31. At the same time, due to the existence of the arc-shaped protrusions, after the wound tissue is adsorbed on the ellipsoidal mesh cover 34, gaps will be generated between the arc-shaped protrusions to ensure that the wound tissue will not block the ellipsoidal mesh cover 34, and the target position is enclosed by the leak-proof cover 33 to reduce the occurrence of flushing liquid leakage.

[0046] Furthermore, the absorption head 31 is slidably inserted into the port of the second connecting tube 32 through the elastic unit 35. Even if the absorption head 31 is still blocked and the pressure at the wound is too high, the absorption head 31 will slide upward and release the pressure due to the elastic unit 35 under the pressure of the liquid in the wound, and the adsorption blockage of the wound tissue can be released by moving, and liquid leakage can be prevented in cooperation with the leak-proof cover 33. At this time, the absorption tube 3 can be allowed to be shallowly inserted into the wound so that the entire wound can be cleaned, avoiding the formation of a dead zone in the part where the absorption tube 3 is inserted into the wound due to the insertion of the absorption tube 3 into the wound.

[0047] The flushing process of using this flusher is different from the existing flushing method and flushing process. The flushing probe 2 that outputs clean flushing liquid and the absorption tube 3 that draws away the sewage after flushing are inserted into the wound at the same time and work at the same time, allowing the flushing liquid to flow in from one end and then output from the other end. The flushing liquid flows in the wound, and can quickly and efficiently complete the flushing of the wound. At the same time, the wound secretes liquid that can be directly sucked away by the absorption tube 3. There will be no accumulation of flushing liquid. The flushing effect is better, and it is not easy to leak out, and it will not dirty the patient's clothes. It can also avoid direct contact between nursing staff and sewage after flushing, reducing safety risks.

[0048] Embodiment 2:

[0049] On the basis of the first embodiment, this embodiment provides a specific structure of the cannula fixing part 4, such as Figures 2 to 6As shown, the cannula fixing part 4 includes an insertion fixing unit 41 and a suction fixing unit 42. The insertion fixing unit 41 and the suction fixing unit 42 are U-shaped structures with two grooves facing opposite directions. The flushing probe 2 and the absorption tube 3 can be inserted into the wound from the grooves, and the groove walls of the grooves are provided with positioning fixtures for clamping and positioning the flushing probe 2 and the absorption tube 3. The surface of the insertion fixing unit 41 is tilted downward in the direction away from the suction fixing unit 42, which is convenient for medical staff to tilt the insertion hose 21 into the wound and avoid interference between the insertion fixing unit 41 and the flushing probe 2. The positioning fixture on the suction fixing unit 42 can clamp the absorption tube 3 after the absorption tube 3 is inserted into the wound, replacing the medical staff to support the absorption tube 3 and prevent the absorption tube 3 from falling out of the wound.

[0050] Further, the positioning fixture includes an elastic link 44 symmetrically and rotationally arranged on the groove wall of the slot, the elastic link 44 is in a compressed state when clamped, a clamp 45 is arranged at the end of the elastic link 44, and a locking structure is arranged at the rotation connection between the elastic link 44 and the slot, the locking structure includes but is not limited to a gear structure on the elastic link 44, and the elastic link 44 is prevented from rotating by a locking tooth that can be pressed externally; or the elastic link 44 is passed through the cannula fixing part 4, and a thread is arranged on the elastic link 44, and a nut is arranged, and the elastic link 44 is tightened by tightening the nut to prevent the rotation of the clamp 45, etc. The clamp 45 can rotate, ensuring that the flushing probe 2 and the absorption tube 3 can be corrected to a certain extent according to the wounds at different positions on the body of different patients, improving adaptability, and reducing the difficulty of inserting the flushing probe 2 and the absorption tube 3 into the wound.

[0051] It should be noted that in the flushing probe 2, the transition tube 24 has higher strength than the insertion hose 21. The positioning fixture clamps the transition tube 24 of the flushing probe 2 to prevent the flushing probe 2 from deforming due to excessive clamping force, thereby affecting the output of the flushing liquid.

[0052] Furthermore, in order to prevent the insertion of the flushing probe 2 and the absorption tube 3 from being hindered by the insertion of the cannula fixing portion 4 on the skin. Figure 2 , Figure 3 and Figure 6 As shown, the cannula fixing part 4 also includes a connecting rail 51, and tightening belts 5 are arranged at both ends of the connecting rail 51. The insertion fixing unit 41 and the suction fixing unit 42 are slidably arranged on the connecting rail 51. The insertion fixing unit 41 and the suction fixing unit 42 are provided with a positioning structure, and the positioning structure includes a limit bolt. By rotating the limit bolt, the limit bolt is squeezed and rubbed on the connecting rail 51 to prevent the insertion fixing unit 41 and the suction fixing unit 42 from sliding on the connecting rail 51, so as to achieve positioning. Figure 6As shown, the connecting guide rail 51 includes two symmetrically arranged guide rails, the outer side of the two guide rails is connected with a tightening belt 5, and the water-absorbing dressing 43 is arranged between the two guide rails. The cannula fixing part 4 is provided with a sliding hole corresponding to the guide rail, and the outer side of the sliding hole is provided with a slot for the tightening belt to extend out. The insertion fixing unit 41 and the suction fixing unit 42 can slide on the connecting guide rail 51, and then the cannula fixing part 4 can be set at the target position through the two tightening belts 5 according to the wound size of different patients, and the distance between the two can be adjusted by sliding the insertion fixing unit 41 and the suction fixing unit 42 in combination with the actual wound suturing situation to determine the most suitable wound insertion point, and the sliding insertion fixing unit 41 and the suction fixing unit 42 can also move away from each other after the tightening belt 5 is fixed, so as to make way for the insertion of the flushing probe 2 and the absorption tube 3, so that medical staff can better insert the flushing probe 2 or the absorption tube 3 into the target position of the wound.

[0053] Furthermore, the cannula fixing part 4 is made of transparent material, so that medical staff can directly observe the flushing situation through the transparent cannula fixing part 4 when flushing the wound of the patient. The material is preferably medical transparent materials such as ABS and PVC.

[0054] A flexible waterproof pad 46, such as a TPE waterproof pad, is arranged at the bottom of the insertion fixing unit 41 and the suction fixing unit 42. The flexible waterproof pad 46 can make the insertion fixing unit 41 and the suction fixing unit 42 better fit the skin through its own elasticity. There is a water-absorbing dressing 43 between the insertion fixing unit 41 and the suction fixing unit 42 to absorb the seeped water. The flexible waterproof pad 46 can also prevent the flushing liquid from seeping out from both ends.

[0055] Embodiment three:

[0056] Based on the above embodiments, Figure 2 and Figure 3 As shown, due to the different wound lengths of different patients, the spacing between the insertion fixing unit 41 and the suction fixing unit 42 is not fixed, and the insertion fixing unit 41 and the suction fixing unit 42 can be connected by an elastic drawstring; the insertion fixing unit 41 and the suction fixing unit 42 are connected by a sliding telescopic structure, such as the flexible ratchet bar structure in this embodiment, that is, one of the insertion fixing unit 41 and the suction fixing unit 42 is connected to the ratchet bar, and the other is provided with a ratchet structure matching the ratchet bar, so that medical staff do not need to separately install or disassemble the insertion fixing unit 41 or the suction fixing unit 42 when using the present invention alone, ensuring that the other end will not fall when operating one end; of course, the insertion fixing unit 41 and the suction fixing unit 42 can also be directly two separate parts. Therefore, a water-absorbing dressing 43 is set between the insertion fixing unit 41 and the suction fixing unit 42, and the water-absorbing dressing 43 can use traditional gauze, a new foam rectangular water-absorbing dressing 43, etc.

[0057] Furthermore, a connecting roller 47 is respectively provided at the ends adjacent to the insertion fixing unit 41 and the suction fixing unit 42, and a support rod is provided on the side of the insertion fixing unit 41 and the suction fixing unit 42 to be inclined upward, and an end rod 49 is provided on the support rod parallel to the connecting roller 47. The medicine surface of the long strip of absorbent dressing 43 faces downward, and the two ends are respectively passed around the bottom of the two connecting rollers 47 and temporarily adhered to the end rod 49 by medical tape, and the absorbent dressing 43 is in a relaxed state.

[0058] Specifically, since the postoperative wound is generally long and narrow, by setting the insertion fixing unit 41 and the suction fixing unit 42 in direct contact with the patient's skin, a foundation for installation and positioning is provided for the flushing probe 2 and the absorption tube 3. The water-absorbing dressing 43 can absorb the flushing liquid exuded from the middle of the wound during the flushing process, and can also be operated more quickly and conveniently after the flushing is completed. After the flushing is completed, when it is necessary to pull out the flushing probe 2 or the absorption tube 3, if it is necessary to pull out the flushing probe 2, first pull out the flushing probe 2, and since the tightening belt 5 is fixed, then slide the insertion fixing unit 41 to move the insertion fixing unit 41 away from the insertion tube fixing part 4, and at the same time contact the water-absorbing dressing 43 on the corresponding end rod 49. As the insertion fixing unit 41 moves, the connecting roller 47 can automatically apply the water-absorbing dressing 43 to the position where the flushing probe 2 is pulled out, which is efficient and fast. The same is true for the absorption tube 3.

[0059] Embodiment 4:

[0060] A method for using a postoperative wound irrigator, in combination with the postoperative wound irrigator in the above embodiment, comprises the following steps:

[0061] S1. The suction fixing unit 42 and the insertion fixing unit 41 are respectively arranged at two ends of the target (wound) along the length direction.

[0062] Specifically, the wound surface is first disinfected, and then the tightening belt 5 is tightened to position the suction fixing unit 42 and the insertion fixing unit 41 at the target position, so that the entire wound is in the distance between the two. At this time, the tightening belt 5 has been fixed on the patient's body, and the suction fixing unit 42 and the insertion fixing unit 41 are slid to the position where they are farthest apart by connecting the guide rails 51.

[0063] S2. Insert the flushing probe 2 into the target position and fix it at the insertion and fixing unit 41, and insert the absorption tube 3 into the target and fix it at the suction and fixing unit 42.

[0064] Specifically, the flushing probe 2 is inserted into the target at the notch of the insertion fixing unit 41 and the flushing probe 2 and the insertion fixing unit 41 are fixed, so that the flushing probe 2 first outputs a small amount of flushing liquid from one end, and the situation is observed. Specifically, the insertion hose 21 is inserted into the wound from one end through the guide wire 25, and 10-100 ml of flushing liquid is first injected according to the size of the wound to observe whether the flushing liquid leaks from the middle of the wound.

[0065] When leakage occurs from the middle of the wound in S2, the absorbent tube 3 can be inserted into the wound from the leaking point. If there is no leakage, it can be inserted from the other end of the wound. Then the long strip of absorbent dressing 43 is placed with the medicine surface facing downward, and the two ends are respectively passed through the bottom of the two connecting rollers 47 and temporarily attached to the end rod 49 through medical tape. The absorbent dressing 43 is in a relaxed state, and the middle of the wound should be covered by the absorbent dressing 43 to avoid leakage in the middle.

[0066] S3. The flushing probe 2 outputs the flushing liquid from one end, and the absorption tube 3 absorbs the flushing liquid from the other end, and this lasts for 3 to 10 minutes. By allowing the flushing liquid to flow in the wound, the flushing liquid has a better flushing effect, and the entire flushing process is continuous, which greatly reduces the flushing time and improves the flushing efficiency compared to the existing flushing method.

[0067] S4. Pull out the flushing cannula and the absorption tube 3, and apply the absorbent dressing 43 completely to the wound.

[0068] Specifically, the flushing probe 2 stops outputting flushing liquid and is pulled out, the insertion fixing unit 41 is moved away from the suction fixing unit 42, one end of the absorbent dressing 43 leaves the end rod 49, and is unfolded under the drive of the connecting roller 47, so that one end of the absorbent dressing 43 covers the position where the flushing probe 2 was previously inserted into the target, during which the medical staff can use their fingers to assist in pressing the absorbent dressing 43; by setting the absorbent dressing 43 between the suction fixing unit 42 and the insertion fixing unit 41 in advance, it is convenient for the medical staff to operate it alone, and when the flushing probe 2 is pulled out, the absorbent dressing 43 can immediately cover the position where the flushing probe 2 is inserted into the wound, and absorb the residual liquid.

[0069] Then, the absorbent dressing 43 is pressed toward the position of the suction fixing unit 42 along the length direction of the wound, and the wound is gently pressed to roll the cleaning liquid in the wound toward the absorption tube 3, and then the suction fixing unit 42 is pulled outward, and the suction fixing unit 42 moves away from the insertion fixing unit 41. When the absorption tube 3 is pulled out, the other end of the absorbent dressing 43 covers the position where the absorption tube 3 was previously inserted into the target. In this step, pressing the absorbent dressing 43 toward the position of the suction fixing unit 42 along the target length direction can squeeze the residual flushing liquid in the wound out of the wound, reducing the residual liquid. At the same time, when the absorption tube 3 is pulled out, the absorbent dressing 43 can immediately cover the position where the absorption tube 3 is inserted into the wound, and absorb the residual liquid in the leakproof cover 33. The arrangement of the absorbent dressing 43 is completed in the process of pulling out the absorption tube 3 and the flushing probe 2, which is efficient and quick.

[0070] S5. After removing the cannula fixing part 4 and fixing the absorbent dressing 43, the cleaning is completed, and the inside of the wound is flushed without affecting the sutures of the wound.
