DETAILED DESCRIPTION

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0049] Reference Figure 1 - Figure 11, A wound irrigator, comprising an irrigation head 1, a hose 4 with its head and tail connected, a suction tube 2, and a soft apron 7; one end of the irrigation head 1 is provided with a plurality of liquid spraying holes, the other end of the irrigation head 1 is provided with a liquid supply tube 3 communicating with the liquid spraying holes, and the end of the liquid supply tube 3 is communicated with an external liquid pump; the hose 4 is connected with its head and tail, a plurality of suction covers 5 are arranged on the lower surface of the hose 4, each suction cover 5 is communicated with the inside of the hose 4, and a plurality of notches 6 are arranged on the edge of the cover body of the suction cover 5; one end of the suction tube 2 is communicated with the hose 4, and the other end of the suction tube 2 is communicated with an external negative pressure pump; the apron 7 is arranged annularly along the outer circle of the hose 4, and the lower edge of the apron 7 protrudes from the bottom of the hose 4; in this embodiment, the specific use method of the designed wound irrigator is as follows:

[0050] First, attach the hose 4 to the patient's body. The closed loop formed by the hose 4 surrounds the wound. Moreover, the hose 4 itself is plastic and can flexibly adjust the shape of the closed loop according to the shape of the wound and the specific position of the wound on the patient's body. Then, drive the external negative pressure pump to pump air. At this time, the soft suction cover 5 can be adsorbed on the patient's body. At the same time, the soft apron 7 is squeezed between the suction cover 5 and the patient's skin under the adsorption force, and the edge of the apron 7 also adheres to the patient's skin surface. At this time, the hose 4 cooperates with the apron 7 to surround the wound. Then, drive the external liquid pump. The external liquid pump injects the irrigation liquid into the irrigation head 1, and the irrigation liquid sprays on the wound. The irrigation liquid continuously flushes the wound, flushing off the scabs, pus, or foreign bodies at the wound, and at the same time disinfects the wound. The excess irrigation liquid will flow along the skin to the lower position of the closed loop formed by the hose 4. At this time, the inside of the suction cover 5 is in a negative pressure state. Since a plurality of notches 6 are arranged on the edge of the suction cover 5, the irrigation liquid will be adsorbed into the suction cover 5 along the notches 6 and be drawn away along the hose 4 and the suction tube 2. At the same time, the softened scabs, diluted pus, or foreign bodies will also be drawn away;

[0051] This wound irrigator surrounds the periphery of the wound in the way of a cofferdam to restrict the flow of the irrigation liquid and avoid pollution caused by the random flow of the irrigation liquid. At the same time, the plastic hose 4 can flexibly adjust the shape of the closed loop according to the specific shape and position of the wound, with high flexibility, adapting to the wound conditions of more parts of the patient's body. In addition, the suction cover 5 can not only adsorb and squeeze the hose 4 and the apron 7 on the patient's skin surface, but also draw away the excess irrigation liquid, avoiding the overflow of the continuously sprayed irrigation liquid from the closed loop formed by the hose 4, reducing the trouble of cleaning the irrigation liquid before removing the hose 4 later, facilitating the medical staff to flush and treat the patient's wound, reducing the execution actions that the patient needs to cooperate with when flushing the wound, and reducing the patient's pain.

[0052] Refer to Figure 1 - Figure 11, a transparent film 8 is provided on the upper surface of the hose 4. One edge of the transparent film 8 is arranged along the circumferential direction of the hose 4, and the other edge of the transparent film 8 is fixedly connected with a ring body 9. A flushing head 1 is installed on the ring body 9;

[0053] Yielding openings 10 are symmetrically formed in the inner ring of the ring body 9, and clamping openings 11 are symmetrically formed in the lower surface of the ring body 9;

[0054] The flushing head 1 includes a spray head 12, a pipe body 13 and a connecting head 14;

[0055] A plurality of liquid spraying holes are formed in the spray head 12, and the inside of the spray head 12 is communicated with the inside of the connecting head 14 through the pipe body 13;

[0056] The connecting head 14 includes a disk body 15. A rotating body 16 is arranged on the lower end surface of the disk body 15, and the pipe body 13 is fixedly connected to the lower end of the rotating body 16;

[0057] Clamping parts 17 are symmetrically arranged on the outer ring of the rotating body 16, a spring 18 is arranged above the clamping parts 17, and the spring 18 is sleeved on the rotating body 16;

[0058] For some wounds with severe scabbing or the problem that hospital cotton swabs adhere firmly, it is difficult to wash them off by spraying. It is also necessary to pressurize the flushing liquid to increase the impact force of the flushing liquid so as to quickly scab or wash off the cotton swab. However, the pressurized flushing liquid will cause splashing problems and pollute a larger area. Therefore, a transparent film 8 is arranged between the flushing head 1 and the hose 4. The transparent film 8 can block the splashing flushing liquid. At this time, medical staff can freely operate the spraying direction of the flushing liquid of the flushing head 1 without considering the problem that the flushing liquid will spray outside the transparent film 8, and the operation is more handy;

[0059] By setting the connection between the flushing head 1 and the transparent film 8 to be detachable, it is convenient to clean the transparent film 8 and the hose 4 and recycle them;

[0060] The flushing head 1 is installed on the ring body 9 as follows: Align the clamping part 17 with the yielding opening 10, press the rotating body 16, and after pressing the clamping part 17 below the ring body 9, rotate it by ninety degrees and then release the rotating body 16. At this time, the clamping part 17 is pressed by the elastic force of the spring 18, and the clamping part 17 is embedded in the clamping opening 11, and the rotating body 16 can be connected to the ring body 9. At this time, the operator holds the disk body 15, and can control the spraying direction of the flushing liquid of the spray head 12, and the transparent film 8 can clearly see the specific situation of the flushing liquid spraying.

[0061] Refer to Figure 1 - Figure 15 , two U-shaped holding parts 19 are symmetrically arranged on the outer ring of the ring body 9;

[0062] When medical staff operate the flushing head 1, the thumb and index finger are embedded in the hand-held part 19, which is convenient for grasping and controlling the flushing head 1. At the same time, because the fingers grasp it, the transparent film 8 will not be blocked, ensuring a clearer field of vision and facilitating observation of the specific situation of wound flushing.

[0063] Reference Figure 9 - Figure 15 A trigger structure for controlling the spraying of the flushing liquid is provided between the inside of the handheld portion 19 and the rotating body 16;

[0064] The trigger structure includes a push rod 20, which passes through a guide hole provided on the outer ring of the ring body 9. One end of the push rod 20 is connected to the outer ring of the ring body 9 through a return spring, and the other end of the push rod 20 points to the swivel 16 of the inner ring of the ring body 9.

[0065] A sliding hole 21 is radially defined inside the swivel 16. The sliding hole 21 is opposite to the other end of the push rod 20. A baffle 22 is sealingly and slidably connected in the sliding hole 21. The end of the baffle 22 away from the push rod 20 is connected to the bottom of the sliding hole 21 via a compression spring 23. A through hole 24 is defined on one side of the baffle 22. The other end of the baffle 22 is flush with the outer ring of the swivel 16.

[0066] When the baffle 22 is in the initial state, the through hole 24 on the baffle 22 is staggered with the tube body 13, and the baffle 22 blocks the inlet end of the tube body 13 and the outlet end of the liquid supply pipe 3;

[0067] The other end of the baffle 22 is flush with the outer ring of the swivel 16. After the swivel 16 is embedded in the ring body 9, the baffle 22 is prevented from being stuck on the ring body 9, ensuring that the swivel 16 can move freely within the inner ring of the ring body 9.

[0068] When the connector 14 is installed on the ring body 9, the baffle 22 is opposite to the push rod 20, and the medical staff's fingers are embedded in the hand-held part 19. When the shower head 12 needs to spray the flushing liquid, the fingers press the push rod 20 hard, the push rod 20 compresses the compression spring 23, and squeezes the baffle 22. The baffle 22 moves deep into the sliding hole 21. At the same time, the through hole 24 connects the inlet end of the tube body 13 and the outlet end of the liquid supply pipe 3, and the flushing liquid can be discharged from the shower head 12; when the flushing liquid is not needed, the fingers release the push rod 20, the baffle 22 returns to its initial state, and the shower head 12 stops spraying the flushing liquid. By setting the switch for controlling the spraying of the flushing liquid in the hand-held part 19, it is convenient for medical staff to control the spraying of the flushing liquid, and there is no need to control the switch of the spray head 12 with the other hand, which provides convenience for medical staff.

[0069] Reference Figure 9 - Figure 15 , a clamping plate 25 is radially provided on the outer ring of one end of the push rod 20;

[0070] An anti - detachment plate 26 is provided on the inner side wall of the handheld part 19, and the anti - detachment plate 26 is arranged close to the ring body 9;

[0071] When it is determined that the wound needs to be rinsed for a long time, after squeezing the ejector rod 20, rotate the ejector rod 20 to rotate the clamping plate 25 to the inside of the anti - detachment plate 26. At this time, the anti - detachment plate 26 fixes the position of the clamping plate 25 at this time, that is, fixes the position of the ejector rod 20 after being squeezed. The ejector rod 20 continuously presses against the baffle plate 22, and the spray head 12 continuously sprays the rinsing liquid. Medical staff do not need to squeeze the ejector rod 20 for a long time to avoid finger soreness.

[0072] Refer to Figure 1 - Figure 4 A mist pipe 27 is provided between the transparent film 8 and the hose 4. The mist pipe 27 is arranged with its head and tail connected in communication, and a plurality of micropores 28 are opened on the surface of the mist pipe 27. The direction of the rinsing liquid sprayed from each micropore 28 points to the middle position of the inner circle of the hose 4;

[0073] A branch pipe 29 is connected to the mist pipe 27, and the branch pipe 29 is connected to the liquid supply pipe 3;

[0074] For the situation of a large wound surface, as well as the problem of a large amount of foreign matters such as scabs on the wound edge and relatively firm attachment, it can be pre - softened by spraying atomized rinsing liquid through the mist pipe 27, by spraying a small amount of atomized rinsing liquid with a wide coverage area; a valve is provided on the branch pipe 29 to control the connection between the liquid supply pipe 3 and the branch pipe 29. When atomized spraying is required, the valve is opened, and the rinsing liquid flows into the mist pipe 27 along the branch pipe 29 and sprays the rinsing liquid from a plurality of micropores 28. The rinsing liquid pre - treats the wound. At this time, the spraying amount of the rinsing liquid is small and the wound coverage range is wide, which can both save the rinsing liquid and reduce the operation of medical staff. Medical staff only need to wait aside without any operation. After the pre - treatment is completed, the valve is closed, and then the spray head 12 is operated. The spray head 12 discharges high - pressure and a large amount of rinsing liquid, which can quickly and effectively wash away the softened scabs and other foreign matters.

[0075] Refer to Figure 9 - Figure 12 A wiping piece 30 is provided on the outer circle of the spray head 12. The wiping piece 30 is arranged in a frustum shape. The reduced - diameter edge of the wiping piece 30 is embedded in the annular groove 31 opened on the outer circle of the spray head 12, and a medical cotton strip 32 is provided on the flared edge of the wiping piece 30;

[0076] The provided wiping piece 30 cooperates with the medical cotton strip 32. The medical cotton strip 32 can not only assist the rinsing liquid in treating the wound scab, but also wipe the transparent film 8;

[0077] The medical tampon 32 assists in the treatment of wound scabs with the flushing solution. For some scabs with strong adhesion or those adhering to the surface skin tissue, loosen the ejector rod 20, the spray head 12 sprays the flushing solution, and wipe the scab with the medical tampon 32 to wipe and shave it off the wound;

[0078] Wipe the transparent film 8 with the medical tampon 32. Some of the flushing solution is dark brown. When it splashes onto the transparent film 8, it will block the line of sight for observing the wound. Therefore, the medical tampon 32 can be used to wipe the transparent film 8 to ensure a clear line of sight.

[0079] Refer to Figure 5 - Figure 8 A plug hole 33 is opened at the position where the hose 4 is connected to the adsorption cover 5. The reduced-diameter edge of the adsorption cover 5 is provided with a cylindrical connecting portion 34, and the connecting portion 34 is embedded in the plug hole 33;

[0080] By embedding the connecting portion 34 in the plug hole 33, the installation of the adsorption cover 5 is realized. The adsorption cover 5 is set in a detachable manner, and the size of the adsorption cover 5 has multiple specifications, which are selected according to the position of the wound on the patient's body. For example, on the relatively flat skin surface of the chest, some adsorption covers 5 with larger adsorption openings can be installed. At some positions with more skin folds, such as some joint positions with more skin folds, in order to ensure the adsorption effect between the adsorption cover 5 and the skin, some adsorption covers 5 with smaller adsorption openings can be used. The adsorption cover 5 can effectively cover the skin surface and ensure continuous and stable adsorption force.

[0081] Refer to Figure 5 - Figure 8 The edge of the connecting portion 34 is arranged in an arc shape, and the edge of the connecting portion 34 is flush with the inner surface of the hose 4;

[0082] The edge of the connecting portion 34 is flush with the inner surface of the hose 4, so that the softened scab or pus flowing in the hose 4 can flow smoothly, so as to prevent the scab from being stuck at the gap between the connecting portion 34 and the hose 4, and the scab or foreign matter causes the blockage of the hose 4.

[0083] Refer to Figure 5 - Figure 8 An annular groove 35 is opened on the outer circle of the connecting portion 34, and a protrusion 36 is provided on the edge of the connecting portion 34, and the protrusion 36 is arranged along the edge; a sealing ring 37 is provided on the inner side wall of the plug hole 33. When the connecting portion 34 is embedded in the plug hole 33, the sealing ring 37 is embedded in the groove 35, and the protrusion 36 fills the gap between the edge of the connecting portion 34 and the inner hole edge of the plug hole 33;

[0084] Since the hose 4 itself is soft and plastic, when the bending degree of the hose 4 is too large, the deformation of the plug hole 33 is large, which may cause a gap between the plug hole 33 and the connecting part 34. The adsorption effect of the adsorption cover 5 connected to the plug hole 33 at this position is not good. Therefore, the sealing ring 37 is provided to cooperate with the groove 35 to enhance the strength of the plug hole 33 and ensure a stable sealing performance between the adsorption cover 5 and the hose 4;

[0085] At the same time, a protrusion 36 is provided at the edge of the connecting part 34. The protrusion 36 can further fill the gap between the edge of the connecting part 34 and the inner hole edge of the plug hole 33, reduce the possibility of foreign matter filling, and improve the sealing performance between the adsorption cover 5 and the hose 4.

[0086] The specific usage method of the wound irrigator is as follows:

[0087] First, attach the hose 4 to the patient's body. The closed loop formed by the hose 4 surrounds the wound. Moreover, the hose 4 itself is plastic and can flexibly adjust the shape of the closed loop according to the shape of the wound and the specific position of the wound on the patient's body. Then, drive an external negative pressure pump to pump air. At this time, the soft adsorption cover 5 can be adsorbed on the patient's body. At the same time, the soft baffle 7 is squeezed between the adsorption cover 5 and the patient's skin under the adsorption force, and the edge of the baffle 7 also adheres to the patient's skin surface. At this time, the hose 4 cooperates with the baffle 7 to surround the wound. Then, drive an external liquid pump, and the external liquid pump injects the flushing liquid into the flushing head 1. The flushing liquid sprays on the wound, continuously flushing the wound, washing off the scabs, pus or foreign matter at the wound, and at the same time disinfecting the wound. The excess flushing liquid will flow along the skin to the lower position of the closed loop formed by the hose 4. At this time, the inside of the adsorption cover 5 is in a negative pressure state. Since a plurality of notches 6 are provided at the edge of the adsorption cover 5, the flushing liquid will be adsorbed into the adsorption cover 5 along the notches 6 and be drawn away along the hose 4 and the adsorption tube 2. At the same time, the softened scabs, diluted pus or foreign matter will also be drawn away;

[0088] The wound irrigator surrounds the periphery of the wound in a cofferdam manner to restrict the flow of the flushing liquid and avoid pollution caused by the random flow of the flushing liquid. At the same time, the plastic hose 4 can flexibly adjust the shape of the closed loop according to the specific shape and position of the wound, with high flexibility, adapting to the wound conditions of more parts of the patient's body. In addition, the adsorption cover 5 can not only adsorb and squeeze the hose 4 and the baffle 7 on the patient's skin surface, but also draw away the excess flushing liquid, avoiding the overflow of the continuously sprayed flushing liquid from the closed loop formed by the hose 4, reducing the trouble of cleaning the flushing liquid before removing the hose 4 later, facilitating the medical staff to irrigate the patient's wound, reducing the execution actions that the patient needs to cooperate with when flushing the wound, and reducing the pain of the patient.
