It may suppurate and become infected, not heal for a long time, and even endanger life due to complications such as systemic infection, gas gangrene, tetanus, etc. Wound irrigation is a widely used treatment method and plays a very important role in wound management. It can hydrate the wound, remove foreign bodies in the wound, and assist medical staff to better examine the wound; common foreign bodies in wounds after human trauma include blood clots, sand, hair, etc. When cleaning them, it is necessary to continuously flush with hydrogen peroxide, iodophor, and normal saline to thoroughly debride the wound foreign bodies; currently, mainly syringes or ordinary irrigators are used to draw the irrigation solution to irrigate the wound. When in use, it is necessary to repeatedly aspirate the irrigation solution, which is time-consuming and laborious.

[0003] The utility model aims at the above problems and provides a double-valve continuous wound irrigator. Summary of the Utility Model

[0004] In order to overcome the problems raised in the background art, the utility model adopts the following technical solutions:

[0005] A double-valve continuous wound irrigator, which comprises:

[0006] An elastic container having a first end and a second end, wherein the elastic container has a compressed state and an expanded state;

[0007] A first flow component and a second flow component, the first flow component is disposed within the first end; the second flow component is disposed within the second end, wherein the flow directions between the first flow component and the second flow component are opposite;

[0008] A first tube and a second tube, the first tube is connected to the first end, and the second tube is connected to the second end;

[0009] Wherein, when the elastic container is converted from the expanded state to the compressed state, the first flow component is opened, so that the first tube is communicated with the elastic container; when the elastic container is converted from the compressed state to the expanded state, the second flow component is opened, so that the second tube is communicated with the elastic container.

[0010] Further, the first end portion has a first channel and a second channel, the diameter of the first channel being greater than that of the second channel, wherein the first flow component is disposed within the first channel.

[0011] Further, the second end portion and the first end portion have the same internal structure.

[0012] In some embodiments of the present application, the first flow component and the second flow component have the same structure.

[0013] Further, the first flow component includes:

[0014] A guide rod disposed within the first channel, wherein the guide rod can approach and move away from the elastic container along the axial extension direction of the first channel towards the elastic container;

[0015] A gasket disposed at one end of the guide rod close to the elastic container and moving synchronously with the guide rod;

[0016] A spring disposed around the outer wall of the guide rod, wherein the spring urges the guide rod to always approach the elastic container.

[0017] Further, a connecting portion is provided within the first channel, the connecting portion having a through hole, the guide rod passing through the through hole, wherein one end of the spring abuts against the connecting portion, and the other end of the spring abuts against one side of the gasket.

[0022] Advantages of the present utility model:

[0023] By setting an elastic container, a first circulation component, and a second circulation component, during use, the second tube is externally connected to a flushing solution container. By pressing the elastic container, the elastic container is converted from an expanded state to a compressed state. During this process, the first circulation component opens to discharge the air in the elastic container. Then, the elastic container relies on its own elasticity to convert from the compressed state to the expanded state, generating a negative pressure inside the elastic container, and further causing the second circulation component to open. At this time, the flushing solution is sucked into the elastic container. In this way, by repeatedly pressing the elastic container, the flushing solution is continuously discharged from the first tube and always remains in a full state. Compared with the traditional method of using a syringe or an ordinary flushing device to extract the flushing solution, it avoids repeatedly sucking the flushing solution, simplifies the operation process of wound flushing, shortens the wound flushing time, and saves the physical labor of medical staff.

[0033] The technical solutions in the embodiments of the present utility model will be clearly and completely described below through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Without conflict, the features in the following embodiments and the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Figure 1 The main technical content of this embodiment is shown. This specific embodiment provides a double-valve continuous wound irrigator, which includes:

[0035] An elastic container 1, the elastic container 1 has a first end 11 and a second end 12. Among them, the elastic container 1 has a compressed state and an expanded state;

[0036] A first circulation component and a second circulation component. The first circulation component is arranged in the first end 11; the second circulation component is arranged in the second end 12. Among them, the circulation directions between the first circulation component and the second circulation component are opposite;

[0037] A first tube 3 and a second tube 4. The first tube 3 is connected to the first end 11, and the second tube 4 is connected to the second end 12;

[0038] Among them, when the elastic container 1 is converted from the expanded state to the compressed state, the first circulation component is opened, so that the first tube 3 is communicated with the elastic container 1. When the elastic container 1 is converted from the compressed state to the expanded state, the second circulation component is opened, so that the second tube 4 is communicated with the elastic container 1.

[0039] During use, the second tube 4 is externally connected to a flushing solution container. By pressing the elastic container 1, the elastic container 1 is converted from the expanded state to the compressed state. At this time, the air in the elastic container 1 is discharged. Then, the elastic container 1 relies on its own elasticity to be converted from the compressed state to the expanded state, so that a negative pressure is generated in the elastic container 1, and then the second circulation component is opened. At this time, the flushing solution is sucked into the elastic container 1. By repeating this process, the elastic container 1 is converted between the expanded state and the compressed state, so that the flushing solution is continuously discharged from the first tube 3 to continuously flush the patient's wound.

[0040] Refer to Figure 2-4, in this embodiment, the first end portion 11 and the second end portion 12 are mirror images of each other. For example, the first end portion 11 has a first channel 111 and a second channel 112, and the diameter of the first channel 111 is greater than that of the second channel 112. Among them, the first flow component is disposed in the first channel 111. More specifically, the second channel 112 is located between the first channel 111 and the elastic container 1, and the first channel 111, the second channel 112, and the elastic container 1 are in communication with each other; in use, the flushing liquid in the elastic container 1 enters the first channel 111 after passing through the second channel 112 and flows out through the first tube 3.

[0041] More specifically, there is also a connecting portion in the first channel 111. The connecting portion is connected to the inner wall of the first channel 111. Among them, the connecting portion includes: a connecting arm and a connecting plate 1111. The connecting arm is used to connect the connecting plate 1111 and the inner wall of the first channel 111. The connecting plate 1111 has a through hole, and the axis of the through hole coincides with the axis of the first channel 111.

[0042] Reference Figure 3 -7, in this embodiment, the first flow component and the second flow component have the same structure. Among them, the first flow component includes: a guide rod 2, a gasket 21, and a spring 23; the guide rod 2 is disposed in the first channel 111. Among them, the guide rod 2 can move closer to and away from the elastic container 1 along the axial extension direction of the first channel 111; the gasket 21 is disposed at one end of the guide rod 2 close to the elastic container 1 and moves synchronously with the guide rod 2. The spring 23 is disposed around the outer wall of the guide rod 2. Among them, the spring 23 urges the guide rod 2 to always be close to the elastic container 1; specifically, the gasket 21 closes the port of the second channel 112, so that the first channel 111 and the second channel 112 are not in communication with each other. When the elastic container 1 is stressed, the elastic container is converted from the expanded state to the compressed state, so that the pressure in the elastic container 1 increases, and then the gasket 21 is pushed open. At this time, the guide rod 2 moves away from the elastic container 1 in the axial extension direction of the first channel 111 and compresses the spring 23. When the elastic container 1 is converted from the compressed state to the expanded state, a negative pressure is generated in the elastic container 1, the spring 23 expands, and the guide rod 2 moves closer to the elastic container 1 in the axial extension direction of the first channel 111 to close the port of the second channel 112.

[0043] Specifically, the guide rod 2 passes through the through hole of the connecting plate 1111. One end of the spring 23 abuts against the connecting plate 1111 of the connecting portion, and the other end of the spring 23 abuts against one side of the gasket 21, so that the gasket 21 always closes the port of the second channel 112.

[0044] Specifically, the gasket 21 is circular in shape. The diameter of the gasket 21 is smaller than the diameter of the first channel 111 and larger than the diameter of the second channel 112. When the gasket 21 moves away from the elastic container 1 along with the guide rod 2, the flushing liquid in the elastic container 1 flows into the second channel 112. At this time, the gasket 21 with a diameter smaller than that of the second channel 112 will not affect the entry of the flushing liquid into the first tube 3, thus ensuring the normal outflow of the flushing liquid from the elastic container 1.

[0045] As can be understood by those skilled in the art, the second flow component also includes: a guide rod 2, a gasket 21, and a spring 23. When the elastic container 1 is stressed, the elastic container changes from the expanded state to the compressed state. At this time, the gasket 21 of the second flow component always closes the second channel 112 of the second end portion 12 under the action of pressure, preventing the flushing liquid from entering the elastic container 1. The gasket 21 of the first flow component moves away from the second channel 112 of the first end portion 11, allowing the flushing liquid to flow out of the elastic container 1. Conversely, when the elastic container changes from the compressed state to the expanded state, a negative pressure is generated in the elastic container 1. The gasket 21 of the second flow component moves closer to the elastic container 1 under the action of the negative pressure, enabling the flushing liquid to enter the elastic container 1. At this time, the gasket 21 of the first flow component also moves closer to the elastic container 1 under the action of the spring 23, preventing the flushing liquid from flowing out, and thus keeping the elastic container 1 always full. Based on this, during use, one end of the first tube 3 is aligned with the patient's wound, and then the elastic container 1 is intermittently stressed to continuously flush the patient's wound.

[0046] Reference Figure 2 In this embodiment, it further includes: a housing 5. The housing 5 has a hollow portion. The elastic container 1 is disposed inside the housing 5 and partially extends out of the hollow portion. The first end portion 11 and the second end portion 12 extend out of the housing 5. More specifically, the housing 5 has two opposite hollow portions, and the elastic container 1 partially extends out of the two hollow portions. During use, the doctor holds the housing 5 and then applies force to the elastic container 1 through the hollow portion, causing the elastic container 1 to change from the expanded state to the compressed state. And through the first end portion 11 and the second end portion 12, the elastic container 1 will not come out of the housing 5 when in the compressed state.

[0047] In this embodiment, the elastic container 1 is made of one of rubber, silica gel, and latex, and preferably rubber. When made of this material, the elastic container 1 has good elasticity and can quickly return to the expanded state by relying on its own elasticity after being applied with force. More specifically, the elastic container 1 has two connecting segments arranged in a mirror image of each other. Among them, the first end 11 and the second end 12 are respectively partially located in the connecting segments. Preferably, the first end 11 and the second end 12 are made of a hard material, specifically one of polycarbonate, polyurethane, and polyvinyl chloride.

[0048] Reference Figure 1 and Figure 8 , in this embodiment, the first tube 3 has a liquid inlet end and a liquid outlet end opposite to each other. The liquid inlet end is connected to the first end 11. Among them, the liquid outlet end is configured with a liquid discharge head 31 communicating with the first tube 3. When in use, the doctor holds the liquid discharge head 31 to align it with the patient's wound, and then applies force to the elastic container 1 to flush the patient's wound.

[0049] More specifically, the liquid discharge head 31 is detachably connected to the liquid outlet end. Among them, the liquid discharge head 31 has a liquid outlet channel, and the diameter of the liquid outlet channel is smaller than the inner diameter of the first tube 3. In this setting, when the flushing liquid flows out from the liquid discharge head 31 with an inner diameter smaller than that of the first tube 3, the flow rate of the flushing liquid increases. When in use, when the depth of the patient's wound is relatively shallow, the liquid discharge head 31 can be detached from the first tube 3 to flush the patient's wound with a large flow rate. When the patient's wound is deeper or there are foreign objects in the depth, the liquid discharge head 31 is installed at the liquid outlet end of the first tube 3 to increase the pressure of the flushing liquid, so as to facilitate flushing out the foreign objects deep in the patient's wound.

[0050] Preferably, the first tube 3 is a hard tube. When in use, the doctor holds the elastic container 1, and the liquid discharge end of the first tube 3 can be aligned with the patient's wound, so as to facilitate the flushing operation for the patient's wound.

[0051] In this embodiment, the second tube 4 has a joint end. Among them, the second tube 4 is externally connected to a container containing flushing liquid through the joint end. Alternatively, a bottle stopper puncture device is provided at the second end. When in use, the bottle stopper puncture device is inserted into the bottle stopper of the normal saline bag to supply flushing liquid to the elastic container 1.

[0052] The usage method of the present utility model:

[0053] 1. First, externally connect the second tube to the flushing liquid container, and the doctor holds the elastic container so that the liquid discharge end of the first tube is aligned with the patient's wound;

[0054] 2. Then apply a force to the elastic container, and the elastic container is converted from the expanded state to the compressed state. The second flow component opens, and the flushing liquid flows from the elastic container into the first tube and is discharged from the first tube. In this way, the wound site of the patient is flushed.

[0055] 3. When the elastic container is converted from the compressed state to the expanded state, a negative pressure is generated in the elastic container. At this time, the second flow component is opened under the action of the negative pressure, so that the flushing liquid can enter the elastic container to keep the elastic container always in a full state.

[0056] 4. Apply a force to the elastic container intermittently to continuously flush the wound of the patient.

[0057] The description of the above embodiments is only for understanding the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can be made to the present invention, and these improvements will also fall within the protection scope of the claims of the present invention.
