Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a device and equipment for cleaning limb wounds. Background Technology

[0002] In clinical practice, wound irrigation is an indispensable treatment step for patients with large-area trauma to the limbs. It aims to effectively remove necrotic tissue, bacteria, and other contaminants from the wound surface through repeated and thorough rinsing, creating favorable conditions for subsequent wound repair and healing. Currently, the standard procedure for limb irrigation typically involves placing the affected limb in a large stainless steel basin to hold the necessary disinfectant, saline solution, and other liquids. Healthcare workers then hold the container and continuously pour these liquids onto the surface of the affected limb to achieve thorough cleaning.

[0003] However, this traditional method has revealed a series of problems in practice. Most notably, the direct pouring and high-speed spraying of the irrigation fluid often results in significant splashing. This not only contaminates the area around the surgical site but can also splash directly onto the surgeon's clothing, gloves, and even face, increasing the risk of cross-infection, especially when dealing with highly infected wounds. Furthermore, the disorderly splashing of the fluid can interfere with the surgical field of vision, reducing the precision and efficiency of the surgical procedure. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a device and equipment for cleaning limb wounds.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides:

[0007] A device for cleaning limb wounds, comprising:

[0008] A sleeve defining a receiving cavity having an inlet communicating with the outside, and the sleeve having a plurality of liquid inlet channels distributed along the axial direction;

[0010] Multiple spray heads are located within the accommodating cavity, the spray heads are disposed on the inner wall of the sleeve, and the spray heads are connected to the liquid inlet channel;

[0011] A drain pipe is disposed on the outer wall of the sleeve and communicates with the accommodating cavity.

[0012] Furthermore, the sleeve includes a cylindrical body, and a cover plate is provided at the end of the cylindrical body away from the inlet direction. The cover plate is used to close the end away from the inlet, and the liquid inlet pipe is disposed on the cover plate.

[0013] Furthermore, the sleeve also includes a connecting shell, which is disposed at the end of the cylinder away from the cover plate, and the inner diameter of the connecting shell gradually decreases along the direction away from the cover plate.

[0014] Furthermore, the diameter of the inlet is D1, and the diameter of the accommodating cavity is D2, satisfying that D1 < D2.

[0015] Furthermore, multiple wiping elements are evenly spaced on the inner wall of the sleeve.

[0016] Furthermore, the cylinder body and the cover plate are integrally formed and connected. The liquid inlet channel includes a first channel arranged axially on the cylinder body, and the spray head communicates with the first channel. The liquid inlet channel also includes a second channel arranged radially on the cover plate, and the second channel communicates with the first channel. The liquid inlet pipe communicates with the second channel.

[0017] Furthermore, the cylinder and the cover plate are detachably connected separately. The cover plate includes a first channel arranged axially on the cylinder. The spray head communicates with the first channel. The liquid inlet channel also includes a second channel opened on the side of the cover plate facing the inlet direction. The second channel communicates with the first channel and is also communicated with the liquid inlet pipe.

[0018] Furthermore, a connecting pipe is provided at the end of the connecting shell away from the cover plate, and an annular groove is formed on the outer circumferential surface of the connecting pipe.

[0019] Furthermore, a protective sleeve is detachably fitted on the outer circumferential surface of the connecting pipe, and a strap is provided on the outer circumferential surface of the protective sleeve at the position of the annular groove.

[0021] The limb wound cleaning device described in any of the above items;

[0022] A flushing gun, which is connected to the inlet pipe of the limb wound cleaning device.

[0023] This application achieves limb rinsing within the sleeve's accommodating cavity by providing multiple inlet channels on the sleeve and multiple spray heads communicating with the inlet channels on the inner wall of the sleeve. The rinsing fluid from the inlet pipe is delivered to each spray head through the inlet channel, and the rinsing fluid is discharged to the outside through the drain pipe.

[0040] In clinical practice, if a limb suffers a large-area trauma, the wound needs to be repeatedly rinsed to effectively remove necrotic tissue, bacteria, and other contaminants. Currently, the limb is usually placed in a relatively large rinsing basin, and the wound is continuously rinsed by holding a container containing liquids such as disinfectant and saline. The rinsed liquid flows into the rinsing basin. However, because the human limb is curved, liquid may flow out with the limb during the pouring process, or splashing may occur, contaminating the surgical environment.

[0041] To address the aforementioned issues, this application provides an inlet channel 102 within the cylindrical sleeve 100 housing, and installs multiple spray heads 300 connected to the inlet channel 102 on the inner wall of the sleeve 100. The rinsing fluid is delivered to the inlet channel 102 via the spray heads 300 and then to the spray head 300 position. The spray heads 300 are used to rinse the limbs located inside the sleeve 100, and the rinsed liquid is discharged from the drain pipe 400. The entire rinsing process is completed inside the sleeve 100, thus preventing splashing.

[0042] This application provides a limb wound cleaning device, which includes a sleeve 100, an inlet pipe 200, a spray head 300, and an outlet pipe 400.

[0043] In some embodiments, the sleeve 100 defines a receiving cavity 101 having an inlet 1011 communicating with the outside. The sleeve 100 has a plurality of liquid inlet channels 102 distributed axially. A liquid inlet pipe 200 is disposed in the sleeve 100 and communicates with the liquid inlet channels 102. A spray head 300 is located inside the receiving cavity 101 and is disposed on the inner wall of the sleeve 100, communicating with the liquid inlet channels 102. A drain pipe 400 is disposed on the outer wall of the sleeve 100 and communicates with the receiving cavity 101.

[0044] See Figure 1 , Figure 2 as well as Figure 3As shown, the liquid inlet channel 102 has multiple channels evenly distributed about the central axis of the sleeve 100. The liquid inlet channel 102 is located inside the outer shell of the sleeve 100. The liquid inlet end of each liquid inlet channel 102 is collected at the position of the liquid inlet pipe 200, so that the cleaning liquid from the liquid inlet pipe 200 can be delivered to each liquid inlet channel 102, and then the cleaning liquid can be delivered to each spray head 300 to rinse the limb located in the accommodating cavity 101. The rinsed liquid is discharged through the drain pipe 400.

[0045] Specifically, during use, the patient's limb can be placed in the receiving cavity 101 through the inlet 1011. In one embodiment, there are multiple spray heads 300, each of which is connected to the inlet channel 102 at its location, thereby enabling the liquid from the inlet channel 102 to rinse the limb wound located in the receiving cavity 101.

[0046] It is understandable that the spray head 300 can be multiple holes communicating with the liquid inlet channel 102. Through these holes, the flushing fluid from the liquid inlet channel 102 can be sprayed onto the limb located in the receiving cavity 101. The spray head 300 can also be other components, which are not limited here. In order to allow the used flushing fluid to flow out through the drain pipe 400, the drain pipe 400 is generally placed below the sleeve 100 so that the liquid can flow out under the action of gravity.

[0047] It should be noted that the rinsing solution mentioned above can be medical disinfectant, saline solution, or other liquids. The specific solution can be selected according to the actual needs of the surgery, and there are no restrictions here.

[0048] The sleeve 100 includes a cylinder 110, and a cover plate 120 is provided at the end of the cylinder 110 away from the inlet 1011. The cover plate 120 is used to close the end away from the inlet 1011, and the liquid inlet pipe 200 is disposed on the cover plate 120.

[0049] Please continue reading. Figure 1 and Figure 4 As shown, in order to prevent the flushing fluid from splashing out of the accommodating cavity 101, one of the ports of the sleeve 100 needs to be sealed so that the flushing action is completed in the accommodating cavity 101 and to provide a location for the installation of the inlet pipe 200.

[0050] The sleeve 100 also includes a connecting shell 130, which is disposed at the end of the cylinder 110 away from the cover plate 120. The inner diameter of the connecting shell 130 gradually decreases in the direction away from the cover plate 120. Specifically, the diameter of the inlet 1011 is D1, and the diameter of the accommodating cavity 101 is D2, satisfying that D1 < D2.

[0051] See Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in order to prevent the flushing fluid from splashing out from the inlet 1011 as much as possible, the size of the inlet 1011 is set to be smaller than the diameter of the accommodating cavity 101. In order to prevent the flushing fluid from flowing out from the inlet 1011, a connecting shell 130 is provided at the end of the cylinder 110 away from the cover plate 120. The opening of the connecting shell 130 communicating with the outside is the inlet 1011. Since the inner diameter of the connecting shell 130 gradually decreases along the direction away from the cover plate 120, the opening of the connecting shell 130 is made smaller than the inner diameter of the accommodating cavity 101. Since the drain pipe 400 is lower than the bottom of the inlet 1011, the flushing fluid used for flushing can only flow out from the drain pipe 400 and will not flow out from the inlet 1011. Furthermore, the smaller opening of the inlet 1011 can also reduce the risk of the flushing fluid splashing out from the inlet 1011.

[0052] It is understandable that the connecting shell 130 is conical, and the size of the opening of the connecting shell 130, i.e. the inlet 1011, should be larger than the size of a human limb, so that the limb can enter the receiving cavity 101 through the inlet 1011.

[0053] The inner wall of the sleeve 100 is provided with a plurality of wiping elements 500 at even intervals.

[0054] See Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, during rinsing, if the dirt on the wound surface cannot be washed away by the cleaning solution, the wound surface can be brought into contact with the wiping piece 500 and moved back and forth to wipe away the dirt on the wound surface and achieve wound cleaning.

[0055] In this embodiment, the wiping member 500 can be made of soft materials such as sponge. In order not to affect the spray rinsing of the spray head 300, the position of the wiping member 500 should not affect the spray of the spray head 300. The specific position and number are not limited here.

[0056] In one embodiment, the cylinder 110 and the cover plate 120 are integrally formed and connected. The liquid inlet channel 102 includes a first channel 1021 arranged axially on the cylinder 110, and the spray head 300 communicates with the first channel 1021. The liquid inlet channel 102 also includes a second channel 1022 arranged radially on the cover plate 120, and the second channel 1022 communicates with the first channel 1021. The liquid inlet pipe 200 communicates with the second channel 1022.

[0057] See Figure 2 As shown, the cylinder 110 and the cover plate 120 can be integrally formed, for example, by using 3D printing technology or injection molding. Of course, other technologies can also be used, which are not limited here. The first channel 1021 is located inside the shell of the cylinder 110, and the second channel 1022 is located inside the cover plate 120. The second channels 1022 converge at the position of the liquid inlet pipe 200, so that the rinsing liquid from the liquid inlet pipe 200 can be received and transported to the first channel 1021. Then, the limb wound located in the accommodating cavity 101 is rinsed through the spray head 300 connected to the first channel 1021.

[0058] Furthermore, the cylinder 110 can be made of a soft material that can deform to a certain extent, so that the cylinder 110 can be held and deformed to wipe the patient's limbs through the wiping device 500. The cover plate 120 can also be made of a soft material or a hard material. In this embodiment, the cover plate 120 is made of a hard material and the cylinder 110 is made of a soft material. The soft material can be made of silicone or other materials, and the hard material can be made of polyethylene or other materials. The specifics are not limited here.

[0059] In another embodiment, the cylinder 110 and the cover plate 120 are detachably connected separately. The cover plate 120 includes a first channel 1021 axially disposed on the cylinder 110. The spray head 300 communicates with the first channel 1021. The liquid inlet channel 102 also includes a second channel 1022 opened on the side of the cover plate 120 toward the inlet 1011. The second channel 1022 communicates with the first channel 1021 and the liquid inlet pipe 200.

[0060] See Figure 4 , Figure 5 , Figure 6 ,as well as Figure 7 As shown, the cylinder 110 and the cover plate 120 can be detachably connected. For example, the cover plate 120 can be threaded, such as having an internal thread on the edge flange of the cover plate 120 and an external thread on the end of the outer surface of the cylinder 110 facing the cover plate 120. The cylinder 110 and the cover plate 120 are connected by the cooperation of the internal and external threads, thereby realizing the detachable connection between the cylinder 110 and the cover plate 120.

[0061] See Figure 7 and Figure 8 As shown, furthermore, in order to allow the flushing fluid from the inlet pipe 200 to be delivered to the first channel 1021, a second channel 1022 is opened on the side of the cover plate 120 facing the cylinder 110. This second channel 1022 is annular.Figure 8 As shown, each first channel 1021 is connected to an annular second channel 1022. The diameter of the second channel 1022 should be smaller than the wall thickness of the sleeve 100, so that a seal can be achieved when each first channel 1021 is connected to the second channel 1022. More specifically, a sealing ring (not shown) can be provided at the connection between the cover plate 120 and the cylinder 110. The sealing ring is used to seal the connection between the cylinder 110 and the cover plate 120, preventing the flushing fluid from leaking at the connection between the first channel 1021 and the second channel 1022.

[0062] Furthermore, the cylinder 110 can be made of a soft material or a hard material. Since the cylinder 110 and the cover plate 120 are connected separately, when the cylinder 110 is made of a soft material, the connection between the cylinder 110 and the cover plate 120 can be made of a hard material. That is, the cylinder 110 transitions to the cover plate 120 through a hard material part. The cover plate 120 can be made of a hard material. The soft material can be silicone, and the hard material can be polyethylene. The specific material type is not limited here.

[0063] A connecting tube 600 is provided at the end of the connecting shell 130 away from the cover plate 120. An annular groove 610 is provided on the outer peripheral surface of the connecting tube 600. A protective sleeve 700 is detachably fitted on the outer peripheral surface of the connecting tube 600. A strap 710 is provided on the outer peripheral surface of the protective sleeve 700 at the position of the annular groove 610.

[0064] See Figure 3 As shown, to further prevent the flushing fluid from splashing to the outside from the inlet 1011, a connecting pipe 600 is provided on the end face of the connecting shell 130 away from the cover plate 120, and an annular groove 610 is opened on the outer circumferential surface of the connecting pipe 600. Specifically, in use, a protective sleeve 700 can be fitted on the outer circumferential surface of the connecting pipe 600. The port of the protective sleeve 700 facing the cylinder 110 is connected to the inlet 1011, and the port of the protective sleeve 700 away from the cylinder 110 is connected to the outside. In order to prevent the protective sleeve 700 from separating from the connecting pipe 600, after the protective sleeve 700 is fitted on the connecting pipe 600, the protective sleeve 700 is fixed to the connecting pipe 600 at the position of the annular groove 610 by a strap 710. It can be understood that the protective sleeve 700 will be partially recessed into the annular groove 610 under the binding force of the strap 710, so the protective sleeve 700 is not easy to separate from the connecting pipe 600.

[0065] Please continue reading. Figure 3As shown, the patient's limb passes through the protective sleeve 700, connecting tube 600, and inlet 1011 into the receiving cavity 101. Then, the protective sleeve 700 is tied to the limb with a rope at the end of the protective sleeve 700 away from the cylinder 110, thereby completely preventing the irrigation fluid from the cylinder 110 from splashing out from the inlet 1011 and causing contamination of the surgical environment.

[0066] In this embodiment, in order to accurately observe the rinsing situation inside the cylinder 110, the sleeve 100 can be made of transparent material.

[0067] This application embodiment also provides a limb wound cleaning device, which includes the limb wound cleaning apparatus described in any of the above claims and a flushing gun, wherein the flushing gun is connected to the liquid inlet pipe 200 of the limb wound cleaning apparatus.

[0068] Specifically, the flushing gun can deliver the cleaning fluid to the inlet pipe 200, and then deliver the cleaning fluid to the spray head 300 through the inlet channel 102. The spray head 300 is used to clean the limbs located in the accommodating cavity 101. It can be understood that the flushing gun has the ability to deliver liquid, and a flushing gun that can change the liquid pressure can be selected as needed. This is not limited here.
