[0029] like Figures 1 to 11As shown, an embodiment of the present invention provides a leakage-proof sodium sulfate external application device, comprising an external application bag 1 and a support frame 16, a zipper 3 is arranged on the outside of the external application bag 1, and Velcro 2 is symmetrically connected to the top of the external application bag 1, and two groups of Velcro 2 are respectively sewn with Velcro fur surface and Velcro felt surface, and the external application bag 1 is disc-shaped as a whole. After opening the zipper 3, the space inside the external application bag 1 can be exposed, so that it is convenient to add sodium sulfate powder into the external application bag 1. After loading the sodium sulfate, the external application bag 1 can be closed by the zipper 3, so that the loading operation of the sodium sulfate powder is simple and convenient. When the patient uses the device for external application, the external application bag 1 is bound and fixed to the patient's body by the Velcro 2. The method of fixing with Velcro 2 is simple and convenient to operate and has high stability. Secondly, it has a wide adjustment range and can adapt to patients of different body shapes. The outer ring part of the bottom of the external compress bag 1 is fixedly connected with a water-absorbing edge 11. The water-absorbing edge 11 can absorb the moisture sucked out of the patient's body during the external compress process and the moisture generated by the heating of the Glauber's salt itself, thereby preventing water from leaking from the external compress area and causing pollution to the surrounding of the external compress position. A contact area 10 is arranged at the middle position of the bottom of the external compress bag 1. The thickness of the fabric in the contact area 10 is less than the thickness of the fabric of the external compress bag 1. The support frame 16 is sleeved on the inner side of the water-absorbing edge 11. The setting of the contact area 10 makes it easier for the Glauber's salt powder particles in the contact area 10 to pass through the contact area 10 to act on the patient's external compress position when the device as a whole is in the external compress state, thereby ensuring the external compress effect.

[0030] The support component is used to prop up the water-absorbing edge 11, and the support component is connected to the support frame 16; the reinforcement component is used to assist the support component in fixing the connection with the external application bag 1, and the reinforcement component is connected to the support component. The support component can be assembled and connected with the external application bag 1. After assembly, the water-absorbing edge 11 can be supported and the shape of the water-absorbing edge 11 can be restricted. On the one hand, a gap between the water-absorbing edge 11 and the patient's skin is avoided, which may cause leakage. On the other hand, the water-absorbing edge 11 can be avoided from folding and affecting the water-absorbing effect of the water-absorbing edge 11. The reinforcement component is used to assist the assembly and connection between the support component and the external application bag 1, so that the operation of setting the support frame 16 into the water-absorbing edge 11 is simple and convenient, and the connection relationship between the entire support component and the external application bag 1 is stable and reliable, which not only ensures the stability of the entire device during use, but also makes the use and operation of the entire device simple and convenient, and will not increase the workload of medical staff.

[0031] In this embodiment, if Figures 1 to 6As shown, the water-absorbing edge 11 is made of a water-absorbing towel, and a closed ring 12 is fixedly connected to the middle part of the outer side of the water-absorbing edge 11, and the closed ring 12 is made of medical rubber. The water-absorbing edge 11 is an annular cloth belt, and the water-absorbing towel can ensure its water absorption effect. The annular structure can be adapted to the overall shape of the external compress bag 1, and the contact area 10 at the bottom of the external compress bag 1 is formed, and then the main area where water is generated during the external compress process is surrounded, so as to ensure the water absorption effect of the water-absorbing edge 11 and prevent leakage. After the water-absorbing edge 11 is shaped under the action of the support assembly and the support frame 16, the closed ring 12 is at the bottom of the device and contacts the patient's skin. The closed ring 12 is provided with evenly distributed annular protrusions, which can increase the surface area of ​​the closed ring 12. After the closed ring 12 is fitted with the patient's skin, friction is generated between the closed ring 12 and the patient's skin, thereby increasing the friction between the device and the patient's skin after fixation, and ensuring the stability of the device during use. Secondly, the material of the closed ring 12 is medical rubber, which can avoid irritation to the patient's skin.

[0032] In this embodiment, if Figures 3 to 10 As shown, the support component includes a limit frame 5 fixedly connected to the outside of the support frame 16 and evenly distributed, the end of the limit frame 5 is fixedly connected to the limit head 6, and a first through hole 13 adapted to the size of the limit frame 5 is opened on the water-absorbing edge 11. The support component is used to shape the water-absorbing edge 11 after the assembly between the support frame 16 and the water-absorbing edge 11 is completed, and the side of the external compress bag 1 is limited at the same time. On the one hand, it is avoided that the water-absorbing edge 11 is soft The material of the water-absorbing edge 11 causes a gap with the patient's skin and causes leakage, and on the other hand, the overall shape of the external compress bag 1 is maintained, and the shape of the agglomerated Glauber's salt powder in the external compress bag 1 is controlled to avoid excessive shape changes after the agglomerate of the Glauber's salt and make it difficult to remove it from the zipper 3. The width of the limit head 6 is smaller than the width of the limit frame 5, and the outside of the limit head 6 is provided with uniformly distributed friction lines 20. The setting of the friction lines 20 can increase the contact area between the medical staff's fingers and the limit head 6 when the medical staff pinches the limit head 6, thereby increasing the friction between the medical staff's fingers to prevent the medical staff from slipping when moving the limit head 6. The width of the limit head 6 is smaller than the width of the limit frame 5, so that the area at the end of the limit head 6 is smaller, which facilitates the assembly and connection between the support frame 16 and the support assembly and the external application bag 1. During the connection process, the limit head 6 passes through the gap between other structures, and a first weakened groove 7 is provided at the connection between the limit frame 5 and the limit head 6. The limit frame 5, the limit head 6 and the support frame 16 are an integrated structure made of plastic. The material cost is low and the weight is light, so that the patient will not have too much burden when wearing the device. Secondly, the plastic material has good deformation ability, and there is no need to apply excessive force when performing the matching assembly operation between the support frame 16 and the supporting component and the external application bag 1, which is easy for medical staff to operate.

[0033] In this embodiment, if Figures 2 to 8As shown, the limiting frame 5 is provided with an arc that is adapted to the side shape of the external application bag 1, and the arc structure of the limiting frame 5 can be adapted to the outer edge shape of the external application bag 1. After the external application bag 1 is filled with mirabilite powder, the inner side wall of the limiting frame 5 can be fully released from the outer fitting of the external application bag 1 to form a limit and shape for the external application bag 1. The thickness value at the first weakening groove 7 is less than the thickness value at the limiting frame 5 and the limiting head 6. The first weakening groove 7 forms a thinning structure between the limiting frame 5 and the limiting head 6, so that the strength at the first weakening groove 7 is weaker, and it is easier to deform at the first weakening groove 7 after being subjected to external force. A storage groove 17 is provided in the support frame 16, and a side of the support frame 16 away from the limit frame 5 is rolled up toward the storage groove 17 and provided with a second rolled edge 18, and the end of the water-absorbing edge 11 is provided with a first rolled edge 14 that is adapted to the shape of the second rolled edge 18, and the limit head 6 and the limit frame 5 can bend and deform at the first weakened groove 7, so that the limit head 6 can be bent to a state parallel to the limit frame 5, and it is easy for the limit head 6 and the limit frame 5 to pass through the first through hole 13 on the water-absorbing edge 11, and after the force on the limit head 6 is released, the first weakened groove 7 can be reset under the action of its own elastic force, so that the limit head 6 is buckled on the top of the external application bag 1, forming an auxiliary fixation between the support assembly and the support frame 16 and the external application bag 1.

[0034] In this embodiment, if Figures 6 to 11 As shown, the outer side of the second rolled edge 18 is fixedly connected with evenly distributed fixing plates 19, the positions of the fixing plates 19 correspond one to one with the positions of the limiting frame 5, and the end of the fixing plate 19 is provided with a plug connector 21, and the first rolled edge 14 is provided with a second through hole 15 adapted to the size of the fixing plate 19, and the fixing plate 19 is bent and tilted toward the end of the second rolled edge 18, and the size of the gap generated between the fixing plate 19 and the second rolled edge 18 is adapted to the thickness of the first rolled edge 14, so as to ensure that the fixing plate 19 has a clamping and limiting effect on the first rolled edge 14 after passing through the second through hole 15, and the setting of the plug connector 21 makes the end area of ​​the fixing plate 19 smaller, which is easy to fix the fixing plate 19 as a whole Passing through the second through-hole 15, it is convenient for the sleeve connection between the support frame 16 and the water-absorbing edge 11. After the support frame 16 is sleeved and assembled on the inner side of the water-absorbing edge 11, the second rolled edge 18 fits against the inner wall of the water-absorbing edge 11. At this time, the fixing sheet 19 can pass through the first rolled edge 14 on the water-absorbing edge 11, thereby lifting the end of the water-absorbing edge 11, so that the first rolled edge 14 on the water-absorbing edge 11 fits against the outer side of the second rolled edge 18, so that the shape of the entire water-absorbing edge 11 is completely adapted to the outer shape of the support frame 16, so that the first rolled edge 14 is fully unfolded and can be in full contact with the water in the area surrounded by the water-absorbing edge 11, thereby ensuring the water absorption effect of the water-absorbing edge 11.

[0035] In this embodiment, if Figures 7 to 11As shown, the reinforcement component includes a clamping piece 8 symmetrically connected to the top of the limit head 6, the end of the clamping piece 8 close to the first weakening groove 7 is in an open structure, and the end of the clamping piece 8 away from the first weakening groove 7 is fixedly connected to the limit head 6, and a second weakening groove 9 is provided at the connection between the clamping piece 8 and the limit head 6. The second weakening groove 9 is bent, and the thickness of the second weakening groove 9 is smaller than the thickness of other areas on the clamping piece 8, so that the strength at the second weakening groove 9 is weaker, the end of the clamping piece 8 is parallel to the limit head 6, and the side of the clamping piece 8 is flush with the side of the limit head 6. The external application bag 1 is fixedly connected with an elastic band 4 corresponding to the position of the limit head 6. The middle part of the elastic band 4 is made of rubber band, and the thickness of the elastic band 4 is adapted to the size of the gap between the clamping piece 8 and the limit head 6. After the limit head 6 is buckled on the top of the external application bag 1, the limit head 6 can drive the clamping piece 8 to pass through the elastic band 4, and after passing through, the elastic band 4 is inserted into the gap between the clamping piece 8 and the limit head 6, thereby strengthening the connection between the reinforcement component and the external application bag 1 and improving the strength of the reinforcement component. The reinforcing effect of the parts is achieved. When the clamping piece 8 is moved, the edge of the second weakened groove 9 can bend and produce corresponding deformation, opening one end of the clamping piece 8 with an open structure, which is convenient for inserting the elastic band 4. Pressing the clamping piece 8 can also make the clamping piece 8 fit to the outside of the limit head 6, reducing the gap between the clamping piece 8 and the limit head 6, making the sum of the thickness values ​​of the clamping piece 8 and the limit head 6 smaller, making it easy for the limit head 6 to drive the clamping piece 8 to pass through the first through-hole 13 and the elastic band 4.

[0036] The working principle of the technical solution provided by the present invention is as follows: When in use, open the zipper 3 on the external application bag 1, pour the Glauber's salt powder into the external application bag 1 through the opening at the zipper 3, close the zipper 3, take out the support frame 16, insert the support frame 16 from the bottom of the external application bag 1, move the limit head 6, so that the first weakening groove 7 between the limit head 6 and the limit frame 5 is bent and deformed until the limit head 6 is parallel to the limit frame 5, and pass the limit head 6 through the first through hole 13 on the water absorption edge 11. After the limit head 6 passes through the first through hole 13, release the limit head 6, and the first weakening groove 7 is reset under the action of its own elastic force, and the limit head 6 is buckled on the top of the external application bag 1.

[0037] Pull the elastic band 4, pull it out from under the limit head 6, and pull the elastic band 4 so that the elastic band 4 passes through the gap between the limit head 6 and the clamping piece 8, and remove the pulling force on the elastic band 4, so that the elastic band 4 returns to its original position and is clamped by the limit head 6 and the clamping piece 8. At this time, the support frame 16 is sleeved on the inner side of the water-absorbing edge 11.

[0038] Pinch the end of the water-absorbing edge 11 and pull it toward the outside of the second rolled edge 18, so that the second through hole 15 on the first rolled edge 14 is sleeved on the outside of the fixing plate 19 on the second rolled edge 18. After the fixing plate 19 passes through the second through hole 15, the support frame 16 props up the water-absorbing edge 11 as a whole, and the closed ring 12 is located at the bottom of the device.

[0039] Place the external application bag 1 as a whole outside the area where the patient needs external application, let the contact area 10 contact the patient's skin, wrap the Velcro 2 around the outside of the patient's body and adhere and fix it for external application. The water generated during the external application is absorbed by the water-absorbing edge 11, and the closed circle 12 prevents moisture from leaking out.

[0040] After the external application is completed, tear off the Velcro 2 to release the fixation of the device, pull the first rolled edge 14, remove the second through-opening 15 from between the second rolled edge 18 and the fixing plate 19, pull the elastic band 4, and pull the elastic band 4 out from between the limit head 6 and the clamping plate 8, move the limit head 6 and withdraw the limit head 6 and the clamping plate 8 from the first rolled edge 14, separate the external application bag 1 and the support frame 16, open the zipper 3, take out the agglomerated Glauber's salt, and complete the use process of the entire leakage-proof Glauber's salt external application device.

[0041] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
