Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a leak-proof Glauber's salt external application bag. Background Technology
[0002] The Glauber's salt poultice for treating pancreatitis is mainly used to reduce exudation around the pancreas, relieve pancreatic swelling and pain, promote the reduction of edema and the recovery of gastrointestinal function. Glauber's salt has a strong osmotic pressure, which can promote the excretion of local tissue fluid, thereby achieving the effects of reducing swelling and relieving pain. It is an adjunctive treatment for pancreatitis.
[0003] Existing Glauber's salt external application bags have leakage problems, which cause considerable inconvenience during use. Glauber's salt itself is easily soluble in water, which means that a small amount of Glauber's salt will dissolve when using the external application bag. If used improperly, such as using too much Glauber's salt or the patient's skin temperature is high, the dissolution process will be accelerated. In addition, the external environment also affects the stability of Glauber's salt, especially in humid environments, where Glauber's salt is more likely to combine with water vapor in the air and dissolve. This not only reduces the effectiveness of the application but may also cause discomfort to the patient. Therefore, we propose a leak-proof Glauber's salt external application bag. Utility Model Content
[0004] One of the technical problems that this application aims to solve is the leakage problem of the Glauber's salt outer dressing bag.
[0005] To address the aforementioned technical problems, embodiments of this application provide a leak-proof Glauber's salt external dressing bag, comprising a bag body and further comprising:
[0006] The cover is disposed on one side of the bag body, and three Velcro strips are provided between the cover and the bag body for fastening and fixing the bag body and the cover;
[0007] An inner packaging unit, which is disposed inside the bag, is used to load Glauber's salt for external application;
[0008] An efficiency unit, which is installed inside the bag, is used to prevent leakage and to cool down the sodium sulfate inside the grid.
[0009] A fixing unit is disposed outside the bag body and is used to secure the bag body and prevent it from falling.
[0010] In some embodiments, the inner packaging unit includes an inner frame disposed within the bag body, a sticker affixed to one side of the inner frame, a grid disposed within the inner frame, an outer frame disposed outside the inner frame, a plurality of first slots opened at the bottom of the outer frame, an outer ring disposed outside the outer frame, a plurality of second slots opened within the outer ring, and a plurality of torn paper pieces disposed on one side of the outer ring.
[0011] In some embodiments, a plurality of the first slots and the paper fragments are inserted together, and the internal unit is configured as a plurality of units, which are arranged in an equidistant array.
[0012] In some embodiments, the efficiency unit includes a waterproof membrane disposed inside the bag to prevent moisture from penetrating to the outside, an absorbent membrane disposed on one side of the waterproof membrane to absorb excess moisture generated after the sodium sulfate melts, a barrier membrane disposed on one side of the absorbent membrane to prevent sodium sulfate from leaking out, and a cooling bag disposed on one side of the barrier membrane to cool the skin surface and slow down the melting of sodium sulfate.
[0013] In some embodiments, both the barrier film and the cooling bag are slotted, and the barrier film and the cooling bag are sequentially fitted over multiple inner packaging units.
[0014] In some embodiments, the fixing unit includes side adhesive straps disposed on both sides of the bag body, the two side adhesive straps being adhered to each other for laterally binding to the upper abdomen of the patient's torso, and an anti-fall device is provided at the top of the bag body to prevent the bag body from falling.
[0015] In some embodiments, the fall arrestor includes a first connecting strap disposed at the top of the bag body, a rotating joint disposed at the top of the first connecting strap, a buckle disposed between the rotating joint and the first connecting strap, and two second connecting straps disposed at the top of the rotating joint, the two second connecting straps being disposed opposite to each other for binding around the patient's shoulders to prevent falling.
[0016] This utility model has at least the following beneficial effects:
[0017] 1. Align the multiple first slots of the outer frame with multiple pieces of torn paper and insert them. The torn paper pieces break through the packaging paper that seals the bottom of the outer frame. At this time, the sodium sulfate in the grid will be dispersed through the multiple first slots and then through the multiple second slots into the multiple inner units distributed in the array. Since the sodium sulfate in the grid will not be completely dispersed, and the grid's separation makes it evenly distributed, the sodium sulfate will not accumulate in one place. Therefore, the speed of sodium sulfate turning into water can be slowed down, and water leakage can be reduced. In addition, since the inner units are detachable and replaceable, the device can be reused, avoiding waste.
[0018] 2. The absorbent membrane comes into direct contact with the skin and is used to absorb any moisture that seeps out of the Glauber's salt, keeping the applied area dry and preventing skin damage from prolonged dampness. The waterproof membrane in the Glauber's salt application bag prevents sweat from seeping into the Glauber's salt and prevents it from turning into water and leaking out. In addition, the barrier membrane is used to prevent Glauber's salt from leaking out, while the cooling bag can be pressed to produce a cooling effect. When the device is used for a period of time, the skin temperature rises, causing the Glauber's salt to turn into water. At this time, the cooling bag can be used to cool down the Glauber's salt in the grid, so as to slow down the rate of water turning into water and reduce water leakage. At the same time, it cools down the skin, making the binding more comfortable.
[0019] 3. Wrap the device horizontally around the upper abdomen of the pancreatitis patient using two side adhesive straps. Then, loop the two second connecting straps over the shoulders and pass them under the armpits for fixation. Adjust the length and secure the rotating joint to the first connecting strap using a buckle. At this point, the device can be firmly fixed to the patient's upper abdomen using the side adhesive straps and anti-fall device to prevent it from falling. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] Please see Figures 1-5 This utility model provides a technical solution:
[0029] A leak-proof Glauber's salt external application bag includes a bag body 1, and further includes: a cover 2, an inner filling unit 4, an efficiency unit 5, and a fixing unit 6. The cover 2 is located on one side of the bag body 1, and three Velcro strips 3 are provided between the cover 2 and the bag body 1 for adhesive fixation. The inner filling unit 4 is located inside the bag body 1 for loading Glauber's salt for permeation and external application. The efficiency unit 5 is located inside the bag body 1 for leak prevention and cooling of the Glauber's salt inside the grid 403. The fixing unit 6 is located outside the bag body 1 for binding the bag body 1 and preventing it from falling.
[0030] The inner unit 4 includes an inner frame 401 disposed within the bag body 1. A sticker 402 is affixed to one side of the inner frame 401. A grid 403 is disposed inside the inner frame 401. An outer frame 404 is disposed outside the inner frame 401. Multiple first slots 405 are opened at the bottom of the outer frame 404. An outer ring 406 is disposed outside the outer frame 404. Multiple second slots 407 are opened inside the outer ring 406. Multiple torn paper pieces 408 are disposed on one side of the outer ring 406. Between the multiple first slots 405 and the torn paper pieces 408 The internal unit 4 is configured as multiple units, and the multiple internal units 4 are arranged in an equidistant array. It should be noted that the sticker 402 is used to prevent sodium sulfate from leaking out from the outside. Before inserting the internal unit 4, the packaging paper of the prior art needs to be pasted on the bottom of the internal unit 4 to prevent sodium sulfate from leaking out. When inserting the internal unit 4, the paper tearing block 408 can tear the packaging paper, so that sodium sulfate can be scattered from the periphery of the internal unit 4. In addition, the outer ring 406 and the waterproof membrane 501 are pasted together.
[0031] In use, the device is first bound to the upper abdomen of the pancreatitis patient by the fixing unit 6. Then, the cover 2 is opened and the cooling bag 504 and the barrier film 503 are taken out. At this time, multiple inner units 4 are installed. Specifically, the multiple first slots 405 of the outer frame 404 are aligned with multiple broken paper pieces 408 and inserted. The broken paper pieces 408 break through the packaging paper that seals the bottom of the outer frame 404. At this time, the sodium sulfate in the grid 403 will be dispersed through the multiple first slots 405 and then through the multiple second slots 407 to the multiple inner units 4 in the array. Since the sodium sulfate in the grid 403 will not be completely dispersed and the grid 403 divides it evenly, the sodium sulfate will not be completely piled up in one place. Therefore, the speed of sodium sulfate turning into water can be slowed down.
[0032] Dispersed sodium sulfate leaks water more slowly than accumulated sodium sulfate because, in its dispersed state, the pores between sodium sulfate particles are more uniform and smaller, reducing the water flow channels and increasing the difficulty for water to pass through, thus slowing down the leakage rate.
[0033] Example 2
[0034] Please see Figure 3 This utility model provides a technical solution:
[0035] Unlike Embodiment 1, the efficiency unit 5 includes a waterproof membrane 501 disposed inside the bag body 1 to prevent moisture from penetrating to the outside. A water-absorbing membrane 502 is disposed on one side of the waterproof membrane 501 to absorb excess water generated after the sodium sulfate melts. A barrier membrane 503 is disposed on one side of the water-absorbing membrane 502 to prevent sodium sulfate from leaking out. A cooling bag 504 is disposed on one side of the barrier membrane 503 to cool the skin surface and slow down the sodium sulfate decomposition. It should be noted that squeezing the cooling bag 504 can mix and cool the internal cooling substances. The cooling bag 504 is prior art and will not be described in detail here.
[0036] Both the barrier film 503 and the cooling bag 504 are slotted. The barrier film 503 and the cooling bag 504 are sequentially fitted over the multiple inner units 4. When the cover 2 is closed, the barrier film 503 and the cooling bag 504 will not fall off and will fit tightly with the multiple inner units 4.
[0037] When in use, the device is strapped to the upper abdomen of the body, with its absorbent membrane 502 in direct contact with the skin. The absorbent membrane 502 is used to absorb the moisture that seeps out of the Glauber's salt, keeping the applied area dry and preventing the skin from being damaged by prolonged moisture. The waterproof membrane 501 in the Glauber's salt application bag can prevent sweat from seeping into the Glauber's salt and prevent the Glauber's salt from turning into water and leaking out. In addition, the barrier membrane 503 is used to prevent the Glauber's salt from leaking out, while the cooling bag 504 can be pressed to produce a cooling effect. When the skin temperature rises after the device has been used for a period of time, causing the Glauber's salt to turn into water, the cooling bag 504 can be used to cool down the Glauber's salt in the grid 403 to slow down the rate of water turning into water, while also cooling the skin, making the binding more comfortable.
[0038] Cooling down sodium sulfate can slow down its leakage rate. This is mainly because cooling reduces the thermal motion of sodium sulfate molecules, reducing its tendency to seep water outward due to thermal expansion and contraction. At the same time, the low temperature also slows down the exchange rate between sodium sulfate and water vapor in the air, thereby reducing water loss.
[0039] Example 3
[0040] Please see Figure 1 This utility model provides a technical solution:
[0041] Unlike Embodiment 1, the fixing unit 6 includes side adhesive tapes 61 on both sides of the bag body 1. The two side adhesive tapes 61 are glued to each other and used to bind laterally to the upper abdomen of the patient's torso. The side adhesive tapes 61 are elastic. The top of the bag body 1 is provided with an anti-falling component 62 to prevent the bag body 1 from falling.
[0042] The fall arrestor 62 includes a first connecting strap 621 at the top of the bag body 1, a rotating joint 622 at the top of the first connecting strap 621, a buckle 623 between the rotating joint 622 and the first connecting strap 621, and two second connecting straps 624 at the top of the rotating joint 622. The two second connecting straps 624 are arranged opposite each other and are used to tie around the patient's shoulders to prevent falling. The length of the two second connecting straps 624 is adjustable to suit people of different heights and body types.
[0043] When in use, first, the device is horizontally bound to the upper abdomen of the pancreatitis patient through two side adhesive straps 61. Then, the two second connecting straps 624 are put on the shoulders and then passed through the armpits for fixation. Then, the length is adjusted, and the rotating joint 622 is fixed to the first connecting strap 621 through the buckle 623. At this time, the device can be firmly fixed to the upper abdomen of the patient through the side adhesive straps 61 and the anti-fall device 62 to prevent it from falling.
