Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a sodium sulfate external application device with adjustable external application area and thickness. Background Art

[0002] Pancreatitis can be divided into two types: acute and chronic according to its clinical manifestations and duration of the disease. Acute pancreatitis (AP) is a disease characterized by acute inflammation of the pancreas and histological destruction of acinar cells. It is one of the common digestive system emergencies in the emergency department. It is characterized by pancreatic inflammation, edema, necrosis and bleeding, and has the characteristics of acute onset.

[0003] The conventional methods of western medicine for treating AP include fasting water, rehydration, nutritional support, maintaining body fluid balance, gastrointestinal decompression, inhibiting pancreatic enzyme secretion, inhibiting gastric acid secretion and anti-infection, etc.; commonly used Chinese medicine therapies such as oral administration of Chinese medicine, external application of Chinese medicine, Chinese medicine enema, acupuncture, acupoint injection, etc. have a definite effect on AP and can significantly improve the patient's abdominal symptoms and gastrointestinal dysfunction. At present, the combination of Chinese and Western medicine has become the main treatment for this disease. The Chinese medicine Glauber's salt has the effects of moisturizing dryness and softening hard masses, purging heat and relieving constipation, clearing fire and reducing swelling. Glauber's salt contains sodium sulfate, which has the effects of dissolving gallstones, anti-inflammatory and antibacterial. Glauber's salt applied externally to the abdomen can act directly on the patient's position through the skin, avoiding the first-pass effect through the liver and enhancing the efficacy; at the same time, Glauber's salt applied externally can not only absorb moisture from the abdomen, but also use osmotic pressure to reduce the absorption of peritoneal exudate, accelerating tissue detumescence; and Glauber's salt applied externally can dilate local blood vessels, improve local microcirculation, promote intestinal peristalsis recovery, eliminate abdominal distension, and enhance anti-inflammatory effects. Therefore, external application of Glauber's salt is one of the treatment measures for acute pancreatitis, which can relieve abdominal distension and pain and accelerate the improvement of the disease.

[0004] The traditional Glauber's salt external application bag is a rectangular cloth bag with one side open, which is mostly made by the patient's family with towels or cotton cloth. The size of the external application bag is different, and the thickness of the Glauber's salt in the bag is different, which affects the treatment effect and is difficult to fix. The improved Glauber's salt external application bag has a bag body and a fixing belt. The bag body contains Glauber's salt, and the bag body is fixed to the patient's abdomen by the fixing belt, and the bag body is of uniform size. However, the improved Glauber's salt external application bag still has the following problems: 1) The thickness of the Glauber's salt in the bag body is not easy to control; 2) The area of ​​Glauber's salt external application cannot be adjusted, and it cannot adapt to patients of different body shapes. For example, when the patient is a child, the patient's abdominal area is small, and the bag body is relatively large relative to the patient. When the patient is an adult with a larger body shape, the patient's abdominal area is large, and the bag body is relatively small relative to the patient, which affects the treatment effect. Therefore, it is necessary to design a Glauber's salt external application device with adjustable external application area and thickness. Summary of the invention

[0005] The present invention aims to provide a device for applying sodium sulfate externally with adjustable application area and thickness, so as to solve the problem that the application area of ​​existing sodium sulfate external application bags and the thickness of sodium sulfate in the bag are difficult to adjust.

[0006] In order to achieve the above-mentioned purpose, the scheme of the present invention is: a device for applying sodium sulfate externally with adjustable application area and thickness, comprising a base cloth, a cover cloth, a connecting belt I, a connecting belt II, a detachable frame, a plurality of resisting blocks, a plurality of transverse elastic lines, a plurality of longitudinal elastic lines and a plurality of clamping strips, wherein a cross channel and a transverse channel are provided inside the resisting blocks, the transverse elastic lines pass through the transverse part of the cross channel, the longitudinal elastic lines pass through the longitudinal part of the cross channel, and the transverse elastic lines and the longitudinal elastic lines connect the plurality of resisting blocks into a pressing plate; one end of the connecting belt I is connected to one side edge of the pressing plate, one end of the connecting belt II is connected to the other side edge of the pressing plate, and the other end of the connecting belt I is detachably connected to the other end of the connecting belt II; the detachable frame comprises two longitudinal blocks and a plurality of insertion rods located between the two longitudinal blocks, the corresponding insertion rods pass through the transverse channels of the resisting blocks located in the same row, and at least one end of the insertion rods is detachably connected to the longitudinal blocks;

[0007] A cross groove is provided on the upper surface of the resist block, and the cross grooves on adjacent resist blocks are connected. A connecting piece is provided on the lower surface of the resist block, and after a part of the resist block is folded, it is connected to the part of the resist block that is not folded through the connecting piece; the base cloth is laid on the upper surface of the pressing plate, and the clamping strip clamps the corresponding part of the base cloth into the corresponding cross groove, and the clamping strip clamping the base cloth into the cross groove can form a rectangle, and a receiving groove for containing Glauber's salt is formed between the clamping strip clamping the base cloth into the cross groove and the base cloth; the cover cloth covers the base cloth to cover the receiving groove, and the clamping strip clamps the corresponding part of the cover cloth into the corresponding cross groove, and the clamping strip clamping the cover cloth into the cross groove can form a rectangle.

[0008] The working principle and beneficial effects of this solution are as follows: in this solution, a number of push blocks are connected to form a pressure plate through transverse elastic lines and longitudinal elastic lines, and some push blocks are folded and connected to the unfolded push blocks through connectors, so as to adjust the area of ​​the pressure plate to accommodate patients of different body shapes. Moreover, in this solution, the receiving groove is formed by a base fabric and a clamping strip for clamping the base fabric, and the position of the clamping strip is optional, and the height specification of the clamping strip is optional. After the clamping strips of different heights clamp the corresponding parts of the base fabric into the corresponding cross grooves, the heights of the clamping strips protruding from the base fabric are different, so that the heights of the receiving grooves are different. In this way, the paving thickness of the Glauber's salt is adjustable, that is, the thickness of the Glauber's salt applied externally is adjustable; at the same time, by selecting clamping strips of different lengths and selecting the position where the clamping strips are clamped into the cross grooves, the area of ​​the receiving groove can be adjusted, that is, the area of ​​the Glauber's salt applied externally is adjustable.

[0009] To sum up, in this solution, the area of ​​the pressing plate is adjustable, and the area and thickness of the Glauber's salt application are adjustable. The appropriate area and thickness of the Glauber's salt application can be selected according to the patient's body shape to ensure the therapeutic effect of the Glauber's salt application and the comfort of the patient.

[0010] Optionally, the connecting piece includes a Velcro hook surface and a Velcro fleece surface, and the Velcro hook surface and the Velcro fleece surface are both arranged along the transverse direction of the pressure plate.

[0011] In this solution, after the resisting block is folded, the Velcro hook surface and Velcro fleece surface on the resisting block are adhered to the Velcro hook surface and Velcro fleece surface on the corresponding resisting block, thereby realizing the connection of the folded resisting blocks.

[0012] Optionally, the longitudinal block is provided with a plug hole for inserting the plug rod.

[0013] In this solution, the two ends of the insertion rod are respectively inserted into the corresponding insertion holes of the longitudinal block to realize the detachable connection between the insertion rod and the longitudinal block. In this way, the insertion rod can be separated from the longitudinal block, and the insertion rod can be pulled out of the transverse channel of the block, so that the detachable frame can be removed, and the restriction of the detachable frame on the pressure plate can be released, so that the pressure plate can restore its deformation ability and fit the patient's abdomen.

[0014] Optionally, a threaded section is provided at one end of the insertion rod, and the insertion hole on a longitudinal block is a threaded hole, and the threaded section is threadably matched with the threaded hole.

[0015] In this solution, the plug rod is threadedly connected to a longitudinal block, which is convenient for disassembly and assembly, and the plug rod will not move relative to the longitudinal block, so that all the plug rods can be pulled out at one time.

[0016] Optionally, the connecting belt I and the connecting belt II both include a main belt and three or more branch belts, and ends of the branch belts away from the main belts are evenly distributed on the edge of the pressing plate.

[0017] In this solution, there are more than three connection points between connecting belt I and connecting belt II and the pressure plate. In this way, even if part of the resistance block is folded, connecting belt I and connecting belt II can stably apply tension to the pressure plate to make the pressure plate fit tightly against the patient's abdomen.

[0018] Optionally, the connecting belt I is fixedly connected with a Velcro fleece surface, and the connecting belt II is fixedly connected with a Velcro hook surface.

[0019] In this solution, the Velcro surface on the connecting belt I is adhered to the Velcro hook surface on the connecting belt II, thereby realizing a detachable connection between the connecting belt I and the connecting belt II. In addition, when the connecting piece includes a Velcro hook surface and a Velcro surface, the Velcro surface on the connecting belt I can be adhered to the Velcro hook surface in the connecting piece, thereby fixing the compression plate on a smaller patient (such as a child).

[0020] Optionally, the base cloth is a waterproof cloth, and the cover cloth is a cotton cloth.

[0021] In this scheme, the cover cloth is in contact with the patient's abdominal skin. When Glauber's salt is applied externally, it forms a high osmotic pressure outside the abdominal cavity to absorb effusion and exudate. The base cloth can prevent the liquid from seeping onto the block, thereby avoiding contamination of the patient's clothes and bed sheets.

[0022] Optionally, the mirabilite external application device further comprises a plurality of cross clips, which clip corresponding parts of the base cloth into corresponding cross grooves.

[0023] In this solution, the cross card clips the corresponding part of the base cloth into the corresponding cross groove, thereby forming a barrier in the receiving groove, which to a certain extent hinders the movement of the Glauber's salt in the receiving groove and prevents the Glauber's salt from accumulating on one side of the receiving groove when the patient lies on his side (the patient should press the pressure plate corresponding to the receiving groove with his hand when lying on his side).

In this embodiment, the clamping strips 9 are rubber strips.

[0035] The block 6 is a block of 40mm*40mm*10mm, combined with Figure 2 As shown, a cross channel 601 and a transverse channel 602 are opened inside the stop block 6, the transverse elastic line 7 passes through the transverse part of the cross channel 601, and the longitudinal elastic line 8 passes through the longitudinal part of the cross channel 601, and the transverse elastic line 7 and the longitudinal elastic line 8 connect several stop blocks 6 into a pressure plate 10; both ends of the transverse elastic line 7 and the longitudinal elastic line 8 are connected with anti-retraction parts (not shown) by knotting, and the anti-retraction parts are used to prevent the transverse elastic line 7 and the longitudinal elastic line 8 from retracting into the cross channel 601.

[0036] One end of the connecting belt I3 is connected to one side edge of the pressing plate 10, one end of the connecting belt II4 is connected to the other side edge of the pressing plate 10, and the other end of the connecting belt I3 is detachably connected to the other end of the connecting belt II4. Specifically, the connecting belt I3 and the connecting belt II4 both include a main belt 341 and more than three branch belts 342, and the ends of the branch belts 342 away from the main belt 341 are evenly distributed on the edge of the pressing plate 10; in this embodiment, the number of branch belts 342 is three, so that one branch belt 342 is connected to the middle of the edge of the pressing plate 10, and the other two branch belts 342 are connected to the two ends of the edge of the pressing plate 10. The connecting belt I3 is sewn with a Velcro fleece surface 11, and the connecting belt II4 is sewn with a Velcro hook surface 12, so that the detachable connection between the connecting belt I3 and the connecting belt II4 is achieved through the Velcro fleece surface 11 and the Velcro hook surface 12.

[0037] Combination Figure 3 and Figure 4As shown, the detachable frame 5 includes two longitudinal blocks 501 and a plurality of plug rods 502 located between the two longitudinal blocks 501. The corresponding plug rods 502 pass through the transverse channels 602 of the abutment blocks 6 located in the same row (there are two transverse channels 602 on the abutment blocks 6). At least one end of the plug rods 502 is detachably connected to the longitudinal blocks 501. In this embodiment, the longitudinal blocks 501 are provided with a plug hole 5011 for the plug rods 502 to be inserted, and the plug hole 5011 on the longitudinal block 501 on the left side is a threaded hole. One end of the plug rod 502 is provided with a threaded section, and the threaded section is threadedly matched with the threaded hole; the bottom surface of the longitudinal block 501 and the lower surface of the abutment blocks 6 are in contact with the work surface at the same time. In this way, the detachable frame 5 is used to restrict the pressing plate 10 to prevent the pressing plate 10 from being deformed.

[0038] Combination Figure 2 As shown, a cross groove 603 is formed on the upper surface of the stop block 6, and the cross grooves 603 on adjacent stop blocks 6 are connected. A connecting piece is provided on the lower surface of the stop block 6, and a part of the stop block 6 is connected to the unfolded part of the stop block 6 through the connecting piece after being folded; in this embodiment, the connecting piece includes a Velcro hook surface 12 and a Velcro fleece surface 11, and the Velcro hook surface 12 and the Velcro fleece surface 11 are bonded to the lower surface of the stop block 6, and the Velcro hook surface 12 and the Velcro fleece surface 11 are both arranged along the lateral direction of the pressure plate 10.

[0039] The base fabric 1 is a waterproof fabric with a thickness of h1 mm; the cover fabric 2 is a cotton fabric with a thickness of h2 mm; the depth of the cross groove 603 is h3 mm. The base fabric 1 is laid on the upper surface of the pressing plate 10, and the clamping strip 9 clamps the corresponding part of the base fabric 1 into the corresponding cross groove 603. The clamping strip 9 clamping the base fabric 1 into the cross groove 603 can form a rectangle, and the clamping strip 9 clamping the base fabric 1 into the cross groove 603 forms a receiving groove 13 for containing mirabilite between the base fabric 1 and the base fabric 1, as shown in FIG. Figure 5 As shown. The cover cloth 2 covers the base cloth 1, covering the receiving groove 13, and the card strip 9 inserts the corresponding part of the cover cloth 2 into the corresponding cross groove 603. The card strip 9 that inserts the cover cloth 2 into the cross groove 603 can form a rectangle. Among them, the card strips 9 include card strips 9 of various thicknesses. For example, the total number of card strips 9 is n, the thickness of n / 3 card strips 9 is (h3-h1+2) mm, the thickness of n / 3 card strips 9 is (h3-h1+4) mm, and the thickness of n / 3 card strips 9 is (h3-h2) mm. In this way, after the base cloth 1 is inserted into the corresponding cross groove 603 by the card strip 9, the height of the card strip 9 protruding from the base cloth 1 is 2 mm or 4 mm, that is, the height of the receiving groove 13 is 2 mm or 4 mm, and the thickness of the laid Glauber's salt can be 2 mm or 4 mm, thereby realizing the adjustable thickness of the Glauber's salt external application.

[0040] In actual use, the device is placed flat on a work surface, and then the area required for the external application of the Glauber's salt on the entire abdomen is determined according to the patient's body shape, thereby determining the area of ​​the receiving groove 13, and then determining the position where the clip 9 is inserted into the cross groove 603; after the insertion position of the clip 9 is confirmed, the thickness of the Glauber's salt external application is confirmed, and the clip 9 of appropriate thickness is selected and cut to an appropriate length; then, the corresponding part of the base fabric 1 is inserted into the corresponding cross groove 603 using the clip 9 with a thickness of (h3–h1+2) mm, and the clip 9 inserted into the cross groove 603 of the base fabric 1 can form a rectangle, and the clip 9 inserted into the cross groove 603 of the base fabric 1 forms a receiving groove 13 for accommodating Glauber's salt between the clip 9 and the base fabric 1, as shown in FIG. Figure 5 As shown, at this time, the height of the receiving groove 13 is 2 mm. Then, the medical staff spreads the Glauber's salt in the receiving groove 13, and ensures that the Glauber's salt fills the receiving groove 13 (during the Glauber's salt spreading process, the medical staff can use a scraper to scrape away the Glauber's salt that emerges from the receiving groove 13, which is simple to operate). In this way, the spreading thickness of the Glauber's salt is the same as the height of the receiving groove 13, that is, the spreading thickness of the Glauber's salt is 2 mm.

[0041] After the laying of the sodium sulfate is completed, the cover cloth 2 is covered on the receiving groove 13, and then the corresponding part of the cover cloth 2 is clamped into the corresponding cross groove 603 using the clamping strip 9 with a thickness of (h3-h2) mm. The clamping strip 9 of the cover cloth 2 clamped into the cross groove 603 can form a rectangle to fix the cover cloth 2 and prevent the sodium sulfate from leaking out. Figure 6 shown.

[0042] Then, the medical staff turns over the pressing plate 10 through the detachable frame 5. After the pressing plate 10 is turned over, the cover cloth 2 faces downward and the connecting piece faces upward. The pressing plate 10 is transferred to the patient's abdomen through the detachable frame 5, and the cover cloth 2 contacts the patient's abdominal skin. Next, the medical staff removes the longitudinal block 501 on the right side, and the right end of the insertion rod 502 becomes a free end; then, the medical staff protects the pressing plate 10 with one hand and pulls out the insertion rod 502 to the left with the other hand; as the insertion rod 502 is pulled out, the support force of the insertion rod 502 on the resistance block 6 disappears, and the resistance block 6 naturally falls under the action of gravity and fits the patient's abdomen; until the insertion rod 502 is completely pulled out, the pressing plate 10 fits the patient's abdomen. Then, the patient lifts his waist (or a family member lifts the patient's waist), and the medical staff wraps the connecting belts Ⅰ3 and Ⅱ4 around the patient's back waist, and adheres the Velcro fur surface 11 on the connecting belt Ⅰ3 to the Velcro hook surface 12 on the connecting belt Ⅱ4 to tighten and fix the pressure plate 10.

[0043] Finally, according to the actual situation, it is decided whether to fold the edge of the block 6 to reduce the area of ​​the pressing plate 10. If the area of ​​the pressing plate 10 needs to be reduced, the medical staff folds the block 6 on the pressing plate 10 located in the height direction of the human body, and the connecting piece on the folded block 6 is adhered to the corresponding connecting piece on the unfolded block 6, thereby fixing the folded block 6. After the area of ​​the pressing plate 10 is reduced, it can prevent the pressing plate 10 from pressing the patient's chest, thereby improving the comfort.

[0044] In summary, in this embodiment, the area and thickness of the sodium sulfate external application can be adjusted, and it can be suitable for patients of different body shapes. In addition, the pressing plate 10 in this embodiment can be deformed after the restriction brought by the detachable frame 5 is released, so as to better fit the shape of the patient's abdomen, and the area of ​​the pressing plate 10 can also be adjusted, so that the patient is comfortable during use. In addition, if the patient is a child, the Velcro fur surface 11 on the connecting belt Ⅰ3 can be adhered to the Velcro hook surface 12 on the block 6 after passing around the child's waist, so as to achieve the tightening and fixing of the pressing plate 10.

[0045] Embodiment 2

[0046] The difference between this embodiment and the first embodiment is that: Figure 7 As shown, the sodium sulfate external application device in this embodiment further includes a plurality of cross clips 14, which clip the corresponding portion of the base fabric 1 into the corresponding cross groove 603, and after the cross clip 14 clips the corresponding portion of the base fabric 1 into the corresponding cross groove 603, the height of the cross clip 14 protruding from the base fabric 1 is less than or equal to the height of the receiving groove 13. In addition, the material of the cross clip 14 is the same as that of the clip strip 9, and the cross clip 14 can be deformed.

[0047] In this embodiment, the cross clip 14 forms a block in the receiving groove 13, which hinders the movement of the mirabilite in the receiving groove 13 to a certain extent, and prevents the mirabilite from accumulating on one side of the receiving groove 13 when the patient lies on his side. In addition, when the patient lies on his side, he should pay attention to pressing the pressing plate 10 corresponding to the receiving groove 13 with his hand to avoid a gap between the pressing plate 10 and the patient's abdomen, and further ensure that the mirabilite in the receiving groove 13 will not accumulate on one side.
