Through cooperative arrangement of the external application box, the restraint strap, the heating mechanism and the water injection cavity, in the using process, a nurse can inject hot water at the temperature of about 45 DEG C into the water injection cavity of the external application box through the injection pipe; then, the external application box is placed at the body surface position corresponding to the painful part of the patient, and is wound around the waist and abdomen or other proper parts of the patient through the restraint strap, so that the external application box is stably fixed. When the water temperature in the water injection cavity is reduced to the preset threshold value, a user can start the heating block to work by operating the temperature controller, so that the heating block generates heat after being electrified and conducts the heat to the water body in the water injection cavity to maintain or raise the water temperature, and the hot compress time is prolonged.

Description

Technical Field

[0001] This invention relates to the field of medical care technology, and in particular to a modified Glauber's salt hot compress bag. Background Technology

[0002] Severe acute pancreatitis is a medical emergency with a rapid onset and critical condition, often triggered by factors such as gallstones, hyperlipidemia, or alcohol, leading to a severe inflammatory response in the pancreas and surrounding tissues. This disease not only causes severe abdominal pain, nausea, and vomiting, but can also rapidly progress to multiple organ dysfunction syndrome, such as respiratory failure, renal failure, and circulatory failure, endangering life. Pathologically, it manifests as pancreatic edema, hemorrhage, necrosis, and secondary infection. Treatment emphasizes early fluid resuscitation, gastrointestinal decompression through fasting, analgesia and anti-inflammatory measures, and organ function support. Some cases require surgical or minimally invasive intervention to remove necrotic tissue. Due to its rapid progression and numerous complications, early identification and comprehensive treatment are crucial for improving prognosis. In the nursing care of some pancreatitis patients, topical application of Glauber's salt is often necessary.

[0003] Traditional external application methods suffer from unstable fixation, difficulty in maintaining heat temperature, local skin susceptibility to pressure leading to poor blood circulation, and inconvenience in cleaning. Furthermore, most heat application devices lack temperature control and portable design, making it difficult to meet patients' comprehensive needs for heat application duration, temperature stability, and comfort. Therefore, those skilled in the art provide an improved Glauber's salt heat application bag to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved Glauber's salt hot compress bag.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An improved Glauber's salt hot compress bag includes an outer box, with connecting blocks installed on both sides of the outer surface of the outer box, a restraining strap installed in the middle of the surface of the connecting blocks, and a water injection cavity opened inside the outer box, with heating mechanisms installed on both sides of the inner wall of the water injection cavity. The heating mechanism includes a heating block and a protective box. The protective boxes are installed on both sides of the water injection chamber, and the heating block is installed inside the protective box. Square blocks are installed on both sides of the top surface of the outer dressing box. A shoulder strap is installed in the middle of the surface of the square block. A positioning pin is provided on one side of the surface of the shoulder strap. Positioning holes are equally spaced on the surface of the shoulder strap, and the positioning holes are adapted to the positioning pin. A hollow bag is provided on one side of the surface of the outer dressing box. A compression component is installed on the other side of the hollow bag.

[0006] As a further embodiment of the present invention, the extrusion assembly includes a honeycomb pad, a female Velcro strip, and a female Velcro strip. The female Velcro strip is installed on the front of the hollow bag, and the female Velcro strip is attached to both sides of the front of the female Velcro strip. The honeycomb pad is installed on the front of the female Velcro strip, and a honeycomb-shaped pad is embedded inside the honeycomb pad.

[0007] As a further embodiment of the present invention, an injection hole is provided in the middle of the top surface of the outer dressing box, and an injection tube is inserted into the injection hole.

[0008] As a further embodiment of the present invention, a top cover is threaded onto the top of the injection tube, and an anti-slip film is affixed to the outer surface of the top cover.

[0009] As a further embodiment of the present invention, an adhesive strip is installed on the other side of the inner wall of the outer dressing box, and a splitting plate is adhesively connected to the front of the adhesive strip.

[0010] As a further embodiment of the present invention, one side of the surface of the split plate is attached to one side of the surface of the baffle, and a temperature controller is installed in the middle of the surface of the baffle.

[0011] As a further embodiment of the present invention, the end of the restraint strap is fitted with a buckle, and the outer surface of the restraint strap is covered with a waterproof membrane.

[0012] As a further embodiment of the present invention, an observation window is provided on one side of the outer dressing box, and a transparent scale plate is embedded on the surface of the observation window.

[0013] The beneficial effects of this invention are as follows: 1. Through the coordinated design of the external dressing box, restraint straps, heating mechanism, and water injection chamber, during use, nursing staff can inject hot water at approximately 45℃ into the water injection chamber of the external dressing box via the injection tube. The external dressing box is then placed on the patient's painful area, and the restraint straps are used to secure it around the patient's waist, abdomen, or other suitable locations. When the water temperature in the injection chamber drops to a preset threshold, the user can activate the heating block by operating the temperature controller. The heating block generates heat, which is conducted to the water in the injection chamber to maintain or increase the water temperature, thereby prolonging the hot compress time and ensuring the continuity and effectiveness of the hot compress process. This improves the local physiotherapy effect and comfort for patients with severe acute pancreatitis.

[0014] 2. By designing a synergistic structure between the compression component and the cavity bag, nursing staff can place Glauber's salt inside the cavity bag during use to apply it topically to the affected area using its pharmacological effects. The honeycomb pad on the outside of the cavity bag has a honeycomb-like internal structure, which allows for multi-point contact and moderate compression with the patient's skin during heat application. This effectively disperses pressure, preventing blood flow obstruction, reduced heat dissipation, and abnormal heat accumulation caused by continuous local pressure. This improves comfort and safety during heat application, ensures therapeutic efficacy, and reduces the risk of skin damage.

[0015] 3. By setting up a linked structure for the external dressing box, the compression assembly, and the disassembly plate, after the patient has finished using the device, nursing staff can quickly detach the honeycomb pad from the front of the cavity bag using the adhesive of the female Velcro strap and the female Velcro strip. Furthermore, the compression assembly can be modularly disassembled by removing the disassembly plate connected to the adhesive strip. This detachable structure design facilitates the individual separation, cleaning, and disinfection of the honeycomb pad and other related components, effectively improving the convenience of hygiene maintenance and the reliability of reusability of the device, and meeting the cleaning and infection control requirements of repeated use of medical devices in clinical nursing.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0019] Reference Figures 1-4 An improved Glauber's salt hot compress bag includes an outer box 1. Connecting blocks 2 are installed on both sides of the outer surface of the outer box 1. A restraining strap 3 is installed in the middle of the surface of the connecting block 2. Square blocks are installed on both sides of the top surface of the outer box 1. Shoulder straps 8 are installed in the middle of the surface of the square blocks. A positioning pin 9 is provided on one side of the surface of the shoulder strap 8. Positioning holes are equidistantly opened on the surface of the shoulder strap 8, and the positioning holes are adapted to the positioning pin 9. Buckles 4 are installed at the ends of the restraining straps 3. A waterproof membrane is attached to the outer surface of the restraining straps 3.

[0020] With the configuration of the external dressing box 1, restraint strap 3, shoulder strap 8, positioning pin 9, and buckle 4, when this device is in use, if the caregiver needs to perform external dressing care on the patient, the caregiver can place the external dressing box 1 on the patient's painful area, wrap the restraint strap 3 around the patient's waist, then wrap the shoulder strap 8 around the patient's shoulder, and use the positioning pin 9 to insert into the positioning hole to fix the external dressing box 1, thereby facilitating the caregiver to fix the external dressing box 1.

[0021] In this invention, the outer dressing box 1 has a water injection cavity inside, and heating mechanisms are installed on both sides of the inner wall of the water injection cavity. The heating mechanism includes a heating block 16 and a protective box 17. The protective box 17 is installed on both sides of the inner wall of the water injection cavity. The heating block 16 is installed inside the protective box 17. One side of the surface of the split plate 10 is pasted to one side of the surface of the baffle 6. A temperature controller 7 is installed in the middle of the surface of the baffle 6.

[0022] With the heating mechanism and temperature controller 7 in place, when nursing staff are caring for patients with pancreatitis, they can place hot water into the water injection chamber through the injection tube 5. If the external application time is too long, the medical staff can turn on the temperature controller 7 to turn on the power to the heating block 16, so that the heating block 16 emits heat energy to heat the water source inside the water injection chamber, thereby improving the effectiveness of the hot compress for the patient.

[0023] In particular, a cavity bag 12 is provided on one side of the surface of the outer packaging box 1, and a compression assembly is installed on the other side of the cavity bag 12. The compression assembly includes a honeycomb soft pad 15, a female Velcro strip 14 and a female Velcro strip 13. The female Velcro strip 14 is attached to the front of the cavity bag 12, and the female Velcro strip 14 is attached to both sides of the front of the female Velcro strip 13. The honeycomb soft pad 15 is installed on the front of the female Velcro strip 14, and the honeycomb soft pad 15 is embedded in the interior of the honeycomb soft pad 15.

[0024] With the compression component, when using this device, caregivers can place Glauber's salt inside the hollow bag 12, so that the Glauber's salt inside the hollow bag 12 can be applied externally to the patient's wound. Then, the honeycomb soft pad 15 has a honeycomb structure inside, which can fit and compress the patient's skin, thereby avoiding the accumulation of heat due to local pressure causing obstruction of skin blood flow and reduced heat dissipation.

[0025] In particular, an injection hole is provided in the middle of the top surface of the external dressing box 1, an injection tube 5 is inserted into the injection hole, a top cover is threaded on the top of the injection tube 5, an anti-slip film is attached to the outer surface of the top cover, and an observation window is provided on one side of the external dressing box 1, with a transparent scale plate embedded on the surface of the observation window. With the injection pipe 5 and the top cover, when nursing staff inject hot water into the water injection chamber, they can unscrew the top cover to open the top of the injection pipe 5, thus facilitating the injection of water into the water injection chamber.

[0026] In particular, an adhesive strip 11 is installed on the other side of the inner wall of the outer dressing box 1, and a split plate 10 is adhesively connected to the front of the adhesive strip 11. With the setting of adhesive strip 11 and split plate 10, when the patient is not using the external dressing box 1, the medical staff can remove the honeycomb soft pad 15 and the mother Velcro strip 14 from the surface of the daughter Velcro strip 13. Then, the nursing staff can use adhesive strip 11 to remove the split plate 10, which facilitates the nursing staff to disinfect and clean the honeycomb soft pad 15 one by one.

[0027] It should be noted that the temperature controller 7 is an existing structure, and its model number is XH-W3001; The waterproof membrane attached to the outer surface of restraint strap 3 is made of TPU film, which has good flexibility and waterproof performance, effectively blocking external moisture penetration while maintaining the breathability and wearing comfort of restraint strap 3. The honeycomb pad 15 is a honeycomb structure soft pad made of food-grade silicone material. It has good softness and resilience. Its honeycomb pore design can evenly distribute local pressure and effectively prevent skin blood flow obstruction or heat accumulation caused by pressure during hot compress. The external dressing box 1 is a hollow box structure made of medical-grade ABS injection molding; The model of heating block 16 is: JRD-12V / 220V silicone heating film; The protective box 17 is made of high-temperature flame-retardant ABS engineering plastic.

[0028] Working principle: When using this device, medical staff can place the external dressing box 1 on the patient's painful area, wrap the patient's waist with the restraint strap 3, and then wrap the shoulder strap 8 around the patient's shoulders. The positioning pin 9 is then inserted into the positioning hole to secure the external dressing box 1. Hot water can then be placed into the water injection chamber through the injection tube 5. If the external dressing time is too long, medical staff can turn on the temperature controller 7 to connect the heating block 16 to the power supply, allowing the heating block 16 to emit heat to heat the water source inside the water injection chamber. Simultaneously, the Glauber's salt is packaged in the hollow bag 12, and then the honeycomb pad 15 is attached to the patient's injured skin. Heat is then transferred to the inside of the hollow bag 12 and applied to the patient's skin along the Velcro 13 and the honeycomb pad 15. Finally, when the patient is not using the external dressing box 1, the medical staff can remove the honeycomb pad 15 and the mother Velcro strip 14 from the surface of the mother Velcro 13. Then, the nursing staff can use the adhesive strip 11 to remove the disassembly plate 10, which facilitates the nursing staff to disinfect and clean the honeycomb pad 15 one by one.

[0029] Example 1: Application of hot compress nursing care during the postoperative recovery period of patients with acute pancreatitis Patient's basic information: Male, 45 years old, 3 days post-laparoscopic pancreatic necrosis removal surgery for acute pancreatitis. Chief complaint: persistent upper abdominal distension and pain, VAS pain score: 6. Abdominal examination revealed significant tenderness in the upper and middle abdomen, without rebound tenderness or muscle guarding. Clinical nursing needs: relief of abdominal distension and pain, promotion of gastrointestinal function recovery, and prevention of intestinal adhesions.

[0030] Device configuration and parameter settings: A modified Glauber's salt hot compress bag is selected (the outer box 1 is made of medical-grade ABS material, with dimensions of 25cm×18cm×5cm), the restraint strap 3 is made of TPU waterproof membrane material, and the length adjustment range is 80-150cm; the heating mechanism uses JRD-12V silicone heating film (heating block 16), and the protective box 17 is made of high-temperature flame-retardant ABS material; the temperature controller 7 is model XH-W3001, with a preset temperature threshold of 42℃ and a heating start-up temperature difference of 5℃; the honeycomb soft pad 15 is made of food-grade silicone honeycomb structure with a thickness of 2cm; the hollow bag 12 contains 500g of Glauber's salt (particle size 2-3mm).
