In order to be able to understand the technical means of the present invention more clearly and implement it according to the content of the specification, the following will describe the preferred embodiments of the present invention in detail in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 is an exploded view of the dedicated treatment tool according to an embodiment of the present invention;

[0024] Figure 2 is Figure 1 the front view of the dedicated treatment tool in

[0025] Figure 3 is Figure 1 a side view of a dedicated treatment tool in Specific Embodiments

[0026] The following combines the accompanying drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0027] An emergency kit according to an embodiment of the present invention includes a dedicated treatment tool 10, and the dedicated treatment tool 10 includes a liquid storage member 20, a lid 30 and a liquid outlet member 40. Among them, a liquid storage cavity 21 is formed in the liquid storage member 20, and the liquid storage member 20 further includes an inlet 22 and an outlet 23 respectively communicating with the liquid storage cavity 21. The liquid storage member 20 is a deformable member. The lid 30 is used to cover the inlet 22 of the liquid storage member 20, and the liquid outlet member 40 is connected to the outlet 23 of the liquid storage member 20. A liquid outlet gap 41 and a communication pipe 42 are formed in the liquid outlet member 40, and the liquid outlet gap 41 communicates with the outlet 23 of the liquid storage member 20 through the communication pipe 42.

[0028] Specifically, the lid 30 can be threadedly connected to the inlet 22 of the liquid storage member 20 to cover the inlet 22 of the liquid storage member 20. The liquid outlet member 40 can be threadedly connected to the outlet 23 of the liquid storage member 20. When in use, when the liquid storage member 20 is squeezed, the liquid in the liquid storage member 20 can flow into the liquid outlet gap 41 through the communication pipe 42 and then flow out through the liquid outlet gap 41.

[0029] The emergency kit of the embodiment of the present invention can be used for burn treatment. At present, the vast majority of domestic and foreign emergency institutions and the World Health Organization have regarded wound cooling treatment as an important measure for emergency burn treatment. The emergency kit for burn treatment can be configured with medical saline for cooling the wound. In addition, chlorhexidine, as a safe disinfectant, has been widely reported clinically for cleaning and antibacterial of burn wounds. Therefore, the emergency kit for burn treatment can be configured with chlorhexidine. When specifically in use, when rinsing the wound with physiological saline or chlorhexidine disinfectant solution by using the dedicated treatment tool 10, the lid 30 of the dedicated treatment tool 10 is opened, and physiological saline or chlorhexidine disinfectant solution is added to the liquid storage member 20. The lid 30 covers the inlet 22 of the liquid storage member 20, and then the liquid storage member 20 is squeezed. The physiological saline or chlorhexidine disinfectant solution in the liquid storage member 20 can flow into the liquid outlet gap 41 through the communication pipe 42 and then flow out through the liquid outlet gap 41 to rinse the wound.

[0030] The dedicated treatment tool 10 includes a liquid storage member 20, a lid 30, and a liquid outlet member 40. The liquid storage member 20 is a deformable member. A liquid outlet gap 41 and a connecting pipe 42 are formed in the liquid outlet member 40. The liquid outlet gap 41 is connected to the outlet 23 of the liquid storage member 20 through the connecting pipe 42. When the liquid storage member 20 is squeezed, the liquid in the liquid storage member 20 can flow into the liquid outlet gap 41 through the connecting pipe 42 and then flow out through the liquid outlet gap 41. Thus, when using the dedicated treatment tool 10 to rinse the wound surface with physiological saline or chlorhexidine disinfectant solution, the physiological saline or chlorhexidine disinfectant solution can be evenly released onto the wound surface, ensuring that the wound surface is evenly rinsed, and facilitating the saving of physiological saline or chlorhexidine disinfectant solution. Furthermore, the first aid kit including the dedicated treatment tool 10 can effectively use the treatment product under limited conditions at the first aid scene, fully exert the use effect of the treatment product, and thus improve the treatment level, which is beneficial to the recovery of the patient's wound surface.

[0031] According to some embodiments of the present invention, the liquid outlet gap 41 is formed as a rectangle, and there are multiple connecting pipes 42. The end of the connecting pipe 42 connected to the liquid outlet gap 41 is a liquid outlet. The multiple liquid outlets are evenly spaced on the side of the liquid outlet gap 41 connected to the connecting pipe 42. Thus, when the liquid storage member 20 is squeezed, the physiological saline or chlorhexidine disinfectant solution in the liquid storage member 20 can flow out of the liquid outlet member 40 in a sheet shape, which is beneficial for rinsing large-area or irregular wound surfaces. In addition, treating burn wound surfaces with gel dressings is beneficial for the healing of the wound surfaces. Therefore, the first aid kit can be configured with liquid gel. When using the dedicated treatment tool 10 to apply the liquid gel to the wound surface, the liquid gel in the liquid storage member 20 flows out of the liquid outlet member 40 in a uniform sheet shape, which is beneficial for applying the liquid gel to large-area or irregular wounds, avoiding secondary damage to the wound surface caused by coating the liquid gel.

[0032] Preferably, the liquid outlet member 40 includes a liquid outlet portion 43, the liquid outlet gap 41 is formed in the liquid outlet portion 43, and the liquid outlet portion 43 is formed as a plate. The first aid kit can also be configured with block gel. When using the dedicated treatment tool 10 to apply the block gel to the wound surface, the plate-shaped liquid outlet portion 43 can be used to shovel out the block gel and accurately apply it to the wound surface, avoiding the slippage or deformation of the block gel caused by grabbing the block gel by hand at the first aid scene.

[0033] According to some embodiments of the present invention, the liquid storage member 20 is made of silica gel or polyvinyl chloride. It has low cost and can ensure the deformability of the liquid storage member 20.

[0034] According to some embodiments of the present invention, the lid 30 is made of polyvinyl chloride.

[0035] According to some embodiments of the present invention, the first aid kit further includes a medical dressing, which is preferably a non-sticking gauze dressing. The non-sticking gauze dressing is obtained by adsorbing polyethylene glycol on the gauze dressing body after the gauze dressing body is subjected to plasma surface treatment. The non-sticking gauze dressing does not adhere to the wound surface, avoiding secondary injury to the wound surface and causing pain to the patient when replacing the medical dressing, and is beneficial to wound healing. In addition, the preparation method of the medical non-sticking gauze dressing has a simple process, so the price of the medical dressing is low, which is conducive to wide clinical application. Furthermore, the first aid kit including the medical dressing further improves the treatment level and is more conducive to the recovery of the patient's wound surface.

[0036] Preferably, the gauze dressing body is brought into contact with a polyethylene glycol solution so that polyethylene glycol is adsorbed on the gauze dressing body. In order to make polyethylene glycol more simply and fully adsorbed on the gauze dressing body, and then the prepared medical non-sticking gauze dressing has a better effect of not adhering to the wound surface. Specifically, the gauze dressing body can be brought into contact with the surface of the polyethylene glycol solution so that polyethylene glycol is adsorbed on the gauze dressing body, or the gauze dressing body can be immersed in the polyethylene glycol solution so that polyethylene glycol is adsorbed on the gauze dressing body.

[0037] Preferably, the mass concentration of polyethylene glycol in the polyethylene glycol solution is 0.1-20%. The non-sticking gauze dressing prepared by bringing the gauze dressing body into contact with the polyethylene glycol solution of this concentration has a better effect of not adhering to the wound surface.

[0038] Preferably, the molecular weight of polyethylene glycol is 400-20000. The non-sticking gauze dressing prepared by bringing the gauze dressing body into contact with the solution of polyethylene glycol of this molecular weight has a better effect of not adhering to the wound surface. More preferably, the molecular weight of polyethylene glycol is 2000-8000, and the medical dressing prepared by bringing the gauze dressing body into contact with the solution of polyethylene glycol of this molecular weight has the best effect of not adhering to the wound surface.

[0039] The medical dressing in the first aid kit of the present invention will be described below through specific examples.

[0040] Example 1:

[0041] 1) Preparation of the medical dressing of the present invention

[0042] Take the medical degreased gauze as the dressing body, vacuum dry it for 30 min, perform plasma surface treatment on the medical degreased gauze (the process parameters of the plasma surface treatment are: evacuate to 5 pa, fill in oxygen until the gas pressure is 20 pa, adjust the power to 25 w to start discharging, and the discharging time is 3 min), then immerse the medical degreased gauze in the polyethylene glycol solution for 30 min to adsorb polyethylene glycol on the medical degreased gauze, take out the medical degreased gauze, and dry it in the air to obtain the medical non-sticking gauze dressing of the present invention's example.

[0043] Thus, several medical non-sticking gauze dressings prepared by the preparation method of the medical non-sticking gauze dressing of the embodiment of the present invention were obtained by immersing the medical absorbent gauze after plasma surface treatment in different polyethylene glycol solutions, as shown in Table 1 below;

[0044] Table 1 Medical non-sticking gauze dressings prepared by immersing medical absorbent gauze after plasma surface treatment in different polyethylene glycol solutions

[0045]

[0046]

[0047] 2) At the same time, for comparison, a medical dressing control was also prepared

[0048] Control 1: Take the dressing body of medical absorbent gauze, vacuum dry it for 30 min, and then immerse it in polyethylene glycol solution for 30 min to make polyethylene glycol adsorb on the medical absorbent gauze. Among them, the molecular weight of polyethylene glycol is 4000, and the mass concentration of polyethylene glycol in the polyethylene glycol solution is 2%. Then take out the medical absorbent gauze and dry it in the air to obtain Control 1.

[0049] Control 2: Take the dressing body of medical absorbent gauze, vacuum dry it for 30 min, and then perform plasma surface treatment on the medical absorbent gauze (the process parameters of plasma surface treatment are: evacuate to 5 Pa, fill with oxygen until the gas pressure is 20 Pa, adjust the power to 25 W to start discharging, and the discharging time is 3 min) to obtain Control 2.

[0050] Control 3: Control 3 is medical absorbent gauze.

[0051] Example 2:

[0052] Animal test of medical non-sticking gauze dressing

[0053] After the rabbits were fixed and anesthetized, the hair on the back was removed and further treated with depilatory cream. After making a full-thickness wound with a diameter of about 1 cm on the back of the rabbits using surgical scissors, the exudate on the wound was wiped off, and the wound was covered with a 2*2 cm medical non-sticking gauze dressing. Then the medical non-sticking gauze dressing was fixed with medical waterproof tape. After 24 hours, the medical non-sticking gauze dressing covering the wound was removed, and the adhesion of the medical non-sticking gauze dressing to the wound and the wound healing condition were observed. The adhesion of different medical non-sticking gauze dressings prepared in Example 1 to the wound is shown in Tables 2-4 below. The more "+", the better the performance of the medical non-sticking gauze dressing not adhering to the wound;

[0057]

[0058] Table 4 Comparison of the performance of the medical non-sticking gauze dressing of the present invention not adhering to the wound surface with that of the control

[0059]

[0060] As can be seen from Tables 2 - 4, compared with the control, the medical non-sticking gauze dressing prepared by the preparation method of the medical non-sticking dressing in the embodiments of the present invention has better performance of not adhering to the wound surface. Moreover, when the mass concentration of polyethylene glycol is 0.1 - 20% and the molecular weight of polyethylene glycol is 2000 - 8000, the medical non-sticking gauze dressing prepared by the preparation method of the medical non-sticking gauze dressing in the embodiments of the present invention has the best performance of not adhering to the wound surface.

[0063] Example 3:

[0064] Biocompatibility test of medical dressings

[0065] Skin sensitization test

[0066] The test uses guinea pigs to evaluate the potential skin sensitization reaction of the medical non-sticking gauze dressing. The sample 3 prepared in Example 1 is extracted with 0.9% sodium chloride injection solution to obtain the extract of sample 3. The extract of sample 3 is intradermally injected into 10 test guinea pigs, and bandaged to induce sensitization. In addition, 0.9% sodium chloride injection solution is injected into 5 control guinea pigs. During the recovery period, both 10 test guinea pigs and 5 control guinea pigs are subjected to the challenge test with the extract of sample 3. The results show that no skin sensitization reaction is found in the skin of guinea pigs with the extract of sample 3, and the positive rate of sensitization is 0%.

[0067] Skin irritation test

[0068] 0.5 ml of the extract of sample 3 is dropped onto an absorbent gauze piece with a size of 2.5 cm × 2.5 cm, and applied to the back of the animal. After (1 ± 0.1) h, (24 ± 2) h, (48 ± 2) h and (72 ± 2) h respectively, observe whether there are reactions such as erythema and edema on the back skin of the animal. The results show that the primary irritation index to rabbit skin is 0, and the extract of sample 3 has no irritating effect on rabbit skin.

[0069] Cytotoxicity assay

[0070] After vigorous growth of L929 cells was cultured in the extract of sample 3 (37°C, 5% CO2) for 48 hours, the cell morphology and cell lysis were observed. The results showed that the extract of sample 3 had no toxic effect on L929 cells.

[0071] Example 4:

[0072] Observation on the clinical effect of medical non-stick gauze dressing:

[0073] The medical dressing sample 3 prepared in Example 1 was clinically used in 68 cases. The medical dressing was easy to remove and painless, and there was no adhesion to the wound surface. It not only had good moisturizing properties, was breathable, non-toxic, had no side effects, no allergic reactions, and did not cause allergic reactions. In addition, since the medical non-stick gauze dressing did not adhere to the wound surface, damage to the wound granulation surface and new epithelial tissue was avoided when changing the medical non-stick gauze dressing, which was beneficial to faster wound recovery.
