[0002] In the field of clinical medical care, wound and stoma care has always been an important and challenging link. Wounds, especially deep traumas, surgical incisions, etc., are extremely vulnerable to invasion by external pathogens such as bacteria and viruses due to the damaged skin barrier. And stoma patients, due to the diversion of the intestinal or urinary tract, lack the protection mechanism of normal skin at the stoma site and are even more at high risk of infection. According to authoritative medical statistics, the conventional wound infection rate fluctuates within a certain range, while the incidence of infection after stoma surgery is at a relatively high level. This not only prolongs the patient's hospital stay, increases medical costs, but also brings great physical and mental pain to the patient.

[0003] Traditional wound and stoma care methods mainly rely on means such as regular dressing changes. However, multiple dressing changes expose the wound multiple times, creating opportunities for germs to invade the wound; especially for wounds with exudate, in the case where the exudate cannot be cleaned in time, it is easier to breed bacteria, and then the problem of wound infection occurs.

[0021] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present invention pertains. Words such as "including" or "comprising" and the like mean that the elements or items appearing before the word cover the elements or items listed after the word and their equivalents, without excluding other elements or items. "Inner", "outer", "upper", "lower", "far", "near", "front", "rear", etc. are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0022] The accompanying drawings in the present invention are not strictly drawn to actual scale, and the specific dimensions and quantities of each structure can be determined according to actual needs. The accompanying drawings described in the present invention are only schematic diagrams, such as Figures 1-14 .

[0023] As a first embodiment A wound and stoma infection prevention nursing device provided by the present invention includes a box body 1. The bottom of the box body 1 has a through hole, and a gauze 2 is arranged in the through hole. A dressing for covering the wound is arranged on the outer surface of the gauze 2; The box body 1 has a cavity 3 for placing water-absorbing resin, and water-absorbing resin for absorbing exudate from the wound is placed in the middle of the cavity 3; The wound and stoma infection prevention nursing device further includes a capsule 4 with liquid medicine inside. The capsule 4 is located on the inner wall of the cavity 3, and the capsule 4 has a liquid outlet 5. The liquid outlet 5 is communicated with a perforation 6 provided on the bottom wall of the cavity 3, and the perforation 6 is communicated with an annular groove 7 provided on the bottom wall of the cavity 3.

[0024] The bladder body 4 is made of rubber material, and the liquid outlet 5 on the bladder body 4 is a slit on the side wall of the bladder body 4. When the bladder body 4 is not squeezed, the slit is closed. After the bladder body 4 is squeezed, the slit opens, enabling the liquid medicine to flow out from the slit.

[0025] When this wound and stoma infection prevention nursing device is in use, align the through hole with the wound, and at the same time tie the box body 1 to the patient's body with a bandage. During this period, the dressing on the gauze 2 is used to promote the healing of the patient's wound. When the patient's wound continuously oozes exudate, the exudate can contact the water-absorbing resin through the gauze 2 and be absorbed by the water-absorbing resin. The water-absorbing resin gradually swells, and the swollen water-absorbing resin squeezes the bladder body 4 in the cavity 3, enabling the liquid medicine (such as iodophor or normal saline, etc.) in the bladder body 4 to flow from the liquid outlet 5 into the perforation 6 and the annular groove 7, disinfecting the skin around the wound and inhibiting bacteria from infecting the wound.

[0026] This wound and stoma infection prevention nursing device can not only promote wound healing, but also adsorb exudate and inhibit bacteria from further infecting the wound. Its ability to handle wounds is more comprehensive, and it can effectively prevent the wound from deteriorating further.

[0027] Furthermore, a sliding plate 8 is arranged in the box body 1. The two ends of the sliding plate 8 are slidably connected to the opposite side walls of the cavity 3, and the upper and lower edges of the sliding plate 8 are slidably connected to the upper top wall and the lower bottom wall of the box body 1; The upper top wall of the box body 1 is made of transparent material, and a plurality of color display strips 9 with different colors are arranged on the inner side of the lower bottom wall of the box body 1. The plurality of color display strips 9 are evenly arranged along the sliding direction of the sliding plate 8.

[0028] When the water-absorbing resin absorbs exudate and swells, it will squeeze the sliding plate 8, and the sliding plate 8 moves along the arrangement direction of the plurality of color display strips 9. Medical staff and patients can judge the amount of exudate absorbed by the water-absorbing resin by observing the position where the sliding plate 8 moves on the plurality of color display strips 9. When the moving position of the sliding plate 8 is farther, it indicates that the exudate generated by the wound and stoma is more, and the water-absorbing resin absorbs more exudate. It is recommended to replace it in time or perform further treatment; on the contrary, when the moving position of the sliding plate 8 is closer, it indicates that the exudate generated by the wound and stoma is less, and the water-absorbing resin absorbs less exudate. It is recommended to continue observing.

[0029] Furthermore, the inner side wall of the box body 1 is a cylindrical surface. The two ends of the sliding plate 8 are slidably connected to different positions on the cylindrical surface, and the sliding plate 8 has elasticity.

[0030] After the middle part of the elastic sliding plate 8 is squeezed by the water-absorbing resin, the two ends of the sliding plate 8 contract inward, and the curvature of the sliding plate 8 increases. The middle part of the sliding plate 8 moves along the arrangement direction of the plurality of color display strips 9 and gradually approaches the side wall of the cylindrical surface.

[0031] Furthermore, the cross section of the sliding plate 8 is I-shaped, and the upper and lower edges of the I-shaped sliding plate 8 have horizontal portions parallel to each other, and the two horizontal portions are slidably connected to the upper top wall and the lower wall of the box body 1 respectively.

[0032] The two parallel horizontal portions are used for sliding connection with the upper top wall and the lower wall of the box body 1, so that the vertical surface of the sliding plate 8 maintains a stable vertical state, and can also prevent the water-absorbing resin from passing through the gap between the sliding plate 8 and the upper top wall and the lower wall of the box body 1; in order to make the two ends of the sliding plate 8 better slidingly connected with the cylindrical surface, the horizontal portion on the sliding plate 8 is more preferably distributed in the middle part of the sliding plate 8.

[0033] Furthermore, the top of the box body 1 has a cover body 12, the upper top wall of the box body 1 is the inner top wall of the cover body 12, and the side wall of the cover body 12 has a vent hole 10; The box body 1 has a sound hole 11 on its side wall. The inner wall of the sound hole 11 is provided with a reed along the length direction of the sound hole 11 . The sound hole 11 and the air hole 10 are coaxially arranged.

[0034] As a safety measure, the seepage speed of the exudate is usually difficult to detect, and patients and medical staff are unable to observe the moving distance of the sliding plate 8 in time, which may easily delay the treatment of the wound stoma, so the above structure is designed.

[0035] When exudate (or sudden situations, such as blood vessel rupture, etc.) are generated at a fast speed, the water-absorbent resin absorbs the exudate and expands, during which time it squeezes the sliding plate 8. The sliding plate 8 quickly squeezes the air near the color strip 9, so that the air can be discharged to the outside of the box body 1 through the sound hole 11. During the air discharge process, the air rubs against the reed, and the reed vibrates and makes a sound, which is used to remind the patient or medical staff to deal with the wound stoma in time.

[0036] Furthermore, there are two capsules 4 , which are respectively arranged on two opposite sides of the cavity 3 .

[0037] The two capsules 4 are symmetrically designed, and can quickly fill the annular groove 7 and make the liquid medicine evenly distributed on the skin around the wound along the annular groove 7 .

[0038] The working principle of the first embodiment is as follows: When the wound stoma infection prevention nursing device is used, after the box body 1 is tied to the patient's body through a bandage, when the patient's wound continues to exudate, the exudate can contact the water-absorbing resin through the gauze 2 and be absorbed by the water-absorbing resin, and the water-absorbing resin gradually expands; The expanded water-absorbing resin has two functions: The first function is as follows: The swollen water-absorbing resin squeezes the capsule body 4 in the cavity 3, so that the liquid medicine (such as iodophor or physiological saline, etc.) in the capsule body 4 can flow from the liquid outlet 5 into the perforation 6 and the annular groove 7, and sterilize the skin around the wound to inhibit bacterial infection of the wound.

[0039] The second function is as follows: The swollen water-absorbing resin will squeeze the sliding plate 8, and the sliding plate 8 moves along the arrangement direction of the plurality of color display strips 9. Medical staff and patients can judge the amount of exudate absorbed by the water-absorbing resin by observing the position where the sliding plate 8 moves on the plurality of color display strips 9.

[0040] The third function is as follows: It can cope with emergencies, such as blood vessel rupture, etc. When the speed of exudate production is relatively fast, by quickly squeezing the sliding plate 8, the air rubs against the reed, and the reed vibrates to emit a sound, so as to remind the patient or medical staff to process the wound stoma in time.

[0041] On the basis of the first embodiment, the following settings are made and used as the second embodiment.

[0042] Furthermore, a soft cushion ring 13 is also provided at the bottom of the box body 1. The surface of the soft cushion ring 13 is fixedly connected to the bottom of the box body 1. The annular groove 7 is provided on the surface of the soft cushion ring 13 away from the box body 1. The annular groove 7 divides the soft cushion ring 13 into an outer washer 15 and an inner washer 16. The outer washer 15 and the inner washer 16 are fixedly connected by a connecting member 14, and the connecting member 14 is close to the box body 1.

[0043] A gauze ring 23 is sleeved and clamped on the inner wall of the inner washer 16, and the gauze 2 is fixedly connected to the inner wall of the gauze ring 23.

[0044] The soft cushion ring 13 is used to better fit the arc of the human body and prevent the liquid medicine from flowing out of the outside of the box body 1 and the soft cushion ring 13. The connecting member 14 is preferably an elastic rubber block, and can also be selected as a plastic plate. The connecting member 14 enables the outer washer 15 and the inner washer 16 to have a relatively stable positional relationship. At the same time, the connecting member 14 is close to the box body 1, indicating that the connecting member 14 is far from the patient's skin, so that the liquid medicine can smoothly flow from one side of the connecting member 14 to the other side in the annular groove 7.

[0045] Furthermore, an embedded ring groove 17 is provided on the surface of the inner washer 16 away from the box body 1, and a guide through hole 18 is provided at the bottom of the embedded ring groove 17; A temperature conduction ring 19 is embedded in the embedded ring groove 17, and a temperature conduction block 20 is fixedly provided on the temperature conduction ring 19. The temperature conduction block 20 is arranged in the guide through hole 18; Both the temperature conduction ring 19 and the temperature conduction block 20 are made of metal. An installation groove 21 is provided on the inner surface of the bottom of the box body 1. The end of the installation groove 21 communicates with the conduction through-hole 18. A thermometer 22 is clamped in the installation groove 21, and the temperature sensing end of the thermometer 22 contacts the temperature conduction block 20.

[0046] When the box body 1 covers the skin around the patient's wound, the temperature conduction block 20 contacts the patient's skin, and conducts the temperature on the patient's skin to the temperature sensing end of the thermometer 22 through the temperature conduction block 20. The thermometer 22 is used to indirectly display the body surface temperature of the patient, and can monitor the patient's body temperature in real time.

[0047] Furthermore, the soft cushion ring 13 is made of soft silicone material and its surface is coated with an antibacterial coating.

[0048] The soft silicone material has better skin-friendly properties and can adhere to the skin better; the antibacterial coating can reduce bacterial reproduction and avoid wound infection.

[0049] Furthermore, the surface of the temperature conduction ring 19 is flush with the surface of the soft cushion ring 13.

[0050] The purpose is to make the surface of the temperature conduction ring 19 coplanar with the surface of the soft cushion ring 13, increase the contact area with the skin, effectively reduce the pressure on the skin around the wound stoma, and be beneficial to blood circulation and wound recovery.

[0051] The working principle of the second embodiment is as follows: Fix the box body 1 on the patient's wound. While ensuring the anti-bacillus ability and comfort, when this wound stoma infection prevention and care device processes the wound, it can transfer the body surface temperature to the temperature sensing end of the thermometer 22 through the temperature conduction ring 19 and the temperature conduction block 20 for real-time detection of the patient's body temperature.

[0052] Specific application cases: The patient's wound stoma is relatively deep and close to the artery. At the same time, there is exudate flowing out from the wound stoma. Use this wound stoma infection prevention and care device to process the wound. By covering the box body 1 on the wound stoma (the box body 1 can be fixed with the help of transparent medical tape according to the specific situation of the patient), by observing the position where the sliding plate 8 moves on the multiple color display strips 9, judge the amount of exudate absorbed by the water-absorbing resin. If the moving distance of the sliding plate 8 is large, it is necessary to replace this wound stoma infection prevention and care device in time; if the thermometer 22 shows too high or too low temperature, it is necessary for medical staff to check the patient's condition in time; if the sound emitted by the reed is heard, it is necessary for medical staff to check and process the wound stoma in time.

[0053] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
