Description

Technical Field

[0001] The utility model relates to the technical field of drainage nursing, in particular to a burn effusion drainage nursing device. Background Art

[0002] Burn effusion refers to the abnormal accumulation of fluid in the wound or surrounding tissues after burns. This kind of effusion can occur at all stages of burns, but is common in the initial stage of burns or during the treatment process, especially when the burns are relatively severe.

[0003] After burns, due to tissue damage and inflammatory reactions, a large amount of exudate may be produced in the wound area. If these fluids cannot be effectively removed, they may become an environment for bacterial growth and delay the healing process. Therefore, it is necessary to drain these burn effusions from the affected area. Currently, the common method is to extract them by syringe puncture.

[0004] A patent with the current publication number CN218420535U discloses a fluid extraction device, including a syringe, a connector, a connecting hose and a puncture needle. A tube head is fixed on the side of the syringe, and a connector is sleeved outside the tube head. A connecting rod is arranged inside the syringe. Through the fixed connection between the connector and the connecting outer ring, the connection between the connector and the syringe is more firm and stable, avoiding the loosening of the connection between the connector and the tube head due to the shaking of the syringe when extracting fluid, ensuring the stability of the fluid extraction device during use. Through the anti-slip design of the anti-slip rubber pad, it is more convenient and labor-saving to hold the syringe during use, and at the same time, the stability during holding is ensured. The design of two switch clips can close the connecting hose from the connector, avoiding the outflow of the fluid inside the connecting hose after the switch clip at the bottom of the puncture needle is closed, and preventing external debris from entering the inside of the connector, ensuring the hygiene of the fluid extraction by the device.

[0005] However, in the actual use process of the above extraction device, the following problems still exist:

[0006] After the syringe draws the burn effusion from the affected area into the syringe barrel, since the syringe is a metal pointed object and there is still blood, body fluid or other potential infectious substances left on the surface of the syringe due to puncture, it is necessary to protect the needle. Currently, the method is to put the original needle cap that was originally sleeved on the needle tip back on. However, this method of putting it back not only takes a certain amount of time to align, but may also stab the medical staff, posing a certain safety hazard. Utility Model Content

[0007] Aiming at the deficiencies of the prior art, the utility model provides a burn effusion drainage nursing device to solve the problem that it is inconvenient to protect the needle after using the needle to extract the burn effusion from the patient.

[0008] To achieve the above object, the utility model provides the following technical solution: A burn effusion drainage nursing device, which includes a syringe, two pressing plates installed at the upper end of the syringe, a piston installed inside the syringe, and a needle head installed at the lower end of the syringe. The outer wall of the syringe near the needle head is fixedly connected with two symmetrically arranged supporting semi-rings. Adjacent positions at both ends of the two supporting semi-rings are connected with rotating components. The other ends of the two rotating components are respectively connected with a first cover and a second cover. The other ends of the first cover and the second cover match each other, and the needle head is located inside the first cover and the second cover.

[0009] Further, both rotating components include a rotating rod and a rotating block. The two ends of the two rotating rods are respectively fixedly connected with the inner walls of the adjacent ends of the two supporting semi-rings. The two rotating blocks are respectively sleeved and rotatably connected to the outside of the two rotating rods. The lower ends of the two rotating blocks are respectively fixedly connected with the upper surfaces of the first cover and the second cover.

[0010] Further, a sealing ring is fixedly connected to one side of the first cover close to the second cover. A sealing cavity is formed on one side of the second cover close to the first cover. The outer wall of the sealing ring is slidably connected with the inner wall of the sealing cavity.

[0011] Further, pulling blocks are fixedly connected to the outer walls of the first cover and the second cover on the side away from the supporting semi-rings.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] For this burn effusion drainage nursing device, by arranging two supporting semi-rings at the end of the syringe close to the needle head, and arranging rotating components between the two supporting semi-rings, and connecting the first cover and the second cover through the two rotating components respectively. After the medical staff use the syringe composed of the syringe, the piston and the needle head to drain and extract the effusion at the burn of the patient, the needle head can be wrapped inside the first cover and the second cover, thereby avoiding the exposure of the needle head to the outside, and further avoiding the adhesion of the blood, body fluid or other potential infectious substances remaining on the surface of the needle head to the medical staff, causing injury and infection to the medical staff.

[0020] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 - 5 , a burn effusion drainage nursing device, including a syringe barrel 1, two pressing plates 2 installed at the upper end of the syringe barrel 1, a piston 3 installed inside the syringe barrel 1, and a needle 9 installed at the lower end of the syringe barrel 1. An outer wall of the syringe barrel 1 near one end of the needle 9 is fixedly connected with two symmetrically arranged supporting semi-rings 4. Adjacent parts at both ends of the two supporting semi-rings 4 are respectively connected with rotating components, and the other ends of the two rotating components are respectively connected with a first cover 6 and a second cover 7. The other ends of the first cover 6 and the second cover 7 are matched with each other, and the needle 9 is located inside the first cover 6 and the second cover 7.

[0022] A burn effusion drainage nursing device in this utility model is similar in structure to an existing burn effusion drainage nursing device, such as an effusion extraction device disclosed in a patent with the publication number CN218420535U. As Figures 1 to 5 shown, before the burn effusion drainage nursing device in this utility model is used, the needle 9 is located inside the first cover 6 and the second cover 7 for protection, so as to avoid the needle 9 being contaminated before use. When it is necessary to use a syringe tube composed of the syringe barrel 1, the piston 3, the needle 9, etc. to drain and extract the effusion at the burn of a patient, only need to manually rotate the first cover 6 and the second cover 7 around the two rotating components as the axis, so that the first cover 6 and the second cover 7 can be flipped to both sides of the syringe barrel 1. At this time, the effusion of the burn patient can be drained and extracted through the needle 9. After the drainage and extraction, the first cover 6 and the second cover 7 can be flipped downward again through the rotating components to wrap the needle 9 inside, so as to avoid the needle 9 being exposed outside, and further avoid the blood, body fluid or other potential infectious substances remaining on the surface of the needle 9 from adhering to the medical staff and causing the medical staff to be injured and infected.

[0023] It should be specifically noted here that: a water-absorbing sponge or the like can be arranged in the cavity on the side of the first cover 6 and the second cover 7 close to the needle 9 to adsorb the blood or the like adhered to the surface of the needle 9, so as to further prevent the blood or the like from flowing out of the outside of the channel.

[0024] As Figure 5 shown, both rotating components include a rotating rod 11 and a rotating block 5. The two ends of the two rotating rods 11 are respectively fixedly connected to the inner walls of the adjacent ends of the two supporting half-rings 4. The two rotating blocks 5 are respectively sleeved and rotatably connected to the outside of the two rotating rods 11. The lower ends of the two rotating blocks 5 are respectively fixedly connected to the upper surfaces of the first cover 6 and the second cover 7.

[0025] More specifically, when it is necessary to rotate the first cover 6 and the second cover 7, only need to hold the first cover 6 and the second cover 7 and rotate them towards the direction of the syringe 1. At this time, the first cover 6 and the second cover 7 can rotate around the rotating rod 11 with the rotating block 5 as the axis, so as to achieve the purpose of flipping up the first cover 6 and the second cover 7.

[0026] As Figures 3 - 5 shown, a sealing ring 10 is fixedly connected to the side of the first cover 6 close to the second cover 7. A sealing cavity 701 is formed on the side of the second cover 7 close to the first cover 6. The outer wall of the sealing ring 10 is slidably connected to the inner wall of the sealing cavity 701. By providing the sealing ring 10 and the sealing cavity 701, first, the friction between the first cover 6 and the second cover 7 can be increased to enhance the stability between the two; second, the sealing effect can be enhanced through the sealing ring 10 and the sealing cavity 701, so as to further increase the sealing performance between the first cover 6 and the second cover 7 and prevent the blood or the like from flowing out to the outside.

[0027] As Figures 1 - 5 shown, pulling blocks 8 are fixedly connected to the outer walls of the sides of the first cover 6 close to the second cover 7 and away from the supporting half-ring 4. By providing the pulling blocks 8, it is more convenient to operate when opening and closing the first cover 6 and the second cover 7.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
