Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an injection site care device for oncology nursing. Background Art

[0002] Tumor injection is one of the methods for treating tumors. Commonly used tumor injections include chemotherapy drug injections, targeted therapy drug injections, and immunotherapy drug injections.

[0003] Tumors are neoplasms formed by the proliferation and abnormal differentiation of body cells under the action of various initiating and promoting factors. Patients often need to undergo multiple injections during the injection treatment process, which will cause more trauma at the injection site. Generally, gauze is used for bandaging and is replaced regularly.

[0004] Since patients need multiple injection treatments and gauze has a certain service life, the gauze on the patient's wound needs to be frequently replaced. However, in order to fix the gauze on the surface of the patient's skin wound, it needs to be wrapped in multiple layers. Therefore, during the removal process, medical staff need to have a certain level of proficiency, and the removal process is relatively cumbersome. Summary of the Invention

[0005] The object of the present invention is to provide an injection site care device for oncology care to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an injection site care device for oncology nursing, comprising a soft plate, a second groove being provided at the front end of the soft plate, cavities being provided at the left and right ends of the interior of the second groove, a fixed shaft being installed inside the two cavities, a rotating plate being rotatably connected to the surface of the fixed shaft, a gauze layer being installed between the two rotating plates at the position inside the second groove, a soft pad being slidably installed on the left and right sides of the second groove through a slide groove, a connecting rod being installed on the rear end of the soft pad, the connecting rod passing through the soft plate and extending to the rear end of the soft plate, triangular blocks being telescopically installed on the left and right ends of the connecting rod, an extrusion rod being installed on the rear end of the soft pad at the upper and lower sides of the connecting rod, the other end of the extrusion rod being in contact with the side of the rotating plate away from the groove.

[0007] Preferably, the left and right sides of the soft board are both rotatably connected to a rotating shaft, a torsion spring is provided inside the rotating shaft, and an elastic band is installed on the surface of the rotating shaft.

[0008] Preferably, a connecting block is installed at the other end of each of the two elastic straps, a card slot is provided at the front end of one connecting block, and a card block is provided at the front end of the other connecting block, and the card block and the card slot are adapted to each other.

[0009] Preferably, a first groove is provided on both upper and lower end surfaces of the connecting rod, a first spring telescopic rod is installed inside the first groove, and the other end of the first spring telescopic rod is connected to one end of the triangular block.

[0010] Preferably, the soft board is provided with a plurality of ventilation holes at the rear end of the second groove.

[0011] Preferably, two through slots are provided on both sides of the soft plate between the soft pad and the elastic strap, the internal threads of the through slots are connected with extrusion columns, and the front ends of the extrusion columns are equipped with extrusion pads.

[0012] Preferably, second spring telescopic rods are installed at the upper and lower sides of the two extrusion rods at the rear end of the soft pad, and the other ends of the two second spring telescopic rods are connected to the side walls of the internal cavity of the soft board.

[0013] Preferably, annular sealing gaskets are provided at the opening edges of both ends of the through groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The injection site care device for oncology nursing uses two elastic straps to fix the soft plate on the patient's skin surface, and then the second groove of the soft plate covers the patient's wound surface. The patient's skin will squeeze the two soft pads outward, and the two soft pads drive the connecting rod to move outward. When the two triangular blocks on the surface of the connecting rod are brought out to the outside of the soft plate, they will retract outward and get stuck on the surface of the soft plate, thereby limiting the connection rod and the soft pad. At this time, the two extrusion rods at the rear end of the soft pad will squeeze the rotating plate inward, and the rotating plate will rotate around the fixed axis. The ends of the two rotating plates away from the second groove are squeezed, and the other ends will rotate in the opposite direction, thereby driving the gauze layer to move toward the opening of the second groove until it contacts the patient's skin. At this time, the gauze layer will cover the patient's skin. When removing, only the two elastic straps need to be separated to immediately remove the soft plate and the gauze layer from the patient's skin surface. The installation and removal process is convenient and quick, and requires less user proficiency and has a wider applicability.

[0016] 2. This injection site care device for oncology nursing uses a threaded connection between an extrusion column and a through-groove. After the soft plate is covered on the patient's skin surface, the extrusion column is rotated toward the patient's skin. The squeezing of the skin by the extrusion column can increase the stability of the soft plate to a certain extent and reduce the chance of displacement of the soft plate.

[0017] 3. The injection site care device for oncology nursing can enhance the sealing effect with the extrusion column by providing annular sealing gaskets at both end openings of the through-groove, thereby preventing dust and other debris from contacting the patient's skin through the through-groove.

For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] like Figures 1 to 6As shown, the injection site care device for oncology nursing in this embodiment includes a soft plate 1, and a second groove 19 is opened at the front end of the soft plate 1. The second groove 19 is used to cover the skin wound of the patient. The left and right ends of the second groove 19 are provided with cavities, and the interiors of the two cavities are installed with fixed shafts 17. The fixed shaft 17 is fixedly installed and cannot rotate. The surface of the fixed shaft 17 is rotatably connected to a rotating plate 16. The rotating plate 16 and the fixed shaft 17 are rotatably connected. The rotating plate 16 can rotate around the fixed shaft 17 to a certain extent. A gauze layer 8 is installed between the two rotating plates 16 at a position inside the second groove 19. Under normal conditions, the gauze layer 8 is located inside the second groove 19. It should be noted that, when not in use, a sealing film needs to be set at the opening of the second groove 19 for sealing to prevent the gauze layer 8 from contacting the outside world. When in use, the sealing film is torn off. The front end of the soft plate 1 is located on the left and right sides of the second groove 19 and is slidably installed with soft pads 7 through slides. The soft pads 7 have a certain softness and are made of rubber material. The soft pads 7 can slide inside the slide. The rear end of the soft pad 7 is equipped with a connecting rod 10, which passes through the soft board 1 and extends to the rear end of the soft board 1. Triangular blocks 13 are telescopically installed at both ends of the connecting rod 10. Under normal conditions, the triangular blocks 13 will be squeezed by the surface of the soft board 1. When the soft pad 7 drives the connecting rod 10 to slide outward, the connecting rod 10 will drive the two triangular blocks 13 to move to the outside of the soft board 1. At this time, the triangular blocks 13 will pop out to the outside of the connecting rod 10. It should be noted that the outer end of the triangular block 13 is an inclined surface, and the end close to the soft board 1 is a flat surface. A squeezing rod 15 is installed at the rear end of the pad 7 on the upper and lower sides of the connecting rod 10. The other end of the squeezing rod 15 contacts the side of the rotating plate 16 away from the groove. The two squeezing rods 15 at the rear end of the soft pad 7 will squeeze the rotating plate 16 inward, and the rotating plate 16 will rotate around the fixed axis 17. The ends of the two rotating plates 16 away from the second groove 19 are squeezed, and the other ends will rotate in the opposite direction, thereby driving the gauze layer 8 to move toward the opening of the second groove 19 until it contacts the patient's skin. At this time, the gauze layer 8 will cover the patient's skin.

[0029] Specifically, the left and right sides of the soft board 1 are rotatably connected to a rotating shaft 12, and a torsion spring is provided inside the rotating shaft 12. An elastic strap 2 is installed on the surface of the rotating shaft 12. In the absence of external force, the elastic strap 2 will be wrapped around the surface of the rotating shaft 12. The other ends of the two elastic straps 2 are installed with a connecting block 3. A card slot 4 is provided at the front end of one connecting block 3, and a card block 5 is provided at the front end of the other connecting block 3. The card block 5 and the card slot 4 are adapted to each other. The user first pulls out the two elastic straps 2 outward and connects them through the card block 5 and the card slot 4, thereby connecting the two elastic straps 2 together. At this time, under the action of the torsion spring, the rotating shaft 12 will apply a reverse pulling force to the elastic strap 2, which will cause the elastic strap 2 to be further stretched, and then the elastic strap 2 will be firmly fixed to the patient's skin surface.

[0030] Furthermore, a first groove 18 is provided on the upper and lower end surfaces of the connecting rod 10, and a first spring telescopic rod 11 is installed inside the first groove 18. The other end of the first spring telescopic rod 11 is connected to one end of the triangular block 13. When the triangular block 13 is located inside the soft board 1, it will be squeezed into the inside of the first groove 18. When the triangular block 13 moves to the outside of the soft board 1, it will be ejected to the outside of the first groove 18 under the action of the first spring telescopic rod 11. At this time, the triangular block 13 will be stuck on the outside of the soft board 1. When it needs to be retracted, the triangular block 13 can be squeezed into the inside of the first groove 18 again by manual squeezing.

[0031] Furthermore, a plurality of ventilation holes 9 are provided at the rear end of the soft board 1 located at the second groove 19. The ventilation holes 9 allow the gauze layer 8 to be in contact with the outside air, thereby increasing the degree of gas circulation.

[0032] Furthermore, two through grooves 20 are provided on both sides of the soft board 1 between the soft pad 7 and the elastic band 2. The internal threads of the through grooves 20 are connected to the extrusion column 6, and the front end of the extrusion column 6 is installed with a compression pad 21. Through the threaded connection between the extrusion column 6 and the through groove 20, after the soft board 1 is covered on the patient's skin surface, the extrusion column 6 is rotated toward the patient's skin. The squeezing of the skin by the extrusion column 6 can increase the stability of the soft board 1 to a certain extent, and reduce the probability of displacement of the soft board 1. The compression pad 21 is a soft material cushion, which can reduce the patient's discomfort.

[0033] Furthermore, the rear end of the soft pad 7 is located at the upper and lower sides of the two extrusion rods 15, and second spring telescopic rods 14 are installed. The other ends of the two second spring telescopic rods 14 are connected to the side walls of the internal cavity of the soft board 1. When there is no external force, the soft pad 7 will be ejected to the front end of the soft board 1 under the action of the two second spring telescopic rods 14. When the soft pad 7 is squeezed, the two second spring telescopic rods 14 will be squeezed synchronously. In the absence of external force, the two second spring telescopic rods 14 will drive the soft pad 7 to move to the front end of the soft board 1. At the same time, external force is required to squeeze the two triangular blocks 13 so that the triangular blocks 13 are squeezed into the first groove 18 opened on the surface of the connecting rod 10. The second spring telescopic rod 14 drives the connecting rod 10 and the triangular block 13 to change position, so that the user can clearly know the usage of the device, thereby avoiding the unnecessary risk of the used device being used twice.

[0034] Furthermore, annular sealing gaskets 22 are provided at the edge positions of the openings at both ends of the through-groove 20. By providing annular sealing gaskets 22 at the openings at both ends of the through-groove 20, the sealing effect with the extrusion column 6 can be increased, preventing dust and other debris from contacting the patient's skin through the through-groove 20.

[0035] The method of use of this embodiment is as follows: the soft plate 1 is fixed to the patient's skin surface by two elastic bands 2, and the second groove 19 of the soft plate 1 is covered on the patient's wound surface. The patient's skin will squeeze the two soft pads 7 outward, and the two soft pads 7 drive the connecting rod 10 to move outward. When the two triangular blocks 13 on the surface of the connecting rod 10 are brought out to the outside of the soft plate 1, they will stretch outward and get stuck on the surface of the soft plate 1, thereby limiting the connection rod 10 and the soft pad 7. At this time, the two squeezing rods 15 at the rear end of the soft pad 7 will squeeze inward. The rotating plate 16 rotates around the fixed axis 17, and one end of the two rotating plates 16 away from the second groove 19 is squeezed, and the other end rotates in the opposite direction, thereby driving the gauze layer 8 to move toward the opening of the second groove 19 until it contacts the patient's skin. At this time, the gauze layer 8 will cover the patient's skin. When disassembling, you only need to separate the two elastic straps 2, and immediately remove the soft plate 1 and the gauze layer 8 from the patient's skin surface. The installation and disassembly process is convenient and quick, and has low requirements on the user's proficiency and wider applicability.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalent features for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
