DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown;

[0025] A spill-proof nursing dressing changer comprises a spill-proof cover 1 and a medicine barrel 2. A sealing cylinder 3 connected to the medicine barrel 2 is passed through the middle of the spill-proof cover 1. A pressurizing assembly 4 is provided on the top of the sealing cylinder 3, and a medicine injection hole 5 is provided in the middle of the sealing cylinder 3. A liquid leakage plate 6 is provided at the bottom of the medicine barrel 2, and a sealing plate 7 is tightly attached to the liquid leakage plate 6. A limiting rod 8 is provided at the bottom of the spill-proof cover 1, and a tension spring 9 is provided between the top of the medicine barrel 2 and the top inner of the spill-proof cover 1.

[0026] It should be noted that: in this embodiment, a vent is provided on the overflow cover 1 to prevent the internal air pressure from increasing during use. The function of the tension spring 9 can achieve the purpose of squeezing the sealing cylinder 3 downward while driving the overflow cover 1 to fit tightly against the patient's skin, thereby ensuring the reliability of the overflow prevention effect.

[0027] In this embodiment, by providing a pressurizing component 4, the medicine cartridge 2 can be pressurized, thereby ensuring that the medicine is stably sprayed out from the leakage plate 6, and by the cooperation of the sealing plate 7 and the limiting rod 8, the controllability of the spraying timing can be achieved. In addition, the overflow cover 1 can prevent the medicine from overflowing, thereby ensuring the uniformity and stability of the medicine spraying.

[0028] In an optional embodiment, the bottom end of the overflow shield 1 is detachably provided with a sealing rubber ring 10, which can ensure a closer fit with the patient's skin and improve comfort.

[0029] like Figure 3 and Figure 4 As shown;

[0030] In an optional embodiment, a first guide groove 11 is provided on the sealing cylinder 3, and a first guide block 12 that cooperates with the first guide groove 11 is provided on the top inner side of the overflow prevention cover 1, so as to prevent the sealing cylinder 3 from rotating.

[0031] In an optional embodiment, the pressurizing assembly 4 includes a knob 401 rotatably connected to the medicine barrel 2 , a screw 402 is screwed to the middle of the knob 401 , and a sealing plug 403 is provided at the bottom of the screw 402 to seal against the inner wall of the medicine barrel 2 .

[0032] In this embodiment: the knob 401 is turned, and the knob 401 drives the screw 402 to descend. The screw 402 squeezes the air inside the sealing cylinder 3 through the sealing plug 403, thereby pressurizing the medicine barrel 2. The initial position of the sealing plug 403 is above the injection hole 5. When the sealing plug 403 moves to the bottom of the injection hole 5, the air inside the sealing cylinder 3 can be squeezed.

[0033] like Figure 5 As shown;

[0034] In an optional embodiment, a limiting ring 13 is provided on the inner side of the top of the medicine barrel 2, a second guide groove 14 is provided on the screw 402, and a second guide block 15 is provided on the inner side of the limiting ring 13 to cooperate with the second guide groove 14. This ensures that when the knob 401 is turned, the screw 402 can only be raised and lowered but not rotated.

[0035] like Figure 6 As shown;

[0036] In an optional embodiment, leakage holes 16 are evenly opened on the leakage plate 6, and hemispherical sealing blocks 17 corresponding to the leakage holes 16 are provided on the sealing plate 7, and the leakage plate 6 and the sealing plate 7 are connected by an elastic member 18.

[0037] In an optional embodiment, the limiting rod 8 is provided with a plurality of squeezing columns 19 aligned with the leakage holes 16 .

[0038] In this embodiment, when the sealing cylinder 3 drives the medicine barrel 2 to descend, the squeezing column 19 extends into the leakage hole 16 and squeezes the sealing block 17 until the sealing block 17 leaves the leakage hole 16, and the leakage hole 16 is unsealed. At this time, the compressed gas inside the medicine barrel 2 sprays the medicine through the leakage hole 16.

[0039] The working principle and usage process of the present invention are as follows: first, the medicine that needs to be replaced is injected into the medicine barrel 2 through the medicine injection hole 5, and the knob 401 is turned. The knob 401 drives the screw 402 to descend, and the screw 402 squeezes the air inside the sealing cylinder 3 through the sealing plug 403, thereby pressurizing the medicine barrel 2. The device is placed at the position of the medicine that needs to be replaced and the sealing cylinder 3 is pressed. The sealing cylinder 3 drives the medicine barrel 2 to descend. At the same time, the extrusion column 19 extends into the leakage hole 16 and squeezes the sealing block 17 until the sealing block 17 leaves the leakage hole 16. At this time, the compressed gas inside the medicine barrel 2 sprays the medicine through the leakage hole 16, loosens the sealing cylinder 3, and the elastic member 18 drives the sealing plate 7 to reset and uses the sealing block 17 to seal the leakage hole 16. At this time, the medicine changing process is completed.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is 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 replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
