Description

Technical Field

[0001] The invention relates to medical instruments, in particular to a water light needle for reducing bleeding and a water light needle injection method for reducing bleeding. Background Art

[0002] Adults' facial skin is prone to sagging, wrinkles, and large pores. These problems can be improved by injecting drugs into the dermis, thereby achieving hydrated, tender, wrinkle-reducing, and firming facial skin. The current mainstream water-light needle is mainly combined with negative pressure technology. Before entering the skin, the water-light needle uses negative pressure to lift the skin, and then the needle accurately enters the dermis to inject the drug.

[0003] During the existing hyaluronic acid injection process, there is bleeding in the treatment area, which is mainly caused by two aspects: at the end of the injection, there is a negative pressure in the negative pressure chamber, which is lower than the subcutaneous pressure, causing blood to flow out of the skin surface; at the end of the injection, the negative pressure disappears slowly, resulting in slow removal of the needle and more likely to form a wound. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a hyaluronic acid injection that can reduce bleeding in the treatment area.

[0005] In order to overcome the deficiencies of the prior art, a second object of the present invention is to provide a method for hyaluronic acid injection that can reduce bleeding in the treatment area.

[0006] One of the purposes of the present invention is achieved by the following technical solution:

[0007] A hyaluronic acid needle for reducing bleeding comprises a negative pressure chamber and a needle installed in the negative pressure chamber, the negative pressure chamber is provided with an air inlet and an air outlet, the hyaluronic acid needle for reducing bleeding also comprises an air supply device, an air suction device and an air pipe, the air supply device is connected with the air inlet through the air pipe, the air suction device is connected with the air outlet through the air pipe, when injection is performed, the air suction device forms a negative pressure in the negative pressure chamber, lifts the skin and allows the needle to penetrate the skin; when the injection is completed, the pressure inside the negative pressure chamber increases rapidly, allowing the needle to be quickly pulled out of the skin and the high pressure inside the negative pressure chamber stops the bleeding of the skin.

[0008] Furthermore, when injection is performed, the extraction unit flow rate of the air suction device to the negative pressure chamber is higher than the air supply unit flow rate of the air supply device to the negative pressure chamber, so that negative pressure is formed in the negative pressure chamber.

[0009] Furthermore, when the injection is completed, the extraction unit flow rate of the vacuum device to the negative pressure chamber is reduced, and the air supply unit flow rate of the air supply device to the negative pressure chamber is increased, so that the pressure inside the negative pressure chamber is rapidly increased.

[0010] Furthermore, the cross-section of the negative pressure chamber is any one of rectangular, circular, and triangular.

[0011] Furthermore, the hyaluronic acid needle for reducing bleeding also includes a pressure sensor, which is installed in the negative pressure chamber and measures the air pressure in the negative pressure chamber.

[0012] Furthermore, the negative pressure chamber is provided with a side wall, the air inlet and the air outlet are arranged on the side wall, and the air inlet and the air outlet are arranged opposite to each other.

[0013] The second object of the present invention is achieved by adopting the following technical solution:

[0014] A method for reducing bleeding by injection of water light needles comprises the following steps:

[0015] Place the negative pressure cavity of the water light needle close to the skin of the treatment area;

[0016] The vacuum device creates negative pressure in the negative pressure chamber, lifts the skin and allows the needle to penetrate the skin for injection;

[0017] After the injection is completed, the pressure inside the negative pressure chamber increases rapidly, causing the needle to be quickly pulled out of the skin and the high pressure inside the negative pressure chamber stops the bleeding of the skin.

[0018] Furthermore, when injection is performed, the extraction unit flow rate of the air suction device to the negative pressure chamber is higher than the air supply unit flow rate of the air supply device to the negative pressure chamber, so that negative pressure is formed in the negative pressure chamber.

[0019] Furthermore, when the injection is completed, the extraction unit flow rate of the vacuum device to the negative pressure chamber is reduced, and the air supply unit flow rate of the air supply device to the negative pressure chamber is increased, so that the pressure inside the negative pressure chamber is rapidly increased.

[0020] Compared with the prior art, the hyaluronic acid needle for reducing bleeding of the present invention also includes an air supply device, an air suction device and an trachea. The air supply device is connected to the air inlet through the trachea, and the air suction device is connected to the air outlet through the trachea. When injecting, the air suction device forms a negative pressure in the negative pressure chamber, lifts the skin and allows the needle to penetrate the skin; when the injection is completed, the pressure inside the negative pressure chamber increases rapidly, allowing the needle to be quickly pulled out of the skin and the high pressure inside the negative pressure chamber stops the bleeding of the skin.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be another intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Figures 1 to 3 The schematic diagram of the water light needle for reducing bleeding is used to inject medicine into the skin 8 to improve the problems of sagging skin 8, wrinkles, enlarged pores, etc. The water light needle for reducing bleeding includes a negative pressure chamber 1, a needle 2, an air supply device 5, an air extraction device 6 and two air tubes 7.

[0029] The negative pressure chamber 1 is a hollow structure, and the inside of the negative pressure chamber 1 is used to install the needle 2. The negative pressure chamber 1 is provided with side walls, and the side walls form a hollow cavity. One side of the hollow cavity is designed to be open, which is convenient for the negative pressure chamber 1 to fit the skin 8. Specifically, the cross-section of the negative pressure chamber 1 is any one of a rectangle, a circle, and a triangle. In other embodiments, the cross-section of the negative pressure chamber 1 can also be other shapes. The negative pressure chamber 1 is made of elastic material, so that the negative pressure chamber 1 feels better when it fits the skin 8. The negative pressure chamber 1 is provided with an air inlet 3 and an air outlet 4, the air inlet 3 is used to inflate the negative pressure chamber 1, and the air outlet 4 is used to extract air from the negative pressure chamber 1. The air inlet 3 and the air outlet 4 are arranged on the side wall and are arranged opposite to each other.

[0030] The needle 2 is used to inject medicine into the skin 8. There are multiple needles 2, and the multiple needles 2 are evenly arranged inside the negative pressure chamber 1. Specifically, the needle 2 is a micro needle, and the diameter of the pinhole of the needle 2 is reduced. In this embodiment, there are 6 needles 2, and the 6 needles 2 are arranged in two rows.

[0031] The air supply device 5 is an air supply pump, which is connected to the air inlet 3 through the air pipe 7. The air supply device 5 inputs gas into the negative pressure chamber 1 through the air inlet 3 to adjust the air pressure in the negative pressure chamber 1.

[0032] The air extraction device 6 is an air extraction pump, which is connected to the air outlet 4 through the air pipe 7. The air extraction device 6 extracts gas from the negative pressure chamber 1 through the air outlet 4 to adjust the air pressure in the negative pressure chamber 1.

[0033] The air pipe 7 is used for allowing gas to flow to form an air path.

[0034] When assembling the water light needle for reducing bleeding, the air supply device 5 is connected to the air inlet 3 of the negative pressure chamber 1 through the air pipe 7. The air extraction device 6 is connected to the air outlet 4 of the negative pressure chamber 1 through the air pipe 7. The needle 2 is installed in the negative pressure chamber 1.

[0035] When using the hyaluronic acid needle to reduce bleeding, the negative pressure chamber 1 is attached to the skin 8 of the treatment area, and the unit flow rate of extraction of gas in the negative pressure chamber 1 by the vacuum device 6 is higher than the unit flow rate of gas supply to the negative pressure chamber 1 by the air supply device 5, so a negative pressure is formed inside the negative pressure chamber 1. When the negative pressure reaches a certain value, the skin 8 will be lifted, so that the needle 2 will be inserted into the skin 8, and then the liquid will be injected; when the injection is completed, the unit flow rates of the air supply device 5 and the vacuum device 6 are adjusted, so that the unit flow rate of gas supply of the air supply device 5 is rapidly increased, and the extraction unit flow rate of the vacuum device 6 is rapidly reduced, so as to ensure that the pressure inside the negative pressure chamber 1 is rapidly increased. On the one hand, it prompts the needle 2 to be pulled out of the skin 8 at a faster speed, and on the other hand, the higher pressure in the negative pressure chamber 1 has a hemostatic effect.

[0036] The present application also relates to a method for injecting a water light needle, comprising the following steps:

[0037] Place the negative pressure chamber 1 of the water light needle close to the skin of the treatment area 8;

[0038] The vacuum device forms negative pressure in the negative pressure chamber 1, lifts the skin 8 so that the needle 2 pierces the skin 8 for injection;

[0039] After the injection is completed, the pressure inside the negative pressure chamber 1 increases rapidly, so that the needle 2 is quickly pulled out of the skin 8 and the high pressure inside the negative pressure chamber 1 stops the bleeding of the skin 8 .

[0040] Furthermore, during injection, the extraction unit flow rate of the gas in the negative pressure chamber 1 by the air extraction device 6 is higher than the gas delivery unit flow rate of the gas delivery device 5 to the negative pressure chamber 1, thereby forming a negative pressure inside the negative pressure chamber 1. When the injection is completed, the unit flow rates of the gas delivery device 5 and the air extraction device 6 are adjusted so that the gas delivery unit flow rate of the gas delivery device 5 increases rapidly and the extraction unit flow rate of the air extraction device 6 decreases rapidly, thereby ensuring that the pressure inside the negative pressure chamber 1 increases rapidly.

[0041] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
