Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically an alcohol spraying device. Background Technology

[0002] The main stimulation areas for warm needling moxibustion are body acupoints and Ashi points. First, select a filiform needle longer than 1.5 inches, insert it into the acupoint to obtain the Qi sensation, and during needle retention, wrap the needle handle with either a pure moxa wool ball or a section of moxa stick about 2cm long, placing it on the needle handle. Regardless of whether it's a moxa wool ball or a moxa stick section, it should be 2-3cm away from the skin before igniting it from the lower end. If the patient feels unbearably hot during the burning process, a piece of stiff paper can be placed in the acupoint area to slightly reduce the heat. Each session can consist of 3-4 moxa wool balls or 1-2 moxa stick sections. In recent years, cap-shaped moxa cones have also been used for warm needling moxibustion.

[0003] The procedure for warm needle acupuncture is as follows: cut the moxa stick into multiple sections using a simple tool, then use a punching device to punch a hole in the middle of the end of each section, spray an appropriate amount of alcohol on the other end, insert the tip of the acupuncture needle into the hole in the moxa stick, then ignite the end that was sprayed with alcohol, and then use tweezers with a cloth strip fixed to one side of the tweezers that is close to the other. After the cloth strip is wetted, intermittently clamp the outer surface of the acupuncture needle to cool it down. After the moxa stick has burned out, the ash at the tip of the acupuncture needle needs to be removed.

[0004] Currently, syringes are mostly used as spraying tools in practical operation. During the spraying process, it is necessary to maintain a distance and spray as much as possible on most of the area at the end of the moxibustion column. Syringes without needles have a large liquid output, which is easy to spray and causes liquid waste. In order to ensure the uniformity of liquid output, the needle is retained for use, which poses a certain safety risk. Utility Model Content

[0005] The technical problem to be solved by this utility model is: In the current warm needle acupuncture process, a syringe is used as a tool to spray alcohol on the cut-off small sections of moxibustion column. If the needle is retained, the liquid output is slow, which increases the operation time and safety risks. If only the syringe is used, the liquid output is large and difficult to control, resulting in liquid waste.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An alcohol spraying device includes a syringe body, the syringe body including a syringe barrel and a piston rod disposed inside the syringe barrel for use therewith, and a detachable nozzle assembly is embedded at the bottom of the syringe barrel;

[0008] The nozzle assembly includes a top cover and a bottom cover that cooperate with each other and are arranged from top to bottom. The inner surfaces of the top cover and the bottom cover form a transition cavity. The top of the top cover is fixedly connected to a connector communicating with the transition cavity at its central axis position. The bottom of the bottom cover is fixedly connected to a support leg at its central axis position. A ball head is fixedly connected to the end of the support leg away from the bottom cover.

[0009] The outer surface of the bottom cover has several liquid outlet holes spaced circumferentially near the support feet.

[0010] Furthermore, a throttling core is installed inside the transition cavity, and a screw is fixedly connected to the bottom of the throttling core at the position of the central axis. A screw hole that matches the screw is opened at the bottom of the inner surface of the bottom cover at the position of the screw. The gap between the outer surface of the throttling core and the inner wall of the transition cavity decreases sequentially from the connector to the liquid outlet.

[0011] Furthermore, the angle between the liquid outlet and the central axis of the bottom cover is less than 30 degrees.

[0012] Working principle and beneficial effects: By using an existing syringe with a nozzle assembly embedded at its bottom, the nozzle assembly includes a mating top cover and a bottom cover. The bottom cover has a ball-headed support leg for support and to prevent punctures. In use, the support leg is placed at the center of the cut-off moxibustion column end. The liquid squeezed by the syringe enters the transition chamber and is sprayed out from several circumferentially spaced outlet holes, completing the spraying work in one go. This solves the problems of existing technologies. The spray assembly is detachable and can be used with other syringes for recycling. The angle between the outlet hole and the central axis of the bottom cover is less than 30 degrees, which reduces the amount of alcohol sprayed out of the outer side of the moxibustion column.

[0018] like Figure 1 As shown, Example 1,

[0019] An alcohol spraying device includes a syringe body, which includes a syringe barrel 1 and a piston rod 2 disposed within the syringe barrel 1 and used therewith. A detachable nozzle assembly is embedded in the bottom of the syringe barrel 1. The nozzle assembly includes a top cover 3 and a bottom cover 4 that cooperate with each other and are arranged from top to bottom. The inner surfaces of the top cover 3 and the bottom cover 4 form a transition cavity. A connector 5 communicating with the transition cavity is fixedly connected to the top of the top cover 3 at its central axis position. A support leg 6 is fixedly connected to the bottom of the bottom cover 4 at its central axis position. A ball head is fixedly connected to the end of the support leg 6 away from the bottom cover 4. Several liquid outlet holes 7 are circumferentially spaced on the outer surface of the bottom cover 4 near the support leg 6. This device utilizes existing syringes. A nozzle assembly is embedded at its bottom, comprising a top cover 3 and a bottom cover 4 that cooperate with each other. The bottom cover 4 has a ball-headed support leg 6, which can be used for support and also prevents punctures. When in use, the support leg 6 is supported at the center of the cut-off moxibustion column end. Then, the syringe body is squeezed to squeeze the alcohol into the transition cavity formed by the inner surfaces of the top cover 3 and the bottom cover 4, and spray it out from the liquid outlet 7. The spraying work can be completed in one go, which can solve the problems of the existing technology. The spray assembly is detachable and can be used with other syringes. It can be reused. The angle between the liquid outlet 7 and the central axis of the bottom cover 4 is less than 30 degrees, which can reduce the amount of alcohol sprayed out of the outer side of the moxibustion column.

[0020] like Figure 2As shown, in order to control the amount of liquid ejected from the liquid outlet 7 and ensure that a similar amount of liquid can be ejected from multiple liquid outlets 7, Embodiment 2 is provided. The specific structure is as follows: a throttling core 8 is installed in the transition cavity. A screw is fixedly connected to the bottom of the throttling core 8 at the position of the central axis. A screw hole is opened at the bottom of the inner surface of the bottom cover 4 at the position of the screw. The gap between the outer surface of the throttling core 8 and the inner wall of the transition cavity decreases sequentially from the position of the connector 5 to the position of the liquid outlet 7. The function of the throttling core 8 is to increase the resistance of the liquid squeezed into the transition cavity, increase the pressure of the liquid in the transition cavity, and ensure that a similar amount of liquid can be ejected from multiple liquid outlets 7.
