Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

As shown in fig. 1 to 3, an injection medical and beauty instrument comprises a syringe needle cylinder 1 and a male joint 11 communicated with the syringe needle cylinder 1, wherein the male joint 11 is connected with a needle head 2, the needle head comprises a female joint 21 and a blunt needle body 22 which are integrally connected, one side of the blunt needle body 22 far away from the female joint 21 is provided with a blunt needle head 23, and one side of the blunt needle body close to the blunt needle head 23 is also uniformly provided with liquid injection holes 24; when the puncture needle is used, injection can enter the skin through the injection hole, and the resistance in the puncture process can be reduced through the blunt needle head arranged at the top end, so that the movement direction of puncture positioning is ensured; but the blunt needle has higher toughness, so the puncture positioning effect is poor;

in order to solve the problem, the blunt needle body 22 can be further sleeved with a baffle 3, namely, the lower part of the baffle 3 is provided with a through hole for penetrating the blunt needle body 22, when in use, the blunt needle body can penetrate through the through hole, in addition, a flexible part 4 is connected and arranged between the baffle 3 and the female joint 21, when in use, the puncture position of the blunt needle is adjusted through the cooperative fit of the blunt needle body and the baffle, and the needle has better positioning effect while keeping the advantages of convenience, rapidness, no trace, no pain and the like of common blunt needle injection;

furthermore, the sharp needle head 5 is fixedly arranged above the through hole, and the sharp needle head 5 is a triangular pyramid, so that the sharp needle head and the blunt needle head are integrated, the use is more convenient, the number of instruments used in common operation can be reduced, particularly, the sharp needle is prevented from being repeatedly used, and the use cost is improved;

furthermore, considering that when the sharp needle is used for puncturing holes, the sharp needle is too short and is not convenient to operate, a slotted hole 7 can be formed in one side of the baffle plate 3 close to the syringe needle cylinder 1, the size of the slotted hole 7 is the same as that of the blunt needle head 23, and the central line of the slotted hole 7 is superposed with that of the sharp needle head 5; when in use, the blunt needle head is inserted into the slotted hole, which is equivalent to using the blunt needle body and the syringe tube as a lengthened handle rod, thereby facilitating the operation;

furthermore, because the toughness of the blunt needle is relatively high, a certain lateral or downward pressure is often generated during operation, and the connection reliability of the connector is considered, the outer side surface of the male connector 11 is provided with an external thread, the inner side surface of the female connector 21 is provided with an internal thread, and the internal thread and the external thread are meshed with each other during connection;

when the device is used, a blunt needle body is firstly screwed on a male connector through a female connector, then the blunt needle head is inserted into a slot hole, one hand controls a baffle, the other hand controls an injector, so that the operation of opening a hole on human skin can be conveniently carried out, after an orifice is formed on the human skin, the blunt needle head leaves the slot hole and penetrates into a through hole, the baffle is sleeved on the blunt needle body, then the advancing direction and the positioning of the blunt needle body can be flexibly controlled through the baffle until the blunt needle body reaches a preset position, and then injection is injected into the skin; because the sharp needle head is sharp, a protective cover 6 can be covered on the sharp needle head 5 for safety, the lower end of the protective cover 6 is hinged with the baffle 3, and the maximum diameter of the protective cover 6 is smaller than that of the through hole; like this when using sharp syringe needle, in the protective cover can rotate embedding through-hole, when using blunt syringe needle, blunt syringe needle body can be with protective cover jack-up and spacing, plays the effect of protection.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
