Embodiment 1

[0033] Example 1 ,Such as figure 1 As shown, the structure diagram of the first embodiment of the multi-needle suction injection needle of the present invention is given, which is composed of a body 1, a sealing plate 2, a limiting plate 3, and a plurality of injection needles 4; figure 2 , image 3 and Figure 4 The front view, rear view and right view of the ontology are given respectively, Figure 5 gives figure 2 The cross-sectional view of the A-A section in the middle, Figure 6 , Figure 7 and Figure 8 The front view, back view and left side view of the sealing plate are given respectively, Figure 9 and Figure 10 The front view and left view of the limit plate are given respectively.

[0034] The two ends of the main body 1 shown are open, the center is a partition 5, and the two sides of the partition 5 respectively form a negative pressure chamber 7 and an injection chamber 8. A plurality of injection needles 4 are evenly fixed on the partition 5, and t...

Embodiment 2

[0040] Example 2 ,Such as Figure 11 As shown, the structure schematic diagram of the second embodiment of the multi-needle adsorption injection needle of the present invention is given, Figure 12 and Figure 13 The front view and rear view of the main body 1 in this embodiment are respectively given, Figure 14 gives Figure 12 The cutaway view of the B-B section in the middle, Figure 15 A schematic diagram of the structure of the limiting plate 3 in this embodiment is given, Figure 16 A schematic structural diagram of the sealing plate 2 in this embodiment is given.

[0041] In order to avoid that the medicine flowing out from the medicine feeding tube 13 is directly ejected from the injection needle 4, when two or more injection needles 4 are used, it should be ensured that the outlet of the medicine feeding tube 13 and all the injection holes 11 on the dividing plate 5 All are not relative to further ensure the uniform injection of the drug.

[0042] In this embod...

Embodiment 3

[0043] Example 3 ,Such as Figure 17 As shown, the structure diagram of the third embodiment of the multi-needle adsorption injection needle of the present invention is given, except that an injection needle 4 is arranged on the partition 5 and a needle hole 10 is opened on the limiting plate 3 , the rest of the structure is the same as in Example 1. Since one injection needle 4 is used, the outlet of the drug inlet tube 13 and the injection hole 11 on the dividing plate 5 can be aligned, so as to realize the smooth injection of the drug. The adsorption injection needle of this embodiment is suitable for safe administration and treatment of small-area lesions due to the use of one injection needle 4 .

[0044] The use process of the multi-needle suction injection needle of the present invention is as follows:

[0045] First, liquid medicine is injected into the injection needle 4 through the syringe joint 14, and the air in the medicine feeding tube 13, the medicine chambe...

Abstract

The invention relates to a multi-syringe-needle adsorption injection needle. The multi-syringe-needle adsorption injection needle comprises a needle body, a partitioning plate is arranged in the center of the needle body, and the two ends of the needle body are open. The multi-needle-head adsorption injection needle is characterized in that a sucking negative pressure cavity and an injection cavity are formed in the two sides of the partitioning plate respectively, one or more injection syringe needles are evenly fixed to the partitioning plate and extends/extend into the sucking negative pressure cavity, and an air sucking opening is formed in the needle body and communicated with the sucking negative pressure cavity. A seal plate is arranged inside the injection cavity, a medicine cavity is formed by the seal plate and the partitioning plate, a medicine inlet tube used for injecting medicine into the medicine cavity is arranged on the seal plate, and injection holes are formed in the partitioning plate and used for being communicated with the medicine cavity and the injection syringe needles. In the using process, the liquid medicine is injected to empty air, in this way, the sucking negative pressure cavity is attached to the region to be treated, the injection syringe needles are punctured by a fixed depth through negative pressure, and treatment is completed after the medicine is pushed. Through the multiple syringe needles, large-area even and safe dosing can be achieved, the depth of the part, extending into the nidus, of the injection needle can be accurately controlled, dosing treatment is achieved at the fixed-depth position, and the multi-syringe-needle adsorption injection needle has obvious advantages and is suitable for application and popularization.

Description

technical field [0001] The present invention relates to a multi-needle absorption injection needle, more specifically, to a multi-needle absorption injection needle capable of realizing large area of ​​lesion, fixed depth safety and uniform drug delivery. Background technique [0002] In the treatment of some diseases, it is necessary to inject drugs in a large area at the same time, such as the drug injection treatment of body odor, capillary hemangioma and other diseases, it is necessary to inject the patient's armpit area at the same time, and the needle cannot be inserted at the same time If it is too deep, otherwise it will injure the patient's brachial plexus, and in severe cases, the patient will lose the mobility of the arm, or even the motor function of the entire upper limb, which is not worth the candle. [0003] In the drug injection treatment, the doctor's precise injection ability is used to inject the drug into the subcutaneous superficial tissue of the patie...
