Embodiment 1

[0053] see Figure 1-11 , a self-alignment needle holder, comprising a self-alignment needle holder 1 and a needle body 2 installed in the self-alignment needle holder 1, both ends of the needle body 2 are provided with needle injection fronts inclined in the same direction 201, see figure 1 with image 3 , the left and right ends of the self-alignment needle holder 1 are fixedly connected with a plurality of cylindrical friction strips 103 , and the lower end of the self-alignment needle holder 1 is fixedly connected with a plurality of screw buckles 102 . The cylindrical friction strip 103 increases the friction between the self-alignment needle holder 1 and the assembly worker's fingers, which is convenient for the assembler to hold the self-alignment needle holder 1, improves the practicability of the self-alignment needle holder 1, and the spiral The buckle 102 can increase the connection strength between the self-alignment needle base 1 and the syringe, effectively pre...

Embodiment 2

[0057] see Figure 1-11 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 7 with Figure 10 , the outer end of the telescopic support sleeve 7 is fixedly connected with a plurality of magnetic particle columns 701, and the magnetic poles carried by the magnetic particle columns 701 on the upper and lower sides are opposite magnetic poles. When the telescopic support sleeves 7 on the upper and lower sides are close to each other, the magnetic particle column 701 generates a mutual magnetic force, which makes the telescopic support sleeve 7 elongate, increases the pressing force between the flexible locking suction cups 8, and then improves the adsorption of the flexible locking suction cups 8 Strength, increased locki...

Embodiment 3

[0059] see Figure 1-11 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to figure 2 , a method for using a self-alignment needle seat, comprising the following steps:

[0060] S1. The assembler inserts any end of the needle body 2 into the self-alignment hole 104 of the needle;

[0061] S2. Then shake the self-aligning needle seat 1 slightly by hand, and the needle body 2 will be automatically aligned under the guidance of the direction guiding slope 301, so that the injection front 201 of the needle is consistent with the needle direction indicating port 101;

[0062] S3. The assembler then presses the needle body 2 by hand, so that the needle body 2 squeezes the locking and pressing column 3, and the pressure bag lever 6 s...

Abstract

The invention discloses a self-alignment type needle seat and a use method thereof, belongs to the field of medical appliances, and is suitable for anesthetic needles, in particular to spinal anesthetic needles. The self-alignment type needle seat comprises a self-alignment type needle seat body and a needle head body installed in the self-alignment type needle seat body, and needle head injection front faces inclined in the same direction are arranged at the two ends of the needle head body; through the cooperation of the direction guiding inclined plane and the needle direction indicating port, the needle body can be effectively and autonomously aligned, an assembling worker is assisted to judge the injection front face position of the needle, the step that the assembling worker recognizes the injection front face of the needle with naked eyes is omitted, manpower input is reduced, the production cost is reduced, and the production efficiency is improved; according to the self-alignment type needle seat, the self-alignment type needle seat is simple in structure and convenient to use, the economic benefit of a medical instrument manufacturer is improved, the aligned needle head body can be fixed through cooperation of the locking and pressing embedded column and the needle locking air bag ring, the follow-up bonding difficulty of the needle head body is reduced, and the functionality of the self-alignment type needle seat is improved.

Description

technical field [0001] The invention relates to the field of medical appliances, and more specifically relates to a self-alignment needle holder and a method of use thereof, which are suitable for anesthesia needles, especially spinal anesthesia needles. Background technique [0002] The needle is a hollow metal needle tube that can be freely loaded and unloaded for injecting medicine or extracting liquid in the medical field. The process of withdrawing and injecting gas or liquid with a needle is called injection. The needle head is generally fixedly installed on the needle seat, and is used to connect storage devices such as a syringe, and the fixing method of the needle head and the needle seat is generally glued. The needle is mainly used on the syringe, and is connected to the syringe barrel through the needle seat. [0003] With the continuous advancement of medical technology, the current medical needles are gradually diversified, not only sticking to the connection...
