Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 5, the present disclosure provides a floating needle feeder with an erroneous touch prevention function, including a housing, a button 7, a firing mechanism, a knob 8, and a floating needle holder 3. The housing is divided into two parts, namely an upper shell 2 and a base 1, the length of the base 1 is longer than that of the upper shell 2, so that the upper shell 2 is mounted on the rear half part of the base 1 to jointly form a closed hand-held part, and the front half part of the base 1 is in an open structure to form a needle feeding part.
A button 7 is mounted on one side of the hand-held part, and a firing mechanism controlled by the button 7 is mounted inside the hand-held part. The float seat 3 comprises two parts, one part is a fixed groove 3.3 for loading the float needle 100 in the needle feeding part to realize the firing of the float needle, and the other part is a rear rod 3.1 for receiving a firing mechanism and controlling a knob 8 in the hand-held part. The rear rod 3.1 and the fixing groove 3.3 are integrally formed. The fixing groove 3.3 is an open groove for more convenient placement of the floating needle 100 and more convenient removal of the floating needle 100.
As shown in fig. 5, the knob 8 is rotatably mounted at the rear end of the hand-held portion of the housing, and the knob 8 includes a knob portion 8.3 located outside the hand-held portion, a shaft portion 8.2 located inside the hand-held portion, and a stopper portion 8.1 located at an end of the shaft portion 8.2.

In the locked state, the firing mechanism cannot complete the firing operation even after the button 7 is pressed. After the limiting part 8.1 is positioned in the axial groove 3.6, the floating needle seat 3 and the knob 8 form an unlocking state, and the rear rod 3.1 can move forwards. In the unlocked state, after the button 7 is pressed, the firing mechanism completes the firing operation, and the floating needle 100 is ejected a certain distance to penetrate into subcutaneous tissue. With the structure, the needle feeder has the function of preventing false touch.
In order to improve the security of the locked condition, the limit stop 8.1 comprises a rubber sleeve arranged outermost, which forms an interference fit with the circumferential groove 3.5 and which forms a clearance fit with the axial groove 3.6. After the limit part 8.1 is matched with the circumferential groove 3.5, due to interference fit, the limit part 8.1 forms a relatively tight matching relationship with the circumferential groove 3.5 under the action of the rubber sleeve, and the knob 8 can be separated from the circumferential groove 3.5 by relatively large external force. And after the limit part 8.1 is separated from the circumferential groove 3.5, the clearance fit is adopted with the axial groove 3.6, so that the firing of the floating needle seat 3 is not affected.
The utility model also provides a firing mechanism, which comprises a limiting plate 6; the limiting plate 6 is transversely and slidably arranged on the inner side of the position where the button 7 is arranged so as to control the firing of the floating needle stand 100. The shell is internally provided with an abutting part 1.1, a rear rod 3.1 is provided with a thick diameter section 3.2, a firing elastomer 5 is arranged between the thick diameter section 3.2 and the abutting part 1.1, and the firing elastomer 5 is a spring which is sleeved on the rear rod 3.1, so that the floating needle seat 3 has a forward firing trend. When the limiting plate 6 is at the first transverse position, the front end face of the thick-diameter section 3.2 is overlapped with the limiting hole 6.1 on the limiting plate 6 to form limiting, and when the limiting plate 6 is at the second transverse position, the front end face of the thick-diameter section 3.2 is completely positioned in the limiting hole 6.1 to release limiting. The push button 7 is pressed to drive the limiting plate 6 from the first lateral position to the second lateral position.
In order to realize the reset of the limiting plate 6, a reset elastic body 4 is arranged between the other side of the limiting plate 6 far away from the button 7 and the inner wall of the shell, and the reset elastic body 4 is a shrapnel or a spring, so that the limiting plate 6 has a trend of moving from the second transverse position to the first transverse position.
In order to limit the floating needle seat 100 before and after the firing, as a limiting mode, the shell is provided with a first limiting part 1.2 positioned in front of the limiting plate 6, after the rear end of the fixing groove 3.3 contacts the first limiting part 1.2, the floating needle seat 3 reaches the maximum distance of backward movement, and after the front end of the thick-diameter section 3.2 contacts the first limiting part 1.2, the floating needle seat 3 reaches the maximum distance of forward movement. That is, with this structure, the front and rear limiting actions of the float seat 3 are achieved by the first limiting portion 1.2.
As another limiting form, the shell is provided with a first limiting part 1.2 positioned in front of the limiting plate 6 and a second limiting part 1.3 positioned in front of the first limiting part 1.2, after the rear end of the fixing groove 3.3 contacts the first limiting part 1.2, the floating needle seat 3 reaches the maximum distance of backward movement, and after the front end of the fixing groove 3.3 contacts the second limiting part 1.3, the floating needle seat 3 reaches the maximum distance of forward movement. No matter what kind of limiting mode is adopted, the specific setting position of the related structure needs to be set according to the moving distance of the floating needle seat 3, which belongs to the prior art and is not repeated.
In order to satisfy the movement of the rear rod 3.1, the related structures are provided with avoidance holes.
Principles and operation of the present utility model
As shown in fig. 3 and 4, initially, the knob 8 and the float 3 are in a locked state, at which time the float 100 is put into the fixing groove 3.3, and then the knob 8 is rotated to one side to be in an unlocked state with the float 3. After the symptom site is determined, the end of the needle feeding part is aligned to the symptom site. Then, the button 7 is pressed, the limiting plate 6 transversely moves to ensure that the end face of the thick-diameter section 3.2 is not overlapped with the limiting hole 6.1 any more, so that the floating needle seat 3 is rapidly and forwards ejected under the action of the triggering elastic body 5, and the steel needle of the floating needle 100 is penetrated into the skin. This process is completed in an extremely short time, and thus the pain of the patient can be reduced to some extent. After the needle 100 is pierced, the needle feeder is moved downward to disengage from the needle 100, and the needle 100 is left at the symptom site to perform the needle float therapy. It should be noted that, after the puncture of the floating needle 100 is completed each time, the needle feeder is to reset, that is, the fixing groove 3.3 is pushed backward first, so that the floating needle seat 3 moves backward integrally, when the front end surface of the thick diameter section 3.2 is located at the rear of the limiting plate 6, the limiting plate 6 returns to the first transverse position again under the action of the reset elastic body 4, and then the knob 8 is restored to the locking state.
