In the present embodiment, the fixing rod 201 is a tube structure with an opening at one end (the upper end shown in the figure), and the adjusting rod 202 is inserted into the fixing rod 201 along the axis direction and can move up and down in the fixing rod 201. The adjustment lever 202 is provided with an angle scale 204. The guiding device for vaccination can be used for accurately controlling the needle inserting angle of upper arm deltoid muscle subcutaneous injection, the height of the adjusting rod 202 extending out of the fixing rod 201 is correspondingly adjusted through the adjusting locking mechanism 4, the angle scale 204 on the adjusting rod 202 is obtained through height conversion, and the required needle inserting angle can be directly realized through height adjustment. The mark post 3 is arranged at the contact position of the fixed belt 1 and the adjustable guide frame 2 and is vertical to the axes of the fixed belt 1 and the adjustable guide frame 2, and the mark post 3 can rotate around a fixed point. When the mark post 3 rotates to the vertical position, the injector is supported on the bracket 203 at the top of the adjustable guide frame 2, and the needle inserting angle of the injector can be determined through two point positions of the bracket 203 and the mark post 3.
In a first embodiment, refer to fig. 1 to 3. The adjusting and locking mechanism 4 in the present scheme specifically includes a rack 401 and an adjusting knob 402, the adjusting knob 402 has a head 402a and a rod 402b, wherein the head 402a is located at one end of the rod 402b, the rod 402b is provided with a gear 402c, and the other end thereof is vacant; a window 201a used for the up-and-down movement of the adjusting knob 402 is arranged on the fixing rod 201, a mounting hole 202a used for penetrating the rod part 402b of the adjusting knob is arranged on the adjusting rod 202, the rod part 402b with a gear 402c penetrates through the window 201a of the fixing rod, the vacant end of the rod part 402b extends into the mounting hole 202a, and the head part 402a of the adjusting knob is positioned outside the window 201a of the fixing rod; the rack 401 is fixed to the fixing rod 201 such that the rack 401 is engaged with the gear 402c of the adjusting knob. Wherein the rod portion 402b of the adjusting knob is cylindrical. A rack mounting opening is formed in the fixed rod, and the rack 401 is inserted into the mounting opening. Positioning pin holes 401a are formed in each tooth groove of the rack 401, a pin shaft 403 can be in plug-in fit with any positioning pin hole 401a, and the pin shaft 403 serves as a clamping device to prevent the gear 402c and the rack 401 from moving relatively after being in place.
In the adjusting and locking mechanism 4, the gear 402c is fixed on the rod 402b, and the free end of the rod 402b is freely inserted into the mounting hole 202a, so as to ensure that the rod 402b of the adjusting knob 402 can rotate in the mounting hole 202a of the adjusting lever 202. The head 402a of the adjusting knob 402 is rotated to engage the gear 402c on the rod 402b with the rack 401, so as to drive the adjusting rod 202 to move up and down in the fixing rod 201, and after the adjusting rod 202 is in place, the gear 402c can be locked by the pin 403 to prevent rolling. The adjusting and locking mechanism is accurate in positioning and convenient to operate, all parts can be made of plastic materials, the disassembly and assembly are convenient, and the manufacturing cost is low.
Example two, refer to fig. 4. Of course, the adjusting and locking mechanism has a simple form, which adopts the pressing bolt 6, at this time, the fixing rod 201 is provided with a threaded through hole, and the pressing end of the pressing bolt 6 extends into the fixing rod through the threaded through hole, so that the pressing end face presses the adjusting rod 202. The mode has simple structure and composition and more convenient operation, but the accuracy is relatively poor due to the inclined condition of the adjusting rod 202 in the adjusting process, and the mode is used as a replacement scheme.
The specific use of the inoculation guide in the form of a rack and pinion is illustrated.
The height of the adjustable guide frame 2 is adjusted according to different angle requirements, namely, the adjusting knob 402 is rotated, and the adjusting rod 202 moves up and down through the matching of the gear 402c and the rack 401; after the angle scale 204 on the adjusting rod 202 is adjusted to a desired angle, the pin 403 is inserted into the positioning pin hole 401a, so as to prevent the position of the adjusting rod 202 from being changed due to external extrusion or unintentional rotation of the adjustable guide frame 2. The fixing band 1 is fixed on the upper arm of a patient, the marker post 3 is rotated to a vertical position, the end head part of the marker post 3 is aligned with the puncture point, and the injector punctures towards the puncture point by taking the bracket 203 as a supporting point. After the injection operation is finished, the mark post 3 can be rotated to be overlapped with the fixing band 1, and the influence on subsequent disinfection and puncture is avoided.
In the concrete application, fixed band 1 can adopt thread gluing formula fixed band, also can use papa circle formula, and plasticity is formed in patient's upper arm after the fixed band location, plays the effect of fixed adjustable guide frame 2, does not influence the operator and operates simultaneously, convenient fixed operation. The angle range of the adjustable guide frame 2 is set to be 30-45 degrees according to the commonly used puncture angle range in puncture. In the specific adjustment of the angle, the device is used for calculating the injection angle of the injector according to the length of the mark post 3 and the height of the adjustable guide frame 2, so that the distance between scales is different when the scales are marked. The injection angle is calculated according to the length of the marker post 3 and the height of the adjustable guide frame 2 and then marked on the adjusting rod 202, so that the angle can be accurately adjusted in the operation process, and the angle scale to be adjusted is parallel to the upper end face of the fixed rod 1. In order to facilitate the scale observation, an observation port is arranged below the upper end surface of the fixed rod 1.
