Description
Technical field
This utility model relates to a kind of sample applicator for upper skin injection, belongs to medical instruments field.
Background technology
Sample applicator is a kind of common medical instruments, and as far back as the 15th century, Italian Ka Di Nellie just proposes the principle of sample applicator, mainly in order to liquid medicine injection or drawing liquid.Sample applicator is made up of the foraminate syringe of front end band and the piston core bar that matches.Sample applicator is used for that a small amount of liquid is injected into other place or from those local extractions out, when core bar is extracted, liquid or gas suck from syringe front end aperture, in the time that core bar pushes, liquid or gas are extruded.Be called injection by this process of sample applicator and syringe needle extraction or injecting gas or liquid.Along with the continuous progress aspect understanding in drug conveying, general injection for curing divides two kinds, and one is subcutaneous injection, exactly injection needle is inserted in muscle medicine is sent into muscular tissue; Another kind is upper skin injection, is exactly drug injection is arrived to skin subcutaneous area, and this just needs sample applicator to have certain accurate orientation with respect to patient skin.But all degree of depth of uncontrollable injection needle insertion skin of present sample applicator, in upper skin injection, need doctor to control syringe needle insertion depth with sensation, accuracy is not high, and in injection process, need seeing at any time that the scale of needle tubing controls the dosage of injection, therefore, these are all urgent problems.
Summary of the invention
The purpose of this utility model is to provide a kind of sample applicator for upper skin injection.
Problem to be solved in the utility model is the problem that the uncontrollable injection needle of existing sample applicator inserts the defect of the degree of depth of skin, uncontrollable injected dose.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
This utility model is for the sample applicator of upper skin injection, comprise syringe needle, snap collar, syringe, piston rod, batcher, limiter, outer sleeve, inner sleeve, buckle and self-locking block, described syringe needle is arranged on syringe, and syringe needle is provided with snap collar, and syringe outer wall is provided with scale numerical value; Piston rod head is elastomeric material, and batcher is contained on piston rod, and batcher can move on piston rod, and piston rod is provided with scale numerical value; Limiter is made up of outer sleeve and inner sleeve two parts, and both are threaded connection, and inner sleeve inwall is provided with buckle, and buckle is the raised points of inner sleeve inwall, and inner sleeve outer wall is provided with scale numerical value, and limiter is coordinated and is contained on syringe needle by buckle and snap collar; Self-locking block is housed on batcher, and self-locking block can move in batcher, and self-locking block is squeezed and can shrinks, batcher be provided with self-locking block one facing to piston rod head.
The utility model has the advantages that: the degree of depth that can control accurately syringe needle and insert skin by being arranged on limiter on syringe needle, the length that rotary sleeve cylinder can change syringe needle and stretches out limiter, and by accurately command range of the scale numerical value on inner sleeve outer wall; Can control the dosage of injection by batcher, therefore in injection process, watch without the moment scale numerical value that syringe goes out attentively, there is feature simple in structure, easy to use.

In figure: 1, syringe needle 2, snap collar 3, syringe 4, piston rod 5, batcher 6, limiter 7, outer sleeve 8, inner sleeve 9, buckle 10, self-locking block.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
This utility model is for the sample applicator of upper skin injection, comprise syringe needle 1, snap collar 2, syringe 3, piston rod 4, batcher 5, limiter 6, outer sleeve 7, inner sleeve 8, buckle 9 and self-locking block 10, described syringe needle 1 is arranged on syringe 3, syringe needle 1 is provided with snap collar 2, and syringe 3 outer walls are provided with scale numerical value; Piston rod 4 heads are elastomeric material, batcher 5 is contained on piston rod 4, and batcher 5 can move on piston rod 4, and piston rod 4 is provided with scale numerical value, piston rod 4 Rubber ends insert in syringe 3, promote and pull piston rod 4 can make piston rod 4 in the interior motion of syringe 3; Limiter 6 is made up of outer sleeve 7 and inner sleeve 8 two parts, both are threaded connection, while turning clockwise outer sleeve 7, the overall length of outer sleeve 7 and inner sleeve 8 shortens, and while being rotated counterclockwise outer sleeve 7, the overall length of outer sleeve 7 and inner sleeve 8 increases, inner sleeve 8 inwalls are provided with buckle 9, buckle 9 is the raised points of inner sleeve 8 inwalls, and inner sleeve 8 outer walls are provided with scale numerical value, and limiter 6 is coordinated and is contained on syringe needle 1 by buckle 9 and snap collar 2; Self-locking block 10 is housed on batcher 5, self-locking block 10 can be in the interior movement of batcher 5, self-locking block 10 is squeezed and can shrinks, batcher 5 be provided with self-locking block 10 one facing to piston rod 4 heads, in the time that piston rod 4 moves forward, self-locking block 10 on batcher 5 touches the end face of syringe 3 and is squeezed, thereby batcher 5 frictional force are increased, and makes piston rod 4 stop moving forward.
This utility model using method: first syringe needle 1 is contained on syringe 3, piston rod 4 is packed in syringe 3, medicine is sucked in syringe 3, then by the air row light in syringe 3, the position of the dosage adjustment quantitative device 5 of injection as required, can regulate by the scale numerical value on piston rod 4; Limiter 6 is contained on syringe needle 1, and rotary sleeve cylinder 7 makes syringe needle 1 and outer sleeve 7 end face, then according to the injection depth outer sleeve 7 that turns clockwise, until rotate to inner sleeve 8 assigned scale; At this moment can carry out epithelium injection for curing with this sample applicator, in injection process, can control accurately injection depth and injected dose.
