Abstract
The invention discloses a kind of fixed puncture angle and the intracutaneous injection needle assemblies of depth, including intradermal needle, and the fixed bracket of intradermal needle, wherein, intradermal needle can connect syringe, and it is used for skin penetrating, the fixed bracket of intradermal needle is used to control the puncture angle and paracentesis depth of intradermal needle.The beneficial effect that the present invention obtains is: simplifying the operating process of the intracutaneous injection during clinic diagnosis, precisely fixed puncture angle and depth, eliminate the feeling of pain in intradermal injection.
Description
Technical field
The present invention relates to the intracutaneous injection needle assemblies applied when a kind of clinical intracutaneous injection, especially one can fix puncture angle
The intracutaneous injection needle assemblies of degree and depth, belong to medical instruments field.
Background technique
Intracutaneous injection is the method being injected in a small amount of drug or biological products between epidermis and corium, and skin test belongs to skin
One kind of interior injection is the common operation during clinic diagnosis, and also referred to as intradermal sensitivity tests is needed in patient using antibiosis
Before plain and certain special medications, it is required to carry out the skin test of relative medicine, it can when excluding and avoid infusion relative medicine
The allergic reaction that can be generated.
Trial drug is injected to intradermal by requirement when intracutaneous injection, and endo-endothelial layer punctures through shallow between epidermis and corium
And the too deep effect that will affect intracutaneous injection.
Since intracutaneous injection depth is in endo-endothelial layer, this is in the distribution of impassivity and blood vessel, therefore, in this regional injection
It tends not to cause pain and bleeding, and below endo-endothelial layer is skin corium and hypodermic layer, the nerve ending and pain temperature at the position
Feel that receptor distribution is more, if deep-controlled undesirable in intracutaneous injection, pin puncture subject at this region is past by puncturing
Toward feeling more pain.
The control of paracentesis depth determines the effect of intracutaneous injection in intradermal injection, and the control of paracentesis depth is often
It is more difficult, long-term clinic training is needed, even if experienced medical staff, control depth is also difficult in puncture injection,
Then it often leading to subject and there is more strong feeling of pain during intracutaneous injection, subject is often more frightened,
Therefore, it is difficult to control to solve the paracentesis depth in puncture process, and reduces the pain even being eliminated in intradermal injection
Pain has been invented the intracutaneous injection needle assemblies of a kind of fixed puncture angle and depth, can have been worn with certain puncture angle
Thorn, and paracentesis depth is fixed on endo-endothelial layer, intradermal needle syringe needle is made of 3 to 9 micro needle heads, to eliminate skin test process
In feeling of pain.

Have limit, to fix the paracentesis depth of intradermal needle, it is preferable that the intracutaneous injection pin puncture storehouse tilt angle be 15 to
90 degree.
When the intradermal needle of described device is fixed in intracutaneous injection pin puncture storehouse, micro needle head tip protrudes from skin
The line of interior injection needle support bracket fastened front foot and the rear foot, it is preferable that prominent length is 1 to 10 millimeter.
Use process of the described device in skin test, with micro needle head quantity for 3 pieces, intracutaneous injection pin puncture storehouse inclination angle
Degree is illustrated for a kind of 45 degree of preferred embodiment.
State before the use of described device, when being in the state, the intradermal needle is located at the intracutaneous injection
In the support bracket fastened intradermal needle storage silo of needle.
The use state of described device, firstly, intradermal needle is taken out out of intradermal needle storage silo, after put
Enter in intracutaneous injection pin puncture storehouse, upper and lower limits are equipped in intracutaneous injection pin puncture storehouse, it is deep with the puncture for fixing intradermal needle
Syringe equipped with skin test drug after intradermal needle is fixed, is connected to the circular open at intradermal needle needle body rear portion by degree,
Hereafter, the support bracket fastened front foot of intradermal needle and the rear foot are affixed on subject's arm skin, hand syringes and to subject
Skin direction is exerted oneself, so that 3 pieces of micro needle heads of intradermal needle are pierced into subjects skin's epidermis, and is entered endo-endothelial layer, is injected
Liquid flowing channel needle body section and 3 liquid communications of the emitter to endo-endothelial layer test injection drug, in drug percutaneous in injection needle
Road syringe needle section enters endo-endothelial layer, after injection, removes intracutaneous injection needle assemblies, operation terminates.
In this application, if be not particularly described, the positional relationship of various components is position based on the figure
Relationship is set, used device, instrument, component, size and other conditions etc. are all well-known in the art or ability
Field technique personnel combine the prior art may be implemented according to the description of application.
