Description

The blunt pin of a kind of double-cavity diploporous type
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of blunt pin of double-cavity diploporous type that effectively can detect blood back.
Background technology
Traditional intramuscular injection often adopts sharp pin to inject, and the injection of sharp pin is very high to the requirement of doctor, accidentally just may injure nerve or blood vessel, cause complication, bring more risk.And inject with blunt pin, the injury to face nerve can be avoided.
When using traditional blunt pin to inject, owing to not knowing that the part of syringe needle is positioned at intramuscular or Ink vessel transfusing, for the position of clear and definite syringe needle, often need outwards to pull out the piston rod in needle tubing, when along with piston rod outwards movement, and when having blood to enter in needle tubing, illustrate that the part of syringe needle has been inserted in Ink vessel transfusing, need to extract to reselect injection site, the pain of patient will certainly be increased like this.Meanwhile, when outwards stirring piston rod, blood is filled with syringe needle tube, and this part blood can not be injected into intramuscular again, but directly discards and can cause the pollution of injection areas, there is certain potential safety hazard to other people health.
Utility model content
In order to overcome the deficiency of art methods; the purpose of this utility model is to provide a kind of double-cavity diploporous type blunt pin, can not only realize bluntly being directed to available protecting that is neural and blood vessel, effectively can also detect whether blood back; decrease the pain of patient, and reduce potential safety hazard.
For achieving the above object, this utility model employing technical scheme is:
The blunt pin of a kind of double-cavity diploporous type, comprises needle body, obtuse syringe needle, can realize the protection to neural and blood vessel, enter the wound that tissue can reach minimum by obtuse syringe needle.
Described needle body inside is provided with two-chamber, and described two-chamber is respectively needle body one chamber and needle body two chamber.
Be provided with the pin hole one being communicated with needle body one chamber at needle body outer wall near obtuse syringe needle place, between needle body outer wall pin hole one and obtuse syringe needle, be provided with the pin hole two being communicated with needle body two chamber.
Further, described needle body one chamber is blood back test chamber, and described needle body two chamber is liquid medicine flow chamber.
Further, described needle body one chamber and needle body two chamber are tubular conduit.
Further, the equal ovalize of described tubular conduit cross section, by the lumen body of ellipse can make a time pin upon bending still in holding tube space unimpeded, enhance the liquid communication in lumen.
Further, described two equal ovalizes of pin hole, for coordinating the ellipsoidal structure of two-chamber.
Further, described needle body cross section is circular.
This utility model is the blunt pin of a kind of double-cavity diploporous type, adopts the beneficial effect of the technical program:
By the blunt pin of two-chamber of the present utility model, the protection to neural and blood vessel effectively can be realized; Whether intravasation is inner can to facilitate succinct detection syringe needle; Can effectively solve due to after needle body bending, on the impact of liquid medicine flow; Easy and simple to handle; Decrease the pain of patient, and reduce potential safety hazard.

Wherein, 1 is needle body, and 2 is obtuse syringe needles, and 3 is needle body one chambeies, and 4 is needle body two chambeies, and 5 is pin holes one, and 6 is pin holes two, and 7 is blood vessels, and 8 is muscle.
Detailed description of the invention
In order to make the object of utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model is further elaborated.
In the present embodiment, as shown in Figure 1, the blunt pin of a kind of double-cavity diploporous type, comprises needle body 1, obtuse syringe needle 2, can realize the protection to neural and blood vessel, enter the wound that tissue can reach minimum by obtuse syringe needle 2, and wherein said needle body 1 cross section is circular.
Described needle body 1 inside is provided with two-chamber, and described two-chamber is respectively needle body one chamber 3 and needle body two chamber 4.
Be provided with the pin hole 1 being communicated with needle body one chamber 3 near obtuse syringe needle 2 place at needle body 1 outer wall, the pin hole 26 being communicated with needle body two chamber 4 is provided with between needle body 1 outer wall pin hole 1 and obtuse syringe needle 2, to use in two-chamber a chamber can detect a pin whether intravasation 6, if enter, there is blood back, otherwise otherwise, use another chamber injectable medicinal liquid in two-chamber.
In another embodiment, needle body one chamber 3 is blood back test chamber, and described needle body two chamber 4 is liquid medicine flow chamber.
In another embodiment, needle body one chamber 3 and needle body two chamber 4 are tubular conduit as shown in Figure 2, the equal ovalize of described tubular conduit cross section, by the lumen body of ellipse can make a time pin upon bending still in holding tube space unimpeded, enhance the liquid communication in lumen.
Described two pin holes 5 are ovalize all, for coordinating the ellipsoidal structure of two-chamber.
The operation principle of the blunt pin of double-cavity diploporous type of the present utility model is as follows:
After entering muscle 8 with the blunt pin of double-cavity diploporous type, as shown in Figure 3, if in pin hole 1 intravasation 7 on obtuse syringe needle 2, then blood is by pin hole 1 rearward injection needle place inflow along needle body one chamber 3, can detect and whether blood back phenomenon occurs; Blood back occurs just can not to liquid medicine injection in muscle 8, if two-chamber is all without the generation of blood back phenomenon, and can by needle body two chamber 4 to muscle 8 internal injection medicinal liquid.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
