Abstract
The utility model relates to the technical field of medical apparatuses and instruments, and particularly to an anesthesia needle. The anesthesia needle comprises a needle body, a needle handle arranged at the rear end of the needle body, and a needle head arranged at the front end of the needle body, wherein the needle body is equipped with a locating arm; the locating arm and the needle body are distributed as a cross shape; at least two corresponding needles holes are formed on the needle head; and the needle body, the needle head and the needle handle are an integrated structure. By using the locating arm with the crossed structure, the anesthesia needle is convenient for controlling puncture depth during puncture, and can puncture more accurately and relieve pain of the patient; the anesthesia needle employs a multi-needle hole type design, so that injected medicine can be dispersed through a plurality of paths and absorbed rapidly, thus reliving pain of the patient and achieving excellent anesthetic effect; the anesthesia needle is reasonable in structural design and simple in structure.
Description
Technical field
This utility model relates to technical field of medical, especially a kind of anesthetic needle.
Background technology
At present, the anesthetic needle that uses clinically is difficult to the control paracentesis depth, the needle tubing smooth surface when anaesthetizing to patient; Need firmly hold, cause rocking of needle body easily and increase misery to patient, in addition, existing syringe needle all is the single hole syringe needle; When the injecting anesthetic medicine, medicine flows out in the aperture of anesthetic needle syringe needle, owing to be that single hole flows out, its drug distribution is inhomogeneous; Drug diffusion is slow, causes patient to absorb the drug slowly, and anaesthetic effect is undesirable.
Summary of the invention
This utility model technical issues that need to address are: in order to overcome the problem that exists in above-mentioned, and safety when a kind of liquid medicine injection is provided, simple to operate and be convenient to control a kind of anesthetic needle of paracentesis depth.
This utility model solves the technical scheme that its technical problem adopted: a kind of anesthetic needle; Comprise needle body and the syringe needle that is arranged on the needle handle of needle rear end and is arranged on the needle body front end; Described needle body is provided with registration arm; Registration arm and needle body are " ten " font and distribute, and offer at least two corresponding and orthogonal pin holes of axially bored line on the described syringe needle, and needle body, syringe needle and needle handle are monolithic constructions.
In order to be convenient to observe the length of puncture, described needle body outer surface is provided with scale area.
More even in order when injecting, medicine to be disperseed, and can let the patient absorb more quickly, preferably offer 4 corresponding and orthogonal pin holes of axially bored line on the described syringe needle.
In order to make the injection more even distribution, described pin hole shape is circular or oval.
The beneficial effect of this utility model is: described a kind of anesthetic needle, adopt with needle body to be the registration arm that " ten " font structure distributes, and can be convenient to when puncture, can control the degree of depth of puncture, make puncture more accurate, reduce patient's misery; Adopt the design of spininess cellular type, can be when injectable drug, multichannel is disperseed in patient's body apace, and medicine more promptly is absorbed, palliate the agonizing sufferings and effect that anaesthetic effect is good thereby reach, this reasonable in design, simple in structure.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the overall structure sketch map of the described a kind of anesthetic needle of this utility model.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, needle body, 11, registration arm, 2, needle handle, 3, syringe needle, 31, pin hole.
The specific embodiment
Combine accompanying drawing that this utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of this utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
A kind of anesthetic needle as shown in Figure 1; Mainly be to be used for anesthetic syringe, comprise needle body 1 and be fixed on the needle handle 2 of needle body 1 rear end and be the syringe needle 3 that is arranged on needle body 1 front end of monolithic construction that needle body 1 is provided with registration arm 11 with needle body 1; Registration arm 11 is " ten " font with needle body 1 and distributes; Offer four ellipses or circular pin hole 31 on the syringe needle 3, corresponding and axially bored line is vertical each other between pin hole 31 and the pin hole 31, injection can flow out from four pin holes 31 simultaneously.In addition, on the outer surface of needle body 1, be provided with scale area, can clearly see that needle body inserts the intravital degree of depth of people.
The described a kind of anesthetic needle of this utility model; When anaesthetizing injection; Only need the needle handle 2 of this anesthetic needle be stuck in the top of needle tubing, with the place that syringe needle 3 insertions need be anaesthetized, medical personnel can observe the degree of depth that needle body 1 inserts inside of human body according to the scale area on the needle body 1.After needle body 1 inserts certain degree of depth, can be blocked by " ten " font registration arm 11 on the needle body 1, avoided that needle body 1 insertion is too dark, thereby and caused the fracture of needle body 1 to let patient cause suffering.After syringe needle 3 got into the skin endosexine, anesthesia liquid flowed out from four pin holes 31 on the syringe needle 3 equably, and medicine is absorbed by the body fast, reached best anaesthetic effect, had improved medical personnel's work efficiency.
With above-mentioned desirable embodiment according to this utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the description, must confirm its technical scope according to the claim scope.
