Abstract
The utility model relates to the technology field of medical instruments, and particularly relates to an anesthetic syringe, comprising a syringe cylinder, a syringe needle at the top of the syringe cylinder, and a piston rod used for pushing syringe liquid, the syringe cylinder is formed by an inner syringe cylinder and an outer syringe cylinder, cooling fluid is disposed between the inner syringe cylinder and the outer syringe cylinder, the piston rod and the inner wall of the inner syringe cylinder are in a sliding connection, the top of the syringe needle is at least provided with two circular holes. The anesthetic syringe is provided with cooling liquid between the inner syringe cylinder and the outer syringe cylinder, making an anesthetic take a better effect, thereby preventing destruction upon the anesthetic; the syringe needle is provided with a plurality of circular holes, quickening absorption of medicament and uniform distribution of medicament during anesthesia, thereby improving operating efficiency, the anesthetic syringe is advantaged by simple design structure and convenient use.
Description
Technical field
This utility model relates to technical field of medical, especially be a kind of anesthetic syringe.
Background technology
At present, Anesthesia Department of hospital is when carrying out clinical anesthesia, and the required apparatus of using is a syringe; Because the injection tube of the present syringe that uses is single layer structure, need be placed on dark place and need be in frozen state such as some special anesthetis, cause narcotic anesthesia performance less than optimum efficiency easily if preserve perhaps improper use; In addition, the top of the syringe needle of some syringe only offers an aperture, when carrying out the injecting anesthetic medicine; Anaesthetic flows out in the aperture of syringe needle; Injectable drug like this causes the skewness of anaesthetic easily, and patient absorbs the drug slowly; Reduced medical personnel's work efficiency, brought bigger misery to patient.
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, provide a kind of simple in structure, drug distribution evenly and can make the anesthetic syringe of anesthetis performance optimum efficiency.
This utility model solves the technical scheme that its technical problem adopted: a kind of anesthetic syringe; Comprise injection tube and the piston rod that is arranged on the vertical syringe needle of injection tube and is used to promote injection; Described injection tube is made up of interior injection tube and outer injection tube; Be provided with liquid coolant between injection tube and the outer injection tube in described, piston rod and interior injection tube inwall are slidingly connected, and the top of said syringe needle is provided with two circular holes at least.
For in when anesthesia, can make that medicine is evenly distributed, administration rapidly and patient absorb soon, described circular hole quantity is four.
For can be in use, prevent that syringe needle is loosening and cause a hidden trouble that described injection tube is to be threaded with syringe needle.
For can be when using syringe, can effectively avoid the syringe phenomenon of trying to shirk responsibility, the outer wall of said outer injection tube is provided with anti-skidding stricture of vagina.
The beneficial effect of this utility model is: described anesthetic syringe, between inside and outside injection tube, be provided with liquid coolant, and can make anesthetis bring into play better effect, thereby avoid destruction the anesthetis drug effect; On syringe needle, offer a plurality of circular holes, can be when anaesthetizing, accelerate the patient to the absorption of medicine and make the medicine can uniform distribution, thereby improved medical personnel's work efficiency; This project organization is simple, and is easy to use.
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 said a kind of anesthetic syringe of this utility model.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, injection tube, 11, interior injection tube, 12, outer injection tube, 2, syringe needle, 21, circular hole, 3, piston rod.
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 syringe as shown in Figure 1; Comprise injection tube 1, the top of injection tube 1 syringe needle 2 that has been threaded, the top of syringe needle 2 is provided with four circular holes 21; Injection tube 1 is made up of with outer injection tube 12 interior injection tube 11; The piston of piston rod 3 front ends interior injection tube 11 inwalls closely cooperate and piston rod 3 and interior injection tube 11 inwalls between for being slidingly connected, interior injection tube 11 and outside be provided with liquid coolant between the injection tube 12, can make anesthetis performance optimum efficiency.In addition, the outer wall of injection tube 12 is provided with anti-skidding stricture of vagina outside.
The anesthetic syringe method for using of this utility model is: the top that at first syringe needle 2 is screwed into injection tube 1 through screw thread rotation; For those special anesthetis; Those anesthetis that need under frozen state, use particularly; Interior injection tube 11 and outside inject liquid coolant between the injection tube 12 and make its sealing state that forms vacuum, interior injection tube 11 in, add injection (anesthetis) then, the internal injection tube 11 interior injection (anesthetis) of the liquid coolant between interior injection tube 11 and the outer injection tube 12 cool off; Can make anesthetis under the state of cooling, bring into play best property of medicine effect, thereby inject.
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.
