Abstract

The utility model relates to an anaesthesia syringe, particularly a syringe for performing local anaesthesia on muscle tissue of a cervix internal opening before operations of artificial abortion. The utility model is composed of a syringe needle head, a retainer and a casing. The utility model is characterized in that a needle tube of the needle head is comparatively long, can be extended into the casing through a circular hole at the bottom of the retainer sheathed at the rear end of the casing, and can enable the needle tip to extend out the casing from the front end of the casing and penetrate into muscle tissue of the cervix internal opening; the anesthesia physic liquid is injected into the muscle tissue of the cervix internal opening by pushing the piston of the syringe. Using the anaesthesia syringe can achieve favorable anesthesia effect, ease pain of the patients who are operated on, and reduce incidence of artificial abortion syndromes.

Description

Anesthessia syringe

This utility model relates to a kind of anesthetic syringe, particularly relates to implementing the preceding syringe that woman uterus is carried out local anesthesia of artificial abortion.

In order to implement the basic state policy of family planning, artificial abortion operation has become a kind of birth-control measures that generally adopt.In 60～seventies, do not adopt anesthesia measure and analgesic when implementing this operation, most of operation receiveing person's pain are unbearably, many operation receiveing persons are more arranged, and the mechanical stimulus that negative pressure causes during because of the suction palace is shunk the uterus strongly, vagus nerve stimulation is excited and the artificial abortion syndrome occurs, as pale complexion, be in a cold sweat bradycardia, arrhythmia, cardiac arrest etc. are twitched in severe patient even faintness.Over past ten years, domestic many department of obstetrics and gynecology medical personnel are alleviating operation receiveing person's misery, are reducing and to do a lot aspect the artificial abortion syndrome sickness rate.Soak into 1% tetracaine, 0.5～1ml as Chongqing No.3 People's Hospital's obstetrics and gynecology department aseptic cotton carrier in 1984 and insert and reach the cervix uteri internal orifice in the cervical canal and took out in 1～2 minute, and then the operation that artificially induces abortion.The Chinese patent " disposable uterine cavity syringe " (patent No. 92208398.3) that Tao Yong obtains provides a kind of syringe to uterine cavity surface injection analgesic drug product, it comprises syringe, inject bar, the front end that it is characterized in that syringe is curved, have some injection orifices on the tube wall around its centre and syringe are forward, its rear end tube wall is thick slightly, and adapted has the bar of injecting of syringe now.This syringe can only implement artificial abortion operation forward direction operation receiveing person uterine cavity inner surface injection analgesic (because of medicinal liquid be flow to by injection orifice intrauterine), can not be to uterine cavity or cervix uteri intramuscular injection anaesthetic, can only make the uterine cavity surface obtain infiltration type anesthesia, thereby the effect of anesthesia is not good enough, can not remove fully the operation receiveing person when performing the operation pain and the generation of artificial abortion syndrome.

The purpose of this utility model is that it can make operation receiveing person's pain alleviate greatly for artificial abortion operation provides a kind of anesthetic syringe that can directly obtain good anaesthetic effect to cervix uteri internal orifice muscular tissue injecting anesthetic medicine (as lignocaine).

This utility model is like this design, and it is made up of syringe 10, syringe needle 1, its feature it also have sleeve pipe 5, stop 2, wherein: A, stop 2 is cylindrical, a center, the end is provided with circular hole; Stop 2 is enclosed within the rear end of sleeve pipe 5 and can advances to the front end of sleeve pipe 5 along the outer wall of sleeve pipe 5; The front end of B, sleeve pipe 5 is closed circular arc, slick and sly crooked apart from the beginning of its front end 29～31mm place; The angle α of slick and sly crooked back leading portion centrage and back segment centrage is 5 °; The center hole that C, the syringe needle 1 that links together with syringe 10 pass stop 2 bottoms puts in the endoporus of sleeve pipe 5, and the endoporus of sleeve pipe 5 is provided with the outlet 8 of needle point 9 on the shell of its leading portion, and outlet 8 communicates with the endoporus slyness of sleeve pipe 5; Needle tubing 3 length of D, syringe needle 1 should make its needle point 9 can stretch out needle point outlet 8 outer 10～15mm.The centrage angle β of the endoporus leading portion centrage of sleeve pipe 5 and needle point outlet 8 is 20 °.Be provided with handle 7 in the rear end of sleeve pipe 5, in the beginning of 6～8mm place, distance rear end, the outer wall of sleeve pipe 5 is provided with the long scale of 10～15mm.Desire is during to the operator administration of anaesthetic, then stop 2 can be set to the rear end of sleeve pipe 5, the nozzle of stop 2 is to the position of good sleeve pipe 5 high scales " 0 ", to have the syringe 10 of anaesthetizing medicinal liquid again and load onto syringe needle 1, the circular hole that syringe needle 1 passes stop 2 puts in the sleeve pipe 5 and reaches needle points always and exports 8 places (needle point not extended needle points outlet 89 this moments), sleeve pipe 5 is slowly put in operation receiveing person's intravaginal behind the cervix uteri internal orifice, promote stop 2, then stop 2 can be with syringe 10, syringe needle 1 advances to the cervix uteri internal orifice, needle point 9 stretches out needle point outlet 8 and lunges cervix uteri internal orifice muscular tissue, thrusting the degree of depth also can be learnt from the scale on the sleeve pipe 5 by stop 2 controls, but should not surpass 10～15mm the deeplyest, then just can pushing syringe 10 inject piston, to anaesthetize medicinal liquid and slowly annotate in the neck internal orifice muscular tissue of being put in prison, inject dose 5～10mml.Can undergo surgery in 5 minutes behind the injection anesthetics.

Advantage of the present utility model: 1, adopt this anesthetic syringe the anesthesia medicinal liquid can be injected directly in the cervix uteri internal orifice muscular tissue, improved anaesthetic effect.2, simple in structure, easy to operate.3, alleviate operation receiveing person's pain, reduced the sickness rate of artificial abortion syndrome effectively.
