Abstract
The utility model relates to a screw type teat jointed injecting device, and the outer side of the teat of a needle pipe is provided with a jointed outer pipe with an inner screw thread. The back end of a transfusion flexible pipe connected with a scalp needle is connected with a jointed inner pipe with an outer screw thread. When the screw type teat jointed injecting device is used, the jointed inner pipe is screwed in the jointed outer pipe to cause the teat to be inserted into the inner hole of the screw type teat jointed injecting device. When the medical liquid is injected, a needle head can not fall off. The screw type teat jointed injecting device has the advantages of convenient use, labor saving and safety.
Description
This utility model belongs to the injector for medical purpose technical field.
Existing its syringe needle of injector for medical purpose is inserting mode with being connected of needle tubing, though it is in most of the cases easy to use, but for the above specification syringe of 20ml when carrying out the intravenous injection medicinal liquid, when particularly injecting 60% cardiografin or 50% hypertonic glucose, pressure increases does not notice that slightly syringe needle will take place to come off, not only cause liquid waste and environmental pollution, the influence treatment is operated, and also can injure staff's eyes sometimes.The staff is when injection liquid for this reason, fixed needle and needle tubing joining place on the other hand, and a hand propelled pintle, thereby operation is inconvenient, wastes time and energy.
The purpose of this utility model provides a kind of syringe needle and is connected reliably the syringe that injection liquid is easy to operate with needle tubing.
The technical solution of the utility model is: it has needle tubing and is contained in the interior pintle of needle tubing, the front end of needle tubing has nipple, the outside of nipple is fixed on the linking outer tube that has female thread of needle tubing front end in addition, be connected in the outer tube by pipe in the linking that is threaded, nipple inserts pipe in this linking hermetically, the pipe outer end connects infusion tube in being connected, and the infusion tube end has scalp acupuncture.
The utility model has the advantages that: be threaded owing to adopt, can not cause syringe needle to come off during injection liquid, cause liquid waste and environmental pollution, easy to operate, safe and reliable, be particularly suitable for the intravenous injection medicinal liquid and use.
Accompanying drawing is a front view of the present utility model, shows its overall structure.
In the embodiment that accompanying drawing provides, needle tubing 1 and pintle 2 are identical with existing product, and its construction features is to have increased a linking outer tube 4 that is fixed in needle tubing 1 front end again in nipple 3 outsides of needle tubing 1 front end, are connected in the outer tube 4 and have female thread.The rear end of the infusion tube 8 that is connected with scalp acupuncture 9 and one is connected interior pipe 5 and is connected, and pipe 5 utilizes its forward external screw thread 6 to be screwed in the linking outer tube 4 in being connected, and nipple 3 closely is plugged on its endoporus.Easy to operate when spinning, the anterior outside of pipe 5 also has handle 7 in being connected.
This product can be disposable syringe, opens the package the syringe needle needle tubing is screwed and can use.
