Abstract
The utility model relates to a disposable puncture and drainage device for thoracic cavities, which comprises a puncture needle and a three-way switch, wherein, a drainage conduit which is connected with an outlet of the tree-way switch is connected in series with an elastic rubber bag and a regulating switch. The utility model has the advantages of simple and reasonable structure, convenient operation and utility. The utility model can avoid the cross infection, and have certain clinical application value.
Description
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of disposable thoracic drainage and thoracentesis device.
Hydrothorax is called for short hydrothorax, and the hydrothorax tapping is a Medical Technology sex work, and it is widely used among the clinical treatment as a kind of important diagnostic and Therapeutic Method.Hydrothorax mostly is transudate, and most of being oozed out by inflammation after infecting causes, the hydrothorax that moderate is above, and the patient occurs uncomfortable in chest or dyspnea, often needs to do the improvement that the hydrothorax tapping is beneficial to disease.At present, the way of hydrothorax tapping is the method for continuing to use clinically for many years always, promptly thrusts the thoracic cavity with thoracentesis needle from the thoracic wall of position that hydrops is arranged, again and again hydrothorax is extracted out with syringe then.The disadvantage of this method is that hydrothorax is spattered outward and easily caused nosocomial infection and apparatus to use the cross infection that causes repeatedly, and operates cumbersome.For a change this state, people have done some transformations to this.It is ZL97210996X that China's utility patent communique has been announced a kind of patent No. on August 19th, 1998, publication number is CN2287965Y, name is called the drainage device of " disposable airtight puncturing drainer ", this drainage device is to connect a three-way cock behind puncture needle, three-way cock be connected a disposable syringe with the piercing needle horizontal level, become 90 ° to be connected disposable drainage bag in the three-way cock bottom with piercing needle.By switch syringe needle is communicated successively respectively with syringe and drainage bag during use, finish the puncture drainage operation.The shortcoming of this drainage device is that parts contain disposable aspiration needle, and volume is bigger, does not also very coordinate on the structure, and manufacturing cost is also higher.
The purpose of this utility model is to provide a kind of disposable thoracic drainage and thoracentesis device, so that the design of drainage device is more reasonable, structure is simpler.
For achieving the above object, the technical solution of the utility model is to have adopted a kind of disposable thoracic drainage and thoracentesis device, comprises puncture needle and three-way cock, is connected with elastic force leather bag and by-pass cock on the drainage catheter that connects in the outlet of three-way cock.
Not end at drainage catheter can connect a drainage bag.
Because this utility model is behind polyphone elastic force leather bag and by-pass cock on the drainage catheter that connects in the outlet of three-way cock, just saved the aspirator that disposable syringe constitutes, the elastic force leather bag has the dual-use function of suction and drainage channel concurrently, advantages of simple more on the structure, more succinctly coordinate on the whole, smoothly more convenient in the use.This simple and practical, cheap apparatus is more suitable for promoting the use of in medical system as disposable utensil.
Explanation and the explanation this utility model done up below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, puncture needle 1 is connected on the A suitable for reading of three-way cock 4 by the medical plastic pipe, be connected with standby suction tube 3 on the side mouth B of three-way cock 4, be connected with medical plastic drainage catheter 7 on the end opening C of three-way cock 4, on plastics drainage catheter 7, be equipped with elastic force leather bag 5 and roller by-pass cock 6, on the lower port of drainage catheter 7, be connected with drainage bag 8.In order to keep puncture needle 1 health, dressing on syringe needle has sheath 2.In the present embodiment, puncture needle 1 is selected the 12-14 pin for use, long 7.5cm.Elastic force leather bag volume selects 30-50ml.Drainage catheter 7 is long for about 120cm.
This drainage device can follow these steps to use:
A, selected site of puncture, sterilization and anesthesia are identical with traditional method;
B, regulate three-way cock 4 a mouthful A, a mouthful C are communicated, treat that puncture needle enters when subcutaneous, pinch flat elastic force leather bag 5, close by-pass cock 6, keep negative pressure.
C, advance puncture needle, when arriving the thoracic cavity, hydrothorax can flow out under the suction of elastic force leather bag 5, after treating that the elastic force leather bag restores to the original state, open by-pass cock 6, at this moment, hydrothorax constantly flows in the drainage bag 8 automatically by siphon principle, and also the suction of reliable elastic force leather bag aspirates repeatedly;
Behind d, the end of operation, extract the puncture needle pressure dressing.
Supplementary notes: when auto-pumping is had any problem, the scalable three-way cock, a mouthful A, a mouthful B are communicated, by standby suction tube 3 suctions, regulate three-way cock 4 with syringe then, a mouthful B, a mouthful C are communicated, hydrothorax in the syringe is released, flow in the drainage bag 8 by plastics drainage catheter 7, needn't take away syringe, so repeatable operation can be finished.
