Abstract
The utility model discloses an indwelling type drainage device, comprising a puncture needle 1, a drainage tube 3 and a negative pressure device 4. The puncture needle 1 is a trocar with hollow inner, and the lateral wall of the puncture needle 1 is provided with a through slot 2. One end of the drainage tube 3 is inserted in the puncture needle 1, the other end of the drainage tube 3 is connected with the negative pressure device 4, and a cross valve 5 is arranged in the middle of the drainage tube 3. Using the indwelling type drainage device, a patient has light pain, comfort and safety.
Description
Technical field this utility model relates to a kind of medical equipment, the remain-type drainage system that uses in particularly a kind of splanchnocoel operation.
Often need carry out medicine filling processing in drainage from indwelling and the splanchnocoel after the operation of background technology splanchnocoel to splanchnocoel, at present, indwelling drainage tube mainly contains two kinds of methods clinically, a kind of is that local skin cuts perforation, place drainage tube, a kind of puncture needle that is to use, piercing needle is kept somewhere in vivo, external drainage tube.The shortcoming that exists is: first method step complexity, and patient is painful big, and second method patient can not take free position, keeps somewhere syringe needle and easily internal organs is caused damage.
The summary of the invention the purpose of this utility model is to provide a kind of overcome above-mentioned shortcoming, the painful remain-type drainage system little and safe and convenient to use of patient.
This utility model is achieved in that a kind of remain-type drainage system, comprises puncture needle, drainage tube and negative pressure device, and this puncture needle is the trocar of inner hollow, sidewall is offered axial pass trough, drainage tube one end is inserted in puncture needle inside, and the other end connects negative pressure device, and the centre is provided with three-way valve.
Use of the present utility model is: finish puncture with puncture needle earlier, arrest drainage tube then, withdraw from puncture needle, utilize axial pass trough to take off puncture needle, realize the indwelling operation of drainage tube, in this process, three-way valve is in closed condition, swivel tee valve then, drainage tube and negative pressure device are connected, carried out drain, need be in body cavity during administration, the swivel tee valve is realized the administration operation by the three way cock again.As from the foregoing, use this device drainage from indwelling, need not operate on, patient's misery is little, and piercing needle is not retained in the patient body, and patient does not have the position restriction, uses comfortable, safety.
Description of drawings Fig. 1 is this utility model sketch map.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment as shown in the figure, puncture needle 1 front end is a tip-like, inner hollow, sidewall is offered axial pass trough 2, drainage tube 3 one ends are inserted in puncture needle 1 inside, the other end connects negative pressure device 4, the centre is provided with three-way valve 5.Be the convenient length that drainage tube 3 inserts, the mark scale 6 on the drainage tube 3 grasped.Negative pressure device 4 can adopt the automatic negative-pressure capsule, and its crust is the tub that flexible plastic is made, and offers air inlet above, and inside is provided with compression spring, and during use, dead spring is closed air inlet, forms negative pressure in the capsule naturally.Drainage tube 3 adopts flexible plastic or medical grade silicon rubber material.
