Description

Disposable ascites pleural fluid drainage device

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of apparatus that is used for the drain ascites pleural fluid.

In the prior art, be used for clinically on the apparatus of drain ascites pleural fluid by one section sebific duct, the puncture needle that is installed in sebific duct one end termination portion constitutes.Syringe is connected with sebific duct during the suction ascites pleural fluid.When clinical use, carry out routine disinfection at the point of puncture position earlier, the hole of the aseptic hole-towel after the sterilization is aimed at point of puncture cover the point of puncture position, carry out puncture drainage after the local anesthesia.In the drain process, device to be injected must be assisted to clamp the sebific duct that connects syringe needle with vascular forceps after taking out the full packages chamber by the assistant, prevent that gas from entering splanchnocoel, take off the liquid of syringe exhaustjet organ pipe intracavity simultaneously, connect syringe more again, unclamp vascular forceps and continue to extract out ascites pleural fluid, need repeatedly the said process suction repeatedly, in aspirating the ascites pleural fluid process repeatedly, easily affect the syringe needle swing, stab luminal organ, if misoperation easily makes gas enter the thoracic cavity and hydropneumothorax occur.In addition, the syringe needle after the use, sebific duct, syringe should in time be sterilized, and need sterilization again to use after 3-7 days but surpass.If sterilization is thorough or surpass use, also easily cause cross infection.

The purpose of this utility model is that syringe needle is stable when disclosing a kind of ascites pleural fluid drain, and not air inlet in the thoracic cavity does not cause cross infection, only needs the disposable ascites pleural fluid drainage device of one man operation.

This utility model is to realize like this.The syringe needle that on the shank of pegging graft on the upper end of drainage tube, has the side conduction hole, for the ease of finishing the back to breast abdomen injectable drug in drain, be serially connected with threeway on the drainage tube, be with one section flexible pipe that connects syringe on the side connector of threeway, the port of flexible pipe is equipped with is convenient to fill in tube sealing mouth and the stopper of extracting.Be enclosed within the control folder of controlling liquid flow velocity on the drainage tube and break-make, the lower end of drainage tube is communicated with liquid-collecting bottle by pegging graft.Liquid-collecting bottle is the long tubular flexible plastic bottle with contraction and the planning function of termination sealing up and down.The upper end of liquid-collecting bottle is inserted with a lower port and breaks away from the bottle end in liquid-collecting bottle, upper port is exposed the feed tube of liquid-collecting bottle, exposed portions serve is the connection-peg of drainage tube, the lower end of liquid-collecting bottle is inserted with the liquid level equilibrium pipe that a upper port is higher than mouth at the bottom of the feed tube at the bottom of the bottle in bottle, at the bottom of the lower port of liquid level equilibrium pipe was exposed bottle, exposed portions serve was for connecting the connection-peg of discharging tube.Feed tube and liquid level equilibrium pipe are plastic tube, constitute overall structure by heat seal and liquid-collecting bottle.There are one and the integrant exhaustor of liquid-collecting bottle in the upper end of liquid-collecting bottle in a side of feed tube, and one-way exhaust valve is housed on the exhaustor.By grafting a discharging tube is installed on the connection-peg that the liquid level equilibrium pipe exposes, is set with the control folder of controlling liquid flow velocity and break-make on the discharging tube.

Instructions for use and effect:

At first close the control folder on drainage tube and the discharging tube before the drain, with hands liquid-collecting bottle is pinched flatly, the gas of liquid-collecting bottle is discharged from one-way exhaust valve, and liquid-collecting bottle is negative pressure state.The site of puncture through sterilization, local anesthesia is laggard punctures, regulating sleeve is contained in the clip on the drainage tube after puncturing successfully, under the liquid-collecting bottle suction function, ascites pleural fluid is inhaled in the liquid-collecting bottle through syringe needle, drainage tube, treat to open when liquid level is higher than on the balance pipe pipe clip that is sleeved on the discharging tube, ascites pleural fluid just constantly enters in the liquid-collecting bottle from drainage tube, constantly discharges from discharging tube again simultaneously.Carry out continuously because of drain, change the disadvantage that syringe gas enters splanchnocoel easily when having avoided with the drain of syringe interruption.When the needs negative pressure drainage, as long as will be sleeved on the control clip closure on drainage tube and the discharging tube, pinching flat liquid-collecting bottle discharges gas, liquid-collecting bottle promptly is in negative pressure state, open the control folder that is sleeved on the drainage tube this moment, liquid just is inhaled in the liquid-collecting bottle, close the control folder that is sleeved on the drainage tube when waiting to reach pressure balance, open the control folder on the discharging tube, hands is pinched liquid-collecting bottle, liquid is just discharged from discharging tube, close the control folder on the discharging tube immediately under the state of not loosing one's grip, unclamp the hands of pinching liquid-collecting bottle, this moment, liquid-collecting bottle was in negative pressure state, open the control folder that is sleeved on the drainage tube, can proceed negative pressure drainage.Close the control folder that is sleeved on the drainage tube after drain finishes, pull out the stopper on the threeway side connector flexible pipe termination, syringe and hose connection injects thoracic cavity or intraperitoneal with medicine.This drainage device only needs one man operation, and syringe needle is stable in the drain process, has stopped careless manipulation and gas enters the disadvantage that the thoracic cavity produces hydropneumothorax, stabs internal organs, has also stopped the chance of use the generation cross infection because of repeating to make simultaneously.

Disposable ascites pleural fluid drainage device is when producing, and its employed disposable syringe, nonwoven hole cloth, sterile gauze and sterilization test tube when doing the ascites pleural fluid drain is encapsulated in the bag, and medical domain is called the puncture bag.It is very suitable for the relatively poor basic hospital of condition.
