Abstract

The utility model relates to a one-off chest celiac puncturing guide-flow device, which belongs to a medical treatment apparatus to take the media from the body. The structure of the device is that: a puncturing needle with an absorbing hole and a guide-flow tube is open on the side wall; a flow control valve is arranged on the guide-flow tube; a guide-flow bag with a discharge valve is arranged in the rear of the guide-flow tube; a well-illuminated flow observing kettle is positioned between the flow control valve and the guide-flow bag. The puncturing guide-flow device relies on the principle of siphon smartly to induce the accumulated liquid in the chest celiac puncturing into the guide-flow bag; the device can save the labor, besides, the infection ratio is much less. If the absorbing mode is trouble, the device can also be connected to the negative pressure guide-flow device in order to be convenient for the accumulated to discharge; the device is simple in the structure, convenient in the absorbing mode; the device is convenient to be operated with accurate measuring. The device can decrease the surgery pain for the patient and satisfy the requirement for the clinic cure.

Description

Disposable splanchnocoel puncturing drainer

Technical field

This utility model relates to a kind of disposable splanchnocoel puncturing drainer, belongs to the medical equipment that takes out medium in the body.

Background technology

Thoracicoabdominal puncture be clinical in commonly used diagnosis, treatment means, be commonly used to get rid of hydrops in the splanchnocoel or gas and to breast abdomen perfusion solution.If the utensil defectiveness or the misoperation of puncture usefulness will be brought misery to the patient, even cause malpractice.The disposable splanchnocoel puncturing drainer of public use is many in the prior art is made of puncture needle and drainage tube, use syringe outwards to extract medium after during operation puncture needle being thrust splanchnocoel, need two people's operations, extract repeatedly, not only require great effort, and easily cause infection, it is inaccurate to extract amount of liquid, increased the weight of patient's misery, disease treatment has been caused adverse effect.

Summary of the invention

The purpose of this utility model be for provide a kind of simple to operate, extract disposable splanchnocoel puncturing drainer convenient, accurate measurement, to meet clinical needs.

The technical scheme that this utility model is taked is such: disposable splanchnocoel puncturing drainer, comprise puncture needle and drainage tube in the structure, be characterized in that flow control valve is arranged on drainage tube, drainage bag arranged, flow velocity is housed between flow control valve and drainage bag observes kettle at the drainage tube afterbody.

Above-mentioned disposable splanchnocoel puncturing drainer has imbibing hole on the sidewall of puncture needle.

Above-mentioned disposable splanchnocoel puncturing drainer is provided with bleeder valve in the drainage bag bottom.

The technique effect that this utility model is obtained is: this puncturing drainer is used siphon principle and splanchnocoel pressure differential cleverly, makes puncture back pleural effusions and ascites flow into drainage bag, and is not only laborsaving, and infection chance is few, accurate measurement; If the difficulty of extraction can also connect depression drainage device, in order to drawing of hydrops; Its simple in structure, easy to use, easy operating.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A portion enlarged drawing of Fig. 1.

Fig. 3 is the B portion enlarged drawing of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is further described.

The specific embodiment of the utility model that provides referring to Fig. 1, disposable splanchnocoel puncturing drainer, comprise puncture needle 1 in the structure, drainage tube is made up of

drainage tube

2,5,6,8 more pieces, and flow control valve 3 is housed on drainage tube 2, and its structure is identical with flow speed control valve arrangement on the common medical Transfusion device, movable pulley moves towards the puncture needle direction, flow velocity is accelerated, and the flow velocity that slides in the other direction reduces, and can realize flow speed control.At drainage tube 8 afterbodys drainage bag 9 is installed, drainage bag 9 upper ends are useful on the suspender belt of suspension, bag is marked with graduation mark 11, be used to show the liquid level in the drainage bag, the drainage bag of present embodiment adopts commercially available finished product, be by the Asia that East China, Chinese Yangzhou medical apparatus and instruments Industrial Co., Ltd. produces reach board, specification is the disposable use drainage bag of 1000ml, drainage bag 9 bottoms have bleeder valve 10.Drainage tube 5 adopts the mode that is connected of pegging graft with drainage tube 6, and combination is installed during with handled easily.Flow velocity is housed between drainage tube 6 and drainage tube 8 observes kettle 7, flow velocity is observed kettle 7 usefulness plastic materials and is made ampuliform or tubular, upper and lower sealing, and upper/lower terminal and drainage tube 6 and drainage tube 8 are connected, and observe transparent being easy to of kettle and observe.See Fig. 2, have two imbibing holes 12 on the sidewall of puncture needle 1, be used for auxiliary imbitition.See Fig. 3, the release valve 10 of drainage bag 9 bottoms comprises tubular valve body 13, the top of tubular valve body 13 is fixed in the drainage bag and with drainage bag and communicates, the outside, its underpart is threaded and is set with valve gap 15, valve gap 15 and tubular valve body 13 threaded engagement, inside bottom at valve gap 15 has the tubulose spool (shutoff) 16 that cooperates with valve body inner bore, there is the retaining of protrusion in the outside, tubular valve body 13 bottoms along 17, valve gap 15 upper inner have the snap ring 14 of protrusion, can prevent that valve gap 15 from turning excessively to deviate from from tubular valve body 13 lower ends downwards.Turn valve gap 15 downwards, tubulose spool (shutoff) 16 of valve gap 15 inside bottom withdrawed from from tubular valve body 13, the liquid in the drainage bag just can flow out in the pipe of tubular valve body 13; On the contrary, upwards turn valve gap 15, the tubulose spool (shutoff) 16 that valve gap 15 drives its inside bottom enters in the pipe of tubular valve body 13 and with its shutoff, and the liquid in the drainage bag can not flow out from tubular valve body 13.

This utility model uses very simple, can hold the puncture needle that contains flow control valve during puncture earlier and puncture, and after the success parts such as each joint drainage tube is linked together by diagram, opens flow control valve again and can operate.

This utility model can assemble with existing utensil such as puncture needle, transfusion device and drainage bag etc. when making.
