Abstract

The invention relates to a drainage kit consisting of a drainage tube and a negative pressure bottle. When the drainage kit is used, a hollow three-edged needle with a lateral hole pierces the skin from the inside of the skin and guides the drainage tube out of the skin, then the three-edged needle pierces into the negative pressure bottle from a rubber sealing cover of the negative pressure bottle, and the negative pressure in the bottle is conducted into a subcutaneous cavity through the lateral hole of the three-edged needle, a drainage tube cavity and a lateral hole on the intradermal section of the drainage tube so as to establish a negative-pressure closed drainage loop between the subcutaneous part and the negative pressure bottle. During use, a common injector can be used for extracting the air to recover the negative pressure of the negative pressure bottle; and a bottom interface of the negative pressure bottle can also be connected with a universal negative-pressure drainage device to carry out continuous high negative-pressure drainage.

Description

Wieldy drainage kit

The present invention is a kind of drain medical apparatus and instruments, and is especially easy to use, the supporting use drain medical apparatus and instruments little to skin injury.

At present, in the known drainage way, mainly with sharp knife at the skin puncture, the clamp drainage tube passes skin then, skin is caused than macrolesion, and leave over than clear scar.In addition, also there is inconvenience in drainage tube with being connected of negtive-pressure implement.

In order to overcome the deficiency of present drain medical product, the invention provides a kind of drainage kit, pass skin by integrated rhizoma sparganic syringe needle puncture and guiding drainage tube, then thrust in the negative pressure bottle of rubber seal, between subcutaneous and negative pressure bottle, set up the airtight drain of negative pressure loop simply rapidly, and skin is only left over very little micropore vestige.

The technical solution adopted for the present invention to solve the technical problems is: a kind of hollow plastic pipe of diameter 3-10mm different size, and a terminal evenly distributed aperture wherein, the latter end of the other end is through after the cure process, and caliber reduces 1-2mm.The end of sclerosis section is settled the hollow rhizoma sparganic syringe needle of band side opening.The negative pressure bottle that a rigid plastics that provides simultaneously and rubber are prepared from, the interface that is sealed by rubber cap is left at the bottle end, and the bottle inherence keeps the partial vacuum negative pressure state when dispatching from the factory, and bottleneck seals with serum cap.During use, the sclerosis section of clamping plastic tube, the rhizoma sparganic syringe needle outwards stung out until the sclerosis section major part of drainage tube from the field of operation Intradermal expose outside the skin, subsequently, the sclerosis section that grips drainage tube outside skin goes out skin with the most of tractive of plastics drainage tube, and will be with side opening drainage tube one end to keep somewhere in subcutaneous tract low level.After cut closure, the sclerosis section of clamping plastic tube, with the band side opening the rhizoma sparganic syringe needle and the sclerosis section thrust in the negative pressure bottle from the rubber closure of negative pressure bottle fast, in the bottle negative pressure rapidly the side opening of the side opening by hollow rhizoma sparganic syringe needle, drainage tube chamber, drainage tube Intradermal section conduct in the subcutaneous tract, thereby between subcutaneous and negative pressure bottle, set up the airtight drain of negative pressure loop.In the drain process, if find that negative pressure descends in the negative pressure bottle, available ordinary syringe is thrust the bottleneck serum cap, and the pump drainage air recovers negative pressure; If the negative pressure drainage amount is more or need the high negative pressure constant drainage, rubber cap at the bottom of then can taking out bottle, a bottle end interface connects general negative pressure drainage device continuous negative pressure drainage.

The invention has the beneficial effects as follows that drain is simply rapid, skin is only left over very little micropore vestige.Hollow and short and small rhizoma sparganic syringe needle only need to consume very a spot of stainless steel during fabrication, and drainage tube and negative pressure bottle are made by the nontoxic non-stimulated medical plastic and the rubber of cheapness.Be convenient to create on a large scale disposable product.

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1,2,3, be the drainage kit structural representation

Fig. 4,5 is drainage kit implementation step and principle schematic.

The connecting tube of 2.4 bottles of chambeies of 1.5 tube chambers, 1.6 side opening 2 negative pressure bottles, 2.1 bottle 2.2 bottlenecks, 2.3 interfaces, 2.5 serum caps, 2.6 interfaces, 2.7 rubber caps, 3 syringes, 4 general negative pressure drainage devices is responsible in 1.4 drains of 1 drainage tube, 1.1 rhizoma sparganic syringe needles, 1.2 side openings, 1.3 sclerosis sections among the figure

In Fig. 1, drainage kit is made up of drainage tube (1) and negative pressure bottle (2) two parts.

In Fig. 1,2, drainage tube (1) comprises rhizoma sparganic syringe needle (1.1), drainage tube sclerosis section (1.3) and the drain person in charge (1.4) three parts, wherein by rhizoma sparganic syringe needle (1.1) hollow of metal preparation and be with side opening (1.2), the sclerosis section (1.3) of plastics drainage tube (1) is through after the cure process, caliber is responsible for (1.4) than drain and is dwindled, and (1.4) terminal side opening (1.6) UNICOM mutually of arranging is responsible in the side opening (1.2) on the rhizoma sparganic syringe needle (1.1), tube chamber (1.5) and drain.

In Fig. 1,3, negative pressure bottle (2) is made of with rubber cap (2.7) three parts plastic bottle body (2.1), serum cap (2.5).Interface (2.6) sealed attachment of the bottleneck (2.2) of bottle (2.1) and serum cap (2.5), the interface (2.6) of bottle (2.1) bottom is by rubber cap (2.7) capping.Negative pressure bottle (2) bottle chamber (2.4) keeps the partial vacuum negative pressure state when dispatching from the factory.

Fig. 1,4,5 illustrated embodiments, when using drainage kit (1) (2), clamping drainage tube (1) sclerosis section (1.3), rhizoma sparganic syringe needle (1.1) outwards stung out until sclerosis section (1.3) major part of drainage tube (1) from the field of operation Intradermal expose outside the skin, subsequently, the sclerosis section (1.3) that grips drainage tube outside skin goes out skin with the drain person in charge (1.4) big tractive, keeps somewhere in subcutaneous tract low level and will be with side opening (1.6) drain to be responsible for (1.4).After cut closure, clamping drainage tube (1) sclerosis section (1.3), rhizoma sparganic syringe needle (1.1) and sclerosis section (1.3) are thrust in the negative pressure bottle chamber (2.4) from the serum cap (2.5) of negative pressure bottle fast, negative pressure in the negative pressure bottle chamber (2.4) side opening (1.6) of the side opening (1.2) by rhizoma sparganic syringe needle (1.1), drainage tube chamber (1.5), the drain person in charge (1.4) Intradermal section rapidly conducts in the subcutaneous tract, thereby sets up the airtight drain of negative pressure loop between subcutaneous and negative pressure bottle (2).In the drain process, descend if find the interior negative pressure in negative pressure bottle chamber (2.4), ordinary syringe (3) can be thrust bottleneck serum cap (2.5), the interior air in pump drainage negative pressure bottle chamber (2.4) recovers negative pressure; If the negative pressure drainage amount is more or need the high negative pressure constant drainage, then can take out rubber cap (2.7) at the bottom of the negative pressure bottle, interface at the bottom of the negative pressure bottle (2.6) connects general negative pressure drainage device continuous negative pressure drainage.
