Abstract

The utility model discloses a pericardiocentesis drainage apparatus, which comprises a needle core and an outer casing, wherein the side wall of the tail end of the outer casing is connected with a drainage tube; the drainage tube is connected with a liquid injection tube and a collecting tube through a tee joint respectively; a liquid injection plug is arranged at the top end of the liquid injection tube; the collecting tube is provided with a drip tube and a flow switch, and is connected with a collecting bottle at a tail end; the body of the collecting bottle is marked with graduation marks; and the corner of the bottom end of the collecting bottle is provided with a liquid drainage switch. The pericardiocentesis drainage apparatus is reasonable in structure, and is easy and convenient to operate; and in a use process, the needle head can be prevented from hurting cardiac muscles, and the infection rate can be lowered effectively during injection of medicaments and lavage of heart-sacs.

Description

The pericardiocentesis drainage device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of pericardiocentesis drainage device.

Background technology

At present, the method that adopts puncture to extract to pericardial effusion patient's treatment clinically more, employed pericardiocentesis drainage device is mainly by syringe needle; Drainage tube and syringe are formed, and this type pericardiocentesis drainage device exists many drawbacks in the use, at first; The piercing needle of existing pericardiocentesis drainage device is sharper; After penetrating pericardium, beat from what heart did not stop, needle point is easy to injury of myocardium; When using existing pericardiocentesis drainage device lavation pericardium or in pericardium during injectable drug; Must earlier drainage tube be pulled out; Inject after plugging syringe, pull out syringe behind the end of operation, plug drainage tube once more to external drainage; So very easily infect during repeatable operation, bring misery to the patient.

The utility model content

For overcoming above-mentioned technical problem, this utility model provides a kind of reasonable in design, reduces the pericardiocentesis drainage device of operation easier.

For realizing above-mentioned technical purpose; This utility model is to adopt following technical scheme to realize: a kind of pericardiocentesis drainage device, comprise that an inside is provided with the trocar sheath of nook closing member, and the outer end of trocar sheath is provided with thimble plug; Trocar sheath tail end sidewall is connected with drainage tube; Drainage tube connects liquid injection pipe and collecting pipe respectively through threeway, and the top of liquid injection pipe is equipped with the fluid injection plug, and collecting pipe is provided with dropper, flow switch and connects receiving flask at tail end; Receiving flask indicates graduation mark on one's body, and receiving flask bottom edge is a draining switch.

The beneficial effect of this utility model is: rational in infrastructure, easy and simple to handle, can avoid the needle sting cardiac muscle in the use, and can effectively reduce the infection probability when injectable drug and lavation pericardium.

Accompanying drawing is this utility model structural representation.

Among the figure, 1, trocar sheath, 2, nook closing member, 3, thimble plug, 4, drainage tube, 5, threeway, 6, liquid injection pipe, 7, the fluid injection plug, 8, dropper, 9, flow switch, 10, collecting pipe, 11, receiving flask, 12, graduation mark, 13, draining switch.

The specific embodiment

With reference to accompanying drawing, this utility model comprises a trocar sheath 1, and the inside of trocar sheath 1 is nook closing member 2; The top of trocar sheath 1 is a thimble plug 3, and trocar sheath 1 side connects drainage tube 4, and the threeway 5 on the drainage tube 4 connects liquid injection pipe 6 and collecting pipe 10 respectively; The top of liquid injection pipe 6 is equipped with fluid injection plug 7, is separately installed with dropper 8 on the collecting pipe 10, flow switch 9 and receiving flask 11; Receiving flask 11 is marked with graduation mark 12, and receiving flask 11 bottom edges are draining switch 13.When this utility model used, the doctor can puncture under ultrasonic surveillance, when nook closing member 2 penetrates into the pericardium internal layer; Nook closing member 2 is slowly retreated, and trocar sheath 1 is pushed pericardial cavity, thimble plug 3 is pushed in the trocar sheath 1 after withdrawing from nook closing member 2; Both can carry out drawing liquid, trocar sheath 1 is whole mouthful an of flush end, so can heart not stabbed; When needs in pericardium when injectable drug and lavation pericardium, directly open fluid injection plug 7 injectable drug or other liquid in pericardium after flow switch 9 cuts out and get final product, close fluid injection plug 7 after finishing; Open number of times can effectively reduce the infection probability when this process had reduced fluid injection.

Claims

1. a pericardiocentesis drainage device comprises that an inside is provided with the trocar sheath of nook closing member, and the outer end of trocar sheath is provided with thimble plug; It is characterized in that: trocar sheath tail end sidewall is connected with drainage tube; Drainage tube connects liquid injection pipe and collecting pipe respectively through threeway, and the top of liquid injection pipe is equipped with the fluid injection plug, and collecting pipe is provided with dropper, flow switch and connects receiving flask at tail end; Receiving flask indicates graduation mark on one's body, and receiving flask bottom edge is a draining switch.
