Abstract
The utility model provides a venous cannula with an enhanced liner, which is used to establish the cardiopulmonary bypass during cardiac surgeries. The utility model consists of a pipe and a drainage port connected with one end of the pipe; wherein, the pipe is a smoothing and transitional structure with variable diameters, the inside wall of the pipe is provided with an enhanced liner, the cavity of the pipe is smooth and unimpeded; the pipe and the drainage port are made of nontoxic PVC material and the enhanced liner is processed from a stainless steel wire. The venous cannula is anti-extrusion, bent-resistant and flexible; when in use, the utility model can be bent at random the putting position can be adjusted, the bigger-diameter end of the pipe is easy to be connected with a connecting pipe, the transition section is smooth, thereby ensuring the pipe unimpeded; the PVC material has good transparency and are convenient for observing the situation of blood. The venous cannula has the characteristics of simple operation, safe and reliable, and is widely used in cardiopulmonary bypass operation.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, particularly relates to the unobstructed band reinforcing line venous cannulation of using when a kind of department of cardiac surgery is set up cardiopulmonary bypass surgery of anti-extruding, bend resistance, drain.
Background technology
The venous cannulation of setting up the cardiopulmonary bypass surgery clinical practice at present known department of cardiac surgery has two kinds, a kind of is the venous cannulation of not being with reinforcing line, easily produces the discounting phenomenon when this kind intubate is used, and causes blood flow to block, have a strong impact on operation technique, jeopardize patient's life; Another kind is the venous cannulation of band reinforcing line, in the direct perforate of intubate one end as the drain head, the aperture is subjected to the influence of the hardness of body own, wall thickness and intensity etc., drainage flow is little, intubate is isometrical shape, is connected difficulty with extracorporeal circulation system, influence operation quality, increased medical personnel's burden, its material causes the transparency of intubate and suppleness relatively poor.
Summary of the invention
This utility model provides a kind of anti-extruding, bend resistance, the unobstructed band reinforcing line venous cannulation of drain for solving the technical problem that exists in the known technology.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Band reinforcing line venous cannulation is to be made of body and the drain head that is connected in body one end, and the body other end is and seamlessly transits not isometrical shape, is provided with reinforcing line in the tube body wall, and the drain head is the macroporous type of brace rod than the faciola tapering.
This utility model can also adopt following technical measures:
Described body and drain head all adopt nontoxic PVC material, and reinforcing line is processed by stainless steel silk.
Advantage and the good effect that the utlity model has are: the drain header structure is designed to be with the tapering macroporous type, is easy to insert human body, is beneficial to drain, be provided with reinforcing line in the tube body wall, make the anti-extruding of intubate, bend resistance, pliability good, can be arbitrarily crooked during use, adjust putting position, the body larger diameter end is easy to the socket connection pipe, guarantees that the junction spaciousness is unobstructed, and changeover portion is smooth, guarantee that pipeline is unblocked, adopt the PVC material, its transparency is better, is easy to observe blood circumstance.This intubate is easy and simple to handle, safe and reliable, has alleviated medical personnel's burden, can be widely used in the cardiopulmonary bypass surgery.
Description of drawings
Fig. 1 is an overall structure sketch map of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Band reinforcing line venous cannulation is to be made of body 1 and the drain 2 that is adhered to body 1 front end, body 1 other end is for seamlessly transitting not isometrical shape, be provided with the reinforcing line 3 that processes by stainless steel silk in the tube body wall, drain 2 is the macroporous type of brace rod than the faciola tapering, and body and drain head all adopt nontoxic PVC material.
During clinical use, the body cavity intravenouss are inserted in drain 2, the hole of blood on the drain head enters in the body, flows into extracorporeal circulation system through tube cavity.
Claims (2)
1. be with the reinforcing line venous cannulation for one kind, be to constitute by body (1) and the drain head (2) that is connected in body one end, it is characterized in that: body (1) other end is and seamlessly transits not isometrical shape, is provided with reinforcing line (3) in the tube body wall, and drain head (2) is the macroporous type of brace rod than the faciola tapering.
2. band reinforcing line venous cannulation according to claim 1 is characterized in that: body (1) and drain head (2) all adopt nontoxic PVC material, and reinforcing line (3) is processed by stainless steel silk.
