Abstract
The invention provides an adsorption-prevention left heart drainage tube, which is formed by sequentially connecting a tube head part, a tube body part and a drainage part with different diameters. A communicated drainage passage is arranged inside the adsorption-prevention left heart drainage tube, a movable ventilation plug is arranged on the side wall of the tube head part, a ventilation hole passage is formed inside the ventilation plug, the bottom of the ventilation plug is provided with a spring supporting the ventilation plug for blocking a side hole, when the spring is in a free state, one opening end of the ventilation passage is blocked by the side wall of the tube head part, and when the spring is compressed, the ventilation passage communicates the drainage passage with the outside. The adsorption-prevention left heart drainage tube has the advantages that the drainage part is set into the round table-shaped structure with the larger end part diameter, and in addition, circular arc-shaped bulges are distributed on the surface of the outer wall, so that the occurrence of the adsorption phenomenon of the drainage part and the left ventricle (heart chamber) wall due to negative pressure can be avoided to the maximum degree, meanwhile, the ventilation plug with the ventilation hole passage is arranged on the tube head part, so that when the adsorption occurs, the ventilation plug is pressed down, an external air flow enters the drainage passage through the ventilation hole passage, and the adsorption phenomenon is eliminated.
Description
Technical field
The present invention relates to medical diagnosis on disease and treatment field medical apparatus and instruments used, a kind of anti-absorption left heart drainage-tube specifically.
Background technology
At present, in cardiac operation, most widely used left heart drainage-tube is when carrying out left heart vacuum suction, inadequate drainage is caused because the reasons such as position easily cause drainage tube to adsorb left atrium (room) wall, thus make surgical field of view unintelligible and repeatedly adjust drainage tube, cause operating time relatively to extend, add potential operation risk.
Summary of the invention
Easily being adsorbed onto for solving left heart drainage-tube of the prior art the problem that left atrium (room) wall causes inadequate drainage when carrying out left heart negative-pressure adsorption, the invention provides a kind of anti-absorption left heart drainage-tube.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of anti-absorption left heart drainage-tube, the tube head do not waited by diameter, tube body and conduction part are connected in sequence, and the diameter of tube head is greater than the diameter of tube body, the diameter of tube body is greater than the diameter of conduction part, at tube head, tube body and conduction part inside are provided with through drainage channel, the diameter of drainage channel in tube body is greater than its diameter in conduction part, described conduction part is truncated cone-shaped structure, its diameter reduces from free end gradually to tube body link, around the outer wall of conduction part being distributed with the conduction hole passed through for blood and the arc-shaped projection be made up of flexible material, be tiltedly installed with in one end that conduction part is connected with tube body connect domatic, and drainage channel also has the domatic of inclination herein, the sidewall of described tube head is provided with the side opening be communicated with drainage channel, moveable breather plug is provided with in this side opening, breather plug inside is provided with vent cap, two openings of vent cap all and ft connection, the bottom of described breather plug is provided with the spring supporting its blocking side opening, and when spring is in free state, an opening of vent cap is blocked by the sidewall of tube head, during Compress Spring, vent cap is by drainage channel and ft connection.
The described drainage channel being arranged in conduction part is provided with and this section of drainage channel is separated into two-part dividing plate, described dividing plate is fixed on the inwall of drainage channel, its one end shrinks in the free end of conduction part, the other end extends in the drainage channel of tube body, and the plane that dividing plate is formed is vertical with breather plug.
The diameter of described drainage channel in tube head is greater than its diameter in tube body.
Beneficial effect: the present invention is by being arranged to the large round table-like structure of end diameter by conduction part, and outer wall surface distribution arc-shaped projection, thus prevent because negative pressure causes the appearance of conduction part and left ventricle (room) wall adsorption phenomena to greatest extent, simultaneously, by being provided with the breather plug of vent cap on tube head, make, when there is absorption, to press breather plug, outer gas stream is entered in drainage channel by vent cap, thus eliminates adsorption phenomena.

Detailed description of the invention
As shown in the figure, a kind of anti-absorption left heart drainage-tube, the tube head 1 do not waited by diameter, tube body 2 and conduction part 3 are connected in sequence, and the diameter of tube head 1 is greater than the diameter of tube body 2, the diameter of tube body 2 is greater than the diameter of conduction part 3, at tube head 1, tube body 2 and conduction part 3 inside are provided with through drainage channel 5, the diameter of drainage channel 5 in tube body 2 is greater than its diameter in conduction part 3, described conduction part 3 is truncated cone-shaped structure, its diameter reduces from free end gradually to tube body 2 link, outer wall around conduction part 3 is distributed with the conduction hole 302 passed through for blood and the arc-shaped projection 301 be made up of flexible material, be tiltedly installed with in one end that conduction part 3 is connected with tube body 2 and connect domatic 201, and drainage channel 5 also has the domatic of inclination herein, the sidewall of described tube head 1 is provided with the side opening be communicated with drainage channel 5, moveable breather plug 4 is provided with in this side opening, breather plug 4 inside is provided with vent cap 401, two openings of vent cap 401 all and ft connection, the bottom of described breather plug 4 is provided with the spring 402 supporting its blocking side opening, and when spring 402 is in free state, an opening of vent cap 401 is blocked by the sidewall of tube head 1, during Compress Spring, vent cap 401 is by drainage channel 5 and ft connection.
Be more than basic embodiment of the present invention, can do on above basis and further improve:
As, the described drainage channel 5 being arranged in conduction part 3 is provided with and this section of drainage channel is separated into two-part dividing plate 6, stating dividing plate 6 is fixed on the inwall of drainage channel, its one end shrinks in the free end of conduction part 3, the other end extends in the drainage channel of tube body 2, and the plane that dividing plate 6 is formed is vertical with breather plug 4, the drainage channel of conduction part is divided into two parts by dividing plate 6, after entering air-flow by vent cap 401, uniform stream can be diverted to both sides like this, thus make conduction part 3 be more prone to depart from from adsorbed state;
And for example, the diameter of described drainage channel 5 in tube head 1 is greater than its diameter in tube body 2, because the diameter of drainage channel 5 in tube body 2 is greater than its diameter in conduction part 3, such drainage channel 5 constitutes the three stage structure that diameter does not wait, and the section diameter that blood has just flowed into is minimum, not only be convenient to entering of air-flow, and absorption can be prevented to a certain extent.
