Abstract
The utility model relates to a left heart suction tube of dual-chambers and variable diameters, which comprises a dual-chambers pipe body. A big chamber inside the pipe body is a drainage chamber and a small chamber is an air pressure adjusting chamber and the two are in homoaxial; the pipe body head is a pliable insert end; the drainage chamber and the air pressure adjusting chamber are communicated with each other near the insert end; at least four drainage holes are arranged on the outer side wall of the drainage chamber; the pipe far from the insert end is designed in olivary shape flat transited of varied diameter; the air pressure adjusting chamber far from the insert end is provided with a pipe joint communicated with an air pressure adjusting chamber small connecting pipe provided with a three-way valve. The utility model has the advantages that during operation, through adjusting the negative pressure inside the small connecting pipe of the three-way valve air pressure control and adjust chamber to avoid the excessive negative pressure inside the suction tube to damage the patient's endocardium and blood and block the drainage hole by the gore, the utility model is suitable for the connection of pipelines of various specifications and can reduce the medical personnel's work, shorten the operation time and release the patient's pain.
Description
Technical field
This utility model belongs to the clinical apparatus of using of medical treatment, particularly relates to a kind of drain of Cardiac Surgery cardiopulmonary bypass surgery, two-chamber reducing left side heart suction catheter to reducing pressure in the heart of being used for.
Background technology
At present, the doctor is clinical to be needed when doing cardiac operation under direct vision routine to set up extracorporeal circulation to carry out the intracardiac surgery operation to guarantee cardiac arrest, and the common employing of extracorporeal circulation pipeline is the left heart suction catheter of single cavity configuration, because the left heart attracts negative pressure unsuitable excessive in cardiac operation under direct vision, but pressure in the suction catheter of single chamber and traffic attraction are difficult to control, so cause damage of patient's endocardium or blood to destroy easily, simultaneously owing to occur the phenomenon that clot also can be gambled the plug conduction hole in the blood; In addition, the pipe joint of the bonding certain size of tail end of single chamber suction catheter has limitation when other pipeline of needs and extracorporeal circulation is connected, so not only bring inconvenience to operation of medical workers, cause operating time to prolong, but also can increase the danger of operation.
Summary of the invention
This utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be convenient to medical personnel's operation and can shorten operating time be used for the drain of Cardiac Surgery cardiopulmonary bypass surgery, to reducing pressure in the heart and can alleviating the two-chamber reducing left side heart suction catheter of left heart preload.
The technical scheme that this utility model is taked for the technical problem that exists in the solution known technology is:
Two-chamber reducing left side heart suction catheter, comprise that internal diameter is provided with the body of two-chamber, it is characterized in that: this body is the two-chamber variable-diameter structure, one of them big chamber, homoaxial two chambeies is a drainage tube in the body, loculus is the air pressure adjustment chamber, the body head is the insertion end that is slick and sly shape, described drainage lumens and air pressure adjustment chamber are being communicated with near the insertion end place, on the lateral wall of body drainage lumens, have four conduction holes that are communicated with drainage lumens at least, away from the design of the body of insertion end be seamlessly transit waney olive-shaped, be provided with an interface tube that is communicated with it in body air pressure adjustment chamber away from the insertion end position, in this interface tube, be connected with the air pressure adjustment chamber connection tubule that its end is fixed with three-way valve.
Advantage and the good effect that the utlity model has are: because body of the present utility model adopts the two-chamber variable-diameter structure, and by the three-way valve on the air pressure adjustment chamber connection tubule, visual concrete condition is regulated three-way valve and is controlled the traffic attraction that the air pressure adjustment chamber connects intratubular negative pressure and then regulates drainage tube in operation, takes place with the phenomenon of avoiding the excessive patient's of causing endocardium damage of negative pressure or blood destruction and clot gambling plug conduction hole; This suction catheter will away from the design of the body of insertion end be seamlessly transit not isometrical olive-shaped, so not only can adapt to the connection of plurality of specifications pipeline, alleviate medical personnel's workload, but also can shorten operating time, reduce the danger of cardiac surgery operation, and alleviated misery for the patient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion amplification profile of Fig. 1:
Fig. 3 is the B portion structure enlarged drawing of Fig. 1;
Fig. 4 is the profile of Fig. 3.
Among the figure: 1-body, 2-air pressure adjustment chamber connect tubule, 3-three-way valve, 4-drainage lumens, 5-air pressure adjustment chamber, 6-conduction hole, 7-insertion end.
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:
See also Fig. 1-Fig. 4, two-chamber reducing left side heart suction catheter, comprise that internal diameter is provided with the body 1 of two-chamber, this body 1 is the two-chamber variable-diameter structure, in interior homoaxial two chambeies of body, one of them big chamber is a drainage lumens 4, loculus is air pressure adjustment chamber 5, the body head is the insertion end 7 that is slick and sly shape, described drainage lumens and air pressure adjustment chamber are being communicated with near insertion end 7 places, have four conduction holes that are communicated with drainage lumens 6 on the lateral wall of body drainage lumens 4, the conduction hole 6 on the described drainage lumens lateral wall is the layout that is staggered.Be away from the design of the body of insertion end and seamlessly transit waney olive-shapedly, the slick tapering of body afterbody can connect the pipeline of plurality of specifications caliber so in use, and it is easy, convenient and practical to peg graft.Be provided with an interface tube that is communicated with it in body air pressure adjustment chamber 5 away from the insertion end position, be connected with the air pressure adjustment chamber connection tubule 2 that its end is fixed with three-way valve 3 in this interface tube, three-way valve 3 connects tubule 2 by the air pressure adjustment chamber and is communicated with body air pressure adjustment chamber 5.
Concrete operations flow process of the present utility model is:
This utility model is applied in the cardiac operation under direct vision, when using, two-chamber reducing left side heart suction catheter is inserted patient's left atrium, other pipeline of body afterbody connector outer circulation.Open three-way valve 3 when inserting in patient's body, air pressure adjustment chamber 5 is open state, is beneficial in the body gas and discharges, and visual concrete condition is regulated three-way valve 3 in the use, controls negative pressure in the suction catheter drainage lumens 4 by regulating three-way valve.When the patient's recovering beat of heart of operation back, close three-way valve 3,5 sealings of air pressure adjustment chamber can prevent that like this gas from entering blood damage patient brain.
