Description

TECHNICAL FIELD

[0001] The utility model relates to perfusion tube technical field especially relates to a novel coronary perfusion tube. BACKGROUND

[0002] In the field of heart surgery, coronary perfusion tube is the key equipment to ensure that the myocardial protective fluid can be uniformly and continuously perfused into the coronary blood vessels. It is of great significance to maintain the activity of myocardial tissue, reduce damage during surgery and improve the success rate of surgery. With the continuous progress of medical technology, the design of coronary perfusion tube is also constantly optimized.

[0003] The traditional coronary perfusion tube usually adopts a single fixed structure, which is fixed in the coronary blood vessel by a simple mechanical fixing method. During the operation, medical staff will use external equipment to inject myocardial protective fluid into the perfusion tube to protect the myocardial tissue. However, this fixing method often has the risk of perfusion tube falling off and myocardial protective fluid leakage, especially in the case of different patient vessel thickness or complex operation, this risk is particularly prominent.

[0004] Although the inflatable bag or balloon structure in the prior art improves the stability of the coronary perfusion tube to some extent, there are still many defects. For example, the inflation degree of some inflatable bags or balloons cannot be flexibly adjusted according to the individual differences of patients, resulting in that in some cases it is impossible to achieve close fitting of the perfusion tube, thereby affecting the perfusion effect and causing the reduction of practicability. Therefore, we propose a new type of coronary perfusion tube to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a novel coronary perfusion tube, which solves the problem that the inflation degree of some inflatable bags or balloons in the prior art cannot be flexibly adjusted according to the individual differences of patients, resulting in that in some cases it is impossible to achieve close fitting of the perfusion tube, thereby affecting the perfusion effect and causing the reduction of practicability.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] A novel coronary perfusion tube, comprising a flow guide bag, one end of the flow guide bag is communicated with a perfusion tube, the other end of the flow guide bag is communicated with a flow guide pipe, the end of the perfusion tube away from the flow guide bag is communicated with a perfusion head, the perfusion head is made of flexible material soft rubber, and the perfusion head is spherical, a perfusion hole is formed on the perfusion head, and a flow channel communicated with the perfusion hole is arranged inside, an inner end balloon is fixedly connected to the inner wall of the perfusion tube, an inflatable bag is fixedly connected to the outside of the perfusion tube, a water injection assembly connected with the inner end balloon is arranged on one side of the perfusion tube, and an inflation assembly connected with the inflatable bag is arranged on the other side of the perfusion tube.

[0008] Preferably, the inflation assembly comprises an inflation pump arranged on the other side of the perfusion tube, one side of the inflation pump is connected with an inflation tube, one end of the inflation tube away from the inflation pump is connected with one end of the inflation balloon, and the inflation tube, the inflation pump and the inflation balloon are internally connected.

[0009] Preferably, the water injection assembly comprises a syringe arranged on one side of the perfusion tube, one end of the syringe is connected with an input tube, one end of the input tube away from the syringe penetrates the perfusion tube and is connected with the inner end balloon.

[0010] Preferably, the input tube is externally provided with a valve at one end close to the syringe.

[0011] Preferably, the syringe and the inner end balloon are connected through the input tube to form a closed space, and the closed space is filled with liquid, and the liquid in the closed space is physiological saline.

[0012] Preferably, the two ends of the flow guide balloon are fixedly connected with the adjacent ends of the flow guide tube and the perfusion tube, and the adjacent ends of the perfusion tube and the perfusion head are fixedly connected.

[0013] The utility model has the following beneficial effects:

[0014] After the inflation pump is started, the generated gas is efficiently transported to the inflation balloon through the inflation tube, so that the inflation balloon gradually expands and closely adheres to the intima of the coronary artery. This physical pressure mechanism effectively prevents the perfusion tube from falling off and the myocardial protective solution from leaking, providing a stable foundation for continuous perfusion during the operation. The syringe serves as a physiological saline pushing device, allowing medical personnel to accurately control the inflation degree of the inner end balloon according to actual needs. As physiological saline is injected into the inner end balloon, the increase in its volume exerts additional pressure on the perfusion tube, making it adhere more closely to the intima of the coronary artery. This close adhesion not only ensures that the myocardial protective solution can be uniformly and continuously perfused into the coronary artery, but also improves the perfusion effect, providing more adequate protection for the myocardial tissue. Taking into account the individual differences of patients, medical personnel can flexibly adjust the inflation degree of the inner end balloon according to the thickness of the patient's blood vessels, realizing personalized treatment for different patients. Not only does this enhance the practicality and flexibility of the perfusion tube, but also makes the surgical operation more precise and efficient. BRIEF DESCRIPTION OF DRAWINGS

Perfusion head 4 is provided with perfusion hole, and is provided with flow channel communicated with perfusion hole, and inner end balloon 8 is fixedly connected to the inner wall of perfusion pipe 3, and inner end balloon 8 is located in the inside of perfusion pipe 3, and is inflated after being filled with water by water injection assembly, and is tightly attached to the inner wall of coronary artery, and the stability of perfusion pipe 3 is increased, and perfusion liquid is prevented from leaking. Perfusion pipe 3 is fixedly connected with air bag 7 outside, and one side of perfusion pipe 3 is provided with water injection assembly connected with inner end balloon 8, and the other side of perfusion pipe 3 is provided with inflation assembly connected with air bag 7, and air bag 7 is located outside perfusion pipe 3, and is inflated after being inflated by inflation assembly, and further fixes the position of perfusion pipe 3, and at the same time reduces the interference of external factors on perfusion process, and improves the stability of perfusion pipe 3 in coronary artery, and reduces the surgical risk caused by perfusion pipe falling off or displacement.

[0024] Further, the inflation assembly comprises an inflation pump 5 arranged on the other side of the perfusion tube 3, one side of the inflation pump 5 is connected with an inflation pipe 6, one end of the inflation pipe 6 away from the inflation pump 5 is connected with one end of the inflation bag 7, and the inflation pipe 6, the inflation pump 5 and the inflation bag 7 are internally connected. Through the arrangement of the inflation pipe 6, the inflation pump 5 is started to transmit gas to the inflation bag 7 through the inflation pipe 6, so that the inflation bag 7 can be in an inflated state, and the outer wall of the inflated inflation bag 7 will tightly adhere to the intima of the coronary artery under the action of pressure, like the inflated inflation bag 7 is stuck in the coronary artery, thereby preventing the perfusion tube 3 from falling off and the leakage of the perfusion myocardial protective solution, and the smooth outer wall of the inflation bag 7 will not cause damage to the intima of the coronary artery.

[0025] Further, the water injection assembly comprises a syringe 10 arranged on one side of the perfusion tube 3, one end of the syringe 10 is connected with an input pipe 9, one end of the input pipe 9 away from the syringe 10 penetrates the perfusion tube 3 and is connected with the inner end balloon 8. Through the arrangement of the input pipe 9, the personnel operate the syringe 10 to transmit the physiological saline in the syringe 10 to the inner end balloon 8 through the input pipe 9, and when the appropriate amount of saline is injected, the valve 11 is closed to leave the saline in the inner end balloon 8, so that the inner end balloon 8 is inflated and the perfusion tube 3 is inflated to increase the force on the intima of the coronary artery to adhere, so that the myocardial protective solution can be uniformly and continuously perfused into the coronary artery, and to some extent, the problem of different blood vessel thicknesses due to individual differences is solved, avoiding the overflow of the myocardial protective solution during the perfusion process due to the poor adhesion of the perfusion tube 3 and the perfusion head 4 to the coronary artery, and improving the practicability of the perfusion tube 3.

Through the arrangement of the syringe 10, it is convenient for medical staff to operate the syringe 10 to inject saline into the inner end balloon 8 to inflate the perfusion tube 3 to the coronary artery and adhere.

[0029] In summary:

[0030] The inflation pump 5 serves as a power source, which starts to generate gas when it is started. The gas is effectively delivered into the inflation bag 7 through the transmission channel of the inflation tube 6. After receiving the gas, the inflation bag 7 gradually increases in volume until it reaches a predetermined inflation state. The inflated inflation bag 7 tightly adheres to the intima of the coronary artery, preventing the perfusion tube 3 from falling off and the myocardial protective liquid from leaking by using physical pressure; the syringe 10 serves as a physiological saline storage and pushing device, which is operated by medical staff and accurately pushes the physiological saline into the inner end balloon 8 through the connecting channel of the input tube 9. When the inner end balloon 8 receives an appropriate amount of physiological saline, its volume increases, exerting additional pressure on the perfusion tube 3, making it more tightly adhere to the intima of the coronary artery. This tight adhesion ensures that the myocardial protective liquid can be uniformly and continuously perfused into the coronary vessel, improving the perfusion effect. The dual action of the inflation assembly and the water injection assembly makes the position of the perfusion tube 3 in the coronary artery more stable, reducing the risk of falling off. The stable position of the perfusion tube 3 ensures that the myocardial protective liquid can be continuously and uniformly perfused into the coronary vessel, reducing the leakage of the perfusion liquid, so that medical staff can adjust the inflation degree of the inner end balloon 8 according to the thickness of the blood vessels of the patient, thereby adapting to the individual differences of different patients. This adaptability improves the practicability and flexibility of the perfusion tube 3, making the operation safer and more effective.
