Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a device for preventing blood from splashing during cardiac and large blood vessel surgery. Background Art
[0002] The great blood vessels of the heart usually refer to the main blood vessels that supply blood to the heart, mainly the anterior descending branch and circumflex branch of the left coronary artery, and the right coronary artery. Since the blood pressure inside the great blood vessels of the heart is very high, blood will splash out from the puncture site during heart surgery. If it is not blocked in time by hand, a large amount of splashed blood will cover the surgical field of view, affecting the doctor's surgical vision and endangering the patient's life.
[0003] According to publication number CN215458332U, a device for preventing blood from splashing during cardiac and large vessel surgery is disclosed. When in use, the release paper is pulled out to stick the adhesive layer of the connecting belt to the surgical site. When the needle is embedded in the inner through hole of the sealing component, the needle contacts the sealing plate and pushes the sealing plate downward. At this time, the sealing plate squeezes the spring of the spring hinge on the blocking plate and is compressed. When punching, the positioning component, the sealing component and the sealing plate can block the blood. After the needle is pulled out, the spring hinge pulls the sealing plate back to its original position to seal the inner through hole to prevent blood from splashing after the needle is pulled out. When the operation is completed and the bleeding at the punching site is not stopped, the blood will be stored under the sealing component of the positioning component. Subsequently, due to the effect of blood pressure, the blood will push the sealing component upward, causing the connecting column above the sealing component to move upward and squeeze the press switch of the fixing component, so that the alarm will sound an alarm to remind medical staff and monitor the patient's hemostasis condition.
[0004] The structure of the above alarm device enables monitoring of the patient's hemostasis condition. However, after the patient bleeds, the blood will push the sealing component upward due to the blood pressure. At the same time, the blood is also easy to squeeze the sealing plate and splash out of the connecting belt through the sealing plate, thereby affecting the normal operation of medical staff.

[0011] As a further improvement of the above solution, the inner through hole and the liquid storage cavity have the same shape and size, and the friction surface is composed of a plurality of concave surfaces.
[0012] As a further improvement of the above scheme, the sealing mechanism includes an arc-shaped plate, which is fixedly connected to the inner wall of the mounting plate, a sealing valve body is fixedly connected to the side of the arc-shaped plate away from the mounting plate, a guide plate is fixedly connected to the bottom end of the mounting plate, and a sensor is fixedly connected to the bottom end of the mounting plate.
[0013] Through the above technical solution, the puncture punch is passed through the normally closed seal formed by the sealing valve body. At the same time, the sealing valve body is bent by the arc plate. When the arc plate is bent, the sealing valve body is received in the guide plate.

Since the arc plate is thin and a soft material is used, the deformation degree of the sealing valve body is improved. When the arc plate is bent, the sealing valve body is received in the guide plate. When bleeding occurs, the guide plate can play a certain protective role, so that the sealing valve body is prevented from being stained with blood, thereby increasing the protective effect of the sealing valve body.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0025] Example:
[0026] Please combine Figure 1-4, a blood splash prevention device for cardiac and large blood vessel surgery of this embodiment comprises a main body mechanism 1, a connecting mechanism 2 and a sealing mechanism 3, wherein the connecting mechanism 2 is located at the bottom end of the main body mechanism 1, and the sealing mechanism 3 is located inside the main body mechanism 1;
[0027] The main body mechanism 1 includes a connecting substrate 101, the top of the connecting substrate 101 is fixedly connected to a connecting column 102, the middle of the connecting column 102 is provided with a liquid storage cavity 103, the inner wall of the connecting column 102 is fixedly connected to a mounting plate 104, the top of the mounting plate 104 is fixedly connected to a liquid guide tube 105, the top of the liquid guide tube 105 is fixedly connected to a liquid outlet tube 106, the top of the liquid outlet tube 106 is fixedly connected to a micro high-pressure pump 107, the top of the micro high-pressure pump 107 is fixedly connected to a collecting tube 108, and the top of the connecting substrate 101 is fixedly connected to a friction protrusion 109.
[0028] The connecting substrate 101 is made of silicone material, and there are two liquid guide tubes 105 .
[0029] The connecting mechanism 2 includes an adhesive portion 201, which is fixedly connected to the bottom end of the connecting substrate 101, an inner through hole 202 is opened in the middle of the adhesive portion 201, a friction surface 203 is fixedly connected to the bottom end of the adhesive portion 201, and a release paper 204 is arranged at the bottom end of the adhesive portion 201.
[0030] The inner through hole 202 and the liquid storage cavity 103 have the same shape and size, and the friction surface 203 is composed of a plurality of concave surfaces.
[0031] The sealing mechanism 3 includes an arc plate 301, which is fixedly connected to the inner wall of the mounting plate 104, a sealing flap 302 is fixedly connected to the side of the arc plate 301 away from the mounting plate 104, a guide plate 303 is fixedly connected to the bottom end of the mounting plate 104, and a sensor 304 is fixedly connected to the bottom end of the mounting plate 104.
[0032] There are four arc plates 301 , which are distributed around the mounting plate 104 and combined into a closed ring. The thickness of the sealing petal 302 is greater than that of the arc plate 301 , and the inner diameter of the guide plate 303 is the same as the outer diameter of the arc plate 301 .
[0033] The implementation principle of a blood splash prevention device for cardiac and vascular surgery in the embodiment of the present application is as follows:
[0034] The release paper 204 is torn off from the adhesive part 201, and the connecting substrate 101 and the adhesive part 201 are covered above the cardiac great blood vessel to be punctured, and the connecting column 102 is aligned with the puncture and punching position, and the puncture punch is passed through the normally closed seal formed by the sealing flap 302.
