Problems solved by technology

[0003] During heart surgery, in order to obtain a clearer surgical field, a vacuum suction device for heart surgery is usually used. However, in the existing vacuum suction device for heart surgery, the liquid collection bottle is easy to fall, causing the liquid inside the liquid collection bottle to flow out and cause pollution. In the operating room, for patients with infectious diseases, once the waste liquid generated during the operation contaminates the operating room, it is easy to cause the spread of iatrogenic viruses. The patient’s diseased tissue is often scratched due to the suction of the waste fluid generated during the operation, resulting in more trauma to the patient during heart surgery. At the same time, the noise of the vacuum pump is too loud when it is working, which seriously affects the medical staff. Perform surgery for which a surgical vacuum suction device is proposed

Embodiment 1

[0058] The following is attached Figure 1-10 The present invention is described in further detail.

[0059] A surgical vacuum suction device, such as Figure 1-10 As shown, it includes a bottom support part 1, a liquid collection device 2 and a negative pressure generating device 3. The liquid collection device 2 is detachably installed on the upper part of the bottom support part 1, and the liquid collection device 2 and the negative pressure The pressure generating device is connected in 3 phases;

[0060] The bottom support part 1 includes a cylindrical base 32, the upper part of the cylindrical base 32 is provided with a cylindrical groove 33, and the bottom of the cylindrical base 32 is installed at an equal angle with the center point of the bottom as the center of the circle. a rubber foot 34;

[0061] The liquid collection device 2 includes a liquid collection bottle 9 detachably installed inside the cylindrical groove 33, the upper end of the liquid collection bot...

Embodiment 2

[0073] The difference from Example 1 is that the surface of the shell 35 is also provided with an anti-corrosion layer, and the anti-corrosion layer is prepared by the following method:

[0074] Take the following raw materials and weigh them by weight: 35 parts of acrylic resin, 12 parts of calcium carbonate, 15 parts of p-toluenesulfonic acid powder, 6 parts of mica powder, 18 parts of phenolic resin, 3 parts of glycerin, 8 parts of alcohol ester twelve, trichloro 1 part of ferric chloride solution and 40 parts of water;

[0075] S1, add the weighed glycerin, ferric chloride solution, alcohol ester twelve and water into the mixer and stir for 20min, the stirring speed is 600r / min, and the mixed solution is obtained;

[0076] S2, adding acrylic resin, calcium carbonate, p-toluenesulfonic acid powder, mica powder and phenolic resin into a ball mill for fine grinding until the particle diameter is not greater than 40um to obtain a mixed powder material;

[0077] S3. Add the mi...

Embodiment 3

[0082] The difference from Example 2 is the preparation of the anti-corrosion layer, and its specific preparation method is as follows:

[0083] Take the following raw materials and weigh them by weight: 40 parts of acrylic resin, 16 parts of calcium carbonate, 18 parts of p-toluenesulfonic acid powder, 8 parts of mica powder, 22 parts of phenolic resin, 4 parts of glycerin, 10 parts of alcohol ester twelve, trichloro 2 parts of ferric chloride solution and 50 parts of water;

[0084] S1, add the weighed glycerin, ferric chloride solution, alcohol ester twelve and water into the mixer and stir for 25min, the stirring speed is 700r / min, and the mixed solution is obtained;

[0085] S2, adding acrylic resin, calcium carbonate, p-toluenesulfonic acid powder, mica powder and phenolic resin into a ball mill for fine grinding until the particle diameter is not greater than 40um to obtain a mixed powder material;

[0086] S3. Add the mixed powder material prepared in step S2 to the m...

Abstract

The invention discloses a surgical vacuum aspiration device which comprises a bottom support part, a liquid collection device and a negative pressure generation device, wherein the liquid collection device is detachably mounted at the upper part of the bottom support part; and the liquid collection device is communicated with the negative pressure generation device. According to the surgical vacuum aspiration device, tipping of a liquid collection bottle can be effectively avoided; outflow of liquid in the liquid collection bottle can be avoided; contamination of an operating room by the liquid in the liquid collection bottle can be effectively avoided, so that iatrogenic viral transmission is avoided; damage of a vacuum pump due to entry of the liquid can be effectively avoided, so that aservice life of the device is guaranteed; a clear operation field environment is provided for medical care personnel by vacuum aspiration of waste liquid generated in a cardiac surgery of a patient,so that successful performance of the surgery is guaranteed; scratches of a pathological tissue of the patient can be avoided; traumas generated in the cardiac surgery of the patient can be effectively reduced; and the influence of too large noise during operation of the vacuum pump on the surgery performed by the medical care personnel can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to an operation negative pressure suction device. Background technique [0002] The heart is one of the most important organs in the body of vertebrates. Its main function is to provide pressure for blood flow and to move blood to all parts of the body. The human heart is located at the lower left of the middle of the chest cavity, about the size of a fist, and weighs about 250 grams. Women's hearts are usually smaller and lighter than men's. The human heart is shaped like a peach, located above the diaphragm, between the two lungs and to the left. Heart disease is one of the common diseases in humans. Severe heart disease requires timely surgical treatment, otherwise it will be life-threatening. [0003] During heart surgery, in order to obtain a clearer surgical field, a vacuum suction device for heart surgery is usually used. However, in the existin...
