Problems solved by technology

[0005] 1) The skin fixer proposed by it has poor fixing effect, and it is easy to cause the thin drainage catheter to fall off from the patient's chest cavity, which not only affects the treatment effect, but also seriously threatens the life safety of the patient;
[0006] 2) The drainage bag used in the process of use has no negative pressure inside, which leads to poor drainage effect, which affects the treatment effect;
[0007] 3) Its antibacterial performance is poor, it is easy to nourish bacteria and produce peculiar smell during use, and the hygienic condition of use is poor

Embodiment 1

[0054] A thin catheter closed drainage device for pleural fluid, such as figure 1 As shown, it includes a thin drainage catheter 1, a liquid storage unit 2, a negative pressure generating unit 3, a catheter switch 4, and a fixing unit 5. Both ends of the thin drainage catheter 1 are open ends, and the liquid storage unit 2 is connected and installed. At one end of the thin drainage catheter 1 , the negative pressure generating unit 3 and the liquid storage unit 2 are in communication with each other, and the catheter switch 4 and the fixing unit 5 are both sleeved on the outside of the thin drainage catheter 1 , and the catheter switch 4 is located between the fixing unit 5 and the liquid storage unit 2 , and the end of the thin drainage catheter 1 away from the liquid storage unit 2 is a free end.

[0055] By adopting the above technical scheme, the free end of the thin drainage catheter 1 is used to put into the patient's thorax to drain and discharge the effusion inside the...

Embodiment 2

[0075] The difference from Example 1 is that the inner and outer surfaces of the liquid storage bottle 6 are provided with a protective layer, and the protective layer is prepared by the following method:

[0076] Take the following raw materials and weigh them by weight: 18 parts of epoxy resin, 12 parts of calcium carbonate powder, 10 parts of copper oxide powder, 10 parts of titanium dioxide powder, 12 parts of nano-silver powder, 2 parts of alcohol ester twelve, 2 parts of triethanolamine, emulsified 2 parts of silicone oil and 30 parts of water;

[0077] S1. Add the weighed alcohol ester dodecane, triethanolamine, emulsified silicone oil and water into the mixer and stir for 20min at a stirring speed of 500r / min to prepare a mixed solution;

[0078] S2, adding epoxy resin, calcium carbonate powder, copper oxide powder, titanium dioxide powder and nano-silver powder into the pulverizer and pulverizing until the particle diameter of the material is not greater than 100nm, s...

Embodiment 3

[0083] The difference with embodiment 2 is the preparation of protective layer, and its specific preparation method is as follows:

[0084] Take the following raw materials and weigh them by weight: 23 parts of epoxy resin, 14 parts of calcium carbonate powder, 12 parts of copper oxide powder, 12 parts of titanium dioxide powder, 13 parts of nano-silver powder, 3 parts of alcohol ester twelve, 3 parts of triethanolamine, emulsified 3 parts of silicone oil and 35 parts of water;

[0085] S1. Add the weighed alcohol ester dodecane, triethanolamine, emulsified silicone oil and water into the mixer and stir for 25min at a stirring speed of 550r / min to prepare a mixed solution;

[0086] S2, adding epoxy resin, calcium carbonate powder, copper oxide powder, titanium dioxide powder and nano-silver powder into the pulverizer and pulverizing until the particle diameter of the material is not greater than 100nm, so as to obtain a mixed powder material;

[0087] S3. Add the mixed soluti...

Abstract

The invention discloses a thin-catheter closed type chest fluid drainage device, which comprises a drainage thin catheter, a fluid storage unit, a negative pressure generation unit, a catheter switchand a fixing unit, wherein two ends of the drainage thin catheter are both opening ends; the fluid storage unit is in communication installation on one end of the drainage thin catheter; the negativepressure generation unit and the fluid storage unit are in communication connection; the catheter switch and the fixing unit are both sheathed out of the drainage thin catheter; in addition, the catheter switch is positioned between the fixing unit and the fluid storage unit; and one end, which is far away from the fluid storage unit, of the drainage thin catheter is a free end. By use of the thin-catheter closed type chest fluid drainage device, negative pressure suction is used so as to be favorable for successfully draining and discharging hydrops in the chest of a patient, a drainage effect is good, a treatment effect is effectively guaranteed, the drainage thin catheter can be prevented from falling from the chest of the patient, the life safety of the patient is effectively guaranteed, a prepared protection layer can avoid a situation that a great quantity of bacteria is bred on the inner surface and the outer surface of a fluid storage bottle to generate peculiar smells, and a use sanitary condition is good.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a thin catheter closed drainage device for pleural fluid. Background technique [0002] Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position, so as to expel air or collect fluid in the chest cavity, allowing the lung tissue to reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases. [0003] The Chinese patent with the existing application number CN01252632.0 discloses a thin catheter closed drainage pleural fluid device, which is mainly composed of a thin drainage catheter, a connector, and a drainage bag with a scale. The specific connection is the drainage thin catheter and the connection Th...
