Description

Technical Field

[0001] The utility model relates to the technical field of medical effusion treatment equipment, in particular to a medical chest effusion extraction device. Background Art

[0002] The human endocrine system secretes various hormones, and together with the nervous system, it regulates the body's metabolism and physiological functions. Under normal circumstances, various hormones are kept in balance. If this balance is broken for some reason, it will cause endocrine disorders, which will cause corresponding clinical reactions, such as effusion in the chest and abdominal cavities. In clinical practice, endocrine extraction devices are mostly used to extract the effusion. Most existing effusion extraction devices use manual extraction, which has low controllability and cannot be well controlled. The operation is complicated when extracting effusion, the accuracy is low, and it is easy to be contaminated by the effusion.

[0003] In response to the above problems, the existing national publication number: CN209790472U "An Endocrine Fluid Extraction Device" uses the addition of motors and other equipment to replace manual extraction, which can effectively improve accuracy. However, in actual use, common equipment on the market and the above-mentioned equipment still have a certain degree of stability. For example, during the extraction process, the negative pressure generated by the vacuum pump is fixed. When facing patients with high fluid concentrations, the effusion is difficult to be effectively sucked out. When facing patients with low fluid concentrations, it is difficult to control the speed and strength of suction, which can easily cause damage to the patient. Therefore, it has the defect of poor applicability. Secondly, most of them use a needle to insert into the patient's body to extract fluid, but in the actual extraction process, the needle is easily blocked by the tissue in the patient's body or blocked by the higher concentration of effusion, which has the disadvantage of being difficult to complete the extraction efficiently and smoothly.

The medical chest effusion extraction device is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] See also Figure 1-6 In the present embodiment, a medical chest effusion extraction device is provided, comprising: a main body 1, a liquid extraction chamber 101 is provided inside the main body 1, a vent is provided at the top of the liquid extraction chamber 101, a piston 102 is slidably connected inside the liquid extraction chamber 101, an electric push rod 103 is provided at the top of the main body 1, and the bottom of the electric push rod 103 is connected to the piston 102; a liquid extraction tube 3, the liquid extraction tube 3 is arranged at one side of the main body 1, and a needle 4 is arranged at the end of the liquid extraction tube 3; an anti-blocking component, the anti-blocking component is arranged between the liquid extraction tube 3 and the needle 4, and is used to prevent the needle 4 and the liquid extraction tube 3 from being blocked and improve the adsorption efficiency; and an adjusting component, the adjusting component is arranged inside the main body 1, and is used to adjust the adsorption force of the device;

[0027] During use, the user can insert the needle 4 into the patient's body and start the electric push rod 103 to drive the piston 102 to move inside the liquid extraction chamber 101, so as to create negative pressure, and absorb the accumulated fluid in the needle 4 and the patient's body under the negative pressure state, so as to complete the extraction of the accumulated fluid. During the extraction process, when there is too much accumulated fluid or it is too viscous and the adsorption force needs to be increased, the adjustment component can be used to increase the adsorption force of the device. When the needle 4 is blocked by tissue, the user can use the anti-blocking component to push the tissue block to move, so as to complete the effective anti-blocking and improve the practicality of the device.

[0028] The anti-blocking component includes: an adjusting head 301 disposed between the end of the liquid extraction tube 3 and the needle 4, an adjusting groove 302 is provided on the inner wall of the adjusting head 301; an adjusting block 304 slidably connected to the inside of the adjusting groove 302, a push rod 308 is connected to one side of the adjusting block 304, an adjusting ring 306 is provided at the end of the push rod 308, the adjusting ring 306 is slidably connected to the needle 4, a plurality of auxiliary ports 307 are provided on both sides of the adjusting ring 306, and the inside of the auxiliary port 307 is arranged in a funnel-shaped structure;

[0029] During use, when tissue blocks or high-concentration effusion are blocked on the needle 4, the user can push the adjustment block 304 to drive the push rod 308 to move. At this time, the adjustment ring 306 at the end of the push rod 308 will protrude from the needle 4, and the tissue blocks blocked on the needle 4 will be withdrawn from the needle 4. At the same time, the multiple funnel-shaped auxiliary ports 307 on both sides of the adjustment ring 306 can replace the needle port of the needle 4 to continue to complete the extraction. In the above manner, the needle 4 can achieve an anti-blockage effect, thereby improving the convenience of use of the device.

[0030] Among them, leakage-proof grooves 303 are opened on the inner walls of both sides of the adjustment groove 302, and leakage-proof plates 305 are provided on both sides of the adjustment block 304, and the leakage-proof grooves 303 and the leakage-proof plates 305 are slidably connected;

[0031] During use, the user can clear the blockage of the needle 4 by pushing the adjusting block 304. When the user pushes the adjusting block 304, the leak-proof plate 305 will move inside the leak-proof groove 303. At this time, the mutual engagement between the movable leak-proof plate 305 and the leak-proof groove 303 can seal the adjusting groove 302 to prevent the outside air and accumulated fluid from flowing into or out of the adjusting groove 302 during use, thereby improving the air tightness of the device.

[0032] Furthermore, a plurality of anti-slip grooves are provided on the side of the adjustment block 304 away from the main body 1, and the plurality of anti-slip grooves are equidistantly distributed. During use, the blockage is cleared by pushing the adjustment block 304, and the plurality of anti-slip grooves provided on one side of the adjustment block 304 can increase the friction between the user's fingers and the adjustment block 304, allowing the user to push the adjustment block 304 to slide more conveniently and quickly.

[0033] Example 2

[0034] like Figure 1-Figure 4 As shown, on the basis of Example 1, the adjustment component includes: a pressurizing chamber 104 opened on both sides of the main body 1, and a pressurizing plate 2 is slidably connected inside the pressurizing chamber 104; a driving motor 202 is arranged on the inner wall of the pressurizing chamber 104, and a threaded rod 203 is connected to one side of the driving motor 202 through a driving shaft, and the threaded rod 203 is meshedly connected with the pressurizing plate 2;

[0035] During use, the method of increasing the internal space of the pumping chamber 101 is used to create negative pressure inside the pumping chamber 101 to generate attraction. When the patient's chest effusion concentration is high and difficult to pump, the user can start the drive motor 202 to drive the threaded rod 203 to rotate before pumping fluid from the patient. At this time, the rotating threaded rod 203 can continuously engage with the pressure plate 2, allowing the pressure plate 2 to slide inside the pressure chamber 104, reducing the space connecting the pressure chamber 104 and the pumping chamber 101, so that the negative pressure generated inside the pumping chamber 101 can be further increased during the subsequent pumping process. This method can prevent the situation where the adsorption pressure is insufficient and the device is difficult to complete the adsorption, thereby improving the practicability of the device.

[0036] A limiting groove 105 is provided on the inner wall of the top of the pressurizing chamber 104, a limiting block 201 is provided on the top of the pressurizing plate 2, and the limiting block 201 is slidably connected to the limiting groove 105;

[0037] During use, the pressurization is completed by sliding of the pressure plate 2. During the sliding process, the pressure plate 2 can be restricted by sliding between the limit block 201 and the limit groove 105 to prevent the pressure plate 2 from deviating during sliding and causing air leakage, which makes it difficult for the device to maintain negative pressure to complete adsorption.

[0038] An air inlet pipe 106 is provided on the inner wall of one side of the pressurizing chamber 104, a blower 107 is provided inside the air inlet pipe 106, an air pipe 108 is connected to one side of the air inlet pipe 106, a pad 204 is provided on the edge of the pressurizing plate 2, the end of the air pipe 108 is connected to the pad 204, and the air pipe 108 is communicated with the inside of the pad 204;

[0039] During use, after the position of the pressure plate 2 is adjusted, air can be blown toward the inside of the air pipe 108 through the blower 107, and the airflow will reach the pad 204 along the air pipe 108. At this time, the pad 204 is filled with the airflow, so the pad 204 will continue to expand in the inflated state and fit against the inner wall of the pressure chamber 104. During the fitting process, it can effectively prevent the existence of a gap between the pressure chamber 104 and the pressure plate 2, thereby improving the airtightness of the pressure plate 2.

[0040] Among them, multiple sealing strips 205 are provided on the surface of the gasket strip 204, and the gasket strip 204 and the sealing strip 205 are both made of rubber material. During the pressurized filling process, the sealing strip 205 can be used to pad the inner wall of the pressurized chamber 104, further sealing the gap between the gasket strip 204 and the pressurized chamber 104, which can further improve the sealing effect.

[0041] The above is a detailed introduction to a medical chest effusion extraction device provided in an embodiment of the present application.
