Description
Technical Field
[0001] This utility model relates to the field of medical clinical technology, and in particular to a drainage device for medical clinical use. Background Technology
[0002] In clinical treatment, drainage is frequently required to remove accumulated fluid from a patient's body. Drainage is the process and method of extracting fluid from a body cavity or wound using suction or gravity. It is commonly used in medical clinical treatment and nursing care.
[0003] In current medical clinical practice, the drainage devices used do indeed have some shortcomings. Their operation procedures are often quite cumbersome, which not only increases the difficulty for medical staff but may also lead to a higher error rate due to the numerous steps. Furthermore, the precision required for these devices during operation needs improvement.
[0004] Insufficient precision often means that, in practice, medical staff struggle to accurately control the speed and volume of drainage, making it difficult to effectively and safely remove fluids from the patient's body. This imprecision can not only lead to inefficient drainage, preventing timely and sufficient removal of fluids, but can also cause unnecessary secondary harm to the patient due to improper operation.
[0005] Specifically, if the fluid is not removed precisely during drainage, some fluid may remain in the patient's body. This residual fluid can become a breeding ground for bacteria, increasing the risk of infection. Furthermore, inaccurate removal can cause additional damage to the patient's tissues, further exacerbating their suffering and making recovery more difficult.
[0006] More seriously, this imprecise drainage procedure can also affect the patient's subsequent treatment process. Residual fluid and tissue damage can interfere with the doctor's assessment of the patient's condition and the formulation of a treatment plan, thus affecting the patient's overall treatment outcome and recovery progress.

[0026] like Figures 1 to 2 As shown, a medical clinical drainage device includes a base 1. A drainage mechanism 2 is fixedly mounted on the upper surface of the base 1. The drainage mechanism 2 includes a drainage pump 21, a power unit 22, and a support frame 23. One side of the drainage pump 21 is connected to a collection cylinder 3 via a first pipe 4. A one-way valve 7 is provided at one end of the first pipe 4 near the collection cylinder 3. The other side of the drainage pump 21 is connected to a drainage head 6 via a second pipe 5. A one-way valve 7 is also provided at one end of the second pipe 5 near the drainage head 6. The one-way valve 7 on the first pipe 4 controls that liquid can only enter the collection cylinder 3 from the drainage pump 21, and the one-way valve 7 on the second pipe 5 controls that liquid can only enter the drainage pump 21 from the drainage head 6.
[0027] like Figure 4 As shown, the lower surface of the drainage pump 21 is fixedly mounted on the upper surface of the base 1. The side wall of the drainage pump 21 has two inlet holes 211 and two outlet holes 212. The two inlet holes 211 are located at the upper and lower ends of the side wall of the drainage pump 21, respectively, and are connected to the second pipe 5. A filter 16 is located at the end of the second pipe 5 near the inlet holes 211. When the accumulated fluid absorbed by the drainage head 6 contains clots, the filter 16 will intercept the clots, allowing the fluid absorption process to proceed smoothly. When the clot content is excessive, the filter 16 can be opened and replaced to prevent blockage during the fluid absorption process. There are also two outlet holes 212, symmetrically positioned to the two inlet holes 211, and each outlet hole 212 is connected to the first pipe 4. The drainage pump 21 is used to drain accumulated fluid, blood clots, and other fluids from the body through the drainage head 6 and into the drainage pump 21.
[0028] Support frames 23 are located on both sides of the drainage pump 21. The lower end of the support frame 23 is fixedly mounted on the upper surface of the base 1, and the upper end of the support frame 23 is connected to the power unit 22. The support plate is used to fix the power unit 22 to prevent the power unit 22 from becoming loose and affecting the operation of the device and causing secondary injury to the patient.
[0029] like Figure 3 As shown, the power unit 22 includes a first motor 221, a second motor 222, a first deflector 223, and a second deflector 224. The output ends of the first motor 221 and the second motor 222 pass through the upper through holes of the support frame 23 and are connected to the first deflector 223 and the second deflector 224, respectively. The first deflector 223 and the second deflector 224 are connected by a first connecting rod 12. The two ends of the first connecting rod 12 are connected to the upper ends of two second connecting rods 13 via bearings. The lower ends of the two second connecting rods 13 are connected to the two ends of a third connecting rod 14 via bearings. The third connecting rod 14 has a circular through hole in the middle. The power unit 22 provides power to the drainage pump 21, enabling the piston 213 inside the drainage pump 21 to move up and down reciprocally to draw out the accumulated fluid inside the patient's body.
[0030] The support frame 23 has a connector 8 on its inner side. The connector 8 has a circular limiting hole in the middle and rectangular limiting holes at both ends. Two second connecting rods are respectively located in the rectangular limiting holes at both ends of the connector 8. The support frame 23 has a control panel 11 on its outer side. The control panel 11 is electrically connected to the first motor 221 and the second motor 222. The control panel 11 is used to control the speed of the first motor 221 and the second motor 222. The built-in chip of the control panel 11 can calculate the volume of liquid drawn by the drainage pump 21 by combining the rotation speed and rotation time of the first motor 221 and the second motor 222 with the area of the piston 213 inside the drainage pump 21 and the vertical movement distance of the piston 213. The volume is then clearly displayed to the operator on the display screen.
[0031] A linkage rod 9 is provided on the upper surface of the piston 213 inside the drainage pump 21. The linkage rod 9 passes through the circular through hole in the middle of the upper surface of the drainage pump 21 and is fixedly connected to the third connecting rod. The upper end of the linkage rod 9 passes through the middle circular limiting hole of the connector 8. The moving rod of the third connecting rod drives the linkage rod 9 to move up and down reciprocally, and the piston 213 inside the drainage pump 21 moves up and down accordingly. The range of motion of the piston 213 inside the drainage pump 21 is between the first liquid inlet hole 211 and the second liquid inlet hole 211. A sealing device 10 is provided at the point where the linkage rod 9 passes through the upper surface of the drainage pump 21. The sealing device 10 is used to prevent external air from entering the drainage pump 21 and disrupting the negative pressure environment inside the drainage pump 21.
[0032] The liquid collecting cylinder 3 has an inlet 31, an outlet 32, and an exhaust port 33 on its side wall. The inlet 31 is connected to the first pipe 4 via a one-way valve 7. The outlet 32 is located at the lower end of the side wall of the liquid collecting cylinder 3 and is connected to a connecting valve 34. The flow rate of the outlet 32 is controlled by rotating the connecting valve 34. The exhaust port 33 is connected to a filter device 35 for filtering the gas discharged from the liquid collecting cylinder 3. A filter screen can be installed inside the liquid collecting cylinder 3. When smaller clumps enter the liquid collecting cylinder 3, the inside of the liquid collecting cylinder 3 can be quickly cleaned by replacing the filter screen.
[0033] The lower surface of the base 1 is provided with a walking unit 15, which includes casters 151 located at the four corners of the base 1. The walking unit 15 enables the device to move easily and flexibly, increasing the device's flexibility and practicality.
[0034] Working principle: The drainage head 6 is placed in the preset area of the patient's body. The volume of fluid to be absorbed is set through the control panel 11. The power unit 22 is started. The first motor 221 and the second motor 222 control the first deflector 223 and the second deflector 224 to rotate, respectively. The first connecting rod 12, the second connecting rod 13, and the third connecting rod 14 work together to drive the linkage rod 9 to move up and down within the limiting hole of the connector 8. The piston 213 inside the drainage pump 21 moves up and down with the linkage rod 9. When moving downwards, the upper part of the pump chamber of the drainage pump 21 is under negative pressure, and the liquid enters the upper pump chamber of the drainage pump 21 through the first inlet hole 211. When the piston 213 moves upwards, the liquid above the pump chamber of the drainage pump 21 enters the collection cylinder 3 through the first outlet hole 212. The lower part of the pump chamber of the drainage pump 21 is under negative pressure, and the liquid enters the lower pump chamber of the drainage pump 21 through the second inlet hole 211. This reciprocating motion achieves the purpose of absorbing the accumulated fluid and other fluids inside the patient's body. The liquid enters the collection cylinder 3 through the drainage pump 21.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
