Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a portable medical liquid collection device. Background Art

[0002] The medical industry is the cornerstone of social health and safety and is directly related to everyone's quality of life and well-being. It not only plays a core role in disease treatment and rehabilitation services, but also undertakes the important task of preventive care and health education. It is of great significance to improving the health level of the whole people and promoting social and economic development.

[0003] The treatment of medical waste liquids is an important part of medical waste management because they may carry pathogens such as bacteria, viruses, etc. If not handled properly, they may pose a threat to human health and the environment. Therefore, medical institutions need to take appropriate measures to safely and effectively treat these waste liquids to prevent disease transmission and environmental pollution.

[0004] When using the current liquid collection device, it is necessary to first absorb the liquid produced by the patient during surgery or medical treatment. These liquids are usually regarded as waste liquids. These waste liquids contain blood, body fluids, drug residues, disinfectants or other substances that may be harmful to the human body or the environment. Therefore, after the waste liquid is absorbed, it needs to be centrally processed, so the staff is required to discharge the absorbed waste liquid in a designated area. Currently, when absorbing the waste liquid, it is usually absorbed through a syringe, so the processing process is cumbersome, and if the protective measures are not in place when discharging the waste liquid, the staff may directly contact the waste liquid, increasing the risk of infection, so it needs to be improved and optimized. Summary of the invention

[0021] When it is necessary to collect waste liquid, the staff can first disinfect the device and then move it to the appropriate position through the handle 2. Then the staff will install the disposable liquid collection bag 3. First, the staff will align the positioning block 5 with the slot on the right rear side of the placement rack 1, and ensure that the connecting port 4 is located above the placement rack 1, and then press the positioning block 5 into the slot. Furthermore, due to the setting of the two sets of inclined wedges 21, when the positioning block 5 enters the slot, the inclined wedge 21 will be squeezed by the outer wall of the positioning block 5 and received in the guide groove 20. When the positioning block 5 is completely installed, the inclined wedge 21 will be reset by the elastic potential energy of the arc spring 29 to complete the installation of the positioning block 5. After the installation of the positioning block 5 is completed, the staff picks up the syringe 7 and aligns the suction nozzle 9 with the position where the waste liquid needs to be sucked, and then passes The piston rod 11 lifts the piston plate 12 upward along the limit groove 10. Further, when the piston plate 12 is lifted, due to the change in differential pressure between the inside and the outer wall of the syringe 7, the first plug 14 will be pulled upward. At this time, the suction nozzle 9 is opened, and the waste liquid will be sucked into the inside of the syringe 7 through the suction nozzle 9. After a single waste liquid suction is completed, the staff presses the piston rod 11 downward to reset the piston plate 12 downward. Further, the first plug 14 will seal the suction nozzle 9 again downward through the elastic potential energy of the first spring 15, and the waste liquid will squeeze the second plug 17 to open the delivery pipe 8. Furthermore, the waste liquid will flow into the inside of the hose 6 through the delivery pipe 8, and finally be injected into the disposable liquid collection bag 3 to complete the collection. It is worth noting that the disposable liquid collection bag 3, hose 6 and syringe 7 are all disposable.

[0022] The piston plate 12 is pulled up and down by the piston rod 11. When the piston plate 12 moves upward, the waste liquid will enter the interior of the syringe 7 from the suction nozzle 9. When the piston plate 12 moves downward, the waste liquid will be injected into the disposable liquid collecting bag 3 through the hose 6, thereby completing the storage and collection of the waste liquid. Compared with the traditional device, the device, through the setting of the disposable liquid collecting bag 3, the hose 6 and the syringe 7, enables the staff to quickly suck the waste liquid into the disposable liquid collecting bag 3 for storage, and the operation is simple. In addition, the device is improved from a disposable injection, has low cost, is easy to carry, and effectively improves the safety and efficiency of the staff when collecting liquid.

[0023] Among them, two groups of rotating rods 22 are rotatably installed inside the control compartment 19, and transmission rods 23 are fixedly installed on the outer walls of the two groups of rotating rods 22. Pull rods 24 are rotatably installed on the other ends of the two groups of transmission rods 23. The two groups of pull rods 24 are rotatably connected to the inclined wedges 21. The outer walls of the two groups of rotating rods 22 are provided with teeth 25, and the two groups of rotating rods 22 are meshed with each other through the teeth 25.

[0024] After absorbing waste liquid many times, the disposable liquid collecting bag 3, hose 6 and syringe 7 need to be replaced. At this time, the staff turns the knob 30 with one hand to rotate the pressure rod 26, and the arc spring 29 is further compressed, and the pressure rod 26 will drive one group of rotating rods 22 to rotate, and the two groups of rotating rods 22 are connected by the teeth 25, so that the two groups of rotating rods 22 rotate synchronously in opposite directions, and the rotation of the rotating rod 22 will drive the transmission rod 23 to rotate, and the transmission rod 23 will further pull the inclined wedge 21 into the guide groove 20 through the pull rod 24, so that the staff's other hand can easily remove the disposable liquid collecting bag 3, and when the staff releases the knob 30, the pressure rod 26 will be reset by the elastic potential energy of the arc spring 29, and through the transmission of the rotating rod 22 and the transmission rod 23, the pull rod 24 will reset the inclined wedge 21, preparing for the installation of the next group of disposable liquid collecting bags 3.

[0025] By setting two groups of rotating rods 22 inside the placement rack 1, when the staff rotates a single group of rotating rods 22, the two groups of rotating rods 22 rotate synchronously in opposite directions, and the transmission rod 23 further controls the displacement of the inclined wedge 21 through the pull rod 24, and after the staff releases the knob 30, the inclined wedge 21 will be reset by the elastic potential energy of the arc spring 29. Compared with the traditional device, the device can quickly replace the disposable liquid collection bag 3, the hose 6 and the syringe 7, thereby ensuring the collection efficiency of the waste liquid.

It is worth mentioning that the positioning ring 32 and the fixing pad 35 are magnetically connected by the first magnetic block 33 and the second magnetic block 34. The purpose is to ensure that the waste collecting barrel 31 can be firmly placed on the placement rack 1 when the staff moves the placement rack 1.

[0028] Through the provision of the waste collecting barrel 31, the staff can remove the disposable liquid collecting bags 3 and discard them in the waste collecting barrel 31 after a single set of disposable liquid collecting bags 3 is full, thereby avoiding cross infection caused by littering of waste liquid, and also making it convenient for the staff to carry out centralized treatment of the disposable liquid collecting bags 3. At the same time, the device also facilitates the staff to disassemble and assemble the waste collecting barrel 31 through the provision of the first magnetic block 33 and the second magnetic block 34, ensuring that the waste collecting barrel 31 can be stably placed on the placement rack 1 when the staff moves the placement rack 1, thereby improving user satisfaction during use.

[0032] When the pressure rod 26 rotates, the arc spring 29 is compressed, and the two sets of baffles 28 are used to limit the pressure rod 26 .

[0033] The inner wall of the housing 27 is provided with two groups of baffles 28 , and the outer wall of the pressure rod 26 is provided with protrusions corresponding to the positions of the two groups of baffles 28 .

[0034] The pressure rod 26 and the baffle 28 are elastically connected via an arc spring 29 , and a knob 30 is rotatably mounted on the top of the housing 27 , and the knob 30 and the pressure rod 26 are fixedly connected.

[0035] When the staff releases the knob 30 , the pressure rod 26 will be reset by the elastic potential energy of the arc spring 29 , and through the transmission of the rotating rod 22 and the transmission rod 23 , the pull rod 24 will reset the inclined wedge 21 .

[0036] The two groups of transmission rods 23 are cross-arranged inside the control compartment 19 , and the two groups of transmission rods 23 are staggered in height.

[0037] Working principle and usage process: When it is necessary to collect waste liquid, the staff can first disinfect the device and then move it to the appropriate position through the handle 2. Then the staff will install the disposable liquid collection bag 3. First, the staff will align the positioning block 5 with the slot on the right rear side of the placement rack 1, and ensure that the connecting port 4 is located above the placement rack 1, and then press the positioning block 5 into the slot. Furthermore, due to the setting of the two sets of inclined wedges 21, when the positioning block 5 enters the slot, the inclined wedge 21 will be squeezed by the outer wall of the positioning block 5 and received in the guide groove 20. When the positioning block 5 is completely installed, the inclined wedge 21 will be reset by the elastic potential energy of the arc spring 29 to complete the installation of the positioning block 5. After the installation of the positioning block 5 is completed, the staff picks up the syringe 7 and aligns the suction nozzle 9 with the position where the waste liquid needs to be sucked, and then passes The piston rod 11 lifts the piston plate 12 upward along the limit groove 10. Further, when the piston plate 12 is lifted, due to the change in differential pressure between the inside and the outer wall of the syringe 7, the first plug 14 will be pulled upward. At this time, the suction nozzle 9 is opened, and the waste liquid will be sucked into the inside of the syringe 7 through the suction nozzle 9. After a single waste liquid suction is completed, the staff presses the piston rod 11 downward to reset the piston plate 12 downward. Further, the first plug 14 will seal the suction nozzle 9 again downward through the elastic potential energy of the first spring 15, and the waste liquid will squeeze the second plug 17 to open the delivery pipe 8. Furthermore, the waste liquid will flow into the inside of the hose 6 through the delivery pipe 8, and finally be injected into the disposable liquid collection bag 3 to complete the collection. It is worth noting that the disposable liquid collection bag 3, hose 6 and syringe 7 are all disposable.

[0038] After absorbing waste liquid many times, the disposable liquid collecting bag 3, hose 6 and syringe 7 need to be replaced. At this time, the staff turns the knob 30 with one hand to rotate the pressure rod 26, and the arc spring 29 is further compressed, and the pressure rod 26 will drive one group of rotating rods 22 to rotate, and the two groups of rotating rods 22 are connected by the teeth 25, so that the two groups of rotating rods 22 rotate synchronously in opposite directions, and the rotation of the rotating rod 22 will drive the transmission rod 23 to rotate, and the transmission rod 23 will further pull the inclined wedge 21 into the guide groove 20 through the pull rod 24, so that the staff's other hand can easily remove the disposable liquid collecting bag 3, and when the staff releases the knob 30, the pressure rod 26 will be reset by the elastic potential energy of the arc spring 29, and through the transmission of the rotating rod 22 and the transmission rod 23, the pull rod 24 will reset the inclined wedge 21, preparing for the installation of the next group of disposable liquid collecting bags 3.

[0039] During treatment or surgery, after replacing a single set of disposable liquid collecting bags 3, the staff can discard the discarded disposable liquid collecting bags 3, hoses 6 and syringes 7 in the waste collecting barrel 31. The staff can set a medical waste bag inside the waste collecting barrel 31 to collect waste liquid and waste products. When the waste collecting barrel 31 needs to be cleaned and disinfected, the staff only needs to lift the waste collecting barrel 31 upward to separate the second magnetic block 34 and the first magnetic block 33 from each other, thereby completing the disassembly of the waste collecting barrel 31. It is worth mentioning that the positioning ring 32 and the fixing pad 35 are magnetically connected by the first magnetic block 33 and the second magnetic block 34.
