[0021] Specifically, the filter box 5 is made of transparent plastic material.
[0022] In this embodiment, the transparent material makes it easy to check the status of the filter box 5 and to prevent blockage. If blockage occurs, the filter box 5 can be tilted to allow debris to accumulate in a certain place.
[0023] Specifically, the suction mechanism 8 includes a first plug-in component 801, a handle tube 802 and a suction head 803. The first plug-in component 801 is installed on the right end of the first hose 7. The handle tube 802 is fixedly installed on the right end of the first plug-in component 801, and the suction head 803 is installed on the right side of the handle tube 802.
[0024] In this embodiment, the first plug-in assembly 801 is plugged and fixed with the first hose 7 , the handle tube 802 is held by hand, and the blood from the affected area is sucked through the suction head 803 , so that the blood flows into the filter box 5 through the handle tube 802 and the first hose 7 .
[0025] Specifically, the collecting mechanism 10 includes a second plug-in component 101, a collecting bucket 102, a second filter 103 and a plug-in plate 104. The second plug-in component 101 is installed on the left side of the second hose 9. The collecting bucket 102 is installed on the upper end of the second plug-in component 101. The second filter 103 is installed between the inner walls of the collecting bucket 102. The plug-in plate 104 is fixedly installed on the left side of the collecting bucket 102.
[0026] In this embodiment, the second plug-in assembly 101 plugs and fixes the collecting bucket 102 with the second hose 9 , and the blood dripping from the affected area in the collecting bucket 102 flows into the second hose 9 and then flows into the filter box 5 through the second hose 9 .
[0027] Specifically, the upper surface of the collecting hopper 102 is an open structure, and the lower side wall of the collecting hopper 102 is a conical structure.
[0028] In this embodiment, the blood in the collecting bucket 102 flows quickly into the second hose 9 .
[0029] Specifically, the extraction mechanism 12 includes a third plug-in component 121, a conduit 122 and an exhaust fan 123. The third plug-in component 121 is installed on the waterproof breathable valve 11, the conduit 122 is fixedly installed on the waterproof breathable valve 11, and the upper end of the conduit 122 is connected to the air inlet of the exhaust fan 123.
[0030] In this embodiment, the third plug-in component 121 is plugged and fixed to the waterproof breathable valve 11, so that the exhaust fan 123 evacuates the waterproof breathable valve 11 through the conduit 122. The waterproof breathable valve 11 draws negative pressure from the filter box 5, so that the filter box 5 evacuates the suction mechanism 8 and the collection mechanism 10.
[0031] When in use, the first plug-in assembly 801 is plugged and fixed to the first hose 7, the second plug-in assembly 101 connects and fixes the collecting bucket 102 to the second hose 9, and the third plug-in assembly 121 is plugged and fixed to the waterproof breathable valve 11. At the same time, according to the craniotomy position, the plug plate 104 in the collecting mechanism 10 is inserted at the lower side of the affected part, and then the exhaust fan 123 in the extraction mechanism 12 is used to evacuate the waterproof breathable valve 11 through the conduit 122. The waterproof breathable valve 11 evacuates the negative pressure in the filter box 5, so that the filter box 5 evacuates the suction mechanism 8 and the collecting mechanism 10. The handle tube 802 in the suction mechanism 8 is held by hand, and the blood of the affected part is sucked through the suction head 803, so that the blood passes through the handle tube 802 and the first hose 7. The blood flows into the filter box 5, and the blood from the affected area drips into the collection bucket 102 of the collection mechanism 10. The second filter screen 103 filters the blood, and the filtered blood in the collection bucket 102 flows into the second hose 9, and then flows into the filter box 5 through the second hose 9. The blood in the filter box 5 flows to the one-way liquid inlet valve 4 after passing through the first filter screen 6, and flows into the collection bag body 1 through the one-way liquid inlet valve 4, so that the blood collection bag has two blood collection methods, which makes the blood collection efficiency higher and avoids blood splashing. It can also filter the debris in the blood to avoid the debris from entering the collection bag body 1, so that the amount of blood in the collection bag body 1 can be checked more clearly, that is, the patient's blood loss can be monitored, which is convenient for subsequent treatment of the patient.
[0032] In summary, the blood collection bag has two blood collection methods, namely the suction mechanism 8 and the collection mechanism 10. At the same time, negative pressure is formed between the collection bucket 102 and the suction head 803, which accelerates blood flow, makes blood collection more efficient, avoids blood splashing, and can filter debris in the blood, so as to more clearly check the amount of blood in the collection bag main body 1, which is convenient for subsequent treatment of patients.
