In this embodiment, the first filler 13 is a buffer material, and in this embodiment, the first filler 13 is polyester fiber, which has good buffering performance and can prevent the diversion funnel 4 from being pressed and deformed.
At present, the operation bed for the obstetrics and gynecology department is provided with an opening for discharging blood, the aperture of the flow guide tube 5 of the embodiment is smaller than that of the operation bed for the obstetrics and gynecology department, so that the flow guide tube 5 penetrates through the opening of the operation bed at one end of the cushion body 1.
The collecting container 6 is connected with one end of the draft tube 5 far away from the concave surface 101 through a connecting tube 61, and the collecting container 6 is provided with scale marks 62. The scale mark 62 can be convenient for medical personnel to observe the amount of bleeding of lying-in woman to can accurately carry out the blood transfusion for lying-in woman, avoid the insufficient and excessive problem that appears of blood transfusion volume. In this embodiment, collection container 6 is made for transparent material, preferably adopts transparent plastic material, can be convenient for medical personnel observe the blood volume in the collection container.
In this embodiment, the connecting tube 61 is a corrugated tube, and both ends are respectively screwed with the flow guide tube 5 and the collecting container 6. The connection pipe 61 is a bellows pipe so that the length of the connection pipe 61 can be adjusted, thereby adjusting the length of the connection pipe 61 in accordance with the height of the operating bed so that the collection container 6 can be placed on the ground.
Because the pad body is equipped with concave surface 101 for guide layer 2 laid on concave surface 101 has the structure of sinking in pad body 1 inside, and the blood that the patient leaked can flow to water conservancy diversion funnel 4 through guide layer 2, and blood gets into collection container 6 from connecting pipe 61 thereupon, avoids bed clothes to be polluted by blood, effectively reduces the possibility of woman vaginal infection, can avoid lying-in woman's excessive bleeding volume again simultaneously and lead to blood to flow to ground. Guide layer 2 is connected with concave surface 101 through first magic subsides 22, and honeycomb duct 4 is connected with keeping off through second magic subsides 51 and separate cloth 12 to make things convenient for blood collection device's dismantlement, reduce the clean degree of difficulty of cotton-padded mattress quilt.
In this embodiment, the draft tube 5 is further sleeved with a buffer spring 52, and the buffer spring 52 is located in the placing bin 11 and has two ends fixedly connected to the draft tube 5. Honeycomb duct 5 is the bellows and the cover is equipped with buffer spring 52, and its support nature that can improve honeycomb duct 5 avoids the lying-in woman to roll over honeycomb duct 5, guarantees that the blood of outflow can flow into connecting pipe 61 by honeycomb duct 5 smoothly, arranges into in the collecting vessel 6 at last.
Because the two ends of the connecting pipe 61 are respectively in threaded connection with the guide pipe 5 and the collecting container 6, when the guide layer 2, the guide piece 4 and the guide pipe 5 need to be disassembled and replaced, the connecting pipe 61 can be screwed to separate the connecting pipe 61 from the guide pipe 5, so that the guide layer 2, the guide piece 4 and the guide pipe 5 can be conveniently disassembled from the cushion body 1.
When the blood drainage mattress for obstetrical surgery of the embodiment is used, the mattress body 1 is laid on an operation bed, and the flow guide pipe 5 penetrates through one end of the mattress body 1 and penetrates through an opening of the operation bed. Both ends of the connection pipe 61 are screwed to the draft tube 5 and the collection container 6, respectively, and the collection container 6 is set on the ground by adjusting the length of the connection pipe 61. Lying on the pad body 1 and laying the buttocks on the buttocks pad 201, during operation, the blood leaked from the puerpera can flow to the diversion member 4 through the guide layer 2, and then the blood enters the collection container 6 from the connecting pipe 61.
When blood collection device after the use is dismantled to needs, twist and move connecting pipe 61 and make the both ends of connecting pipe 61 separate with honeycomb duct 5 and collection container 6 respectively, tear first magic subsides 22 and separate guide layer 2 and concave surface 101, tear second magic subsides 51 after taking out the first filler 13 of placing in the storehouse 11, make honeycomb duct 5 with keep off and separate cloth 12 separation, thereby make honeycomb duct 5 and diversion funnel 4 can take out in placing storehouse 11, blood collection device's dismantlement has been realized.
