[0036] Please refer to Figures 1 to 8 .

[0037] The utility model discloses a kind of negative pressure suction and drainage blood tanks 10, including tank body 100;Tank body 100 is the hollow cavity structure of one end encapsulation one end opening.

[0038] The encapsulation end of tank body 100 is provided with negative pressure port 110, and negative pressure port 110 is provided with negative pressure suction nozzle 111;

[0039] The side wall of the tank body 100 is provided with a blood discharge port 120, and the blood discharge port 120 is provided with a blood discharge guide nozzle 121;

[0040] The opening end of the tank body 100 is provided with a sealing ring 130, and the sealing ring 130 is arranged around the opening end of the tank body 100. A sealing ring (not shown in the figure) is sleeved on the sealing ring 130;

[0041] The tank body 100, the negative pressure suction nozzle 111, the blood discharge guide nozzle 121 and the sealing ring 130 are integrally formed;

[0042] The sealing ring 130 is a circular ring structure with a flat end face (as shown in Figures 1 to 4 ), or the sealing ring 130 is a circular ring structure with an arc-shaped curved end face (as shown in Figures 5 to 8 ).

[0043] In this embodiment, the tank body 100 is preferably a transparent glass structure. In other embodiments, the tank body 100 can also be a transparent plastic structure. Regardless of the material of the tank body 100, it needs to be able to ensure good sealing and transparency, so as to facilitate observation of the internal condition of the tank body 100.

[0044] In this embodiment, the tank body 100 has a tank body part 101 and a tank top part 102 connected in one body. The tank body part 101 is a circular cylindrical structure, the tank top part 102 is a hemispherical cavity structure, and the center axis of the tank body part 101 and the center axis of the tank top part 102 are on the same straight line. The negative pressure port 110 is arranged at the center axis of the tank top part 102. The blood discharge port 120 is arranged at the position of the tank body part 101 close to the sealing ring 130.

[0045] In this embodiment, the center axis of the sealing ring 130 and the center axis of the tank body part 101 are on the same straight line. The diameter of the sealing ring 130 is greater than the diameter of the tank body part 101.

[0046] Further, the negative pressure suction and blood discharge tank 10 further comprises a positive and negative pressure device (not shown in the figure), which is connected with the negative pressure suction nozzle 111 through a hose. The positive and negative pressure device inhales to make the tank body 100 produce negative pressure, and the positive and negative pressure device blows to make the tank body 100 produce positive pressure.

[0047] Further, the negative pressure suction and blood discharge tank 10 further comprises a blood storage vessel (not shown in the figure), which is connected with the blood discharge guide nozzle 121 through a hose.

[0048] Further, the tank body part 101 is engraved with scale lines (not shown in the figure).

[0049] Next, the use method and working principle of the negative pressure suction and blood discharge tank 10 described above will be described:

[0050] In the use of negative pressure suction blood tank 10, the skin surface of the human body has been pierced by the physiotherapy needle, in the state of waiting for blood;

[0051] The open end of the tank body 100 is pressed on the pierced skin surface of the human body, and the positive and negative pressure device has been connected with the negative pressure suction nozzle 111 through the hose at this time, and the blood storage container cannot be connected with the blood drainage guide nozzle 121 temporarily;

[0052] The doctor blocks the blood drainage guide nozzle 121 with fingers, starts the positive and negative pressure device, and makes the positive and negative pressure device inhale to generate negative pressure;

[0053] Under the action of the negative pressure of the tank body 100, the blood stasis in the human body tissue is sucked out of the tank body 100, and the current blood stasis state can be clearly seen through the transparent tank body 100, and the amount of blood stasis extracted at present can be read through the scale line on the tank body 101;

[0054] When the amount of blood stasis in the tank body 100 reaches a certain degree, the doctor can quickly remove the fingers originally blocked at the blood drainage guide nozzle 121, so that the internal and external pressures of the tank body 100 are balanced;

[0055] Then, the blood storage container is connected with the blood drainage guide nozzle 121 through the hose, the positive and negative pressure device blows to make the tank body 100 generate positive pressure, so that the blood stasis in the tank body 100 can be drained to the blood storage container through the blood drainage guide nozzle 121; since the blood drainage guide nozzle 121 is a certain height away from the bottom of the tank body, it is the blowing action of the positive and negative pressure device that can more fully drain the blood stasis.

[0056] After the blood stasis in the tank body 100 is completely drained to the blood storage container, the positive and negative pressure device is closed, and the tank body 100 is removed from the skin surface of the human body, so that the blood stasis in the tank body can be drained without causing overflow.

[0057] It should be particularly pointed out that in the utility model, the blood drainage guide nozzle 121 is not only used for draining the blood stasis in the tank body, but also used for cooperating with the fingers of the doctor to form blocking to make the tank body generate negative pressure, once the amount of blood stasis in the tank body reaches a specified value, the fingers of the doctor can be very quickly removed from the blood drainage guide nozzle 121, precise control is realized, the hysteresis phenomenon in the process of negative pressure blood extraction is reduced, and then the positive and negative pressure device and the blood storage container are operated in order, so that the doctor does not feel flustered.

[0058] It should be further pointed out that in the utility model, the sealing ring 130 is a circular ring structure with a flat end face, or the sealing ring 130 is a circular ring structure with an arc-shaped curved end face, so that the sealing ring 130 has different shape structures, different tank bodies 100 can be adaptively used according to different parts of the human body, and better effects can be obtained.

[0059] The sealing ring is sleeved on the sealing ring 130, so that better sealing effect can be obtained.

[0060] The can body part 101 is a circular cylinder structure, and the can top part 102 is a hemispherical cavity structure, so that better gripping feeling can be obtained.

[0061] The negative pressure blood suction and discharge can reduces the hysteresis phenomenon in the negative pressure blood drawing process, and can discharge the blood stasis in the can body without causing overflow.

[0062] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be pointed out that, for ordinary skilled in the art, without departing from the utility model concept, a number of deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
