Embodiment 1

[0018] Such as figure 1 , figure 2 As shown, a pressurized and adjustable infusion bag includes a bag body 1, the bottom of the bag body 1 is connected with an infusion tube 11, the top of the bag body 1 is provided with a high-pressure air bag 2 integrated with the bag body 1, and one side of the high-pressure air bag 2 is provided with an air outlet tube 21. The shape of the air outlet pipe 21 is conical, and the tapered part of the air outlet pipe 21 is in sealing connection with the high-pressure air bag 2. The inner diameter of the tapered part of the air outlet pipe 21 can be 2 mm to 5 mm, especially 2 mm to 3 mm. Realization, the top of the high-pressure airbag 2 is provided with an adjustment knob 3 that is screwed to the bag body 1. One end of the adjustment knob 3 is pressed against the high-pressure airbag 2. By rotating the adjustment knob 3, the strength of the adjustment knob 3 to squeeze the high-pressure airbag is different. The gas outlet speed and flow rate...

Embodiment 2

[0020] Such as image 3 , Figure 4 As shown, a pressurized and adjustable infusion bag includes a bag body 1, the bottom of the bag body 1 is connected to the infusion tube 11, and the top of the bag body 1 is provided with a high-pressure air bag 2 integrated with the bag body 1. The difference from the first embodiment is that In embodiment two, the bottom of the high-pressure air bag 2 is provided with an air outlet pipe 21, and a screw 5 is screwed on the top of the high-pressure air bag 2, and a sealing ring 51 is provided at the screw connection between the screw rod 5 and the high-pressure air bag 2 to prevent gas leakage. The front end is tapered and connected with the tail of the air outlet pipe 21, and the tapered portion of the air outlet pipe 21 can adopt a specification with an inner diameter of 2 mm to 5 mm, especially a specification of 2 mm to 3 mm. The outer periphery of the screw rod 5 is marked with a scale. By observing the change of the scale on the scre...

Abstract

The invention discloses a pressurization adjusting transfusion bag, which comprises a bag body. The bottom of the bag body is connected with a transfusion tube, an air pressure adjusting mechanism which is communicated with the inside of the bag body and is structurally integrated with the bag body is disposed at the top of the bag body, the air pressure adjusting mechanism and the bag body are designed integrally, so that manufacturing cost is lowered, operation is more convenient, and practicality is high. The air pressure adjusting mechanism is powered by a high-pressure air sac, the transfusion bag is powered by the aid of pressurization of the high-pressure air sac, pollution of liquid medicine due to the fact that the liquid medicine directly contacts with air is avoided, hanging transfusion is omitted, power of high-pressure transfusion is enough, flow of gas can be accurately controlled, and accordingly, the speed of liquid flowing into a human body can be accurately controlled.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a pressurized and regulated transfusion bag. Background technique [0002] At present, the known medical infusion set is suspended on the support by the infusion bag or the infusion bottle, and the air inlet needle is connected to the air inlet pipe. Under normal pressure, the gravity of the liquid is used as the power to make the air enter the infusion bottle from the air inlet pipe and the air inlet needle to generate air bubbles. Penetrate the liquid out of the liquid surface, gather in the space between the liquid surface and the bottom of the bottle to generate air pressure, and output it from the infusion needle. However, such a structure is powered by the gravity of the liquid, while using atmospheric pressure, its power is small; due to the need to hang the infusion bag high, the patient's activities need to be strictly restricted; in the medicine bottle, due to the need...
