Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a pressurizable puncture drip chamber. Background Art

[0002] The puncture dripper is used in conjunction with a disposable intravenous infusion needle and is mainly used for clinical gravity infusion. Under the action of atmospheric pressure, the liquid in the bottle flows into the dripper along a thin infusion hose. When the water column pressure in the dripper is greater than the venous pressure, the liquid in the bottle flows into the vein along the hose. However, during the infusion of the current puncture dripper, the pressure in the bottle decreases during the dripping process, causing the liquid to not fall down, and even causing blood backflow. The continuous backflow of blood causes panic in patients, and the backflow blood coagulation causes harm to patients. Summary of the invention

[0003] In order to solve the problems of the prior art, the present invention provides a pressurized puncture dripping funnel which can increase the pressure in the bottle and solve the problem of blood backflow.

[0005] As a preferred solution, the metal tube is vertically arranged, and the length of the metal tube is greater than the length of the bottle stopper piercer.

[0006] As a preferred solution, the bypass channel is arranged at an angle.

[0007] As a preferred embodiment, the liquid passage is connected to an opening on the bottle stopper piercer.

[0017] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0018] like Figures 1 to 3 As shown, a pressurized puncture dropper in this embodiment includes a bottle stopper puncture device 1, a ball 2, a pressurizing joint 3, a liquid passage 4, a dropper 5, a dropper 6 and a metal tube 7. The bottle stopper puncture device 1 is arranged above the dropper 6, the bottle stopper puncture device 1 is connected to the dropper 6, the bottle stopper puncture device 1 is connected to the dropper 6, and the dropper 5 has a liquid passage 4. The pressurizing joint 3 is connected to the bottle stopper puncture device 1, and the bottle stopper puncture device 1 is provided with a bypass channel 11, and the bypass channel 11 is provided with a ball 2. The pressurizing joint 3 is connected to the bypass channel 11, and the metal tube 7 is penetrated in the bottle stopper puncture device 1 and is connected with the bypass channel 11. In the above technical scheme, the bottle stopper puncture device 1 can puncture the bottle stopper of the medicine bottle, and the medicine enters the dropper 6 through the liquid passage 4 of the dropper 5. The pressurizing joint 3 is connected to the gas source, and the gas source can be a gas supply device. Gas is injected from the pressurized joint 3, and the gas passes through the metal tube 7 and enters the bottom of the medicine bottle. The pressure in the medicine bottle increases, and the liquid flows from the liquid passage 4 to the dripping funnel 6. After pressurization, the ball 2 just blocks the pressurized joint 3 under the pressure in the bottle to prevent the liquid from flowing back and ensure the pressure in the bottle. Through the above technical scheme, compared with the common puncture dripping funnel, the pressurized puncture dripping funnel of this embodiment can be pressurized and does not flow back, which effectively solves the problem of continuous backflow of blood causing panic in patients and the problem of backflow blood coagulation causing harm to patients, and ensures the pressure in the bottle.

[0019] In this embodiment, the metal tube 7 is arranged vertically, and the length of the metal tube 7 is greater than the length of the bottle stopper piercer 1, so that the metal tube can be inserted into the bottom of the medicine bottle. The pressurized joint 3 of this embodiment is bonded to the bottle stopper piercer 1, and the bottle stopper piercer 1 is bonded to the drip chamber 6, so as to facilitate the connection. The bypass channel 11 is arranged obliquely, so that the ball 2 can roll in the bypass channel 11. The liquid passage 4 is connected to the opening 12 on the bottle stopper piercer 1, and the liquid medicine in the bottle enters the liquid passage 4 through the opening 12.

[0020] A pressurized puncture drip chamber in this embodiment can increase the pressure in the bottle, and can prevent blood from flowing back when the patient injects drugs intravenously, effectively solving the problem of panic caused by continuous backflow of blood and harm to the patient caused by coagulation of backflow blood.
