Embodiment 1

[0036]A double-stop liquid-stop self-venting safety dropping funnel, including a housing 1 and a floating body, the upper end of the housing 1 is provided with a liquid inlet 11, the bottom of the housing 1 is provided with a liquid outlet 12, and the floating body is located on the In the housing 1, the floating body includes an upper floating body 2 and a lower floating body 3 detachably connected with the upper floating body 2, the bottom of the lower floating body 3 is provided with a bottom membrane 4, and the lower floating body 3 includes a plug-in part, so The plug-in part includes a plug-in board 30 and a column 31 vertically arranged in the middle of the plug-in board 30, and a through hole is provided through the upright post 31 in the axial direction, and the through-hole includes a central hole 310 and a side hole 311. The upper floating body 2 includes a central shaft 20 , and the central shaft 20 is inserted into the central hole 310 to realize the connection bet...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the size of the side hole 311 gradually decreases from the central hole 310 to the outside until it is closed. On the hole 311, under the same surface tension of water, the tip structure reduces the effective spherical radius when the liquid medicine drop enters the side hole 311, and the additional pressure to be overcome will increase, making it difficult for the liquid medicine to enter the side hole 311 , play the role of waterproof and exhaust.

Embodiment 3

[0047] The difference between this embodiment and Embodiment 2 is that the lower end of the upper floating body 2 is configured as an outwardly convex arc structure, and a sealing ring 5 is arranged between the inner side of the upper floating body 2 and the column 31, and the sealing ring The diameter of 5 is greater than the distance between the bottom of the upper floating body 2 and the outside of the column 31, so that the sealing ring 5 can drop between the upper floating body 2 and the lower floating body 3 to seal the gap.

[0048] The side wall of the column 31 is provided with a thin groove 10. When the liquid medicine is almost finished, the liquid medicine in the drip funnel gradually decreases. When the liquid medicine outside the floating body is lower than the liquid level in the cavity of the floating body, The liquid medicine in the cavity of the floating body can flow down slowly along the fine grooves 10, and the speed of flowing out of the liquid medicine in...

Abstract

The invention discloses a double-liquid-stopping self-air-discharging safe drip chamber, and solves the problems that an existing planar membrane easily deforms and moves in assembling, sterilizing and using processes, and the liquid stopping effect of the drip chamber is affected. The double-liquid-stopping self-air-discharging safe drip chamber comprises a shell and a floating body, wherein a liquid inlet is formed in the upper end of the shell; a liquid outlet is formed in the bottom of the shell; the floating body is positioned in the shell and comprises an upper floating body and a lowerfloating body which is detachably connected with the upper floating body; a bottom membrane is arranged on the bottom of the lower floating body; the lower floating body comprises an inserting portion; the inserting portion comprises an inserting plate and a stand column which is perpendicularly arranged in the middle of the inserting plate; a through hole is formed in the stand column in the axial direction in a penetrating manner; the through hole comprises a central hole and a side hole; the upper floating body comprises a central shaft; and the central shaft is inserted in the central hole. The double-liquid-stopping self-air-discharging safe drip chamber has the advantages that the sealing property of the bottom membrane is good, the liquid stopping effect of the drip chamber is goodand the like.

Description

technical field [0001] The invention relates to the technical field of infusion sets, in particular to a double-stop liquid-stop self-exhaust safety drip funnel. Background technique [0002] The drip funnel is one of the key components of the infusion set. Through the drip funnel, you can observe the speed of the liquid medicine output, and you can also judge whether it is blocked, whether the liquid medicine has been infused, and other important information, which is of great significance to ensure the safety of the infusion patients. [0003] But even if there is a dripping funnel, it is inevitable that due to negligence, the situation of the medicinal liquid in the dripping funnel cannot be noticed in time. When the medicinal liquid is infused, if the needle is not pulled out in time, it will enter the air. Entering blood vessels may cause embolism, and may even cause death in severe cases. Therefore, setting up a drip funnel that can stop the liquid is of great signific...
