Embodiment 1

[0035] Embodiment one: as attached figure 1 As shown, the buoyancy type non-return infusion device includes a non-return housing 1 and a float 2. The non-return housing 1 is respectively provided with a liquid inlet channel 3 and a liquid storage chamber 4. The upper part of the liquid inlet channel 3 is located in the non-return housing. The liquid inlet on the body 1, a communication channel 5 is provided between the liquid inlet channel 3 and the liquid storage chamber 4, and the bottom of the liquid storage chamber 4 is provided with a liquid outlet 6, corresponding to the liquid storage chamber 4 above the liquid outlet 6 The inner sleeve is equipped with a float 2 that can float up when the liquid level of the liquid medicine exceeds the minimum limit and fall and block the liquid outlet 6 when the liquid level of the liquid medicine is lower than the minimum limit, corresponding to the non-return housing 1 at the upper part of the liquid storage chamber 4 A one-way l...

Embodiment 2

[0038] Embodiment two: as attached figure 2 As shown, a normally open magnetic reed switch that can be closed when the float 2 floats and disconnected when it sinks is provided on the upper outer side of the non-return housing 1 . According to requirements, the normally open magnetic reed switch can be installed on the non-return housing 1 by pasting, absorbing, fixing, etc., and when the float 2 floats up, it is within the effective sensing range of the normally open magnetic reed switch. When sinking, it is outside the effective sensing range of the normally open reed switch; during use, when the float 2 floats up, the normally open reed switch is closed, the circuit where it is located is connected, and the wireless signal transmitting device 20 enters the use state and activates The start-up procedure of the wireless signal receiving alarm device, and at the same time send a normal wireless signal to the wireless signal receiving alarm device; The type reed switch will...

Embodiment 3

[0040] Embodiment three: as attached image 3 As shown, there is an installation groove 17 on the top of the non-return housing 1, and a normally open magnetic reed switch that can be closed when the float 2 floats and disconnected when it sinks is provided in the installation groove 17.

Abstract

The invention relates to the technical field of medical liquid parts and provides a buoyancy type non-returning transfusion device. The buoyancy type non-returning transfusion device comprises a non-returning shell and a floater, wherein a liquid inlet channel and a liquid storage cavity are arranged in the non-returning shell; the upper part of the liquid inlet channel is provided with a liquid inlet formed in the non-returning shell; a communication channel is arranged between the liquid inlet channel and the liquid storage cavity; a liquid outlet is formed in the bottom of the liquid storage cavity; the floater, which can float up when the liquid level height of medicine liquid exceeds the lowest limitation and block the liquid outlet when the liquid level height of the medicine liquid is lower than the lowest limitation, is arranged in the liquid storage cavity above the liquid outlet in a sleeving manner. According to the buoyancy type non-returning transfusion device, the liquid inlet channel and the liquid storage cavity are separately arranged and the acting force on the floater by liquid drops can be effectively eliminated; the restriction of a liquid dropping to a gap between the floater and the liquid storage cavity, and a medicine liquid dropping flow channel and the flow speed can also be effectively eliminated; the non-returning effect is good and the manpower is freed; patients or accompanying people do not need to observe liquid dropping conditions all the time; the adaptability of adopting the buoyancy to control the rising and falling of the floater is strong, the utilization requirements of a plurality of types of medicine liquid can be met and the popularization is convenient.

Description

technical field [0001] The invention relates to the technical field of medical liquid fittings, and relates to a buoyancy type non-return transfusion device. Background technique [0002] Currently commonly used infusion sets generally include intravenous needles, protective caps, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, cork puncturers and air intake pipe air filters, etc., all of which require patients or escorts during use. People observe the dripping process, and when the liquid is about to run out, replace it with a new liquid or pull out the venous needle, so as to prevent the phenomenon of blood backflow after the liquid is dripped out. However, the dripping process is long and boring, and patients or guardians are easily distracted or sleepy during the observation process, so that the phenomenon of blood returning occurs from time to time, and cannot be better resolved. [0003] In the prior art, there are also devices that can preve...
