Description

The tube for transfusion siren

Technical field

This utility model relates to warning devices, especially a kind of tube for transfusion siren.

Background technology

Common tube for transfusion comprises reservoir, slow liquid pipe, mozzle three parts at present, alarm device is not installed, occurring syringe needle in patient's infusion process does not easily penetrate vein and causes liquid to be obstructed and the liquid phenomenons such as blood back of being totally lost, must judge by patient and entourage's perusal, in time do not observe or judge when inaccurate easily accidents causedly, exist to be difficult for observing, consume one's strength, operate inconvenience, easy accidents caused drawback.

Summary of the invention

The purpose of this utility model is exactly that a kind of flexible operation, safe and reliable, the tube for transfusion siren of saving manpower will be provided.

The purpose of this utility model is achieved in that a kind of tube for transfusion siren, comprise power supply 1, voice box 2, lead 3, switch 4, power supply 1, voice box 2 and lead 3 all are packaged in the lid 5, switch 4 is installed in lid 5 surfaces, also comprise upper and lower contact 6,7, fly rod 8, float 9, float 9 is arranged on the liquid level of slow flow tube 10, and fly rod 8 one ends stretch between the upper and lower contact 6,7 in the lid 5, contact 11 is installed in the end, and the other end stretches in the slow flow tube 10 and is connected with float 9.

After adopting said structure, owing on the liquid level in slow flow tube float is installed, warning system is connected with float by fly rod, makes the flow velocity of liquid in the tube for transfusion, volume change be delivered to warning system by float with the liquid level variation; Again owing in the alarm lid upper and lower contact is set, fly rod one end is installed contact between upper and lower contact, the loop that constitutes when upper contact contacts with contact can not penetrate the situation that vein causes liquid to be obstructed to the snagging syringe needle and gives the alarm, the loop that constitutes when lower contact contacts with contact can give the alarm flexible operation, safe and reliable to the situation that liquid is totally lost.

Description of drawings

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 1 double as Figure of abstract.

The specific embodiment

Tube for transfusion siren shown in Figure 1, comprise power supply 1, voice box 2, lead 3, switch 4, power supply 1, voice box 2 and lead 3 all are packaged in the lid 5, switch 4 is installed in lid 5 surfaces, also comprise upper and lower contact 6,7, fly rod 8, float 9, float 9 is arranged on the liquid level of slow flow tube 10, and fly rod 8 one ends stretch between the upper and lower contact 6,7 in the lid 5, contact 11 is installed in the end, and the other end stretches in the slow flow tube 10 and is connected with float 9.

Open this siren switch 4 during use, when the dropped stitch situation occurring, because flow of liquid is gone into vein and is obstructed, liquid level rises in the slow flow tube 10, float 9 on the liquid level with on move, promote to move on the fly rod 8, stretch into to move with upper contact 6 on the fly rod 8 end contacts 11 in the lid 5 and contact, connected by the last loop that upper contact 6, contact 11, lead 3, switch 4, power supply 1, voice box 2 constitute, voice box 2 sends chimes of doom and reminds user; When liquid is totally lost, liquid level descends in the slow flow tube 10, float 9 moves down thereupon, fly rod 8 moves down thereupon, stretching into fly rod 8 end contacts 11 in the lid 5 moves down with lower contact 7 and contacts, connected by the following loop that lower contact, contact 11, lead 3, switch 4, power supply 1, voice box 2 constitute, voice box 2 sends chimes of doom and reminds user.Its flexible operation, safe and reliable has avoided accidents such as dropped stitch, blood back to take place.
