Abstract
The utility model provides an infusion device with a suspension ball. The infusion device comprises an infusion tube, an anti-blocking net, a dripping bucket and the suspension ball, wherein the two ends of the dripping bucket are connected with the infusion tube; the anti-blocking net and the suspension ball are arranged in the dripping bucket; the anti-blocking net is fixedly connected with the top of the dripping bucket; the suspension ball floats up and down in the dripping bucket; the dripping bucket is internally provided with the anti-blocking net and the suspension ball so as to prevent medical accidents that gas enters veins, blood flows back and the like, and prevent the suspension ball from blocking an infusion tube opening on the upper part of the dripping bucket.
Description
Technical field
The present invention relates to transfusion device, particularly a kind of transfusion device with suspension ball.
Background technology
Transfusion device is very common medical apparatus and instruments, is mainly used in setting up the medicine liquid channel between the medical containers such as infusion bottle or transfusion bag and vein.
Existing transfusion device in use, need to whether carry complete by the manual observation medicinal liquid, to notify in time the nursing staff to change dressings, pull out the operations such as pin, if in infusion process, the patient is sleeping, do not find in time that the medicinal liquid conveying is complete, be very easy to cause gas to enter the malpracticees such as vein, blood backflow.
The transfusion device of the patent No. 200810014517.0, comprise tube for transfusion, dropping funnel, and the tube for transfusion cavity is identical with the dropping funnel cavity, in the dropping funnel cavity, ball float arranged, and the ball float radius is greater than the tube for transfusion radius.Weak point is: can't guarantee that ball float can drop on tube for transfusion each time; When medicinal liquid was filled dropping funnel, ball float can be blocked the tube for transfusion on top; When ball float was blocked tube for transfusion, the contact surface of ball float and dropping funnel bottom was a circle, is the line contact, and the cutout effect is unstable.
Summary of the invention
For the deficiency described in background technology, the invention provides a kind of transfusion device with suspension ball can carry when complete and avoid gas to enter the malpracticees such as vein, blood backflow at medicinal liquid.In order to realize that transfusion device can carry when complete and avoid gas to enter the malpracticees such as vein, blood backflow at medicinal liquid, concrete technical scheme is as follows:
A kind of transfusion device with suspension ball, comprise tube for transfusion, anti-network blocking, dropping funnel and suspension ball, and the dropping funnel two ends connect tube for transfusion, and anti-network blocking and suspension ball are in dropping funnel, and anti-network blocking is fixedly connected on the dropping funnel top, and suspension ball can fluctuate in dropping funnel.
Described anti-network blocking is arranged on dropping funnel import department, and anti-network blocking and dropping funnel top are fixed together, and there is mesh anti-blocking sieve bottom and side.
The density of described suspension ball is less than the density of medicinal liquid, and described suspension ball diameter is less than the diameter of dropping funnel, is greater than the diameter of tube for transfusion.
The bottom of described dropping funnel by taper surface and arc surface in conjunction with forming, taper surface is in dropping funnel bottom surrounding, arc surface is in centre, the arc surface outside is connected with taper surface, porose in the middle of arc surface, hole is connected with tube for transfusion, and the radius in hole is identical with the tube for transfusion inside radius, and the arc surface radius is greater than suspension ball 4 radius 0.1-0.5 millimeters.
Beneficial effect is: (1) prevents that gas from entering the malpracticees such as vein, blood backflow; (2) suspension ball falls on the cambered surface that all can drop on dropping funnel bottom circle at every turn; (3) anti-network blocking is arranged at dropping funnel top, and when medicinal liquid was filled dropping funnel, suspension ball can not blocked the tube for transfusion on top; (4) suspension ball is that face contacts with the dropping funnel bottom, the cutout effect stability.
The accompanying drawing explanation
Fig. 1 is the structural representation of transfusion device.
Fig. 2 is the left view of anti-network blocking.
Fig. 3 is the top view of anti-network blocking.
Wherein, 1 is that tube for transfusion, 2 is that anti-network blocking, 3 is that the taper surfaces, 7 that dropping funnel, 4 is the dropping funnel bottom for suspension ball, 5 for medicinal liquid, 6 are the arc surfaces of dropping funnel bottom.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
A kind of transfusion device with suspension ball, comprise tube for transfusion 1, anti-network blocking 2, dropping funnel 3 and suspension ball 4.Dropping funnel connects tube for transfusion 1 in two ends Shang Xia 3, anti-network blocking 2 and suspension ball 4 are in dropping funnel 3, and anti-network blocking 2 is fixedly connected with dropping funnel 3, and suspension ball 4 can fluctuate in dropping funnel 3, for suspension ball 4 can be floated on medicinal liquid 5, the density of suspension ball 4 is less than the density of medicinal liquid 5; The diameter that the diameter of suspension ball 4 is less than dropping funnel 3 is greater than the diameter of tube for transfusion 1.
When preventing that dropping funnel 3 herb liquids 5 are full, suspension ball 4 is blocked the import of tube for transfusion 1, in import department, an anti-network blocking 2 is set, anti-network blocking 2 links together with dropping funnel 3 tops, there is mesh anti-network blocking 2 bottoms and side, when dropping funnel 3 herb liquids 5 were full, suspension ball 4 can be blocked by bottom or the side of anti-network blocking 2, and medicinal liquid 5 can splash into dropping funnel 3 from its lap of anti-network blocking 2.
The bottom of dropping funnel 3 is formed by taper surface 6 and arc surface 7 combinations, taper surface 6 is in dropping funnel 3 bottom surroundings, arc surface 7 is in centre, arc surface 7 outsides are connected with taper surface 7, porose in the middle of arc surface 7, hole is connected with tube for transfusion, and the radius in hole is identical with the tube for transfusion inside radius, arc surface 7 radiuses are greater than suspension ball 4 radius 0.1-0.5 millimeters, so that suspension ball 4 is fallen in arc surface 7.Arc surface radius and suspension ball 4 radiuses equate just can guarantee when there is no medicinal liquid 5, suspension ball 4 falls the automatic cut out that can fit together reliably with the arc surface of dropping funnel 3 bottoms, prevent that gas from entering the malpracticees such as vein, blood backflow, because suspension ball 4 is that face contacts with dropping funnel 3 bottoms, the cutout effect stability.
