Abstract
Disclosed is an infusion device with a levitated sphere. The infusion device with the levitated sphere comprises infusion pipes, an anti-blocking mesh, a drip chamber and the levitated sphere. The two ends of the drip chamber are connected with the infusion pipes, the anti-blocking mesh and the levitated sphere are arranged in the drip chamber, the anti-blocking mesh is fixedly connected to the top of the drip chamber, and the levitated sphere floats up and down inside the drip chamber. Through the anti-blocking mesh and the levitated sphere which are arranged inside the drip chamber, the medical accidents that gas enters veins and blood backflow happens are avoided, and the opening of the infusion pipe on the upper portion of the drip chamber is prevented from being blocked by the levitated sphere.
Description
Technical background
The present invention relates to transfusion device, particularly a kind of transfusion device with the suspension ball.
Background technology
Transfusion device is very common medical apparatus and instruments, is mainly used in setting up the medicine liquid channel between medical containers such as infusion bottle or transfusion bag and the vein.
Existing transfusion device in use, need whether carry by the manual observation medicinal liquid and finish, in time to notify the nursing staff to change dressings, pull out operations such as pin, do not find in time that the medicinal liquid conveying finishes, and is very easy to cause gas to enter malpracticees such as vein, blood backflow if the patient is sleeping in the infusion process.
The transfusion device of the patent No. 200810014517.0 comprises 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 is arranged, and the ball float radius is greater than the tube for transfusion radius.Weak point is: can't guarantee that ball float can both drop on the 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, was the line contact, cutout effect instability.
Summary of the invention
At the deficiency described in the background technology, the invention provides a kind of transfusion device with the suspension ball can avoid gas to enter malpracticees such as vein, blood backflow in the medicinal liquid conveying when finishing.Avoid gas to enter malpracticees such as vein, blood backflow when finishing in order to realize that transfusion device can be carried at medicinal liquid, concrete technical scheme is as follows:
A kind of transfusion device with the suspension ball comprises 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 the 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-network blocking (2) bottom and side.
The density of described suspension ball is less than the density of medicinal liquid, and described suspension bulb diameter is less than the diameter of dropping funnel, greater than the diameter of tube for transfusion.
The bottom of described dropping funnel by taper surface and arc surface shape in conjunction with forming, taper surface is around the dropping funnel bottom, arc surface is in the centre, the arc surface outside is connected with taper surface 7, porose in the middle of the arc surface, the 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 malpracticees such as vein, blood backflow; (2) the 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, the suspension ball can not blocked the tube for transfusion on top; (4) the suspension ball is that face contacts with the dropping funnel bottom, the cutout effect stability.
Description of drawings
Fig. 1 is the structural representation of transfusion device.
Fig. 2 is the left view of anti-network blocking.
Fig. 3 is the vertical view of anti-network blocking.
Wherein, 1 is that tube for transfusion, 2 is medicinal liquid, 6 taper surfaces for the dropping funnel bottom, 7 arc surfaces for the dropping funnel bottom for suspension ball, 5 for dropping funnel, 4 for anti-network blocking, 3.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
A kind of transfusion device with the suspension ball comprises 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 about in the of 3, anti-network blocking 2 and suspension ball 4 are in dropping funnel 3, and anti-network blocking 2 is fixedlyed connected with dropping funnel 3, and suspension ball 4 can fluctuate in dropping funnel 3, for suspension ball 4 can be floated on the medicinal liquid 5, the density of suspension ball 4 is less than the density of medicinal liquid 5; The diameter of suspension ball 4 is less than the diameter of dropping funnel 3 diameter greater than 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 expired, 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 preventing network blocking 2.
The bottom of dropping funnel 3 by taper surface 6 and arc surface 7 shapes in conjunction with forming, taper surface 6 is around dropping funnel 3 bottoms, arc surface 7 is in the centre, arc surface 7 outsides are connected with taper surface 7, porose in the middle of the arc surface 7, the 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 the arc surface 7.Arc surface radius and suspension ball 4 radiuses equate just can guarantee when not having 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 malpracticees such as vein, blood backflow, because suspension ball 4 is that face contacts with dropping funnel 3 bottoms, the cutout effect stability.
