Abstract
The invention discloses an infusion apparatus with a density suspension block and relates to the field of infusion apparatuses. The infusion apparatus comprises an infusion tube, an anti-blocking net, a drip chamber and a suspension block, wherein the upper and lower ends of the drip chamber are connected with the infusion tube; the anti-blocking net and the suspension block are arranged in the drip chamber; the anti-blocking net is fixedly connected to the top of the drip chamber; and the suspension block can vertically float in the drip chamber. By using the infusion apparatus, medical negligence including the injection of air into the vein and blood backflow can be prevented, and the suspension block is prevented from blocking an infusion tube opening on the upper part of the drip chamber.
Description
Technical background
The present invention relates to transfusion device, particularly a kind of transfusion device that has density suspension piece.
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 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, technical scheme is as follows.
A kind of transfusion device with density suspension piece, comprise tube for transfusion (1), anti-network blocking (2), dropping funnel (3) and suspension piece (4), dropping funnel (3) two ends up and down connects tube for transfusion (1), anti-network blocking (2) and suspension piece (4) are in dropping funnel (3), anti-network blocking (2) is fixedly connected on dropping funnel (3) top, and suspension piece (4) can fluctuate in dropping funnel (3).
Described anti-network blocking (2) is arranged on dropping funnel (3) import department, and anti-network blocking (2) is fixedly connected on the top of dropping funnel (3), and there is mesh anti-network blocking (2) bottom and side.
The global density of described suspension piece (4) is less than the density of medicinal liquid (5).
Described suspension piece (4) is an integral body, suspension piece (4) top is cylindrical piece, the bottom is circular cone (6), and the big face diameter of circular cone (6) equates with body diameter, and the body diameter of suspension piece (4) is less than the diameter of dropping funnel (3) diameter greater than tube for transfusion (1).
Described suspension piece (4) is divided into (6) two different parts of density of cylindrical piece and circular cone, and the density of circular cone (6) part is greater than the density of cylindrical piece part.
The bottom of described dropping funnel (3) has taper surface (7) to constitute, and porose in the middle of the taper surface, the radius in hole is identical with the radius of tube for transfusion, and the hole is connected with tube for transfusion, and circular cone (6) tapering of its tapering and suspension piece (4) bottom is identical.
Beneficial effect is that (1) prevents that gas from entering malpracticees such as vein, blood backflow; (2) the suspension piece falls all at every turn and can drop on the tube for transfusion; (3) anti-network blocking is arranged at dropping funnel top, and when medicinal liquid was filled dropping funnel, the suspension piece can not blocked the tube for transfusion on top; (4) the suspension piece 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 that anti-network blocking, 3 is that dropping funnel, 4 is that suspension piece, 5 is that medicinal liquid, 6 is that the circular cone of suspension piece, 7 is the taper 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 the suspension piece comprises tube for transfusion 1, anti-network blocking 2, dropping funnel 3 and suspension piece 4.Dropping funnel connects tube for transfusion 1 in two ends about in the of 3, anti-network blocking 2 and suspension piece 4 are in dropping funnel 3, and anti-network blocking 2 is fixedly connected on dropping funnel 3 tops, and suspension piece 4 can fluctuate in dropping funnel 3, for suspension piece 4 can be floated on the medicinal liquid 5, the density of suspension piece 4 is less than the density of medicinal liquid 5; The diameter of suspension piece 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 piece 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 piece 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.
For suspension piece 4 can be floated on the medicinal liquid 5, the global density of suspension piece 4 is less than the density of medicinal liquid 5; Suspension piece 4 is an integral body, suspension piece 4 tops are cylindrical pieces, the bottom is circular cone, the big face diameter of circular cone and body diameter equate, the body diameter of suspension piece 4 is less than the diameter of dropping funnel 3 diameter greater than tube for transfusion 1, for make suspension piece 4 be all the time the bottom downwards, suspension piece 4 is divided into cylindrical and two different parts of density of taper, cylindrical part is top, tapering part is the bottom, the density of tapering part is greater than the density of cylindrical part, and when guaranteeing like this in the dropping funnel medicinal liquid 5 to be arranged, the circular cone of suspension piece 4 is that the bottom is downward all the time.
The bottom of dropping funnel 3 has taper surface 7 to constitute, porose in the middle of the taper surface, the radius in hole is identical with the radius of tube for transfusion, the hole is connected with tube for transfusion, and its tapering is identical with the taper tapering of suspension piece 4 bottoms, so just can guarantee when not having medicinal liquid, suspension piece 4 fall can with dropping funnel 3 automatic cut out that fits together reliably, prevent that gas from entering malpracticees such as vein, blood backflow, because suspension piece 4 is that face contacts with dropping funnel 3 bottoms, the cutout effect stability.
