Abstract
The utility model relates to a safe transfusion device which can prevent exhaustion of transfusing liquid and backflow of blood. The device comprises a shell, an upper cylinder and a lower cylinder which are fixed in the shell by cylinder bottom. Mouth of the upper cylinder is opposite to that of the lower cylinder, and the other cylinder mouth is respectively provided an openable cover; wherein, the upper cover is connected with a floating ball. During the transfusing of the liquid in the upper cylinder rises, the floating ball draws and opens the upper cover, so the transfusing liquid flows from the upper cylinder to the lower cylinder. When the transfusing liquid uses out, the floating ball with no buoyancy seals the upper cover and stop transfusion. When the blood flows back, the lower cover is to seal port of the lower cylinder under backflow force so to prevent continuous flowing of the blood. The utility model has the advantages of simple structure, convenient use, strong security and reliability, and is suitable for being used in company with disposable transference.
Description
Technical field
This utility model relates to a kind of and the matching used safe transfusion device of transfusion device, prevents that particularly device empty and that blood refluxes is dripped in transfusion in the infusion process.
Background technology
In the clinical transfusion process, following two kinds of phenomenons often occur at present: a kind of is that transfusion is also being carried out when sky is dripped in transfusion, causes the air input easily; Another kind is that the blood backflow phenomenon is arranged when transfusion.These two kinds of phenomenons cause serious psychological burden but for patient and medical worker and family numbers of patients, make him see whole infusion process carefully, can not loosen rest.And that some infusion sets on the existing market can only prevent is above wherein a kind of, can not prevent this two kinds of phenomenons simultaneously, and the processing technique difficulty is big, cost is high.
The utility model technical scheme
The purpose of this utility model be to provide a kind of and transfusion device matching used, both had transfusion and drip and can close transfusion rapidly automatically when empty, have the safe transfusion device that prevents that blood from refluxing again, and simple in structure, easy to process.
The technical solution of the utility model is achieved in that it comprises by having the upper casing that feed liquor chews and having the housing that lower casing that fluid chews constitutes, use top cylinder and the doffing of cylinder base sealing and fixing in housing upper casing and lower casing respectively, and make top cylinder relative with the nozzle of doffing; But the other end nozzle of top cylinder and doffing is respectively equipped with the capping of opening and closing, wherein also is connected with ball float on the upper cover.When unused state, top cylinder is under the effect of ball float gravity, and the upper cover involution is on top cylinder, and following capping is in the state of parting a little open.During supporting use, feed liquor is chewed to chew respectively with fluid and is pegged graft with the transfusion device flexible pipe.When the medicinal liquid in the top cylinder rose, ball float produced buoyancy and spurs upper cover on the top cylinder, and it is opened, and medicinal liquid is in top cylinder flows into doffing, and the following of doffing is sealed under the liquid gravity effect, opens fully, and medicinal liquid is chewed outflow from dehiscing through the doffing fluid again.Defeated empty when medicinal liquid, when the medicinal liquid face in the top cylinder was brought down below ball float, ball float did not have buoyancy, and under the action of gravity of self, the upper cover lid was closed on the top cylinder nozzle, and transfusion is stopped automatically; When blood refluxed, doffing following was sealed under the effect of backflow power, with doffing port involution, thereby prevented that blood from further refluxing, and reached the safe and reliable purpose of transfusion.
Obviously, the utlity model has simple in structurely, easy to use, advantage such as security reliability is strong is particularly suitable for the supporting use on the disposable transfusion device.
Below in conjunction with embodiment shown in the drawings, this utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure: 1. cylindrical shell, the 1a. upper casing, the 1b. lower casing, 2. ball float, 3. top cylinder, the 3a. upper cover, 4. cylinder base, 5. doffing, capping under the 5a., 6. feed liquor is chewed, and 7. fluid is chewed.
The specific embodiment
Referring to Fig. 1, safe transfusion device comprises by upper casing 1a and lower casing 1b and plugs together the housing 1 that constitutes, be contained in top cylinder 3 and doffing 5 in upper casing 1a and the lower casing 1b respectively with cylinder base 4, top cylinder 3 is relative with doffing 5 nozzles, has upper cover 3a and following capping 5a on its another port respectively; Be connected with ball float 2 on the upper cover 3a, upper casing 1a top is provided with feed liquor and chews 6, and cylindrical shell 4 constitutes an admission chamber with upper casing 1a; Lower casing 1b bottom is provided with fluid and chews 7, and cylinder base 4 constitutes one with lower casing 1b and goes out sap cavity, admission chamber with go out sap cavity by cylinder base 4 packings, have only by top cylinder 3 and doffing 5 and flow.Top cylinder 3, upper cover 3a and doffing 5, following capping 5a all adopt elastomeric material, and make them make one, one-sided switching.Like this, as long as fill medicinal liquid in the admission chamber, and liquid level is when touching ball float, and upper cover 3a opens, and medicinal liquid flows into top cylinder 3, enters doffing 5 again, and under the effect of medicinal liquid gravity, opens down capping, enters out sap cavity, chews 7 by fluid and exports.When the medicinal liquid in the admission chamber was lower than ball float, top cylinder was closed, and loading stops; When blood refluxes, the blood that goes out in the liquid air will descend capping 5a involution on lower shell 5 ends, stop the backflow of blood, make transfusion safe and reliable, thereby can effectively remove patient, family members, medical worker's psychological burden.
Claims (3)
