Abstract
The utility model discloses an infusion set drip kettle for preventing blood backflow in a vein, and relates to the field of medical apparatus. The infusion set drip kettle consists of a kettle body (1) and a floating block (3), wherein an inner wall of the kettle body (1) is provided with two vertical small slide rods (2) with smooth outer surfaces, and two ends of the small slide rods (2) are connected with the kettle body (1). The floating block (3) which is a column shell body is arranged inside the kettle body (1), an upper end face of the floating block is a plane, a lower end face of the floating block is matched with an inner surface of the lower end of the kettle body (1), two outer sides of the middle portion of the floating block (3) are respectively provided with a slide ring (4) corresponding to the small slide rods (2), and the small slide rods (2) are sleeved in the slide rings (4). The infusion set drip kettle for preventing blood backflow in the vein is simple in structure and easy to manufacture, overcomes the drawback of the blood backflow in the vein of a patient if a needle is not pulled out timely when infusion to the patient is finished, reduces troubles to medical workers, enables infusion treatment to the patient to be safer, and can be widely used in medical clinics.
Description
Technical field
This utility model relates to medical instruments field, and the transfusion device that relates in particular to a kind of anti-vein blood back that uses when the medical worker infuses to the patient drips kettle.
Background technology
Transfusion is that each medical institutions is the conventional means of patient treatment disease.Tube for transfusion is necessary the medical apparatus that transfusion is effectively implemented, and used tube for transfusion is by pricker, plastic tube, flow control switch, Fei Shi does not drip kettle, blowdown pipe, air filter and plug and constitutes, and medicinal liquid is through tube for transfusion entering patient's vein.But, do not have the reliable setting of anti-vein blood back on the used tube for transfusion; In the infusion process of reality, the medical worker is busy or forget sometimes, and the patient loses consciousness " deep sound sleep " again, and at this time the medicinal liquid no one that is totally lost finds, can not extract pricker in time, will cause patient's vein blood back, produces many inconvenience and problem.If technological improvement or innovation are carried out in certain position of tube for transfusion; And then after reaching transfusion and finishing, even the untimely pricker of extracting, the effect that patient's vein can blood back yet; Then both reduced and given medical personnel's trouble caused, made again that patient's infusion treatment was safer.
Summary of the invention
This utility model is to overcome the deficiency of prior art, can close automatically after providing a kind of transfusion to finish, and the untimely also blood back not of pricker vein of extracting is simple in structure, make easily, and the transfusion device that little amplitude increases a kind of anti-vein blood back of production cost drips kettle.
In order to reach above purpose, the technical scheme that this utility model is taked is: the transfusion device of this a kind of anti-vein blood back drips kettle and is made up of kettle body, floating block.It is characterized in that: the inwall of kettle body is provided with two little litter vertical, smooth outer surface, and the two ends of little litter are connected on the kettle body; The inside of kettle body is provided with a floating block, and floating block is a cylindrical shell, and its upper surface is the plane, and its lower surface is identical identical with the inner surface of kettle body lower end, and the external diameter of floating block is less than the internal diameter of kettle body, greater than the external diameter that goes out the medicinal liquid mouth.Can or glide along correct track come-up in order to limit floating block, respectively establish a slip ring corresponding with little litter in two outsides, middle part of floating block, little litter is enclosed within the inside of slip ring.
In addition, the kettle body advances the medicinal liquid mouth and goes out the medicinal liquid mouth and all be connected on the plastic tube.
When using this utility model, when medicinal liquid advances the kettle body, floating block is at medicinal liquid buoyancy function float downward; Go out the medicinal liquid mouth and open, medicinal liquid flows into patient's vein, after transfusion finishes; Floating block sinks under the effect of gravity; Be close to the lower end of kettle body, kettle body lower end closed can not reflux patient's vein blood.
The beneficial effect of this utility model is: this utility model is simple in structure, makes easily, has overcome present patient's transfusion and has finished, if untimelyly extract the drawback that pricker causes patient's vein blood back; Both reduced and given medical personnel's trouble caused, made again that patient's infusion treatment was safer; Can be widely used in hospital clinic.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model.
Accompanying drawing 2 is the A-A generalized section of this utility model.
The specific embodiment
With reference to accompanying drawing 1, accompanying drawing 2 class's of making utility models.The transfusion device of this a kind of anti-vein blood back drips kettle and is made up of kettle body 1, floating block 3, and the inwall of kettle body 1 is provided with two little litter 2 vertical, smooth outer surface, and the two ends of little litter 2 are connected on the kettle body 1; The inside of kettle body 1 is provided with a floating block 3, and floating block 3 is a cylindrical shell, and its upper surface is the plane, and its lower surface is identical identical with the inner surface of kettle body 1 lower end, and the external diameter of floating block 3 is less than the internal diameter of kettle body 1, greater than the external diameter that goes out medicinal liquid mouth 6; Respectively establish a slip ring 4 corresponding in two outsides, middle part of floating block 3, little litter 2 is enclosed within the inside of slip ring 4 with little litter 2.
In addition, kettle body 1 advances medicinal liquid mouth 5 and goes out medicinal liquid mouth 6 all to be connected on the plastic tube 7.
