The utility model is characterized in that a liquid discharge hole is positioned at the bottom of the medical solution memory; an end cover provided with a liquid inlet is fixed connected with the top part; the float with hollow structure has a disc shape; a convex body is positioned in the center of one side of the float; the convex body and the liquid discharge hole can be inserted into each other, forming a sealing space. The automatic closing buret type transfusion apparatus has the advantages of simple design due to that the float has an integrated structure without other fittings, and good sealing performance and high safety due to that the center of the side of the float where the convex body is positioned is a convex spherical surface, tightly attached to the liquid discharge hole; in addition, the float is green; as a result, the medical solution volume can be measured more easily according to the height of the float; the attention of the patients especially children is more likely to be distracted in order to relax the emotion.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of titration tubular type transfusion device that can close automatically.
Background technology
Utilize the transfusion system transfusion quite general in clinical practice.During use, insert the bottle cap of wearing infusion bottle with the perforator on the transfusion system tube for transfusion, when infusion bottle is inverted, medicinal liquid under the action of gravity in the infusion bottle tube for transfusion of flowing through splashes into the patient vessel, after transfusion is finished, if transfusion device also fails in time to close, can cause air admission blood vessel or blood to reflux, bring hidden danger for patient's life security.Existing infusion bottle is applicable to the adult, the child especially required amount of liquid medicine of baby lacks a lot than the adult, the medicinal liquid of can not failing Wan in the infusion bottle can only be dropped, produce waste, and the child especially baby's medicinal liquid input is many slightly will have influence on life security, whether the baby is totally lost to infuse at basic not consciousness, especially night to the infusion bottle herb liquid is more prone to have an accident.
For fear of the problems referred to above, people wish to infuse and can close automatically, thereby invented the multiple titration tubular type transfusion device that can close automatically, as application number is that the Chinese patent literature of 200410071728.X discloses automatic controller in a kind of medical Transfusion device, it comprises the medicinal liquid bottle, automatic controller and be located at glass georama float in the automatic controller, the plastic material of Magnet, the rustless metal pipe, the rustless metal sheet, rubber sleeve and the tube for transfusion that is communicated with automatic controller wait closes transfusion automatically, this project organization complexity, accessory in the automatic controller is many and cost is high; An accessory lost efficacy, and caused entire controller to lose efficacy, and the rustless metal pipe frequently contacts with the tube for transfusion that plastics are made, easily tube for transfusion is punctured, and poor durability, safety is low; And its feed liquor amount estimates that by the range estimation experience degree of accuracy of amount of infusion is not high, has relatively high expectations with child especially baby's amount of liquid medicine degree of accuracy relatively, otherwise can have influence on life security, so be not suitable for child's use.
Summary of the invention
The purpose of this utility model be low at the existing existing complex structure of titration tubular type transfusion device, the safety degree of accuracy low, amount of infusion that can close automatically, be not suitable for the child and use, a kind of degree of accuracy simple in structure, safe, amount of infusion the titration tubular type transfusion device that can close automatically that higher, suitable child uses is provided.
The purpose of this utility model can realize by following technical proposal: a kind of titration tubular type transfusion device that can close automatically, comprise medicinal liquid memorizer that is provided with the containing mark line and the float that is located at the medicinal liquid memory inside, described medicinal liquid memorizer bottom is provided with liquid outlet, the top is connected and is provided with the end cap of inlet, it is characterized in that, described float is in the form of annular discs and be hollow-core construction, and the center of described float one side is provided with a convex body that can plug with liquid outlet and form sealing.
When this utility model uses, at first according to the required dose of patient, medicinal liquid is added the medicinal liquid memorizer, this moment, float was floated, and the dose of adding can be measured by the pairing containing mark line of buoys float height, during transfusion, float descends with the minimizing of medicinal liquid, convex body grafting liquid in-out mouth, side that float contacts with liquid outlet and liquid outlet form sealing, and transfusion can be closed automatically.
In the above-mentioned a kind of titration tubular type transfusion device that can close automatically, described float two middle side parts are the spherical crown shape of evagination.Float descends with the minimizing of output medicinal liquid, and final convex body grafting liquid in-out mouth, land portions in the spherical crown shape structure of evagination and liquid outlet can fit tightly and make float and liquid outlet sealing.
In the above-mentioned a kind of titration tubular type transfusion device that can close automatically, described float opposite side center also is provided with and can plugs with liquid outlet and form the convex body of sealing.Float can be in the medicinal liquid memorizer arbitrary overturn.
In the above-mentioned a kind of titration tubular type transfusion device that can close automatically, described convex body is coniform, and its link is thicker.This structure convex body small end inserts liquid outlet earlier, and its rear end major part is inserted gradually then, and then the formation conical surface seals gradually.
