Abstract
The invention provides a portable infusion set which is characterized by comprising a tube body, wherein both ends of the tube body are respectively provided with a tube cover and a needle stand, a piston is arranged in the cavity of the tube body, one end of a piston rod is fixed with the piston, the other end of the piston rod extends out of the tube cover, the piston rod and the tube cover form a clearance fit, an extension spring is arranged between the piston and the tube cover and sheathed on the piston rod, and the elastic force of the extension spring pushes the piston towards the needle stand. The portable infusion set has the functions of pushing liquor into human blood circulation and containing the liquor. By using the structure, the extension spring between the piston and the tube cover can always apply pressure onto the liquor in the tube cavity, so that the infusion set can be freely arranged horizontally; and even if the horizontal height of the infusion set is less than that of the infusion position of the patient, the liquor can still be infused into the human blood circulation under the action of the pressure of the extension spring. Therefore, the portable infusion set is more convenient to use and enhances the safety for infusion.
Description
Technical field
The present invention relates to medical apparatus and instruments, relate in particular to a kind of portable infusion device.
Background technology
Transfusion device is used for human vein is splashed into medicinal liquid, make medicinal liquid directly enter the blood of human body circulation, existing transfusion device is owing to need overcome certain pressure and prevent that the liquid-transport pipe-line of air by transfusion device from entering the blood of human body circulation and causing air embolism to jeopardize patient's life security, therefore the infusion bottle inversion that needs to be connected on the transfusion device is suspended from certain altitude, the level height that is higher than patient's transfusion part with the level height that guarantees infusion bottle, so that medicinal liquid keeps certain pressure, allow in the infusion bottle air be controlled at the top of medicinal liquid, on the one hand, prevent the circulation of air admission blood of human body, on the other hand, prevent that patient's body inner blood from flowing backwards in the transfusion device, enter the blood of human body circulation under pressure smoothly with the assurance medicinal liquid, thereby finish whole infusion treatment process safely and effectively.But, in use there is following shortcoming in existing transfusion device: at first, because transfusion device must be used with infusion bottle, medicinal liquid is contained in the infusion bottle, transfusion device itself only has the guiding medicinal liquid and enters blood of human body circulation function, so function singleness of transfusion device, use inconvenient, though having the guiding medicinal liquid simultaneously, the syringe in the present medical apparatus and instruments enters the function of human body and the function of receiving medical liquids, but syringe is generally used for intramuscular injection, amount of liquid medicine in the syringe is less, inject time is generally in one minute, medicinal liquid source pressure in the syringe is in the piston rod of the artificial pushing syringe of medical worker, but infuse normally intravenous drip, therefore the drop time can not be directly used in existing this syringe in the transfusion medical treatment generally in dozens of minutes.Secondly, because transfusion device must be used with infusion bottle, in infusion process, infusion bottle must keep vertical suspension, need the extra hanger bracket that increases, simultaneously, the level height of infusion bottle must be higher than the infuse level height of position of patient, therefore the patient can easily arbitrarily not move when transfusion, particularly in disaster first-aid transporting, transportation patient's process, the height and position and the vertical position that need keep infusion bottle when using existing transfusion device by extra staff use and inconvenient.
Summary of the invention
The technical problem that the present invention solves is: a kind of portable infusion device is provided, and the patient can realize transfusion easily in moving process.
Technical scheme of the present invention is: a kind of portable infusion device, it is characterized in that, comprise body, the two ends of body are respectively equipped with pipe lid and needle stand, are provided with piston in the tube chamber of body, one end and the described piston of one piston rod are fixed, the other end of piston rod stretches out described pipe lid, and matched in clearance between piston rod and the pipe lid, is provided with a coil tension spring between described piston and the described pipe lid, this coil tension spring is set on the described piston rod, and the elastic force of coil tension spring is pushed piston to the needle stand direction.Can inject medicinal liquid in the tube chamber of body, make the present invention not only have the medicinal liquid of promotion and enter blood of human body circulation function, the function that also has receiving medical liquids, and after adopting this structure, coil tension spring between piston and pipe lid can be exerted pressure to the medicinal liquid in the tube chamber all the time, transfusion device is horizontal positioned arbitrarily, even the level height of transfusion device is lower than the level height of patient's transfusion part, medicinal liquid also can be injected under the effect of coil tension spring pressure in the blood of human body circulation, therefore uses convenient, as to have improved transfusion safety.
In order to infuse, the control medicinal liquid enters the speed and the transfusion time of human body, and described needle stand is provided with flow control valve.
Body, needle stand and boss are formed in one.
For the ease of flow control valve is installed, described needle stand is provided with a boss, and described flow control valve is arranged on the boss of needle stand.
In order to control the input total amount of medicinal liquid, described piston rod is provided with limit pin hole, is inserted with spacing pin in the described limit pin hole, and when spacing pin moved and be attached to the outer face of pipe lid, piston rod stopped to move, thereby stops medicinal liquid to continue to be injected in the human body.
The medicinal liquid of annotating in the body tube chamber for convenience, described body is provided with the chemicals dosing plant that is used for toward the tube chamber filling medicinal liquid of body, this chemicals dosing plant comprises the cylindrical base that is fixed on the body lateral wall, the middle part of this cylindrical base is provided with the dosing hole, this dosing hole is communicated with the tube chamber of body, dosing is provided with rubber seal plug in the hole, and the end of cylindrical base is provided with end cap, and described rubber seal plug hides in described end cap.
For piston can be pushed into the medicinal liquid in the body tube chamber in the human body fully, the length of described coil tension spring is more than or equal to the length of described body.
In order to show clearly that medicinal liquid injects the dosage of human body, is equipped with the volume scale marker on the lateral wall of described body, the described piston rod.
By hose connection infusion needle arranged on the described needle stand.
The invention has the beneficial effects as follows: the present invention has the function that the promotion medicinal liquid enters blood of human body circulation function and receiving medical liquids simultaneously, the patient can realize transfusion easily in moving process, simultaneously owing to cancelled the infusion bottle that cooperates existing transfusion device to use, the height and position and the vertical position that no longer need keep infusion bottle by extra staff have reduced manpower, have improved the safety of infusing.
