Abstract
The utility model discloses a portable type infusion speed regulator, and belongs to the field of medical instruments. The portable type infusion speed regulator comprises a clamp body and a speed regulating rod which can move up and down, wherein an infusion tube through hole which penetrates through the clamp body in a front-and-back mode is formed in the clamp body, and the speed regulating rod is inserted into the infusion tube through hole from the upper portion of the clamp body. The deformation degree of an infusion tube is changed through the fact that the speed regulating rod is moved up and down, and therefore the goal of changing flow speed of medicine liquid is achieved. The portable type infusion speed regulator is simple in structure, low in cost, convenient to use, capable of accurately regulating and controlling the flow speed of medicine liquid and enabling the medicine liquid to be maintained in set flow speed, safe, convenient to use, and convenient to popularize and apply.
Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of portable infusion speed regulator.
Background technology
Disposable transfusion device is now in hospital's extensive use, and the speed of dripping of medicinal liquid is controlled by the speed regulator that is installed on the tube for transfusion,, pushes tube for transfusion generation deformation by the roller on the slip speed regulator that is, thereby reaches the purpose of control medicine liquid droplet speed.But there are the following problems for the speed regulator that present disposable transfusion device carries: (1) because tube for transfusion has elasticity and outer wall is smooth, roller is regulated easily generation rollback of back, influences the speed governing degree of accuracy; In addition, patient's limb action also influences the degree of accuracy of speed regulator easily, thereby treatment is had a negative impact, and serious also can have an accident, and jeopardizes patient's personal safety; (2) can not the secondary utilization, cause the wasting of resources.
Carry the problem that speed regulator exists at disposable transfusion device, prior art is improved speed regulator, but exist complex structure, reliability not enough, be unfavorable for problem such as utilization and extention.Therefore, a kind of can be with the supporting use of disposable transfusion device, have accurate speed-regulating function, be easy to carry and reusable transfusion speed regulator becomes medical personnel and patient's common demand.
The utility model content
The purpose of this utility model provide a kind of simple in structure, can accuracy controlling medicine liquid droplet speed, can stablize maintenance medicine liquid droplet speed, reusable and can with the matching used portable infusion speed regulator of disposable transfusion device.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of portable infusion speed regulator comprises clamp and speed control rod moving up and down, runs through the infusion tube via hole of clamp before and after clamp is provided with, and speed control rod is inserted into infusion tube via hole from the clamp top.The speed control rod lower end is stretched out from infusion tube via hole with tube for transfusion and is contacted, and oppress tube for transfusion by moving up and down of speed control rod and make its generation deformation in various degree, thus control medicinal liquid flow velocity.
Above-mentioned clamp comprises train wheel bridge and lower plate, and train wheel bridge links to each other by connecting portion with lower plate, also is placed with spring portion between train wheel bridge and the lower plate so that train wheel bridge and lower plate fit tightly, and infusion tube via hole is positioned at the contact surface place of train wheel bridge and lower plate.Described spring portion is the helical spring of band spring lower limb.
Above-mentioned speed control rod is screw rod, and clamp top is provided with the speed control rod through hole that has female thread that connects clamp upper surface and infusion tube via hole, and speed control rod inserts the speed control rod through hole and can move up and down along the speed control rod through hole.
This utility model portable infusion speed regulator also comprises the speed governing knob that is provided with scale, and the clamp upper surface is provided with the pointer that points to speed governing knob scale, and the lower end of speed governing knob links to each other with the speed control rod upper end, moves up and down by rotation speed governing knob control speed control rod.The scale of speed governing knob is set the level of compression of tube for transfusion according to speed control rod for the numerical value of reflection medicine liquid droplet speed.
This utility model can be carried by medical personnel, when infusing to the patient, this transfusion speed regulator can be clipped on the tube for transfusion of disposable transfusion device, makes tube for transfusion pass infusion tube via hole; Rotate the speed governing knob then and make speed control rod lower end extruding tube for transfusion generation deformation, and obtain suitable medicine liquid droplet speed according to the speed governing knob scale value of clamp upper surface pointer indication, thereby reach the purpose that accurately controlling medicinal liquid drips speed.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) this utility model transfusion speed regulator has overcome the problem of the easy rollback of roller in the speed regulator that existing disposable transfusion device carries, can make medicine liquid droplet speed stable remain on to set drip speed.
(2) design of the scale value of speed governing knob makes this transfusion speed regulator can regulate and control medicine liquid droplet speed, safe ready accurately, intuitively.
(3) this utility model transfusion speed regulator is simple in structure, and is with low cost, easy to use, is easy to carry, reusable, easy to utilize.
