Abstract
The utility model discloses a rotary-knob-type transfusion speed regulator, and belongs to the field of medical equipment. The rotary-knob-type transfusion speed regulator comprises a body provided with a transfusion tube through hole, and a speed regulating rod capable of moving up and down, wherein the speed regulating rod is inserted into the transfusion tube through hole from the position above the body. The rotary-knob-type transfusion speed regulator is a matched product of a dispensable transfusion set. In production of the dispensable transfusion set, a transfusion tube is made to penetrate through the transfusion tube through hole of the rotary-knob-type transfusion speed regulator, and therefore the rotary-knob-type transfusion speed regulator can be sleeved on the transfusion tube. When the rotary-knob-type transfusion speed regulator is used, a medical worker rotates a speed regulating rotary knob to a needed dripping speed scale value, the lower portion of the speed regulating rod presses the transfusion tube to deform, therefore, the purpose that medicine liquid dripping speed is accurately controlled is achieved, and the medicine liquid dripping speed can be kept stable. The rotary-knob-type transfusion speed regulator is safe and convenient to use, simple in structure, low in cost and convenient to popularize for use.
Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of knob transfusion speed actuator.
Background technology
Known, the speed of dripping of the disposable transfusion device herb liquid of extensive use at present is to control by the actuator of installing on the tube for transfusion,, pushes tube for transfusion generation deformation by the roller on the sliding damper that is, thus the speed that the control medicinal liquid passes through.But because tube for transfusion has elasticity and outer wall is smooth, rollback takes place in roller easily after adjusting, influence the speed governing degree of accuracy; In addition, patient's limb action also influences the adjusting degree of accuracy of actuator easily, thereby treatment is had a negative impact, and serious also can have an accident, and jeopardizes patient's personal safety.
Also carry out some transformations and innovation at infusion regulator in the prior art, but had problems such as complex structure, reliability be not enough, be unfavorable for utilization and extention.Therefore, a kind of can with the supporting use of disposable transfusion device, have accurate speed-regulating function, and can make stable the remaining on of medicine liquid droplet speed set the common demand that the transfusion speed actuator that drips speed becomes a lot of medical personnel and patient.
The utility model content
The purpose of this utility model provide a kind of simple in structure, easy to use, can accuracy controlling medicine liquid droplet speed, can stablize the maintenance medicine liquid droplet fast and can with the matching used knob transfusion speed of disposable transfusion device actuator.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of knob transfusion speed actuator comprises the main body and the speed control rod moving up and down that are provided with infusion tube via hole, and speed control rod is inserted into infusion tube via hole from the main body top.Infusion tube via hole runs through main body, and its diameter of section and tube for transfusion diameter are complementary, so that tube for transfusion can just in time pass from infusion tube via hole.The speed control rod lower end is stretched out from infusion tube via hole and can be contacted with tube for transfusion, oppresses tube for transfusion by moving up and down of speed control rod and makes its generation deformation in various degree, thereby regulate medicinal liquid by the speed of tube for transfusion.
Above-mentioned speed control rod is screw rod, and main body top is provided with the speed control rod through hole that has female thread that connects main body 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.
Aforementioned body is made of plastics.
This utility model also comprises the speed governing knob that is provided with scale, and the main body 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 medicine liquid droplet speed value, according to " number/minute " the mark scale value, according to speed control rod the level of compression of tube for transfusion and the specification of tube for transfusion are set concrete scale value.
This utility model is the auxiliary products of disposable transfusion device, in the production of disposable transfusion device, tube for transfusion is passed infusion tube via hole of the present utility model, thereby this utility model is enclosed within on the tube for transfusion.During use, to the required fast scale value of dripping, tube for transfusion generation deformation is oppressed in the speed control rod bottom to medical personnel by rotation speed governing knob, thereby reaches the purpose of control medicine liquid droplet speed.
Compared with prior art, the utlity model has following advantage and beneficial effect:
(1) this utility model 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 actuator can regulate and control medicine liquid droplet speed, safe ready accurately, intuitively.
(3) this utility model cost of manufacture is low, and is simple in structure, can with the supporting use of existing disposable transfusion device, and also can promote the use of other any fields that needs liquid droping speed in control flexible pipes, the marketing potentiality are big.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 ~ 4, a kind of knob transfusion speed actuator comprises main body 1, speed governing knob 2 and speed control rod 6.Main body 1 is made of plastics, and runs through the infusion tube via hole 7 of main body about being provided with, and the diameter of section of infusion tube via hole 7 and tube for transfusion 3 diameters are complementary, and tube for transfusion 3 can just in time pass from infusion tube via hole 7, sees Fig. 4.Main body 1 top is provided with the speed control rod through hole that has female thread that connects main body upper surface and infusion tube via hole, speed control rod 6 is screw rod, the female thread of its external screw thread and speed control rod through hole is complementary, and speed control rod 6 can be inserted into infusion tube via hole 7 from the speed control rod through hole, and can move up and down along speed control rod through hole 7.When speed control rod moved up and down, speed control rod changed to the level of compression of tube for transfusion, and variation has also taken place the flow that makes medicinal liquid pass through the tube for transfusion cross section, thereby reached the purpose of accurate adjusting medicine liquid droplet speed.
Protection domain of the present utility model is not limited to above-described embodiment, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model this utility model.If these changes and distortion belong in the scope of this utility model claim and equivalent technologies thereof, then intention of the present utility model also comprises these changes and is out of shape interior.
