Abstract
The utility model discloses a heating injector with constant temperature for veins, and the utility model is composed of an injector composed of a dripping pot, a buffer, a flow regulator, a needle head, etc. and a heater composed of a PTC heating element, a control switch for single and bidirectional heating, an indicator lamp and a power supply. The buffer is heated by a heating circuit through the PTC heating element to implement a patient's requirement of liquid medicine temperature in infusion. The problems of the patient's discomfort, infusion reactions, etc. caused by lower liquid medicine temperature in frigid seasons and areas can be solved by using the utility model.
Description
This utility model relates to a kind of medical Transfusion device that can make medicinal liquid keep uniform temperature.
At present, in the clinical transfusion,, and cause infusion reaction usually because fluid temperature is low excessively.Particularly northern severe winter, this phenomenon often occur especially, and this increases unnecessary trouble will for patient's health and smelting treatment work.
The purpose of this utility model is to provide the transfusion device that has the heated at constant temperature function in a kind of venous transfusion.
This utility model is achieved in that this heated at constant temperature transfusion device is made up of transfusion device and heater two parts.The same with general infusion set, transfusion device is formed by dripping kettle, buffer, flow regulator and several parts of syringe needle.The buffer that it is characterized in that transfusion device is the special flat that is.Heater is made up of electric appliance circuits such as the heating of two PTC heater elements, single-direction and dual-direction gauge tap, display lamp and power supplys, and two PTC heater elements are near the both sides of buffer.In infusion process, the medicinal liquid of the buffer of flowing through, under the heating of PTC heater element, temperature is improved, and by control single-direction and dual-direction heater switch fluid temperature is adjusted to suitable degree, to satisfy the needs of patient to fluid temperature.
Because the PTC heater element has good function of use, and adopted the single-direction and dual-direction control circuit, through clinic trial repeatedly, fluid temperature generally can be controlled between 25 ℃-35 ℃, solved preferably because fluid temperature is low excessively, patient causes the problem of infusion reaction.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the structural representation of this transfusion device;
Accompanying drawing 2 is these transfusion device heating part electric appliance circuits schematic diagrams;
By shown in Figure 1, dripping kettle [1], buffer [2], flow regulator [4], syringe needle [5] has formed its buffer of transfusion device part of this utility model and has made as shown in Figure 1 flat, a slice PTC heater element [3] is respectively arranged in the buffer both sides, this element and switch [6], display lamp [7], power line [8] are formed heater, by two switches about control, can realize the single-direction and dual-direction heating of buffer, satisfy purpose the medicinal liquid heated at constant temperature.
Claims (2)
1, a kind of vein heated at constant temperature transfusion device, comprise by dripping transfusion device and the heating part branch that a kettle, buffer, flow regulator, syringe needle etc. form and forming, the buffer that it is characterized in that transfusion device is made pancake, and heating part is made up of electric appliance circuits such as PTC heater element, single-direction and dual-direction heating gauge tap, display lamp, power supplys.
2, vein heated at constant temperature transfusion device according to claim 1, two PTC heater elements that it is characterized in that heating part are to be placed on the both sides of buffer and to be close together.
