Frosty liquid is injected into the body of people, and not only allowing the body of people, some are cold unavoidably, and when injection due to
Temperature is excessively cool, and body has feeling of pain；People are easy to feel sleepy when being infused, if doctor's nursing is not in time, in infusion bag
When face liquid soon drips off, as a result air also can cause other unsafe conditions such as needle with the body for entering people.This
Outside, it is sometimes necessary to two bottles or two bottles or more the concurrently injected situations of liquid, if separately acupuncture treatment, operation repeat, to infusion
Person brings unnecessary trouble and pain, if liquid mixed, during opening infusion bottle, is easy to introduce air.
Utility model content
For above-mentioned problems of the prior art, the utility model provides a kind of catheter, and structure is simple, side
Just it operates, liquid can not only be heated, and two bottles and two bottles or more liquid medicine can be injected human body together.
To achieve the above object, the utility model provides the following technical solutions:
A kind of catheter, including catheter body, connector and needle for inserting bottle, one end of the catheter body and connector connect
It connecing, the other end is connect with needle for inserting bottle, and heating part is provided on the catheter, and the catheter body includes inner and outer tubes,
The inner surface of the outer tube and the outer surface of inner tube, which are enclosed, is set as a closed seal chamber, and said inner tube is internally provided with channel,
At least 2, the channel, the channel is along inner tube axial alignment.
Further, the heating part includes temperature sensor and heater, and the temperature sensor is located at inner tube and sealing
On the tube wall of chamber contact, inside the heater insertion seal chamber.
Further, the catheter is additionally provided with liquid level sensor, and the liquid level sensor passes through sensing line and liquid level
Warning device connection.
Further, the liquid level sensor is located at catheter body close to one end of connector.
Further, filter screen is provided on the connector.
Further, the seal chamber is provided with cavity hatch, and the cavity hatch is located on the outer surface of outer tube.
Compared with the existing technology, the utility model has the beneficial effects that:
(1) catheter of the utility model, structure is simple, and water is injected in seal chamber, makes coolant-temperature gage liter by heater
Height, and then the fluid temperature of inner tube there is increased, the temperature sensor energy real-time monitoring water temperature of setting guarantees the temperature of liquid
Control will not feel pain because fluid temperature is excessively cool when infusion, be conducive to delay in a suitable temperature, patient
Solve the intense strain of patient.
(2) liquid level sensor of the utility model setting, is used in combination with liquid level alarm device, people can be reminded in time defeated
The surplus of liquid, brings great convenience to staff and patient in liquid bottle.
(3) the utility model is provided with multiple channels, can satisfy two bottles or two bottles or more of liquid and injects together, avoids
Human body multiple syringe needles are penetrated when infusion, reduce repeatedly acupuncture treatment to the unnecessary trouble of patient and pain.
