Abstract
The utility model relates to a two-way automatic shutoff safety transfusion device which comprises a Murphy's tube, a transfusion tube, a flow regulator, a liquid inlet end head and a liquid outlet needle head. The utility model is characterized in that a liquid inlet of the liquid inlet end head forms a conical shape, a blocking frame which corresponds to the liquid outlet is arranged in the liquid passing cavity of the liquid inlet end head and a float which is matched with the liquid outlet is arranged in the blocking frame. The back end of the liquid outlet needle head is provided with a one-way liquid passing device, and an exhaust hole which is communicated with the liquid passing cavity and provided with a sealing cover is arranged on the liquid inlet end head. The utility model has the advantages of simple structure, low price, convenient operation, etc. The two-way automatic shutoff of transfusion passages can be realized by the utility model, and the blood return of patients or the air enter in the bodies of the patients can be prevented.
Description
This utility model relates to a kind of medical apparatus, particularly a kind of infusion set of the usefulness of infusing.
Existing transfusion device generally is to be made of the Fei Shi pipe in the Meng of bringing liquid passage and liquid outlet channel into, is provided with an external hand governor on liquid outlet channel.The transfusion device of this structure exists following deficiency, and whether patient or nurse personnel careful attention liquid constantly are totally lost, if do not realize, after medicinal liquid is totally lost, liquid level will constantly descend, to making the air admission human body or cause blood back danger, and when the nurse changes liquid, then to readjust, the following air of Fei Shi pipe in the Meng is drained, and so, patient is when transfusion, constantly note the rest that transfusion device can not get loosening because of having to, and increase the loaded down with trivial details property of nurse operation; If another of this transfusion device is not enough is exactly the patient that infused because of going to toilet or other thing needs when mobile, and walking is inconvenience extremely, accidentally, is easy to cause blood back.In order to solve this this problem, many technical staff have done number of research projects, in conjunction with electronics technology, produce the electronic infusion pump, speed governing more accurately, and when liquid is totally lost, give the alarm, but its cost is very expensive, can only use on the bed side, thereby can not get using widely.
The purpose of this utility model just provides a kind of two-way automatic-diversion closure safe transfusion system simple in structure, cheap and easy to use, and it can automatically prevent in patient's blood back or air admission patient's the body.
The purpose of this utility model is to realize by such technical scheme, it includes Fei Shi pipe in the Meng, tube for transfusion, flow regulator, feed liquor termination and liquid discharging pinhead, it is characterized in that: the liquid outlet of feed liquor termination is tapered, crossing in the sap cavity of feed liquor termination is provided with and the corresponding shelf of liquid outlet, be placed with the float that matches with liquid outlet in the shelf, the rear end of liquid discharging pinhead is provided with unidirectional liquid device, and the feed liquor termination is provided with the steam vent of the with closure that communicates with the mistake sap cavity.
Operation principle of the present utility model is such: during transfusion, the float in the feed liquor termination upwards floats under buoyancy, and shelf guarantees that float can only vertically move, prevent from laterally to move about it, and the long height that rises on the restriction float, at this moment, liquid outlet is unobstructed, can infuse normally; When the medicinal liquid in the infusion bottle was totally lost, float moved down, and blocks liquid outlet, stoped liquid flow in the infusion channel, had prevented that air from flowing into human body; The effect of unidirectional liquid device is only to allow the medicinal liquid one-way flow, prevents patient's blood back.
Owing to adopted technique scheme, the utlity model has following advantage:
1. simple in structure, low cost of manufacture;
2. easy and simple to handle, do not need special operant skill; After liquid was totally lost in the infusion bottle, float was blocked the liquid outlet of feed liquor termination automatically, formed automatic-diversion closure, prevented in air admission patient's the body, make the nurse to change the liquid operation more convenient, also make patient or nursing staff needn't be constantly expend energy on egregiously.
3. security insurance, when the liquid in the liquid discharging pinhead will reflux, the lightweight motion stops was blocked the inlet of liquid discharging pinhead automatically, prevented patient's blood back, guaranteed safety.
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation of feed liquor of the present utility model termination;
Fig. 2 is the structural representation of liquid discharging pinhead of the present utility model.
Among the figure: 1. liquid outlet; 2. cross sap cavity; 3. shelf; 4. float; 5. cross sap cavity; 6. inlet; 7. shelf; 8. feed liquor termination; 9. liquid discharging pinhead; 10. lightweight motion stops; 11. steam vent.
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, this utility model includes Fei Shi pipe in the Meng, tube for transfusion, flow regulator, feed liquor termination 8 and liquid discharging pinhead 9, it is characterized in that: the liquid outlet 1 of feed liquor termination 8 is tapered, crossing in the sap cavity 2 of feed liquor termination 8 is provided with and liquid outlet 1 corresponding shelf 3, be placed with the float 4 that matches with liquid outlet 1 in the shelf 3, the rear end of liquid discharging pinhead 9 is provided with unidirectional liquid device, and feed liquor termination 8 is provided with the steam vent 11 of the with closure that communicates with mistake sap cavity 2.
Operation principle of the present utility model is such: during transfusion, float 4 in the feed liquor termination 8 upwards floats under buoyancy, shelf 3 guarantees that float 4 can only vertically move, prevent from laterally to move about it, and the long height that rises on the restriction float 4, at this moment, liquid outlet 1 is unobstructed, can infuse normally; When the medicinal liquid in the infusion bottle was totally lost, float 4 moved down, and blocked liquid outlet 1, stoped liquid flow in the infusion channel, had prevented that air from flowing into human body; The effect of unidirectional liquid device is only to allow the medicinal liquid one-way flow, prevents patient's blood back.
As shown in Figure 2, unidirectional liquid device is arranged on crossing in the sap cavity 5 of liquid discharging pinhead 9 rear ends and is provided with and inlet 6 corresponding shelf 7, and inlet 6 is tapered, is placed with the lightweight motion stops 10 that matches with inlet 6 in the shelf 7.It is work like this: during transfusion, medicinal liquid is pushed lightweight motion stops 10 open, and inlet 6 is unimpeded, can infuse normally, and the effect of shelf 7 is to guarantee that lightweight motion stops 10 moves vertically, and prevents that it from laterally moving, and limits the distance that it moves.When the medicinal liquid in the liquid discharging pinhead 9 refluxes, can promote lightweight motion stops 10 and block inlet 6, automatically prevent patient's blood back.
Described float 4 can be an air bag, also can be other floaty soft spheroid, contacts with the airtight of liquid outlet to guarantee it.
