Abstract

The utility model provides a needleless infusion device. The needleless infusion device comprises an infusion vessel and an infuser; a first connector and a second connector which are convenient for the connection with a needleless conveying tube are arranged at the lower part of the infusion vessel. With the adoption of the needleless infusion device, that a puncture needle punctures a rubber plug of the infusion vessel and a heparin cap of a remaining needle can be avoided, thus small particles can be prevented from entering an infusion system; the needleless device also avoids injury caused by a needle; and therefore, the infection of aids and hepatitis can be reduced, the pollution of infusion particles, relevant reflection of a guide tube and complication of a patient during infusion can be reduced, and the safety of both the patient and medical staff can be ensured.

Description

No-needle transfusion device
Technical field
This utility model belongs to technical field of medical instruments, specifically, relates to a kind of no-needle transfusion device.
Background technology
During medical treatment is clinical, venous transfusion is modal method in treatment patient process.Yet, existing medical personnel are carrying out in infusion process to patient, two ports of transfusion bag, one port connects transfusion device, dosing is convenient in another port, dosing link is generally syringe needle puncture dosing port rubber stopper and completes, and infusion link completes connection by transfusion device upper end puncture transfusion bag fluid infusion port rubber stopper conventionally, and transfusion device lower end is completed by scalp puncture of steel needles remaining needle calparine cap or direct skin puncture.Dosing be connected the process of transfusion device in there will be repeated multiple times bottle closure of rubber or the calparine cap worn, produce contaminant particles, enter transfusion system and cause particle contamination, piercing needle easily causes the generation of pricking wound in addition, the danger that the syringe needle of contact blood samples of patients has diseases such as causing acquired immune deficiency syndrome (AIDS), hepatitis to infect, brings unnecessary misery to patient or medical worker.How to avoid said circumstances, solving the generation of easily sneaking into the risk of contaminant particles in medicinal liquid and reducing pricking wound is the problem that this utility model faces.
Summary of the invention
This utility model provides a kind of no-needle transfusion device, and it can solve and in the piercing process that prior art exists, easily produce contaminant particles and enter the problem of medicinal liquid, and the generation that prevents pricking wound.
In order to solve the problems of the technologies described above, the technical solution of the utility model is,
A no-needle transfusion device, comprises transfusion bag, transfusion device, and the bottom of described transfusion bag is provided with the first joint and the second joint, and described the first joint is convenient to be connected with the carrier pipe of needleless with the second joint.
The carrier pipe of described needleless is transfusion device or syringe.
Described the first joint comprises the first sleeve pipe, in the inside of the first sleeve pipe, be provided with first piston and the first spring, described the first joint is convenient to needleless injector dosing and is used, when the nipple of needleless injector inserts the first joint, can oppress first piston to inside contracting, thereby promote the first spring-compressed, the first joint is opened, and medicinal liquid enters transfusion bag inside via the first joint; After syringe is extracted, the first spring return function drives first piston return, and first piston seals the first joint, avoids medicinal liquid to flow out.
Described the second joint comprises the second sleeve pipe, is provided with the second piston and the second spring in the inside of the second sleeve pipe, and the outside, lower end of described the second sleeve pipe is provided with external screw thread, and described the second joint is convenient to be connected with no-needle transfusion device.When needs are infused, no-needle transfusion device inserts the second joint and screw thread rotation connects, it is connected firmly, prevent that the irritated tractive transfusion device of patient from causing de-pipe, now, the second piston is oppressed to inside contracting, thereby promotes the second spring-compressed, the second joint is opened, and medicinal liquid enters transfusion device via the second joint.
Described first, second joint and described transfusion bag are one-body molded.
Described the first joint and the second joint all adopt positive pressure connector.
The two ends of described transfusion device are equipped with nipple, and described nipple outside is provided with screw-cap.
The two ends of described transfusion device all do not have puncture needle, can also be set with the small cap that keeps aseptic in the outside of nipple.When venous transfusion, remove the small cap at two ends, the upper end nipple of transfusion device is directly connected with the second joint of transfusion bag, and lower end nipple is directly connected with the positive pressure connector of remaining needle, and then dextrorotation tight-spiral cap, firmly connects.
Positive pressure connector is finished parts; when clinical concrete application; the upper end of transfusion device is inserted and is rotatably connected with the positive pressure connector of wherein one end of transfusion bag; the positive pressure connector that inserts the another port that is rotatably connected by needleless injector adds injecting medical liquid; the end of transfusion device is directly connected with the positive pressure connector of patient's remaining needle with it; whole infusion set has really been realized needleless; thereby avoided the contaminant particles producing in piercing process to mix into the liquid; and the generation that prevents well pricking wound, cause unnecessary misery to patient and medical worker.
The positive pressure connector of dosing port: when syringe is pulled up, produce a malleation, automatically make medicinal liquid boost, can prevent that medicinal liquid from flowing out.
This utility model compared with prior art has the following advantages and good effect:
1, do not need lancet puncture rubber stopper and calparine cap, avoid molecule to enter transfusion system;
2, no-needle transfusion, avoids pricking wound, reduces the infection of acquired immune deficiency syndrome (AIDS), hepatitis;
3, reduce infection and the related complication that patient keeps somewhere intravenous needle and conduit, alleviate nursing staff's workload.
Accompanying drawing explanation
Fig. 1 is the using state structural representation of no-needle transfusion device specific embodiment described in the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Shown in figure 1, a kind of no-needle transfusion device, comprises transfusion bag 1, transfusion device 2, and the bottom of transfusion bag 1 is one-body molded the first joint 3 and the second joint 4;
The first joint 3 comprises the first sleeve pipe 31, in the inside of the first sleeve pipe 31, be provided with first piston 32 and the first spring 33, the first joint 3 is convenient to needleless injector dosing and is used, when the nipple of needleless injector inserts the first joint 3, can oppress first piston 32 to inside contracting, thereby promote the first spring 33 compressions, the first joint 3 is opened, and medicinal liquid enters transfusion bag 1 inside via the first joint 3; After needleless injector is extracted, the first spring 33 self-returns drive first piston 32 returns, and first piston 32 sealing the first joints 3, avoid medicinal liquid to flow out.
The second joint 4 comprises the second sleeve pipe 41, and the outside, lower end that is provided with the second piston 42 and the second spring 43, the second sleeve pipes 41 in the inside of the second sleeve pipe 41 is provided with external screw thread 44, the second joints 4 and is convenient to be connected with no-needle transfusion device.When needs are infused, the nipple of no-needle transfusion device upper end inserts the second joint 4 and screw thread rotation connects, and it is connected firmly, now, the second piston 42 is oppressed to inside contracting, thereby promotes the second spring 43 compressions, the second joint 4 is opened, and medicinal liquid enters transfusion device 2 via the second joint 4.
