Description

Spiral needleless blood sampling device

Technical Field

The utility model relates to the technical field of medical equipment, specifically speaking especially relates to a spiral needleless blood sampling device.

Background

The use of keeping somewhere the needle in clinic can reduce the patient because of relapse the misery that the vein puncture caused and to the fear sense of making the needle, alleviate patient's the anxiety, be convenient for clinical medication, urgent, critical patient's rescue medication, alleviate nurse's work load, it is painful to reduce the patient, therefore the vein is kept somewhere the needle and is being used widely in clinic, in the face of this special colony of patient, the length of vein is kept somewhere needle and patient's comfortable becomes nurse and the housewife problem of paying the most attention to, also be the prerequisite of keeping somewhere the sign and popularization that the needle was used successfully.

"needle stick injury" refers to accidental injury caused by medical sharp instruments such as needles, blades, etc., resulting in deep skin lesions and bleeding. In recent years, with the enhancement of occupational protection awareness, attention has been paid to acupuncture as an occupational injury caused by occupational exposure.

However, the current situation of clinical acupuncture is not optimistic, and the reporting system after acupuncture is still unsatisfactory. According to the report of the American blood exposure prevention and treatment reporting network system, the probability of needle stick injury of nurses is always the highest among all medical staff for many years, and accounts for 45% of the medical staff in 2002 and 37.8% in 2003. The questionnaire survey of 1075 nurses by the chinese scholars in 2003 showed that the incidence of needle stick injuries was 80.6%, similar to the foreign reports, 3.5 needle stick injuries per year, 3780 needle stick injuries occurred by 866 nurses in 1 year, of which the contaminated needle sticks accounted for 60%.

However, in the prior art, the blood drawing of the indwelling needle is to directly prick a blood drawing needle head on the indwelling needle connector, so that the secondary puncture of a patient is reduced, but the risk of needle stick injury is higher.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of the prior art, the embodiment of the utility model provides a spiral needleless blood sampling device. The technical scheme is as follows:

in one aspect, a spiral needle-free blood collection device is provided, comprising: the device comprises a spiral connector, a transparent hose, a tail needle and a rubber hose protective sleeve;

one end of the transparent hose is connected with the spiral connector, and the other end of the transparent hose is connected with the tail needle; the rubber hose protective sleeve is wrapped outside the tail needle; one end of the spiral connector is connected with the transparent hose, and the other end of the spiral connector is provided with a connector; the interface is used for connecting an infusion scalp needle, a venous indwelling needle, a venous catheter or an indwelling drainage tube.

Further, the spiral connector is a tightening connector matched with an arteriovenous indwelling catheter, a scalp needle or a drainage tube.

Furthermore, the spiral connector and the transparent hose are made of PVC materials.

Further, the venous catheter is a double-cavity central venous catheter, a three-cavity central venous catheter or a multi-cavity catheter; the indwelling drainage tube is used for draining pericardial effusion, pleural effusion or abdominal effusion.

Further, tail needle outsourcing has the rubber hose protective sheath, automatic resilience during separation tail needle and sample collector.

The embodiment of the utility model provides a beneficial effect that technical scheme brought is:

from the patient's perspective:

1. the spiral needle-free blood sampling device is matched with the arteriovenous indwelling needle, so that secondary puncture blood sampling can be avoided;

2. the fear and the pain of the patient are relieved;

3. reasonably utilizing the blood vessel to protect the blood vessel of the patient;

4. repeated puncture is reduced, and the risk of infection is reduced;

5. the medical cost of the patient is reduced.

From the nurse's perspective:

1. secondary puncture blood drawing is avoided, the operation difficulty is reduced, and the flow is simplified;

2. a needle head is not needed, so that the medical staff is prevented from being injured by the needle;

3. the indwelling catheter specimen is reserved and taken, and exogenous pollution is avoided.

4.
