Hose blood taking needle

Technical Field

The utility model relates to a blood taking needle, specifically speaking are hose blood taking needle belongs to medical instrument design technical field.

Background

The routine examination project of hospital during blood examination, medical personnel need use the venous blood sampling to carry out the vacuum blood sampling processing to the patient during the inspection, but the blood taking needle that is commonly used in clinical at present has following defect in the blood sampling in-process: 1. most blood taking needles are steel needle structures, and when the blood taking needles are used clinically, blood vessels are already broken when blood is not taken yet, and the puncture parts swell. When blood is collected, if unsmooth blood collection is met, the blood collection needle or the limb of blood collection can be changed frequently, so that the condition that the steel needle punctures the blood vessel is easily caused, the blood vessel is broken and swollen, and the blood collection fails. 2. Blood sampling syringe needle can't be fixed in the use, can take place to rotate sometimes and easily deviate from, brings the sense of fear of psychology for the patient, especially when meetting uncooperative patient (like children, the unusual patient of spirit), the condition of blood sampling needle slippage takes place more easily, can bring the frustration of psychological pressure and puncture once more for the operation nurse. Although more advanced safety blood taking needles exist in the market at present, the safety blood taking needles are complex in structure, high in price, capable of increasing the burden of patients and difficult to popularize.

Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1-4, the embodiment discloses a hose blood taking needle, including blood taking needle 1 and blood taking tube 2, blood taking needle 1 includes puncture steel needle 1.1, blood taking hose 1.2, needle handle 1.3 and block 1.4, puncture steel needle 1.1 activity is worn to establish in blood taking hose 1.2, needle handle 1.3 fixed mounting is at blood taking hose 1.2 rear end, is equipped with joint 1.3a on the needle handle 1.3 afterbody lateral wall, blood taking tube 2 sealing connection is in on joint 1.3a, be equipped with sealing plug 1.5 in the needle handle 1.3 afterbody, the rear end of puncture steel needle 1.1 passes the sealing plug 1.5 and connects block 1.4, block 1.4 covers the cover and overlaps at needle handle 1.3 tail end.

During the specific use, the cap 1.4 is pulled out after the nurse succeeds in puncturing, the puncturing steel needle 1.1 is withdrawn, the blood sampling hose 1.2 is left in the vein, and the blood sampling hose 1.2 is very soft in the blood vessel, so that the blood vessel cannot be punctured easily like a steel needle, adverse effects on the blood vessel cannot be caused, and the blood vessel of a patient can be protected.

As shown in fig. 1, in this embodiment, the needle handle 1.3 is provided with an adhesive wing 1.3b extending to both sides, and an adhesive layer is provided on the lower surface of the adhesive wing 1.3 b. So set up, after the puncture targets in place, tear the barrier paper on pasting the layer, can paste wing 1.3b directly on patient's skin to make blood sampling hose 1.2 steadily fix in the puncture position, can not take place the condition rotatory or deviate from, safe and reliable.

As shown in fig. 1, in this embodiment, a groove 1.3c for facilitating bending of the attaching wing 1.3b is formed on the lower surface of the attaching wing 1.3 b. So set up for paste wing 1.3 b's flexibility of pasting is better.

As shown in fig. 1 to 4, in this embodiment, positioning blocks 1.3d are symmetrically disposed on two sides of the rear portion of the needle handle 1.3, positioning notches 1.4a are symmetrically disposed on two sides of the front end of the cap 1.4, and the positioning blocks 1.3d are correspondingly matched with the positioning notches 1.4 a. So set up, can let and connect steadily reliably between block 1.4 and the needle handle 1.3, avoid the two to take place relative rotation, it is more convenient to operate.

As shown in fig. 1 to 4, in this embodiment, the upper surface of the positioning block 1.3d is a wedge-shaped inclined surface inclined upward from front to back, and the upper side of the positioning notch 1.4a is a bevel edge and is matched with the wedge-shaped inclined surface; the upper portion of the cap 1.4 is provided with a pulling block 1.4b extending upwards, and the front end of the positioning notch 1.4a can be opened by pulling the pulling block 1.4b backwards. So set up, because the last side of location breach 1.4a is the hypotenuse and with wedge inclined plane phase-match, when the corresponding block closure of locating piece 1.3d and location breach 1.4a like this, block 1.4 just can not follow the unexpected dropout of needle handle 1.3 tail end, very safe and reliable. When the cap 1.4 needs to be removed, the front end of the positioning notch 1.4a can be opened only by slightly pulling the upper end of the pulling block 1.4b backwards, the cap 1.4 can be easily removed from the tail end of the needle handle 1.3, and the puncture steel needle 1.1 can be easily withdrawn.

In the utility model, the blood sampling hose 1.2 is preferably made of polyurethane material, and the hardness of the blood sampling hose 1.2 made of polyurethane material is higher when the hose is placed at room temperature, thus being beneficial to puncture; after entering the blood vessel of the human body, the soft tissue can be quickly softened, and the hardness is reduced by more than 70 percent, so that the damage to the blood vessel is obviously reduced. The puncture steel needle 1.1 is preferably made of stainless steel material.

The above description is only for the preferred embodiment of the present invention, and the above specific embodiments are not intended to limit the present invention. Within the scope of the technical idea of the present invention, various modifications and alterations can be made, and any person skilled in the art can make modifications, amendments or equivalent replacements according to the above description, all belonging to the protection scope of the present invention.
