Description

Improved venous indwelling needle

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to needle is kept somewhere to improved generation vein.

Background

The venous indwelling needle consists of a stainless steel needle core, a soft outer sleeve and a plastic needle seat, wherein the outer sleeve and the needle core are punctured into a blood vessel during puncture, and the needle core is drawn out after the sleeve is sent into the blood vessel, so that only the soft outer sleeve is left in the blood vessel for transfusion. After one transfusion, the soft cannula is sealed and fixed properly by positive pressure, and is used again when the next transfusion is finished, and the soft cannula can be left in the human body for 72 to 96 hours. The use of venous indwelling needles is increasing based on medical advantages and technical factors. The disposable venous indwelling needle is used in venous transfusion, so that the venous puncture times are reduced, and the venous puncture time interval is prolonged. And the operation is simple and convenient, the success rate is high, the side effect is small, the pain of a patient is relieved, and the timely and safe medication is ensured. The workload of medical staff is reduced, and the medical staff is effectively prevented from avoiding blood pollution except injection.

The existing vein indwelling needle consists of a stainless steel core, a soft outer sleeve, a plastic needle seat and the like, wherein the indwelling needle with the structure has a height difference between an indwelling needle hose and the plastic needle seat, and after the indwelling needle hose is covered by transparent dressing, the indwelling needle soft sleeve is easy to fold, so that instillation is not smooth, the position needs to be frequently adjusted, and the clinical workload is increased; the existing indwelling needle hose is not provided with any mark, and due to the operation habit, when part of nurses push the soft trocar, the pushing is excessive, so that the plastic needle seat is tightly attached to the skin puncture point, the friction force is increased, and the puncture part is painful; in addition, the puncture point has blood seepage and local red and swollen, so the infection and the pad pasting drop are easily caused, the pad pasting needs to be replaced, and the workload is increased.

SUMMERY OF THE UTILITY MODEL

To the problems existing in the prior art, the utility model aims to provide an improved generation vein indwelling needle.

The utility model discloses a following technical scheme realizes:

the improved venous indwelling needle comprises an indwelling needle, an indwelling needle hose and a plastic needle seat, and is characterized in that the plastic needle seat comprises a plastic handle connected with an extension pipe and an elastic part extending from the plastic handle to the direction of a needle head, and the front end of the elastic part is coated on the outer wall of the indwelling needle hose until the outer wall of the indwelling needle hose and the outer wall of the indwelling needle hose are positioned on the same horizontal plane.

The improved venous indwelling needle is characterized in that the side surface of the elastic part is in an isosceles triangle shape, the cross section of the elastic part is in an isosceles trapezoid shape, and the elastic part is in a duckbill shape as a whole.

The improved venous indwelling needle is characterized in that the outer wall of the indwelling needle hose is provided with an optimal needle feeding scale mark.

The improved venous indwelling needle is characterized in that a circle of gelatin sponge is sleeved on the outer wall of the indwelling needle hose.

The improved venous indwelling needle is characterized in that the gelatin sponge is arranged between the optimal needle feeding scale mark and the elastic piece.

The improved venous indwelling needle is characterized in that the elastic piece is a silica gel pad.

The improved venous indwelling needle is characterized in that the optimal needle feeding scale lines are set to be colored lines.

The utility model has the advantages that the height difference is reduced by arranging the elastic part and the slope of the elastic part, the folding probability of the remaining needle soft sleeve is reduced, and the excessive needle feeding is avoided by the best set needle feeding scale mark as the reminding; through the gelatin sponge who sets up, can adsorb a small amount of oozing blood exudate, also can reduce the friction of hard plastic needle file and skin puncture point, increase the comfort level.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

in the figure, 1-a flexible tube of an indwelling needle, 2-a plastic needle seat, 3-an elastic part, 4-a scale mark, 5-gelatin sponge and 6-a plastic handle.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings, and specific embodiments will be given.

The utility model relates to a needle is kept somewhere to improved generation vein should keep somewhere the needle and carry out little change on current basis to solve the uncomfortable sense that the needle brought for the patient when using and reduce medical personnel's work load of keeping somewhere now.

The improved structure of the medical needle comprises a remaining needle, a remaining needle hose and a plastic needle seat, wherein the plastic needle seat comprises a plastic handle connected with an extension pipe and an elastic part extending from the plastic handle to the needle head direction, the front end of the elastic part is coated on the outer wall of the remaining needle hose until being positioned on the same horizontal plane with the outer wall of the remaining needle hose, the elastic part selects a silica gel pad, the side surface of the elastic part is in an isosceles triangle shape, the cross section of the elastic part is in an isosceles trapezoid shape, and the whole plastic needle seat is in a duckbilled shape. This setting has reduced the difference in height between keeping somewhere needle hose and the plastics needle file on the one hand to greatly reduced keeps somewhere the probability that the needle hose was discounted after covering transparent auxiliary material, ensures that instillation is smooth and easy, and on the other hand, the silica gel pad replaces hard plastics needle file and skin contact, increases patient's comfort level.

Continuing to refer to fig. 1, for providing medical personnel's the most audio-visual judgement, be provided with the best on the outer wall of remaining needle hose and send the needle scale mark, the setting of this scale mark, medical personnel of being convenient for very clear and definite judgement occasionally in the operation avoids the propelling movement excessively to prevent that plastics needle file from laminating too tightly with skin puncture point, the very big operation that has made things convenient for medical personnel, for making the scale mark more striking, send the needle scale mark to the colour lines with the best.

With reference to fig. 1, as an improvement, a circle of gelatin sponge is sleeved on the outer wall of the indwelling needle hose, the specific position is between the optimal needle feeding scale line and the elastic piece, the arrangement can absorb a small amount of blood seepage at the puncture point position, and simultaneously has an antibacterial effect, and simultaneously, the friction between the hard plastic needle base and the skin puncture point can be reduced, and the comfort level is increased.

The above-mentioned each improvement point, though simple in construction, but actually solved various problems appearing in clinic, the cost of manufacture is low, easy to realize, the practicability is stronger.
