Multifunctional indwelling soft needle clip

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a multi-functional soft needle clamp of keeping somewhere.

Background

Hemodialysis is one of the major renal replacement therapies for patients with renal failure. When hemodialysis is performed, a doctor firstly establishes a blood vessel access of a patient, then connects a pre-filled dialyzer and a disposable blood vessel to the blood vessel access of the patient, establishes extracorporeal circulation and starts hemodialysis treatment.

Conventional hemodialysis needle is thicker steel needle, because the syringe needle of steel needle is very sharp, will place patient's blood vessel in for a long time again, carelessly a little, and the hemodialysis needle is probably to puncture the blood vessel, so many hospitals introduced the hemodialysis of bilayer structure and kept somewhere soft needle, send the blood vessel through inside steel needle with outside soft needle earlier, take out the steel needle again, keep somewhere that soft needle can not stab the blood vessel, safer.

However, there is no butterfly wing for holding on both sides of the soft indwelling needle for hemodialysis, so that the medical staff can only directly pinch the needle handle of the soft indwelling needle to insert it into the blood vessel of the patient, and the soft indwelling needle forms a certain angle with the blood vessel of the patient and cannot be parallel to the blood vessel, thereby risking to stab the blood vessel. In addition, no clamp is arranged on the hemodialysis indwelling soft needle, in actual use, medical care personnel need to clamp the soft tube of the indwelling soft needle by using vascular forceps firstly, then connect a catheter on the hemodialysis machine with the indwelling soft needle, and finally loosen the vascular forceps, so that the operation is inconvenient, and the vascular forceps are heavy and difficult to fix.

Chinese patent CN103463691B discloses a venous indwelling needle for hemodialysis, in which a butterfly wing and a clip are respectively provided on the indwelling soft needle, however, the steps of respectively installing the butterfly wing and the clip are very complicated during the production process.

Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Referring to fig. 1, fig. 1 is a schematic view of a multifunctional indwelling soft needle clip according to an embodiment of the present invention. The utility model relates to a multifunctional indwelling soft needle clip, which comprises a bandage 1 and a sleeve 2.

Bandage 1's one end is stiff end 11, bandage 1's the other end is expansion end 12, sleeve 2's outer wall and bandage 1 fixed connection, and sleeve 2 is close to stiff end 11 and sets up, first bayonet socket 13 has on bandage 1, second bayonet socket 14 and third bayonet socket 15, first bayonet socket 13's opening is towards first direction, second bayonet socket 14 and third bayonet socket 15's opening all is towards the second direction, first direction and second direction are opposite, first bayonet socket 13 is located between sleeve 2 and stiff end 11, second bayonet socket 14 and third bayonet socket 15 all are located between sleeve 2 and expansion end 12, second bayonet socket 14 and third bayonet socket 15 cooperate with first bayonet socket 13 respectively.

Preferably, the utility model discloses a multi-functional soft needle clamp of keeping somewhere still includes two briquetting 3, two briquetting 3 respectively with bandage 1 fixed connection, and two briquetting 3 set up respectively in telescopic 2's both sides.

Please refer to fig. 2 in combination, fig. 2 is a schematic view of the multifunctional indwelling soft needle clip and the hemodialysis indwelling soft needle according to an embodiment of the present invention. In practical application, the sleeve 2 is sleeved on a hose for retaining the soft needle 4, and the specific using method comprises the following steps: firstly, the third bayonet 15 is turned over and connected with the first bayonet 13, the annular bandage 1 is pinched from two sides, the needle head of the remaining soft needle 4 is inserted into a blood vessel of a patient, and the middle steel needle is immediately drawn out, because the annular diameter formed by winding the bandage 1 at the moment is larger, the two pressing blocks 3 are in a relaxed state, the middle sleeve 2 cannot be extruded, the hose of the remaining soft needle 4 is smooth, and the bandage 1 is used as a handheld part, so that the remaining soft needle 4 is parallel to the blood vessel when being inserted into the blood vessel, and the blood vessel cannot be punctured; then, when blood returns in the hose for retaining the soft needle 4 are seen, the first bayonet 13 is separated from the third bayonet 15 immediately, the first bayonet 13 is connected with the second bayonet 14, and because the distance between the first bayonet 13 and the second bayonet 14 is short, the two pressing blocks 3 can press the sleeve 2 in the middle, and the sleeve 2 is closed to drive the hose for retaining the soft needle 4 to be closed; then, the movable end 12 is turned over to be attached to the skin of the patient, the part between the second bayonet 14 and the movable end 12 of the bandage 1 is attached to the skin of the patient through adhesive tape, so that the indwelling soft needle 4 is fixed, and the hemodialysis tube is connected with the indwelling soft needle 4; finally, the first bayonet 13 is separated from the second bayonet 14, and the tube for retaining the soft needle 4 is opened again to perform the hemodialysis treatment. After the treatment is completed, the first bayonet 13 and the second bayonet 14 are reconnected, the flexible tube for retaining the flexible needle 4 is clamped closed, and the hemodialysis tube is removed. The utility model discloses a soft needle of multi-functional indwelling presss from both sides has had the effect that butterfly wing and pipe pressed from both sides concurrently, both can do handheld portion use when pricking the needle, can close the hose clamp again, can also be fixed by the adhesive tape, need not to use vascular pincers, and convenient to use has improved medical personnel's work efficiency, and shared space is little.

Preferably, stiff end 11 is square, and expansion end 12 is semi-circular, and when keeping somewhere the hose clamp of soft needle 4 closed, stiff end 11 supported skin with certain angle, and square stiff end 11 is flat line, can not oppress skin, has improved the comfort level, and semi-circular expansion end 12 can increase the space that the adhesive tape was pasted, makes the utility model discloses an it fixes more firmly to keep somewhere the soft needle clamp.

Preferably, the distance between the sleeve 2 and the fixed end 11 is a first distance, the distance between the sleeve 2 and the movable end 12 is a second distance, and the ratio of the second distance to the first distance is 2-3, and the range includes 2 and 3. When the first bayonet 13 and the third bayonet 15 are connected in the range, the two pressing blocks 3 are in a relaxed state and do not extrude the sleeve 2, when the first bayonet 13 is connected with the second bayonet 14, the two pressing blocks 3 extrude the sleeve 2 from two sides, and the sleeve 2 extrudes the hose inside, so that the hose is clamped.

Preferably, the bandage 1 and the sleeve 2 are both soft, the two pressing blocks 3 are hard, and the two hard pressing blocks 3 can ensure that the hose for retaining the soft needle 4 is absolutely clamped.

The present invention has been described in relation to the above embodiments, which are only examples for implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, all changes and modifications which do not depart from the spirit and scope of the present invention are deemed to fall within the scope of the present invention.
