Description

A stopper

technical field

The utility model relates to a liquid stop clamp.

Background technique

Intravenous infusion has the advantages of rapid administration, less irritation, and quick curative effect, and is an important clinical treatment method. As a new type of advanced infusion device, intravenous indwelling needle has been widely used in continuous or intermittent intravenous infusion, blood transfusion, tumor chemotherapy and long-term intravenous hypertrophic therapy. The venous indwelling needle has the function of retention, which not only relieves the pain caused by repeated punctures, improves the success rate of rescue, but also reduces the workload of nurses, and plays an important role in clinical work. However, the indwelling needle sealing clips currently used (as shown in Figure 1) have many disadvantages, the specific manifestations are as follows: (1) After clipping, they stand upright on the skin, making the patient uncomfortable and easily causing damage to the integrity of the local skin . (2) The patient is very easy to touch or be pressed when dressing or covering the quilt, which causes inconvenience to the patient's life. (3) Especially for elderly patients, children or patients who are critically ill and mentally ill, if they accidentally touch the tube sealing clip, it may cause serious consequences such as the indwelling needle falling off and the patient losing a lot of blood, which brings new challenges to clinical nursing work. question. (4) When sealing the tube, it is necessary to withdraw the needle while pushing the liquid, which is difficult.

Contents of the invention

Aiming at the above-mentioned prior art, in order to overcome the deficiency of the existing pipe sealing clip, the utility model provides a new pipe sealing clip—the liquid stop clip, its structure and operation method are different from the prior art, and it is easier to achieve positive pressure sealing. The tube is easier to operate, the effect of sealing the tube is better, and it will not cause skin damage.

The utility model is achieved through the following technical solutions:

A liquid-stop clamp, comprising a clamp arm I and a clamp arm II connected to each other, wherein a hollow groove I is provided on the clamp arm I, a clamping cap is provided at the end of the clamping arm I, and a clamping cap is provided at the end of the clamping arm II to cooperate with the clamping cap. The middle part of the clamp arm II is provided with several tooth-shaped protrusions distributed along the longitudinal axis, and the two sides of the tooth-shaped protrusions of the clamp arm II are respectively provided with hollow grooves II and hollow grooves III.

The upper surface of the cap is provided with at least one anti-slip pattern.

Hollow grooves II and hollow grooves III are respectively provided on both sides of the tooth-like protrusions of the clamp arm II.

Use: After the infusion is completed, close the regulator of the infusion set, connect the nipple of the syringe of the aspirated 5ml locking solution (heparin saline injection 125U/ml) with the scalp needle of the infusion set, and withdraw while pushing the locking solution. Needle, when there is 1ml of tube sealing solution left, clamp the liquid-stopping clip of the present utility model on the root of the indwelling needle, and then inject 0.5-1ml of tube sealing solution until it cannot be pushed. At this time, insert the heparin cap The scalp needle is pulled out to complete the tube sealing operation.

The liquid-stopping clamp of the utility model is easier to achieve positive pressure sealing, more convenient to operate, better in sealing effect, and will not cause skin damage (it will not stand on the skin after sealing), and has the following advantages:

1. Avoid causing skin damage, reduce the financial burden and pain of patients.

2. Reduce the psychological pressure of patients, which is beneficial to prolong the time of venous catheterization and complete the treatment smoothly.

3. It is safe to use and easy to operate, which improves the work efficiency of nursing staff and avoids the occurrence of medical disputes.

4. Increase patient comfort.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

A liquid-stopping clamp, comprising interconnected clamping arms I1 and clamping arms II2, as shown in Figure 2, wherein a hollow groove I3 is provided on the clamping arm I1, a cap 4 is provided at the end of the clamping arm I1, and a clamping cap 4 is provided at the end of the clamping arm II2. There is a clamping bolt 5 matched with the clamping cap 4, a number of tooth-shaped protrusions 6 distributed along the longitudinal axis are provided in the middle of the clamp arm II2, hollow grooves II7 and Hollow slot III8. Three anti-slip lines 9 are arranged on the upper surface of the card cap.

Use: After the infusion is completed, close the regulator of the infusion set, connect the nipple of the syringe of the aspirated 5ml locking solution (heparin saline injection 125U/ml) with the scalp needle of the infusion set, and withdraw while pushing the locking solution. Needle, when there is 1ml of sealing liquid left, clamp the liquid-stopping clip of the present invention on the root of the indwelling needle (the infusion tube is placed between the clamping arm I1 and the clamping arm II2, pinch the clamping arm I1 and the clamping arm II2 with your fingers tight, then the latch 5 is snapped into the cap 4 to fix it, and the infusion tube is squeezed into the hollow groove I3 under the action of the tooth-shaped protrusion 6 at this time, thereby being closed), and then inject 0.5-1ml to seal Tube fluid until it can not be pushed, at this time, pull out the scalp needle inserted into the heparin cap to complete the tube sealing operation.
