Abstract

A kind of medical catheter or puncture needle locator, pedestal are made up of the base material and sleeve pipe for filling medical adhesive, and barrier paper is covered on medical adhesive and is isolated from the outside；During storage, between base material and barrier paper, the small end of sleeve pipe is leant out through the aperture on base material at the big end of sleeve pipe；In use, throwing off barrier paper, centered on point of puncture, medical adhesive is bonded on the skin around point of puncture, and the large end face of sleeve pipe is adjacent to skin, in conduit or puncture needle plug-in-sleeve, is vertically slowly pierced into, when pin cutting edge of a knife or a sword, which resists sense, to disappear, is locked with lock-screw；Locator can ensure that puncture needle is vertically pierced into skin, ensure the degree that puncture needle enters, prevent plowing from interior tissue, avoid puncture needle from being swung in human body, nurse or trainee or manipulator need not be allowed to hold puncture needle tubing all the time with a hand in whole process of operation.

Description

Medical catheter or needle positioner

technical field

The invention belongs to the field of medical devices, and in particular relates to a medical device for drainage or puncture, which is made of base material, adhesive, catheter and locking screw, and integrates positioning, vertical introduction and auxiliary holding.

Background technique

Perform puncture, ask the patient to take the left or right side lying or sitting position as required, determine the puncture point, lay routine disinfection, assist sterile drape and local anesthesia. Fix the skin at the puncture point with the thumb and index finger or index finger and middle finger of the left hand, and insert the puncture needle vertically along the puncture point with the right hand. When there is a feeling of falling, it proves that it has entered the bone marrow cavity, abdominal cavity or chest cavity.

At present, in the process of puncture, because the hand-held puncture needle is inserted vertically along the puncture point, the visual error causes insufficient verticality and aggravates the pain of the patient; for the work process that cannot extract body fluid at one time, it is often necessary to use hemostatic forceps or artificial Holding the puncture needle or catheter, due to the weight of the hemostatic forceps or the unintentional collision of the operator, the catheter or puncture needle swings and tilts, which also increases the pain of the patient.

Contents of the invention

The technical problem to be solved by the present invention is: when performing puncture, it should be ensured that the puncture needle penetrates the skin vertically, and the degree of penetration of the puncture needle should be ensured as far as possible, so as to avoid scratching the internal tissue and avoid the puncture needle from swinging in the body. There is no need for nurses, interns or operators to hold the puncture needle tube with one hand all the time; the purpose of reducing the pain of patients is achieved, and it is economical, practical, beautiful, and low in cost.

The technical solution adopted by the present invention to solve its technical problems is:

A medical catheter or puncture needle positioner, characterized in that: the base material is covered with medical adhesive, and the surface of the medical adhesive is isolated from the outside world by release paper; the large end of the sleeve is between the base material and the release paper, and the The large end face of the sleeve is parallel to the adhesive surface of the base material, the small end of the sleeve protrudes through the small hole on the base material, and the axis of the sleeve is perpendicular to the large end face of the sleeve; the conduit or The puncture needle is inserted into the cannula, and locked with a locking screw; the release paper is uncovered, the adhesive surface of the base material is adhered to the skin, and the cannula is fixed.

A medical catheter or puncture needle locator as described above is characterized in that: when in use, hold the medical catheter or puncture needle locator with the right hand, peel off the release paper with the left hand, and then use the left thumb and index finger or index finger and middle finger to hold the medical catheter or puncture needle locator. Fix the skin at the puncture point, place the medical catheter or puncture needle positioner on the sterile area with the right hand, align the puncture point with the cannula hole, press the base material with the left hand, and make the medical adhesive stick to the skin; hold the puncture needle with the right hand along the cannula hole Insert the needle vertically at the puncture point. When there is a feeling of falling, it proves that it has entered the bone marrow cavity, abdominal cavity or chest cavity. Tighten the locking screw to position the catheter or puncture needle.

A medical catheter or puncture needle positioner as described above is characterized in that: after use, prepare according to the requirements of puncture, and when it is necessary to pull out the catheter or puncture needle, loosen the locking screw and pull out along the casing hole. Take out the catheter or puncture needle, then peel off the base material, and spread the medical dressing adhesive.

Due to the adoption of the above-mentioned technical scheme, the advantages and positive effects of the present invention are: a medical catheter or puncture needle positioner, the base is composed of a base material and a sleeve coated with medical adhesive, and the medical adhesive is covered with release paper and the outside world. Isolation; when storing, the large end of the sleeve is between the base material and the release paper, and the small end of the sleeve protrudes through the small hole in the base material; when in use, remove the release paper, centering on the puncture point, medical The adhesive sticks to the skin around the puncture point, the large end of the cannula is close to the skin, the catheter or puncture needle is inserted into the cannula, and it is inserted vertically and slowly. When the needle-point resistance disappears, lock it with a locking screw; the locator It can ensure that the puncture needle penetrates the skin vertically, ensures the degree of penetration of the puncture needle, avoids scratching the internal tissue, and prevents the puncture needle from swinging in the body. During the whole operation, it is not necessary for the nurse, intern or operator to hold the puncture with one hand all the time. Needle tube; economical, practical, beautiful, and low cost.
