Description

Protection pad for central venous catheterization through peripheral venipuncture

Technical Field

The utility model relates to a protection pad, more specifically the protection pad of central vein catheterization through peripheral venipuncture that says so.

Background

Central venous catheterization (PICC) is punctured through peripheral vein, punctures from the vein of peripheral arm with the pipe, and the pipe directly reaches the great vein that is close to the heart, avoids the direct contact of chemotherapy medicine and arm vein, and the blood flow speed of great vein is very fast in addition, can wash the thinning therapy medicine fast, prevents the stimulation of medicine to the blood vessel.

The current method for fixing the central venous catheterization through peripheral venipuncture comprises the following steps: the central venous catheterization tube punctured by the peripheral vein is placed and bent in an S shape, the white fixed wings are buckled, the white fixed wings are fixed by adhering sterile adhesive tapes, the connector is fixed in a sterile manner, transparent adhesive films are adhered, the adhesive tapes are fixed in a butterfly-shaped cross reinforcing manner, and then the heparin cap is fixed transversely by the adhesive tapes. The anti-allergic transparent adhesive film with 10 x 12 is pasted to exhaust bubbles below the adhesive film, so that the catheter, the skin and the adhesive film are integrated.

When the central venous catheter is fixed on the body surface of a patient after peripheral venipuncture, attention needs to be paid to the fact that the arm movement amplitude cannot be too large or too violent during use, and the catheter is prevented from falling off or breaking; in addition, the tube is flushed and the membrane is replaced once a week, the shower is used as much as possible during bathing, and the membrane needs to be replaced in time when the membrane is loosened, so that the catheter is prevented from being blocked or the skin blood vessel at the position of the catheter is prevented from being infected. If PICC maintenance is good, it can be used for up to 1 year or more, which is sufficient to maintain chemotherapy to the end. However, in actual conditions, some abnormalities often occur, mainly because the fixing method has some defects, and abnormal conditions such as movement, looseness and the like of a central venous catheter punctured through a peripheral vein are easily caused; meanwhile, the catheter needs to be fixed by the adhesive plaster, the catheter, the skin and the adhesive film need to be integrated, and if the adhesive property is good, the catheter, the adhesive plaster and the adhesive film need to be separated during replacement, so that some difficulties are generated.

Detailed Description

The current fixing method for the central venous catheterization through peripheral venipuncture in clinic is as follows: the central vein catheterization line punctured by the peripheral vein is directly fixed on the skin of the patient through the adhesive plaster and the adhesive film. The method for directly fixing the catheter has certain problems, mainly including difficult fixing and difficult decomposition. In order to solve the clinical requirement, the direct fixed catheter is changed into the indirect fixed catheter, a protective pad is added between the human skin and the catheter, the protective pad is placed on the human skin, the catheter is fixedly arranged in the protective pad and then covered or bandaged and fixed by a film, the fixing performance and the safety are improved, and the clinical operation requirement is met. In addition, through the transition of the protection pad, the area between the central venous catheterization tube for peripheral venipuncture and the surface of the human body is increased, the pressure of the central venous catheterization tube for peripheral venipuncture on the skin of the human body can be reduced, and the pressure sore is prevented.

The central venous catheterization protection pad through peripheral venipuncture consists of a bottom plate, a straight baffle, a bent baffle, a fixing clip and a round hole.

The central venous catheterization protective pad punctured by peripheral veins is used as a medical product, and the used materials meet the relevant requirements and regulations. The bottom plate is directly pasted on the skin of patient's upper limbs when using, and the upper limbs are the arc, and the bottom plate should be in comprehensive contact with the upper limbs after pasting patient's upper limbs skin, can be along with the upper limbs activity (upper limbs warp) when patient's upper limbs activity, and the bottom plate also can change the radian. The bottom plate is a rectangular soft plate, the thickness of the bottom plate is 1-2 MM, the deformability is good, and medical silica gel is usually adopted; the bottom plate is provided with a round hole which is penetrated through the peripheral venipuncture central venous indwelling catheter, when the peripheral venipuncture central venous indwelling catheter is placed and replaced, the peripheral venipuncture central venous indwelling catheter penetrates into and out of the round hole, and the treatment of the peripheral venipuncture central venous indwelling catheter is facilitated.

The straight baffle and the bent baffle are combined on the bottom plate to form an S-shaped groove, and the outer part (an extension tube, a butterfly wing and a heparin cap) of the central venous indwelling tube body punctured through the peripheral vein is placed in the groove. The straight baffle and the bent baffle are trapezoidal plates, the outer side of each trapezoidal plate is a straight wall, and the inner side of each trapezoidal plate is provided with a little inclination to form a groove with a large upper part and a small lower part. The size of the bottom of the groove is consistent with the size of the outer part (the extension tube, the butterfly wing and the heparin cap) of the central venous indwelling catheter body punctured through the periphery vein, when the outer part (the extension tube, the butterfly wing and the heparin cap) of the central venous indwelling catheter body punctured through the periphery vein is placed in the groove, the outer part is fixed to a certain extent, and the groove with the large upper part and the small lower part is convenient to place and take out the extension tube, the butterfly wing and the heparin cap.

The bottom plate, the straight baffle plate and the bent baffle plate are made of the same material and are processed into a whole, and the positions of the S-shaped grooves for arranging the extension tube, the butterfly wing and the heparin cap can be set according to the sizes of the extension tube, the butterfly wing and the heparin cap, so that the extension tube, the butterfly wing and the heparin cap can be placed more stably.

The fixing clip (U-shaped) is placed on the straight baffle and is clipped at the outer side of the straight baffle, and the outer part (extension tube, butterfly wing and heparin cap) of the central venous indwelling catheter body is further fixed through peripheral venipuncture. The U-shaped fixing clip has certain elasticity, and when the fixing clip is clamped on the outer straight walls of the straight baffles, the fixing clip is tightly clamped on the outer straight walls of the two straight baffles to control the movement of the outer part (the extension tube, the butterfly wing and the heparin cap) of the central venous indwelling catheter body after the peripheral venipuncture and prevent the outer part (the extension tube, the butterfly wing and the heparin cap) of the central venous indwelling catheter body after the peripheral venipuncture from loosening. In addition, the fixing clip can also adopt an adhesion type, an adhesive is arranged at the straight wall at the inner side of the fixing clip, and the fixing clip is in adhesion connection with the straight baffle by the adhesive. The number of the fixing cards can be selected by the operator.

Under the condition of ensuring that the outer part (the extension tube, the butterfly wing and the heparin cap) of the central venous indwelling catheter body is reliably fixed through peripheral venipuncture, discomfort to a patient is reduced as much as possible, and the periphery of the bottom plate is provided with a plurality of air holes for ventilation.

The central venous catheter protection pad for peripheral venipuncture can adopt an adhesive type or a wrapping type in use. When the protective pad is used for the central venous catheterization through the peripheral venipuncture, the pressure on the local part of a patient can be reduced, and the pressure sore is prevented.
