Description

Central venous tube fixing device

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to a central venous line fixing device is related to.

Background

The central venous catheter is an intravascular tube directly communicated into the great vein and is mainly used for measuring central venous pressure, large-amount rapid infusion and blood transfusion, long-term drug nutrition supply and hemodialysis.

At present, the traditional method is to directly paste the central venous catheter on the skin of a human body by using a medical adhesive tape, after the medical adhesive tape is used for a plurality of days, the sweat absorption performance of the medical adhesive tape is saturated, the viscosity of the medical adhesive tape and the skin of a patient is greatly reduced, the fixing effect is poor, the medical adhesive tape is easy to loosen, and the catheter is easy to fall off when the patient stands up and hangs down and slightly tears the catheter.

Therefore, there is a need for an improved central venous tube securement device of the prior art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a central venous catheter fixing device, avoid central venous catheter not hard up to drop when the patient stands up, the pipe has slight tear.

In order to realize the technical effects, the utility model adopts the technical scheme that: the utility model provides a central venous catheter fixing device, is including being used for wearing in the head hoop of patient's head and the bandage of cover locating outside the head hoop, the bandage with the head hoop is dismantled and is connected, be provided with the fixed subassembly that is used for fixing central venous catheter on the bandage. Through such design, be fixed in the central venous catheter on the bandage, outside the head hoop was located to the bandage cover, the head hoop was worn in patient's head to realize that central venous catheter is fixed in the outer purpose of patient's head, patient's standing up the stress point that the catheter droops and the catheter was torn acts on fixed subassembly, no longer direct action in patient's acupuncture department, thereby avoided the catheter to prick the needle department from patient and drop.

The preferred technical scheme is that the fixing component comprises a base station and a silica gel clamp arranged on the base station, the base station is fixed on the outer surface of the binding band, and the central venous catheter penetrates through and is limited in a clamping groove of the silica gel clamp. Through such design, the central venous catheter is fixed in the silica gel clamp in a limiting way, the silica gel clamp is positioned on the base station, and the base station is fixed on the binding band, so that the fixed connection of the central venous catheter and the hair band is realized.

The preferred technical scheme is that a placing disc is rotatably arranged on the base station, and a limiting component for limiting the placing disc at least two working positions is arranged between the base station and the placing disc; the silica gel clamp is fixedly connected with the placing disc. Through such design, medical personnel can put the angle of dish according to patient's actual condition of pricking and the adjustment of wearing the condition to the double-layered groove angle that the silica gel pressed from both sides has been adjusted, makes central venous catheter with the spacing silica gel of being fixed in of optimum gesture in pressing from both sides.

The preferred technical scheme does, spacing subassembly is including the first skewed tooth group and the second skewed tooth group of mutual spacing cooperation, first skewed tooth group and second skewed tooth group are fixed in respectively on the opposite face of base station and setting plate, the inclined plane of first skewed tooth group and the inclined plane of second skewed tooth group set up relatively. Through such design, but the setting plate manual rotation, when setting plate stall simultaneously, also can realize the fixed of its position.

The preferred technical scheme does, the silica gel presss from both sides and is provided with a plurality of. Through the design, the central venous catheter can be fixed on the silica gel clamp in an S shape, and the fixing effect of the central venous catheter is enhanced.

Preferably, the strap is provided with a binding piece for fixing the strap to the upper limb of the patient. Through the design, when a patient stands up and moves, the embarrassment that the male patient wears the head band is avoided, the head band in the binding band can be pulled out, and the binding band is fixed on the upper limb of the patient, so that the fixation of the central venous catheter is realized, and the embarrassment is avoided; when the patient lies back on the sickbed, the head band is penetrated into the binding band and worn on the head of the patient; or the patient still fixes the bandage on the upper limbs, when meetting the patient that sleeps relatively poorly, easily stand up and oppress central venous catheter and lead to the emergence of medical malpractice, when the head hoop was worn on the patient head, if the patient stands up, the head hoop can force the patient to lie flat naturally or adjust the posture of reviving, has avoided the oppression choked flow of central venous catheter.

The preferred technical scheme does, the binding piece is hair portion and thorn portion that the magic subsides are mutual adhesion fit. By the design, the purpose that the binding band is bound on the upper limb can be achieved; as an equivalent alternative, the binding may also be a snap fastener or the like.

The preferred technical scheme is that the hair part and the thorn part are both arranged on the same side of the binding band, and the hair part and the thorn part are far away from the head of the patient. Through the design, the influence on the comfort level of a patient caused by the contact of hair or thorn parts with the scalp of the patient when the head band is worn is avoided; when the binding band needs to be bound on the upper limb of a patient, the hair part or the thorn part can be bonded only by encircling one end of the hair part or the thorn part for 180 degrees around the extension direction of the binding band.

The preferred technical scheme is that the binding band is arranged in a hollow mode, one end of the binding band is arranged in a closed mode, and an opening for the head hoop to penetrate through is formed in the other end of the binding band. Through such a design, the detachable connection of the head band and the binding band can be realized.

The preferred technical scheme is that the head band is arranged in a C shape. By such a design, the wearing of the head band can be more secure.

The utility model has the advantages and the beneficial effects that: the utility model discloses central venous catheter fixing device is rational in infrastructure, can dismantle through bandage and head hoop and be connected and set up fixed subassembly on the bandage, on central venous catheter was fixed in the bandage, can realize central venous catheter and patient head or upper limbs purpose fixed mutually, outside central venous catheter's the power of dragging act on fixed subassembly, and the stress point direct action of having avoided dragging leads to the pipe to drop in the puncture point.
