Description

A fixing device that is used for old patient PICC to put a tub venipuncture

Technical Field

The utility model relates to the technical field of medical equipment, specifically speaking relates to a fixing device that is used for old patient PICC to put a tub venipuncture.

Background

The central venous catheter (PICC) is placed in a peripheral vein, the central venous catheter (PICC) is punctured from a vein of a peripheral arm, the catheter directly reaches a great vein close to the heart, the direct contact between chemotherapy drugs and the vein of the arm is avoided, and the blood flow speed of the great vein is high, so that the chemotherapy drugs can be quickly diluted, and the stimulation of the drugs to blood vessels is prevented.

The PICC has long indwelling time, convenient maintenance and high safety, can avoid the damage to peripheral blood vessels caused by repeated puncture and long-term input of nutrient medicines or irritant medicines, reduces the pain of patients, and becomes a common way for vein treatment of old patients. But the physiological and pathological characteristics of the elderly patients increase the difficulty of PICC retention, and puncture failure is easily caused.

The advantage that improves under the supersound guide and fills a tub in the technique PICC of stopper ding lies in: the puncture is carried out by using the B-ultrasonic direct-vision blood vessel, the exposed catheter is fixed on the upper arm, the success rate is high, and the complication is few. The puncture site is on the elbow, and the basilic vein on the inner side of the upper arm is the first choice when placing the tube. During operation, the ultrasonic probe can be ensured to be perpendicular to and attached to the skin only by extending the arm by 90 degrees and rotating the arm by 60 degrees, the development is most clear, the puncture position is fully exposed, and the operation is convenient. However, most of old patients have poor joint mobility, cannot master abduction and external rotation positions, cannot carry out external rotation in place to cause inconvenience in puncture, the probe is unstable in fixation, the external rotation cannot be endured until the operation is finished, and the arm moves to puncture failure during puncture. While patient comfort is reduced.

The old patients have the defects of hypodermal fat reduction, loose and thin skin, thickened and hardened vein wall, easy rolling of blood vessels, large brittleness and poor elasticity. In the puncture process, an operator is required to hold the ultrasonic probe with one hand and puncture with the other hand, so that the skin cannot be tightened, the blood vessel is not easy to fix, and the sliding is obvious during puncture. An assistant is required to help stretch the skin, fix the blood vessel and keep stable in the whole puncture process so as to prevent the blood vessel from shifting and increase the labor cost.

SUMMERY OF THE UTILITY MODEL

In order to overcome the technical problem, the utility model aims to provide a fixing device that is used for old patient PICC to put a tub venipuncture.

The utility model discloses a fixing device for old patient PICC puts a tub venipuncture, including tourniquet, gasbag, air pump and window, the hemostasis has two, is located respectively the both sides of gasbag, the gasbag links to each other with the air pump, the window with integrative design of gasbag just is located the higher authority of gasbag.

Wherein the air bag and the window are made of soft high polymer materials.

The inflated shape of the air bag is preferably a triangular prism shape, so that loose skin of a patient can be better driven to expose blood vessels.

The window is an observation window or a puncture window with quadrilateral design, the observation window is made of a transparent film, and the middle of the puncture window is hollow. The blood vessel at the puncture position can be better observed and punctured.

Wherein the tourniquet is made of cloth fiber or soft silica gel. Is convenient for disinfection and reuse.

The utility model discloses a fixing device is when using, be fixed in old patient's peripheral arm (upper arm) with the tourniquet and need puncture department both ends, make gasbag (not inflation state) be located the interior elbow department of upper arm, the department that needs puncture can be observed to the window, then adjust the elasticity of tourniquet, keep flat patient's arm and level and smooth placing at the desktop, make gasbag bottom and desktop parallel and level, press down the air pump and aerify the gasbag, along with the gas filled tympanites of gasbag, will relax the skin and drive and make skin department blood vessel expose and suitable puncture thereupon.

The utility model provides a technical scheme can reach following beneficial effect:

the fixing device can support the loose skin and tissue of a patient and be pressed by the inflatable air bag, so that the puncture is facilitated, and the stable body position is kept. The skin can be longitudinally pulled towards two ends during puncture, the puncture point is fixed up and down, the blood vessel is fixed while the skin is tightened, and the puncture success rate is ensured; the proximal end (adopting a buckle tourniquet) has the function of a tourniquet and is convenient and practical.
