Description

Radial artery puncture assistor

Technical Field

The utility model relates to a medical appliance, in particular to a radial artery puncture assistor.

Background

In medicine, the analysis of arterial blood gas can quickly and accurately describe respiratory function and acid-base balance disorder, is the most reliable index and basis for diagnosing respiratory failure, is widely applied to clinic, and is particularly applied to severe rescue. Invasive arterial blood pressure monitoring is also a common monitoring means of clinical critical medicine, arterial puncture is required, and at the present stage, the radial artery puncture technology applied clinically at home and abroad mainly comprises a conventional puncture technology and radial artery puncture under ultrasonic guidance. Observation shows that the radial artery is generally preferred for the puncture part, and when the conventional puncture technology of the radial artery is adopted, the puncture blood vessel is most frequently selected in clinic for the radial artery, but as the wrist radial artery is positioned in the longitudinal sulcus between the radial flexor tendon and the lower end of the radius, the blood vessel branches of the radial artery at the puncture part are relatively few, the walking ratio is relatively straight and shallow, and the wrist joint is not easy to fix and slide, the back-opening angle is not enough, the skin is not tensed, and the blood vessel is easy to slide during puncture; the subcutaneous nerve endings of the wrist joints are rich, pain is obvious during puncturing, patients are not easy to cooperate, meanwhile, the puncturing skill of nurses is mastered, the positions of the wrists are put, and the like possibly have differences, so that the puncturing and tube placing operation of the nurses is easy to fail. Currently, no existing equipment and instruments are clinically used for properly fixing the wrist joint of a patient and keeping the puncture position, local materials are mostly adopted by nurses, for example, a small soft pillow or bandage coil is padded at the wrist joint, another nurse is often needed to assist in grasping the forearm and the palm, but the patient often cannot be well matched due to pain during operation, and the soft pillow or bandage coil cannot be properly attached to the wrist joint, so that the wrist joint is difficult to be reversely arched to form an optimal angle (120 degrees) and effectively fixed, skin tightness is easily caused, blood vessels are not straightened, and the puncture difficulty is high. Meanwhile, the artificial fixation of the wrist joint easily causes over-extension or insufficiency of the angle, causes discomfort of a patient and poor puncture angle, easily causes puncture failure, and increases the occurrence of operation complications such as bleeding of a puncture part, hematoma of a forearm and the like. The radial artery puncture technology under the ultrasonic guidance is considered to be not suitable for clinical popularization and application in China due to the facts that the radial artery puncture technology under the ultrasonic guidance needs to be completed together with ultrasonic scientific cooperation, extra expenses are added, requirements on personnel qualification and the like and influences on blood sampling flow, time and economy of patients are considered. Is not easy to be popularized in clinic for improving the success of radial artery puncture. Many studies are currently being conducted only in terms of the angle of needle insertion, the skill of needle insertion technique, and blood vessel visualization, but few studies are being conducted in terms of fixation and placement.

SUMMERY OF THE UTILITY MODEL

To the problem that radial artery puncture existed among the above-mentioned prior art, the utility model discloses from effective fixed with keep studying in the aspect of the best puncture position, provide one kind and can solve the common wrist joint of current puncture method reverse bow position angle hyperextension or not enough, fixed insecure wait easily cause the radial artery puncture assistor of the problem of puncture failure.

The to-be-solved technical problem of the utility model is that: radial artery puncture assistor has the base of skin overcoat including the cladding of activity, base one end is fixed continuous with the palm fixed band one end of relative setting, is provided with the primary and secondary on the palm fixed band other end and detains, the fixed finger lasso that is provided with on the palm fixed band, the base other end is fixed continuous with the forearm fixed band one end of relative setting, is provided with the primary and secondary on the forearm fixed band other end and detains, be provided with the support cushion of fixing on the base between palm fixed band and the forearm fixed band, the palm fixed band is located palm portion, forearm fixed band is located the forearm, and the support cushion is located wrist joint portion.

When the puncture needle is used for puncture, the palm is upwards, the wrist joint leans against the supporting soft pad, except for the thumb, the other four parts can be closed and inserted into the finger ring, then the two ends of the palm fixing band are tensioned and the palm part is fixed on the base through the primary-secondary lap joint, the two ends of the forearm fixing band are tensioned and the forearm part is fixed on the base through the primary-secondary lap joint, so that the arm can be fixed on the base, the wrist joint is tightly attached to the supporting soft pad and is not suspended, the optimal reverse-bow angle can be effectively kept, the skin at the puncture position is tight, blood vessels are naturally straightened and fixed, the puncture needle is not easy to deviate during puncture, and the problem that the radial artery puncture is easy to slide is solved.

Radial artery puncture assistor can effectively fix the forearm and, palm portion reduces the patient and does not cooperate the interference, the operation of being convenient for, keeps the reverse bow of wrist joint to make the radial artery more press close to the body surface and easily touches the position, and accurate location best puncture point and needle insertion depth further improve the disposable success rate of radial artery puncture. Meanwhile, the skin is tightened, the resistance is reduced during puncture, the pain of the patient is obviously reduced, the pain of the patient is relieved, and the satisfaction of the patient is improved. Another nurse is not needed to grasp the forearm and the palm of the patient, the labor cost of the nurse is saved, and the working efficiency of the nurse is improved. The arteriopuncture assistor is simple to manufacture, convenient to operate and use and easy to master, and research results are wide in application market and easy to popularize and develop in clinic.

Compared with the prior art, the utility model has the following characteristics:

1. the fixation is firm, the radial artery is easy to touch and position, and the one-time puncture success rate of the radial artery is obviously improved: the reverse bow position required by puncture is effectively kept, the blood vessel is naturally straightened and fixed, the blood vessel is not easy to deviate during puncture, the puncture is easier to be carried out, and the difficulty that the radial artery puncture is easy to slide is solved; the radial artery is more close to the body surface and is easy to touch, the position is more accurate, a nurse can more accurately position the optimal puncture point and the depth of the needle insertion during puncture, the one-time success rate of puncture is further improved,

2. obviously reduce pain of patients during puncture: can reduce the resistance of the skin at the puncture position when the skin is tightly punctured and obviously reduce the pain,

3. reducing patient artifact interference: the base is widened to increase the stability and fix the forearm and the palm part, the uncooperative interference of the patient is reduced,

4. manpower is reduced: convenient operation, firm fixation, no need of another nurse to grasp the forearm and the palm of the patient, saving the labor cost of the nurse,

5. the work efficiency is improved: the puncture success rate is high, the working efficiency of nurses is improved,

6. the practicability is strong: the operation and the use of the device are simple and convenient, and the nurse can easily master the device.
