Technical Field

The utility model relates to the technical field of medical supplies, in particular to a brachial artery interventional puncture fixing device.

Background

The brachial artery is thicker than other arteries, so that the puncture is easier, the brachial artery is generally used as a main puncture object in the puncture operation, the puncture position of the brachial artery is generally below the middle and lower part of the elbow fossa, namely the elbow transverse striation is 0.5-1 cm, and the pulse of the brachial artery before elbow bifurcation is strongest; the puncture method comprises placing upper limb flat, straightening, slightly extending outwards, placing pad adjuvant roll below elbow, finding puncture position, avoiding superficial vein and median nerve, fixing artery, and puncturing along brachial artery towards proximal end direction by single wall puncture method; drawing the tube after the puncture is finished, adopting an elastic bandage to perform compression hemostasis, continuously observing after the puncture is finished, ensuring that the arm is in a straight state until the hemostasis bandage is removed, and gradually bending the arm, otherwise, causing the wound to continuously bleed;

the longest fixing mode used at present is to bind the splint on the arm of the patient by using a bandage to prevent the arm of the patient from being bent accidentally; not only is the binding process complicated and the fixing effect poor, but also the arm of the patient is bent due to improper operation in the binding process, and the blood circulation of the patient is not facilitated after long-time binding;

therefore, the brachial artery interventional puncture fixing device has important significance and practical value.

SUMMERY OF THE UTILITY MODEL

The device limits the bending of the arm through two sections of mutually connected combined devices, and the contact part of the device and the arm is prevented from excessively pressing the arm to influence the blood circulation through an elastic material;

in order to achieve the technical effects, the utility model is realized by the following technical scheme:

a brachial artery interventional puncture fixing device comprises: the air bag fixing device comprises an upper fixed die, a lower fixed die, an air bag, a fixing band and a supporting frame;

the lower fixed die is of an arc-shaped groove mounting structure, the upper fixed die is of an arc-shaped groove mounting structure with an opening in the middle, the upper fixed die and the lower fixed die are mutually spliced through a splicing structure, a fixed band is mounted on the lower fixed die, one end of the fixed band is connected with the lower fixed die, and connecting structures are arranged at two ends of the fixed band; the two ends of the upper fixed die are respectively provided with a semi-annular air bag, the end parts of the air bags are respectively connected with an inflating nozzle, and the inflating nozzles are communicated with the air bags; the supporting frame is arranged below the lower fixed die and comprises a front support and a rear support; the front bracket is hinged at the front end of the lower fixed die, and a limiting block is arranged at the hinged position; the rear bracket is hinged at the rear end of the lower fixed die, and the rear bracket is provided with a locking structure; an angle locking device is arranged at the hinged part of the rear bracket;

further, the support frame is of a T-shaped structure; the middle part of the rear bracket is provided with a telescopic structure;

furthermore, a buckle structure is arranged below the lower fixed die, and the support frame is connected with the lower fixed die through the buckle structure;

furthermore, a transparent protective cover is detachably connected to the opening of the upper fixed die;

further, the locking structure includes: a jackscrew and a knob; the jackscrew is in threaded connection with the telescopic structure of the rear bracket, and the knob is connected with the jackscrew;

furthermore, the inflating nozzle is of a one-way valve structure, and the inflating nozzle is detachably connected with the air bag;

compared with the prior art, the utility model has the beneficial effects that:

the device loads the arm of a patient to the middle through the connection of the upper and the lower fixed moulds through the positioning structure, and mutually pressurizes and fixes the upper and the lower fixed moulds through the binding band; the air bag is inflated to press the arm of the patient on the lower fixed die, so that the arm of the patient can be ensured to be tightly attached to the lower fixed die to keep the arm of the patient in a straightened state; compared with the existing device, the air bag is adopted to compress the arm to more conform to the shape of the arm of a patient, the fixing is more stable by adopting a compressing mode from top to bottom, and the defect that the existing hard device cannot enable the arm to be tightly attached is overcome;

because the upper arm of the patient is generally higher than the forearm when the arm is naturally placed, the patient cannot be naturally placed on a plane under the condition that the arm is straightened, and therefore, the patient is inconvenient to check and move; the device provides supports with different heights for the arms through the support frame, so that the arms of a patient can be placed in a more natural and comfortable posture;
