Description

DSA machine ray imprisoned safe cabin in coronary intervention

technical field

The utility model relates to a medical device, in particular to a DSA machine ray confinement safe cabin in coronary artery intervention.

Background technique

During coronary intervention, it is necessary to puncture and place a catheter from the radial artery or right femoral artery of the patient's right arm, and then use an angiography or treatment catheter to extend along the blood vessel to the heart to implant a stent or inject thrombolytic drugs. It needs to be used continuously during the operation The C-arm machine (DSA machine) emits X-rays to the patient's heart for search guidance, and uses contrast agents to determine the lesion and determine the effect of the operation.

Continuous ray radiation will cause serious adverse consequences such as carcinogenesis, teratogenicity, eye cataracts, decreased immunity, and thyroid diseases to the irradiated personnel. At present, in coronary artery intervention, there is no unilateral closed barrier protection measure to isolate radiation, only one-sided protection such as lead screen and lead clothing is used to protect the interventional medical personnel, and the patient does not have any shielding protection, except for the heart. The rest of the body will also be radiated by scattered rays, and the existing radiation protection technology has a greater potential safety hazard for the health of doctors, nurses and patients.

One end of the cavity B is provided with an opening B, and the opening B faces the opening A, and the torso The outer cover 2 is provided with an insertion operation port 20 at the side near one end of the head outer cover 3 (the patient's right forearm or right femoral artery is exposed through the insertion operation port, which is convenient for tube placement), and the trunk outer cover 2 and The head cover 3 is arranged at intervals, and a vacancy zone 6 is provided between the two (the vacancy zone exposes the patient's heart region, does not contain lead material, and is convenient for the DSA machine to carry out radiation exploration).

The head cover 3 is movably installed on the upper end of the front part of the bed body 1, and a cavity A capable of accommodating the head is formed between it and the bed body 1, and an opening A is provided at one end of the cavity A. Head cover 3 comprises left half shell 31, right half shell 32, bottom shell 33 and rotating shaft B34; Respectively movably installed on the rotating shaft B34, and located at the upper end of the bottom shell 33, the left half shell 31 and the right half shell 32 can rotate around the rotating shaft B34 respectively, so that the cavity A is opened or closed at the upper end, the left half shell 31 and the right half shell 32 when turning back (ie the direction away from each other), the cavity A is gradually opened at the upper end, and when the left half shell 31 and the right half shell 32 rotate towards each other (ie the direction close to each other), the cavity A is gradually closed at the upper end.

The upper isolation seat 4 is located at the upper end of the torso cover 2 close to the head cover 3, and is vertically arranged along the width direction of the bed body 1, thereby separating the vacancy zone 6 from the torso cover 2.

Preferably, the torso cover 2 includes three sub-covers, the three sub-covers are nested sequentially in increasing order of size, and any two adjacent sub-covers in the three sub-covers can slide relative to each other, thereby making the length of the entire torso cover 2 longer or shorter. Correspondingly, the bed body 1 is provided with three sets of chute (not shown in the figure), and the three sets of chute are respectively matched with the three sub-covers, and each set of chute includes two chute extending along the length direction of the bed 1 The two chutes included in one set of chutes are arranged on both sides in the width direction of the bed body 1; During the relative sliding process of the adjacent sub-covers, the lower edges on both sides of the sub-covers slide simultaneously in a set of chute matched with the sub-covers.

Preferably, the trunk cover 2 is provided with a conduit groove 21 extending along its length and passing through three sub-covers. One end of the conduit groove 21 is connected to the insertion operation port 20, and the other end is connected to the rear edge of the trunk cover 2, and the conduit groove The groove bottom of 21 does not penetrate into cavity B. Catheter groove 21 is used for arranging the catheter for operation.

Preferably, the upper end of the upper isolation seat 4 is provided with an upper plate 41, and the upper plate 41 is movably mounted on the upper end of the upper isolation seat 4 through a rotating shaft, which can rotate relative to the upper isolation seat 4 and be fixed by friction. Its reversible design prevents it from limiting the operating range of the C-arm crane.

Preferably, the rear end of the bed body 1 is provided with a placement cabinet 13, and the placement cabinet 13 is provided with a drug placement layer and an apparatus placement layer (for placing a defibrillator and a micropump), and the top of the placement cabinet 13 is provided with a lead equivalent of 0.5mm. Transparent lead glass, the lower part is provided with a lead skin with a lead equivalent of 0.5mm.

Briefly describe the application of the present utility model: in coronary artery intervention, the DSA machine ray confinement safety cabin (hereinafter referred to as the safety cabin) is a unilateral closed barrier for radiation protection around the DSA machine and the treatment bed, and the inside of the safety cabin is provided with a patient The ray shielding device for non-surgical parts (i.e., the torso cover and the head cover) can confine the scattered rays in PCI (coronary intervention) in the DSA exposure area without affecting the operation and use of the machine.

The trunk cover 2 and the head cover 3 are arranged at intervals, and a vacancy zone 6 is arranged between the two. The setting of the vacancy zone 6 does not affect the ray projection of the part above the navel of the patient. Any two adjacent sub-covers in the three sub-covers of the torso cover 2 The outer cover can slide relatively, and then the length of the whole trunk outer cover 2 is elongated or shortened. When the trunk outer cover 2 is elongated, the vacancy band 6 becomes narrower. The length of the trunk outer cover 2 is adjusted adaptively.

The cavity B formed between the trunk cover 2 and the bed body 1 has a height of 40 cm, which is enough to accommodate the thickness of the trunks of patients of various sizes. When the DSA machine turns upward toward the isolation seat, in order to prevent the ray emitting tube of the DSA machine from colliding with the upper isolation seat, the upper plate of the upper isolation seat can be rotated and tilted around the rotation axis. The maximum inclination angle is 45°. The upper plate is made of transparent The lead equivalent of 1mm is made of lead glass material, and the thickness is 2cm, so that doctors can observe the angle, position and patient condition of the DSA machine tube. Made of lead. Holes (not shown) are arranged around the torso cover, so as to facilitate the operation of doctors, the input of liquids by nurses, and the connection of instruments such as ECG monitoring and electric defibrillation.

The left half-shell 31 and the right half-shell 32 of the head cover 3 are made of lead glass with a lead equivalent of 1 mm and a thickness of 2 cm, so that the medical staff can observe the patient's complexion and breathing. Except for the direction of the head end of the bed body 1, lead skins with a lead equivalent of 0.5 mm are hung on the other sides between the bed body 1 and the ground. The lead skin height is 100 cm, which can avoid the lead skin when the bed body 1 falls to the lowest The impact on the movement of the bed body 1 will protect the radiation-sensitive organs other than the heart to the greatest extent, so that the radiation is confined outside the safety cabin, protecting the whole body of doctors and nurses, and protecting the non-examination organs of patients from radiation hazards.
