The complete use steps and the working principle of the invention are as follows:
first, the medical care professional can first place the base 45 on the patient bed near the wrist, and is fixed on the bed by utilizing the fixing surface 46 which is provided with a magic tape and is arranged on the bottom surface of the base 45, then the medical staff opens the wearing cavity ring 31 in opposite directions to facilitate the wearing cavity ring 31 to generate elastic deformation, and then the wearing cavity ring 31 is sleeved on the wrist of the patient, so as to limit the movement range of the wrist of the patient, then the hemispherical rod 41 at the bottom of the wearing cavity ring 31 is inserted into the magnetic seat 42 with the hole, because the lower end of the half-ball rod 41 is inserted into the magnetic seat 42 with holes and the magnetism of the half-ball rod 41 is opposite to that of the magnetic seat 42 with holes, the half-ball rod 41 can not be easily pulled out from the magnetic seat 42 with holes by the patient, thereby further limiting the moving range of the wrist and arm of the patient, meanwhile, because of the insertion connection mode of the half-club 41 and the magnetic seat with hole 42, the wrist of the patient can rotate in the band Kong Ci in a small range, thereby avoiding the discomfort of the arm of the patient caused by the long-time limitation of the wrist of the patient, and after the patient receives the puncture treatment of the indwelling needle, in the process that the wrist is limited, after the hemispherical rod 41 is accidentally pulled out from the magnetic seat with the hole 42, at this time, the displacement sensor 43 located outside the semi-ball rod 41 will detect the motion within the first time, and convert the motion into a control signal to be transmitted to the inside of the buzzer 44, the buzzer 44 will sound immediately when receiving the signal, so as to remind the patient that the arm cannot be moved easily and greatly, to avoid the accidental falling of the remaining needle or the damage to the blood vessel of the patient, meanwhile, the patient is reminded that the half ball rod 41 needs to be inserted back into the magnetic seat with the hole 42 in time, so that the safety of the device is improved;
when the semi-ball rod 41 is inserted into the magnetic seat 42 with the hole, the wearing cavity ring 31 is sleeved on the wrist of the patient, at this time, the medical staff repeatedly holds the air bag ball 35 and releases the air bag ball 35 to cause the air bag ball 35 to blow air, the blown air is led into the inner cavity of the wearing cavity ring 31 through the connecting valve port 33 along the air inlet pipe 34, after the air is gradually led into the inner cavity of the wearing cavity ring 31, the wearing cavity ring 31 gradually generates elastic deformation after the air is blown in, namely, the compression layer 32 gradually expands towards the wrist surface of the patient to generate compression force on the wrist of the patient, and after the wrist of the patient is subjected to pressure, the blood vessel on the upper surface of the palm of the patient is gradually shown, at this time, the medical staff can take the remaining needle to be inserted into the vein vessel of the patient, so that the medical staff can find the vein vessel of the patient in time, thereby facilitating the medical staff to perform the needle insertion work and further improving the work efficiency of the medical staff;
after the medical staff finishes puncturing the indwelling needle, the medical staff can firstly temporarily fix the indwelling needle part by using a medical adhesive strip, then the medical staff opens the valve 26, after the valve 26 is opened, the air in the inner cavity of the wearing cavity ring 31 can be guided into the fitting cavity plate 22 from the valve 26 through the air guide pipe 25 under the action of the rebound force of the pressing layer 32, after the air is gradually introduced into the fitting cavity plate 22, the fitting layer 23 positioned on the bottom surface of the fitting cavity plate 22 can also be elastically deformed and expanded downwards, and after the fitting layer 23 is expanded, the fitting layer can be directly attached downwards to the upper surface of the indwelling needle on the palm of the patient, at the moment, the medical staff can observe the compression tightness of the fitting layer 23 on the indwelling needle, and after the fitting layer 23 is enough to press and fix the indwelling needle stably, at the moment, the medical staff can close the valve 26 in time, so as to avoid that the attaching layer 23 is excessively expanded to cause excessive compression to the blood vessel at the palm of the patient, and meanwhile, after the attaching layer 23 is gradually compressed and attached to the upper surface of the palm of the patient, the adhesive area 24 at the outer edge of the bottom surface of the attaching layer 23 is automatically attached to the palm and the upper surface of the palm of the patient, so as to further fix the attaching layer 23 and the indwelling needle at the bottom of the attaching layer 23, the indwelling needle is compressed and fixed by introducing air into the attaching layer 23 to expand, and the auxiliary fixation is performed by using the circle of adhesive area 24 at the outer edge of the bottom surface of the attaching layer 23, so that the large-area covering and fixing of the indwelling needle is met, and the attaching surface of the adhesive area 24 is only a circle at the outer edge, therefore, when the indwelling needle needs to be taken down by the medical staff, the connection between the valve port 33 and the air inlet pipe 34 is only required to be disconnected, and the valve port 33 is manually opened, the indwelling needle can be simply and quickly removed by releasing air in the fit cavity plate 22, and compared with the existing mode of directly covering by using a transparent application patch, the mode further improves the speed of fixing the indwelling needle on the premise of not influencing the stability of the indwelling needle, is convenient for medical personnel to remove the indwelling needle, and can reduce the pain of a patient in the process of removing the indwelling needle;
in addition, through setting up at arc breach board 1 and wearing the connecting plate 12 that sets up between the chamber ring 31, this connecting plate 12 is close to one side of arc breach board 1 and is hinge structure, and the turned angle that hinge structure restricted is less than thirty degrees, with this avoid the patient to use this device after, patient's wrist activity range is too big and cause the condition that the needle appears becoming flexible to keep somewhere, leave not less than ten centimetres vertical interval between 12 left end of connecting plate and the arc breach board 1 in addition, with this provide can carry out the space of puncture needle work to the patient in this interval in medical personnel.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
