Example 1

The invention provides an intelligent PICC (peripherally inserted central catheter) catheter arm sterilizer, which comprises a sterilizing box 1, wherein a sterile inner chamber 10 is formed in the sterilizing box 1, a sterile sleeve automatic arm sleeving mechanism 2 is installed on the right side of the sterile inner chamber 10, the sterile sleeve automatic arm sleeving mechanism 2 comprises a circular ring 24, connecting plates 22 are symmetrically welded on the outer walls of two sides of the circular ring 24, an electric push rod 23 is installed above the connecting plates 22, a through hole 240 is formed in the position, close to the end part of a piston rod of the electric push rod 23, of the circular ring 24, a first sliding block 20 and a second sliding block 25 are respectively arranged at the end parts, far away from the circular ring 24, of the two connecting plates 22, a screw rod 21 is screwed on the first sliding block 20, a guide rod 26 is slidably connected on the second sliding block 25, a sleeve arm guide rail 11 is arranged in the sterilizing box 1 and close to the screw rod 21 and the guide rod 26, a sterile sleeve arm bag cabin 12 is arranged on the left side of the sterile sleeve automatic arm sleeving mechanism 2, the interior of the sterile inner chamber 10 is communicated with the interior of the sterile arm bag cabin 12, sterile sleeve boxes 3 are arranged inside the sterile arm sleeve bag bin 12, sterile sleeves 4 are arranged inside the sterile sleeve boxes 3, bonding areas 40 are symmetrically arranged on two sides of the inner wall of the end portion of each sterile sleeve 4, and a disinfection spray head 5 is arranged at the position, close to the right side, of the top of the sterile inner cabin 10.

In this embodiment, the inside left position integrated into one piece that is close to of aseptic inner chamber 10 has arm to hold in the palm 100 for support patient's arm, prevent the arm and the aseptic inner chamber 10 bottom contact, be not convenient for follow-up aseptic cover 4 of arm cover, aseptic inner chamber 10 is close to the right side and has seted up sealed entry 13, and the patient of being convenient for inserts the arm inside aseptic inner chamber 10.

The end of the piston rod of the electric push rod 23 is welded with an arc-shaped plate 230, and the arc-shaped plate 230 has a radian, so that the sterile sleeve 4 can be conveniently fixed on the arm in the following process.

Further, the diameter of the piston rod of the electric push rod 23 is smaller than the diameter of the through hole 240, when the electric push rod 23 is turned on, the piston rod of the electric push rod 23 can extend through the through hole 240, and the sterile sleeve 4 is pushed, so that the sterile sleeve 4 is adhered to the arm of the patient through the adhesion area 40, and the sterile sleeve 4 is fixed to the arm of the patient.

In the actual process, the outer diameter of the sterile sleeve box 3 is matched with the outer diameter of the circular ring 24, and the circular ring 24 is in bonding fit with the sterile sleeve 4, so that the sterile sleeve 4 in the sterile sleeve box 3 can be conveniently pulled out through the circular ring 24.

The first slider 20 is provided with a threaded hole at a position close to the screw rod 21, and when the screw rod 21 rotates, the first slider 20 moves along the outer wall of the screw rod 21 by acting force generated by matching the threads on the inner wall of the threaded hole and the threads on the screw rod 21.

The second slider 25 is provided with a guide rod hole at a position close to the guide rod 26, and the second slider 25 can move along the outer wall of the guide rod 26.

In addition, the end part of the screw rod 21 is provided with a stepping motor, an output shaft of the stepping motor is fixedly connected with the screw rod 21 through a coupler, and when the power supply of the stepping motor is switched on, the screw rod 21 can be driven to rotate through the output shaft of the stepping motor.

It is worth explaining that the disinfection shower nozzle 5 is externally connected with a liquid storage tank for providing disinfectant, the liquid storage tank is provided with a water pump, when the arm enters the sterile inner chamber 10, the water pump is started, the disinfectant in the liquid storage tank is extracted by the water pump, and the disinfectant is sprayed onto the arm of the patient through the disinfection shower nozzle 5 (the sludge of the arm can be removed by the acting force sprayed by the disinfection shower nozzle 5) to disinfect the arm of the patient.

The present invention relates to circuits and electronic components and modules all of which are known in the art and are fully implemented by those skilled in the art, and it is not necessary to state that the invention is intended to be limited to such modifications as are suited to the particular use contemplated.

It is to be added that the sterilization zone is: the distance between the forearm and the elbow joint is 10-15cm, and the distance between the forearm and the elbow joint is the starting point and the distance between the shoulder joint and the shoulder joint is the ending point. The disinfection spray nozzle 5 needs to meet the requirements of disinfection by back and forth movement and disinfection around arms for one circle. The sealing port 13 needs to be adjusted to be clamped to the shoulder joint, so that the medical staff is prevented from touching the non-sterile area in the process of placing the tube. A disinfectant waste storage box (not shown) can be added between the sealing port 13 and the arm mop 100, and can be taken out for disposal.

In the specific implementation process, in order to disinfect the arm of a patient, firstly, the water pump is started, disinfectant in the liquid storage tank is pumped by the water pump, the disinfectant is sprayed onto the arm of the patient through the disinfection spray head 5 to disinfect the arm of the patient, then, the power supply of the stepping motor is switched on, the lead screw 21 is driven to rotate through the output shaft of the stepping motor, the lead screw 21 is screwed with the first slide block 20 to generate acting force, the first slide block 20 moves along the outer wall of the lead screw 21, further, the second slide block 25 is driven to move along the outer wall of the guide rod 26 through the connecting plate 22 and the circular ring 24, at the moment, the sterile sleeve 4 in the sterile sleeve box 3 is pulled out through the circular ring 24, the sterile sleeve 4 is sleeved on the arm of the patient, the disinfection of the arm of the patient is realized, the disinfection and sterilization effects can be achieved, and when the disinfection is stopped, the sterile sleeve on the arm of the patient can ensure that the disinfected skin is not polluted, the operation of operators and assistants is not needed, the manpower resource is saved, and the skin of the patient can be prevented from being damaged.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
