[0023] Preferably, the method for using the medical syringe device comprises the following steps:

[0024] S1: When the device is in use, the syringe rod box, the syringe barrel box and the collection box are first installed on the cylindrical cover, and at this time, the syringe rod in the syringe rod box and the syringe barrel in the syringe barrel box are both dropped into the uppermost placement groove, and then the T-shaped rod is pressed to drive the rotating gear to move right and roll on the fixed tooth plate, push the sliding tooth plate to move right, push the syringe rod into the syringe barrel, and complete the assembly of the syringe rod and the syringe barrel;

[0025] S2: Then, under the action of the reset force of the reset spring, the T-shaped pressure rod is driven to move left and reset, and during the reset process of the T-shaped pressure rod, the right pressure sleeve is driven to move left. When the right pressure sleeve moves left and contacts the end face of the turntable, it pushes the turntable to move left. At this time, the protrusion on the turntable moves left in the transverse groove, and when the protrusion moves left, it squeezes the beveled surface of the spring compression block, driving the limit tube to rotate clockwise, so that the protrusion passively enters the guide groove, and the limit tube is driven to rotate sixty degrees clockwise by the sliding of the protrusion in the guide groove, and at the same time, the assembled syringe pressure rod and syringe pressure cylinder in the rotating cylinder are driven to rotate sixty degrees with the cooperation of the connecting rod;

[0026] Then the user presses the T-shaped pressure rod again to push the first L-shaped tooth plate to move rightward and squeeze the deflection plate to deflect, so that the inverted T-shaped push plate squeezes the arc push plate to move rightward, pushing the syringe barrel to move rightward after rotating sixty degrees, causing the barrel mouth of the syringe barrel to squeeze the sealing block at the right end of the syringe barrel to move rightward and conflict with the pipe mouth of the docking tube, completing the docking of the syringe barrel and the docking tube;

[0027] As the first L-shaped tooth plate continues to move right, the transmission gear rotates clockwise, which in turn drives the second L-shaped tooth plate to move left, pulling the syringe pressure rod to move left, and sucking the saline in the medicine box into the syringe pressure barrel;

[0028] S3: Then the T-shaped pressure rod is reset again under the action of the reset force of the reset spring, and drives the syringe cylinder for inhaling the medicine to rotate sixty degrees again, and under the action of the guide bar limiting, the right end of the syringe cylinder after rotation is ensured to abut in the annular opening, and the right end of the syringe cylinder abuts on the right end of the second spring telescopic plate, limiting the syringe cylinder to prevent it from moving left and right;

[0029] Then, after the user installs the needle on the right end of the syringe barrel, he presses the T-shaped pressure rod to move left, so that the arc-shaped clamping plate on the T-shaped pressure rod squeezes the left end of the syringe pressure rod and drives the first spring telescopic plate to compress, and then the pressure of the syringe pressure rod is clamped by the first spring telescopic plate and the arc-shaped clamping plate. At this time, as the first spring telescopic plate continues to move right, the syringe pressure rod is pushed to slide in the syringe barrel, and after exhaust treatment, the needle is inserted into the medicine bottle to achieve mixing of physiological saline and medicine;

[0030] S4: When the drug injection is completed, the first spring telescopic plate drives the L-shaped elastic plate to move right and snap into the inner plate of the second spring telescopic plate, and then resets as the T-shaped pressure rod moves left, driving the first spring telescopic plate to move left, so that the arc-shaped card plate pulls the left end of the syringe pressure rod to move left, while the inner plate of the second spring telescopic plate is compressed by the left movement of the L-shaped elastic plate, thereby releasing the resistance force of the second spring telescopic plate on the left end face of the syringe cylinder. At this time, the syringe cylinder follows the syringe pressure rod to move left in the placement groove, and the protrusion on the turntable cooperates with the guide groove to drive the limiting tube and the rotating cylinder to rotate sixty degrees clockwise again, so that the used syringe pressure rod, syringe pressure barrel and needle fall into the collection box.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, by pressing the T-shaped pressure rod, the rotating gear is driven to move right and roll on the fixed tooth plate, the sliding tooth plate is pushed to move right, and the syringe pressure rod is pushed into the syringe pressure barrel to complete the assembly of the syringe pressure rod and the syringe pressure barrel. The operation is simple and convenient.

[0033] In the present invention, the user presses the T-shaped pressure rod to move right again, so that the barrel mouth squeezing sealing block at the right end of the syringe barrel moves right and conflicts with the pipe mouth of the docking tube. After the syringe barrel and the docking tube are docked, the first L-shaped tooth plate continues to move right, driving the transmission gear to rotate clockwise, thereby driving the second L-shaped tooth plate to move left, pulling the syringe pressure rod to move left, and sucking the saline in the medicine box into the syringe barrel for drug suction processing, which is convenient for medical staff to quickly inject the saline into the corresponding medicine bottle later, reducing the fatigue of medical staff.

[0034] In the present invention, after the user installs the needle on the right end of the syringe barrel, he presses the T-shaped pressure rod to move left, so that the arc-shaped clamping plate on the T-shaped pressure rod squeezes the left end of the syringe pressure rod and drives the first spring telescopic plate to be compressed, and the syringe pressure rod is clamped by the first spring telescopic plate and the arc-shaped clamping plate. At this time, as the first spring telescopic plate continues to move right, the syringe pressure rod is pushed to slide in the syringe barrel. After exhaust treatment, the needle is inserted into the medicine bottle to achieve mixing of physiological saline and medicine, thereby ensuring the work efficiency of medical staff.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figures 1 to 12 The present invention provides a technical solution: a medical syringe device, comprising a cylindrical cover shell 1, and the cylindrical cover shell 1 is transparent plastic, a syringe pressure rod box 2 is clamped on the outer side of the cylindrical cover shell 1, a syringe pressure barrel box 3 is arranged on the right side of the syringe pressure rod box 2, and the syringe pressure barrel box 3 is clamped on the cylindrical cover shell 1, and a guide strip 12 is fixedly connected to the right side of the inner wall of the cylindrical cover shell 1; the syringe pressure rod box 2, the syringe pressure barrel box 3 and the collection box 4 can all be removed from the cylindrical cover shell 1.

[0050] A collecting box 4 is also provided on the outer side of the cylindrical cover shell 1, and the collecting box 4 is directly below the syringe pressure rod box 2 and the syringe pressure barrel box 3. An annular opening 5 is provided on the right end cover of the cylindrical cover shell 1. The right end cover of the cylindrical cover shell 1 is buckled on the cylindrical cover shell 1 and can be removed. The right end cover of the cylindrical cover shell 1 is clamped on the right end of the cylindrical cover shell 1, which is convenient for removing the right end cover of the cylindrical cover shell 1 from the right side of the cylindrical cover shell 1. A T-shaped pressure rod 6 is movably inserted on the left end surface of the cylindrical cover shell 1, and a rotating feeding mechanism 7 is movably sleeved on the right end of the T-shaped pressure rod 6; a limiting horizontal bar is fixedly connected to the outer side of the cross bar of the T-shaped pressure rod 6.

[0051] The rotary feeding mechanism 7 includes a sleeve 71 movably sleeved on the right end of the T-shaped pressure rod 6, a connecting plate 72 is fixedly connected to the right end of the side of the sleeve 71, a disc 73 is fixedly connected to the right end of the connecting plate 72, and a return spring 717 is fixedly connected between the disc 73 and the right end of the T-shaped pressure rod 6, an L-shaped connecting plate 74 is fixedly connected to the side of the disc 73, and one end of the L-shaped connecting plate 74 away from the disc 73 is fixed to the inner wall of the cylindrical cover 1;

[0052] The right end of the disc 73 is overlapped with a medicine box 75. The medicine in the medicine box 75 is physiological saline. The medicine box 75 is regularly disinfected or replaced, and the physiological saline is input into the medicine box 75 under a sterile environment.

A compression spring 78 is fixedly connected to the sealing block 77, and the end of the compression spring 78 away from the sealing block 77 is fixed to the inner wall of the docking pipe 76.

[0053] It should be noted that the application scenario of the device is such as an infusion station. During the flu period, a large number of people need infusions. Most of the therapeutic drugs used are the same, but some drugs need to be injected with saline solution for mixing before they can be used later. Therefore, for this scenario, it is necessary to frequently use a syringe to extract saline solution and inject it into multiple medicine bottles;

[0054] After the sealing block 77 is squeezed to the right by the barrel mouth at the right end of the syringe cylinder, it clashes with the tube mouth of the docking tube 76. At this time, the right end of the syringe cylinder clashes with the M-shaped convex strip on the arc surface of the sealing block 77, so that a gap is generated between the right end of the syringe cylinder and the M-shaped convex strip of the sealing block 77, which is convenient for subsequent inhalation of the drug solution. Then the user pulls the syringe pressure rod to move left to suck the physiological saline in the medicine box 75 into the syringe cylinder, thus completing the device's absorption of the drug solution; achieving the mixing of the drugs, ensuring the efficiency of the medical staff's work, and reducing the user's fatigue.

[0059] An inverted T-shaped push plate 83 is hinged at the upper ends of the two deflection plates 81. The inverted T-shaped push plate 83 abuts against the lower side of the first L-shaped tooth plate 713. The inverted T-shaped push plate 83 abuts against an arc-shaped push plate 84.

Therefore, the user presses the T-shaped pressure rod 6 to move left, and clamps the pressure of the syringe pressure rod through the first spring expansion plate 92 and the arc-shaped clamping plate 93. At this time, as the first spring expansion plate 92 continues to move right, the syringe pressure rod is pushed to slide in the syringe pressure barrel. After exhaust treatment, the needle is inserted into the medicine bottle to inject physiological saline into it. The amount of sliding of the syringe pressure rod in the syringe pressure barrel is observed through the transparent cylindrical cover 1, and the scale on the syringe pressure barrel is referred to to increase the concentration of the physiological saline according to demand to ensure the efficiency of the medical staff's work.

At this time, the protrusion 109 on the turntable 103 moves left in the transverse groove 106, and when the protrusion 109 moves left, it squeezes the beveled surface of the spring compression block 108, driving the limit tube 104 to rotate clockwise, so that the protrusion 109 passively enters the guide groove 107, and the protrusion 109 slides in the guide groove 107 to drive the limit tube 104 to rotate sixty degrees clockwise, and with the cooperation of the connecting rod 102, the assembled syringe pressure rod and syringe pressure cylinder in the rotating cylinder 101 are driven to rotate sixty degrees at the same time;

[0075] Then the user presses the T-shaped pressing rod 6 again to push the first L-shaped tooth plate 713 to move rightward, and squeezes the deflection plate 81 to deflect, so that the inverted T-shaped pushing plate 83 squeezes the arc-shaped pushing plate 84 to move rightward, pushing the syringe barrel to move rightward after rotating sixty degrees, and causing the barrel mouth of the syringe barrel to squeeze the sealing block 77 at the right end of the syringe barrel to move rightward and conflict with the pipe mouth of the docking tube 76, completing the docking of the syringe barrel and the docking tube 76;

[0076] As the first L-shaped toothed plate 713 continues to move rightward, the transmission gear 714 is driven to rotate clockwise, thereby driving the second L-shaped toothed plate 715 to move leftward, pulling the syringe pressing rod to move leftward, and sucking the physiological saline in the medicine box 75 into the syringe pressing cylinder;

[0077] S3: Then the T-shaped pressure rod 6 is reset again under the action of the reset force of the reset spring 717, and drives the syringe cylinder for inhaling medicine to rotate sixty degrees again, and under the action of the limiting action of the guide bar 12, the right end of the syringe cylinder after rotation is ensured to abut in the annular opening 5, and the right end of the syringe cylinder abuts on the right end of the second spring expansion plate 95, limiting the syringe cylinder to prevent it from moving left and right;

[0078] Then, after the user installs the needle on the right end of the syringe barrel, he presses the T-shaped pressure rod 6 to move left, so that the arc-shaped clamping plate 93 on the T-shaped pressure rod 6 squeezes the left end of the syringe pressure rod and drives the first spring expansion plate 92 to be compressed. The pressure of the syringe pressure rod is clamped by the first spring expansion plate 92 and the arc-shaped clamping plate 93. At this time, as the first spring expansion plate 92 continues to move right, the syringe pressure rod is pushed to slide in the syringe barrel. After exhaust treatment, the needle is inserted into the medicine bottle to achieve mixing of physiological saline and medicine.

[0079] S4: When the drug injection is completed, the first spring expansion plate 92 drives the L-shaped elastic plate 94 to move right and snap into the inner plate of the second spring expansion plate 95, and then resets with the left movement of the T-shaped pressure rod 6, driving the first spring expansion plate 92 to move left, so that the arc-shaped clamping plate 93 pulls the left end of the syringe pressure rod to move left, and at the same time, the inner plate of the second spring expansion plate 95 is compressed by the left movement of the L-shaped elastic plate 94, thereby releasing the resistance of the second spring expansion plate 95 to the left end surface of the syringe cylinder. At this time, the syringe cylinder follows the syringe pressure rod to move left in the placement groove 105, and the protrusion 109 on the turntable 103 cooperates with the guide groove 107 to drive the limiting tube 104 and the rotating cylinder 101 to rotate sixty degrees clockwise again, so that the used syringe pressure rod, syringe pressure cylinder and needle fall into the collection box 4;

[0080] Through the cyclic operation of the above device, it is convenient for the user to inject physiological saline into the medicine bottle.
