[0033] The right part of the two fixing rings 120 is fixedly connected with a first bandage 121; the left part of the two fixing rings 120 is fixedly connected with a second bandage 123; the two second bandages 123 are respectively aligned with the positions of the two first bandages 121; the top end surface of the two first bandages 121 is fixedly connected with a magic sub-paste 122; the bottom end surface of the two second bandages 123 is fixedly connected with a magic mother paste 124; the two magic mother pastes 124 are respectively aligned with the positions of the two magic sub-pastes 122.

[0034] The inside of the drip bottle 102 is fixedly connected with four flow guide ribs 127 in a ring array shape; the four flow guide ribs 127 are all trapezoidal block structures; the top and root of the four flow guide ribs 127 are provided with chamfers.

[0035] The inside of the drip bottle 102 is provided with a self-sealing ball 128; the self-sealing ball 128 is a spherical structure made of low-density medical plastic; the outside of the self-sealing ball 128 is fixedly connected with a sealing block 129; the sealing block 129 is a cylindrical structure made of medical-grade silicone; the sealing block 129 is aligned with the position of the medicine outlet of the drip bottle 102.

[0036] The outside of the infusion tube main body 1 is fixedly connected with a control air bag 125; the control air bag 125 is a flat circular structure made of medical-grade soft silicone; the air inlet of the control air bag 125 and the air outlet of the control air bag 125 are both provided with a one-way valve; the air outlet of the control air bag 125 is fixedly connected with a siphon pipe 126; the tail end of the siphon pipe 126 is fixedly connected to the upper part of the drip bottle 102.

[0037] The specific use and role of the embodiment are as follows: after the indwelling needle 106 is inserted into the patient, the medical staff can pull the auxiliary tear cloth 119 to tear the auxiliary adhesive tape 118 from the adhesive ring 117 to fix the indwishing needle 106, without the medical staff needing to additionally prepare the adhesive tape. After the indwishing needle 106 is fixed, the first bandage 121 and the second bandage 123 can be wrapped on the arm of the patient in a ring-shaped manner, and the magic son sticker 122 is adhered to the magic mother sticker 124 to fix the first bandage 121 and the second bandage 123, so as to further fix the infusion device through the first bandage 121 and the second bandage 123, enhance the adhesion of the indwishing needle 106 and the skin, and divide the drip bottle 102 into four independent flow guide channels through the setting of the flow guide ribs 127. After the medicine enters the drip bottle 102, the flow guide ribs 127 can divide the flow of the medicine, so that the medicine flows along the side of each flow guide rib 127 instead of impacting the inner wall or freely falling, thereby reducing the bubbles generated by the impact and turbulence. The flow of the medicine can be adjusted through the setting of the flow regulator 101. When the medicine gradually decreases, the liquid level in the drip bottle 102 continuously decreases, and the self-sealing ball 128 sinks synchronously with the liquid level due to the loss of buoyancy. When the liquid level is lowered to the level of the medicine outlet, the sealing plug 129 outside the self-sealing ball 128 is accurately aligned with and tightly adhered to the medicine outlet, completely blocking the medicine outlet. After the puncture needle 107 is inserted into the medicine bottle, there is no medicine in the drip bottle 102, the control air bag 125 is in a natural relaxation state, the inside is filled with air, the one-way valve at the air inlet is closed due to air pressure balance, and then the medical staff pinches the control air bag 125 to make the control air bag 125 deform and expel the air inside. After the hand is released, the control air bag 125 rebounds under the action of the silica gel elasticity, so that the inside of the control air bag 125 forms a transient negative pressure. The negative pressure is transmitted to the drip bottle 102 through the siphon pipe 126, so that the medicine in the medicine bottle is sucked into the drip bottle 102. The medicine slowly flows along the flow guide ribs 127 and gradually fills the bottom of the drip bottle 102. With the inflow of the medicine, the original air in the drip bottle 102 is squeezed and enters the rebounding control air bag 125 along the siphon pipe 126. At this time, the one-way valve at the air outlet of the control air bag 125 is opened, and the bubbles are brought into the bottom of the control air bag 125 with the air. When the medicine covers the root of the flow guide rib 127, the control air bag 125 has completed the rebounding. At this time, the air and a small amount of bubbles in the control air bag 125 are temporarily stored in the upper part of the control air bag 125.

[0040] The specific use and effect of the embodiment are as follows: in the initial state, the protective shell 110 shields the puncture needle 107, preventing the puncture needle 107 from scratching or stabbing the medical staff, when it is necessary to insert the puncture needle 107 into the medicine bottle to suck the medicine liquid, only need to push the control sliding block 115, the control sliding block 115 drives the guide sliding plate 114 to move, with the movement of the guide sliding plate 114, the locking plug 112 is driven to move and extrude the connecting spring 113, with the movement of the locking plug 112, the limiting of the protective shell 110 is removed, when the protective shell 110 shields the puncture needle 107, the control torsion spring 111 is in the torsion state, after the locking plug 112 removes the limiting of the protective shell 110, the protective shell 110 will be turned over with the rebound of the control torsion spring 111, and the puncture needle 107 is exposed.
