[0012] A method for using a venous therapy anti-dislocation fixation device is also provided, which is used to operate a venous therapy anti-dislocation fixation device, comprising the following steps:

[0013] S1: After the infusion needle is inserted into the infusion bottle, the fixing ring and the groove are put on the outside of the infusion bottle and the infusion needle to restrict the infusion bottle and the infusion needle;

[0014] S2: When replacing the infusion bottle, first pinch the two sets of anti-slip strips and rotate the fixed ring to flip down. After flipping down the fixed ring, the infusion needle can be directly pulled out from the infusion bottle;

[0015] S3: When changing the infusion needle, the rotating movable frame will squeeze the semicircular balls on both sides, and pushing the two sets of clamps will squeeze the infusion tube on the lower side of the infusion needle to block the entry of outside air.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the infusion needle is inserted into the infusion bottle, the fixing ring and the groove are put on the outside of the infusion bottle and the infusion needle. After the two groups of clamping blocks contact the bottleneck of the infusion bottle, they shrink and move toward the two groups of movable grooves, and at the same time squeeze the two groups of springs until the bottleneck of the infusion bottle moves to the inside of the bottleneck sleeve. The two groups of clamping blocks are respectively clamped on the outside of the bottleneck of the infusion bottle and clamped on the upper side of the bottleneck ring. Then the groove is put on the outside of the disc support. After the two groups of arc-shaped spring pieces are stretched open by the disc support and enter the groove, the deformed two groups of arc-shaped spring pieces rebound to limit the outside of the disc support, thereby completing the restriction of the infusion bottle and the infusion needle, preventing the infusion needle from being separated from the infusion bottle when the infusion tube is pulled, affecting the patient's treatment.

[0018] 2. When replacing the infusion bottle, you can first pinch the two groups of anti-slip strips to make the two groups of positioning springs close together and deform, and separate the limiting card strip 1 on the positioning spring from the limiting card strip 2 on the support sleeve, so that the fixing ring and the two groups of support sleeves and the support rod can be rotated along the fixing nails respectively, and the two groups of resistance shafts produce rotational damping for the rotating two groups of support rods to prevent the turned-down fixing ring from moving randomly. After turning down the fixing ring, the infusion needle can be directly pulled out from the infusion bottle, and then inserted into another infusion bottle. Pinch the two groups of pressure blocks to rotate the fixing ring and then clamp it at the bottleneck of the infusion bottle to complete the positioning purpose, release the pressure blocks, and the limiting card strip 1 will mesh with the limiting card strip 2 again to limit the horizontal support rod and the support sleeve, prevent the support sleeve from rotating and being pulled downward, and achieve the anti-slip effect.

[0019] 3. Each time the infusion needle is inserted into the infusion bottle to a different depth, the horizontal support rod can be directly pushed upward. With the elastic characteristics of the two sets of positioning springs, the horizontal support rod and the two sets of positioning springs move upward to quickly complete the distance between the horizontal support rod and the fixed ring, which is adapted to the different depths of the infusion needle inserted into the infusion bottle.

[0020] 4. Each time the infusion needle is changed, the two sets of support rods that are rotated down drive the two sets of arc-shaped bars and the movable frame to rotate forward respectively. The inclined positions on the sides of the movable frame squeeze the two semi-spheres on both sides respectively. The two movable rods drive the two clamping blocks to slide closer, while squeezing the two springs II at the same time. The two clamping blocks that are closer will squeeze the infusion tube under the infusion needle, so as to cut off the outside air when the infusion needle is pulled out, reduce the air flowing into the infusion tube, and prevent discomfort to the patient.

Detailed implementation mode

[0030] In order to more clearly understand the above - mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0032] As Figures 1 to 8 shown, a kind of anti - detachment and fixation device for intravenous therapy includes an infusion bottle 1. A bottleneck ring 2 is fixedly arranged at the lower bottleneck of the infusion bottle 1. An infusion needle 3 is inserted into the lower side of the infusion bottle 1. A tray 4 is fixedly arranged on the outer side of the infusion needle 3. An anti - detachment component 5 is arranged on the outer sides of the infusion bottle 1 and the tray 4. A partition component 6 is arranged on the lower side of the anti - detachment component 5. The anti - detachment component 5 includes a horizontal support rod 51 sleeved on the outer side of the tray 4. Positioning elastic pieces 52 are fixedly arranged at the upper ends of both sides of the horizontal support rod 51. A number of groups of limiting bars one 53 are fixedly arranged at the opposite ends of the two groups of positioning elastic pieces 52. Pressing blocks 54 are fixedly arranged at positions near the upper side of the front ends of the two groups of positioning elastic pieces 52. Anti - slip strips 55 are fixedly arranged at the opposite ends of the two groups of pressing blocks 54. Fixing pieces 56 are fixedly arranged at both ends of the horizontal support rod 51. Fixing nails 57 are fixedly arranged at the opposite ends of the two groups of fixing pieces 56. Resistance rotating shafts 58 are arranged on the outer sides of the two groups of fixing nails 57. Support rods 59 are rotatably arranged at positions between the outer sides of the two groups of fixing nails 57 near the resistance rotating shafts 58 and the fixing pieces 56. Movable openings 510 are respectively formed on the inner sides of the two groups of support rods 59. Support sleeves 511 are movably sleeved on the upper sides of the two groups of support rods 59. A number of groups of limiting bars two 512 are fixedly arranged at one ends of the two groups of support sleeves 511 corresponding to the positioning elastic pieces 52. Fixing blocks 513 are respectively fixedly arranged at positions near the lower sides inside the two groups of support sleeves 511.

[0033] The positioning elastic piece 52 is plastic. The upper sides of several groups of limiting card strips 53 are all set as arc-shaped surfaces. The pressing block 54 and the positioning elastic piece 52 are of an integral structure. The fixing piece 56 and the transverse support rod 51 are of an integral structure. The resistance rotating shaft 58 is damped between the support rod 59 and one side of the fixing nail 57. The support rod 59 is sleeved on the outside of the fixing block 513. The movable opening 510 is adapted to the fixing block 513. The lower sides of several groups of limiting card strips 512 are set as arc-shaped surfaces. Several groups of limiting card strips 512 and several groups of limiting card strips 53 are meshed.

[0034] When replacing the infusion bottle, two groups of anti-slip strips 55 can be pinched first to make the two groups of positioning elastic pieces 52 approach and deform. The limiting card strips 53 on the positioning elastic piece 52 are separated from the limiting card strips 512 on the support sleeve 511, and then the fixing ring 514 and the two groups of support sleeves 511 and the support rods 59 can be rotated along the fixing nails 57 respectively. The two groups of resistance rotating shafts 58 generate rotational damping for the two groups of rotating support rods 59 to prevent the flipped fixing ring 514 from moving randomly. After flipping down the fixing ring 514, the infusion needle 3 can be directly pulled out from the infusion bottle 1. When inserting it into another infusion bottle 1, pinch the two groups of pressing blocks 54 to rotate the fixing ring 514 and then clamp it at the bottleneck of the infusion bottle 1 to complete the positioning purpose. Release the pressing block 54, and the limiting card strip 53 meshes with the limiting card strip 512 again to restrict the transverse support rod 51 and the support sleeve 511, prevent the support sleeve 511 from rotating and being pulled downward, and achieve the anti-detachment effect. Since the depth of the infusion needle 3 inserted into the infusion bottle 1 is different each time, the transverse support rod 51 can be directly pushed upward. With the elastic characteristics of the two groups of positioning elastic pieces 52, the transverse support rod 51 and the two groups of positioning elastic pieces 52 move upward, quickly completing the distance between the transverse support rod 51 and the fixing ring 514 to adapt to the different depths of the infusion needle 3 inserted into the infusion bottle 1.

[0035] Two groups of fixing rings 514 are fixedly arranged at the upper ends of the two groups of support sleeves 511. A bottleneck sleeve 515 is fixedly arranged inside the fixing ring 514. Activity slots 516 are respectively opened at the positions near the front sides inside both sides of the fixing ring 514. Clamping blocks 517 are slidably arranged inside the two groups of activity slots 516. Two groups of springs 518 are fixedly arranged between the two groups of clamping blocks 517 and the inner walls of the two groups of activity slots 516. Push blocks 519 are fixedly arranged on both sides of the fixing ring 514. Grooves 520 are opened at the positions corresponding to the disc tray 4 on the inner side of the transverse support rod 51. Arc-shaped elastic pieces 521 are fixedly arranged at the positions near the front sides on both sides of the groove 520.

[0036] The bottleneck sleeve 515 is sleeved on the bottleneck of the infusion bottle 1 near the upper side of the bottleneck ring 2. The two groups of clamping blocks 517 clamp the bottleneck of the infusion bottle 1. The two groups of push blocks 519 and the fixing ring 514 are of an integral structure. The groove 520 is sleeved on the outside of the disc tray 4. The two groups of arc-shaped elastic pieces 521 expand towards both sides respectively.

[0037] After the infusion needle 3 is inserted into the infusion bottle 1, the fixing ring 514 and the groove 520 are sleeved outside the infusion bottle 1 and the infusion needle 3. After the two groups of clamping blocks 517 contact the bottleneck of the infusion bottle 1, they contract and move towards the two groups of movable grooves 516, while squeezing the two groups of first springs 518. Until the bottleneck of the infusion bottle 1 moves to the inside of the bottleneck sleeve 515, the two groups of clamping blocks 517 are respectively clamped outside the bottleneck of the infusion bottle 1, at the upper side position of the bottleneck ring 2. Then the groove 520 is sleeved towards the outside of the tray 4. After the two groups of arc-shaped elastic pieces 521 are propped open by the tray 4 and enter the groove 520, the deformed two groups of arc-shaped elastic pieces 521 rebound to limit the outside of the tray 4, thereby completing the restriction of the infusion bottle 1 and the infusion needle 3, preventing the infusion tube from being pulled and causing the separation of the infusion needle 3 and the infusion bottle 1, which affects the treatment of patients.

[0038] The partition assembly 6 includes two groups of arc-shaped strips 61 fixedly arranged on the lower sides of the two groups of support rods 59. There is a movable frame 62 fixedly arranged at a position close to the rear side between the two groups of arc-shaped strips 61. There is a fixed strip 63 fixedly arranged at a position close to the groove 520 at the lower end of the horizontal support rod 51. There is a U-shaped frame 64 fixedly arranged at the lower end of the fixed strip 63. Two groups of movable rods 65 are movably arranged inside both sides of the U-shaped frame 64. Four groups of limit slide bars 66 are fixedly arranged on the outer sides of the two groups of movable rods 65. Semi-spherical balls 67 are fixedly arranged at the opposite ends of the two groups of movable rods 65. Two groups of second springs 68 are fixedly arranged between the outer sides of the two groups of movable rods 65 close to the semi-spherical balls 67 and the U-shaped frame 64. Clamping blocks 69 are fixedly arranged at the opposite ends of the two groups of movable rods 65.

[0039] The two groups of arc-shaped strips 61, the movable frame 62 and the two groups of support rods 59 are of an integral structure. The structure of the movable frame 62 is trapezoidal. The fixed strip 63 and the horizontal support rod 51 are of an integral structure. The movable rods 65, the limit slide bars 66 and the U-shaped frame 64 are slidably arranged. The two groups of clamping blocks 69 are mirror-symmetric. The two groups of clamping blocks 69 are arranged on the outside of the infusion tube below the infusion needle 3.

[0040] Each time the infusion needle 3 is replaced, the two groups of support rods 59 rotated down respectively drive the two groups of arc-shaped strips 61 and the movable frame 62 to rotate forward. The inclined positions on the sides of the movable frame 62 respectively squeeze the two semi-spherical balls 67 on both sides. The two groups of movable rods 65 drive the two groups of clamping blocks 69 to slide closer, while squeezing the two groups of second springs 68. The two groups of clamping blocks 69 that come closer will squeeze the infusion tube below the infusion needle 3, realizing the partition of the outside air when the infusion needle 3 is pulled out, reducing the air flowing into the infusion tube, and preventing discomfort to the patient.

[0041] A method for using an anti-disconnection fixing device for intravenous therapy is also provided, which is used to operate an anti-disconnection fixing device for intravenous therapy, including the following steps:

[0042] S1: After the infusion needle 3 is inserted into the infusion bottle 1, the fixing ring 514 and the groove 520 are sleeved on the outer sides of the infusion bottle 1 and the infusion needle 3 to restrict the infusion bottle 1 and the infusion needle 3.

[0043] S2: When replacing the infusion bottle, first pinch the two groups of anti-slip strips 55 and rotate the turned-down fixing ring 514. After turning down the fixing ring 514, the infusion needle 3 can be directly pulled out from the infusion bottle 1.

[0044] S3: When replacing the infusion needle 3, the rotating movable frame 62 will squeeze the two semi-spheres 67 on both sides, and pushing the two groups of clamping blocks 69 will squeeze the infusion tube under the infusion needle 3 to cut off the entry of external air.

[0045] Working principle: After the infusion needle 3 is inserted into the infusion bottle 1, the fixing ring 514 and the groove 520 are sleeved on the outside of the infusion bottle 1 and the infusion needle 3. After the two groups of clamping blocks 517 contact the bottleneck of the infusion bottle 1, they shrink and move toward the two groups of movable grooves 516, and at the same time squeeze the two groups of springs 518 until the bottleneck of the infusion bottle 1 moves to the inside of the bottleneck sleeve 515. The two groups of clamping blocks 517 are respectively clamped on the outside of the bottleneck of the infusion bottle 1 and on the upper side of the bottleneck ring 2. Then the groove 520 is sleeved on the outside of the disc holder 4. After the two groups of arc-shaped spring pieces 521 are stretched open by the disc holder 4 and enter the groove 520, the deformed two groups of arc-shaped spring pieces 521 rebound to limit the outside of the disc holder 4, thereby The restriction of the infusion bottle 1 and the infusion needle 3 is completed to prevent the infusion tube from being pulled, resulting in the separation of the infusion needle 3 and the infusion bottle 1, which affects the patient's treatment; when replacing the infusion bottle, the two groups of anti-slip strips 55 can be pinched first to make the two groups of positioning spring pieces 52 close together and deform, and the restriction card strip 1 53 on the positioning spring piece 52 is separated from the restriction card strip 2 512 on the support sleeve 511, so that the fixing ring 514 and the two groups of support sleeves 511 and the support rod 59 can be rotated along the fixing nail 57 respectively, and the two groups of resistance shafts 58 generate rotation damping for the rotating two groups of support rods 59, so as to prevent the turned-down fixing ring 514 from moving randomly, and after the fixing ring 514 is turned down The infusion needle 3 can be directly pulled out from the infusion bottle 1 and then inserted into another infusion bottle 1 by pinching the two groups of pressing blocks 54 and rotating the fixing ring 514 to clamp the bottleneck of the infusion bottle 1 to complete the positioning purpose, and the pressing block 54 is released, and the limiting card strip 1 53 is engaged with the limiting card strip 2 512 again to limit the horizontal support rod 51 and the support sleeve 511, so as to prevent the support sleeve 511 from rotating and being pulled downward, thereby achieving the anti-dropping effect. The depth of each insertion of the infusion needle 3 into the infusion bottle 1 is different, and the horizontal support rod 51 can be directly pushed upward, and the elastic characteristics of the two groups of positioning spring sheets 52 are matched, so that the horizontal support rod 51 and the two groups of positioning spring sheets 52 move upward quickly. The distance between the horizontal support rod 51 and the fixed ring 514 is quickly completed, which is adapted to the different depths of the infusion needle 3 inserted into the infusion bottle 1; in addition, each time the infusion needle 3 is changed, the two groups of support rods 59 that are rotated down respectively drive the two groups of arc-shaped bars 61 and the movable frame 62 to rotate forward, and the inclined position of the side of the movable frame 62 squeezes the semicircular balls 67 on both sides respectively, and the two groups of movable rods 65 drive the two groups of clamping blocks 69 to slide close together, and at the same time squeeze the two groups of springs 68, and the two groups of clamping blocks 69 that are close together will squeeze the infusion tube on the lower side of the infusion needle 3, and when the infusion needle 3 is pulled out, the outside air is isolated, reducing the flow of air into the infusion tube, and preventing discomfort to the patient.
