Description

Anti-drop transfusion fixing device

Technical Field

The utility model relates to the field of medical equipment, in particular to anti-drop infusion fixer.

Background

When the elderly select the infusion therapy, the following two problems should be noted:

(1) the puncture hole is protected against. The old people have poor elasticity of blood vessels and are hard, brittle and slippery, so that the difficulty of venipuncture is increased. The skin of the old with weak constitution is loose, and the needle head is not easy to fix; the blood vessel of the old with chronic disease and poor constitution has strong fragility and permeability, and is easy to leak, so that the medicine can permeate into the subcutaneous tissue. The elderly are not sensitive to pain and swelling, and if the symptoms are not found timely, the serious people can cause local skin and tissue necrosis. In addition, the elderly and the infirm preferably select the bed-ridden infusion to reduce the physical consumption caused by overlong infusion time.

(2) The infusion rate should not be too fast. The senile myocardial cell atrophy can lead to myocardial ischemia and even heart failure due to the physiological hypofunction of heart, such as excessive transfusion. Therefore, 20-40 drops per minute is suitable for the elderly to transfuse. If the dropping is too slow, the effect of the medicine will be affected if the dropping is too long. The dripping speed of the heart failure patient should be controlled to be 15-30 drops per minute so as to avoid accidents caused by increase of heart burden.

Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is a schematic structural diagram of the present invention, and fig. 2 is an enlarged schematic diagram of a in fig. 1. Referring to fig. 1 and 2, an anti-drop infusion fixer comprises a multi-claw infusion support 1. The multi-claw infusion support 1 comprises a longitudinal stainless steel rod and a plurality of lifting hooks. One end of each of the lifting hooks is arranged on the stainless steel rod. In this embodiment, the number of the claw heads of the lifting hook of the multi-claw infusion support 1 is four. The claw head of the multi-claw transfusion stand 1 is tied with a rope 2. The rope 2 is provided with a control buckle 3 for adjusting the tightness. The puncture needle holder 4 is mounted on the rope 2.

Fig. 3 is a sectional view of the lancet holder of fig. 1. Referring to fig. 1 and 2, the puncture needle holder 4 includes a housing cover 41 and a housing base 42 that are engaged with each other. Specifically, a convex male buckle is arranged in the circumferential direction of the housing cover 41, a concave female buckle is arranged in the circumferential direction of the housing base 42, and the number of the male buckles is consistent with that of the female buckles. A ratchet wheel 43 is mounted between the housing cover 41 and the housing base 42. The inner edge of the ratchet wheel 43 is provided with a gear with a rigid toothed surface or a friction surface. The cord 2 is wound around the ratchet 43 a plurality of times in the circumferential direction and is passed out from one end of the housing cover 41. The ratchet 43 has a locking block 44, a locking seat 45, a pawl 46 and a pawl sleeve 47 fixed therein in this order in a radial direction. Two ends of the locking block 44 are sleeved with springs 48, and two ends of the locking block 44 extend into the through holes of the locking seat 45. The top of the locking block 44 has a gear that engages the gear of the ratchet 43. The back of the locking block 44 protrudes outward, and the locking block 44 can be moved by the housing cover 41, so that the locking block 44 moves longitudinally. The locking socket 45 is fixed to the housing cover 41 by bolts. The pawl 46 extends into a pawl sleeve 47. The pawl sleeve 47 is fixed to the housing cover 41 by bolts. One end of the cord 2 that exits the housing cover 41 is tied to the loop of the jaw 5. The clamping jaw 5 clamps the transfusion needle 6. The transfusion needle 6 is inserted into the mouth of the transfusion bottle 7. The bottom of the transfusion bottle 7 is hung on the claw head of the multi-claw transfusion stand 1.

The multi-claw infusion support 1 is arranged on the vertical fixed seat or clamped in the annular infusion track.

The utility model discloses a use method as follows:

firstly, the bottle bottom of the infusion bottle 7 is hung on the claw head of the multi-claw infusion support 1, and the height of the multi-claw infusion support 1 is enough to ensure that the delivered liquid can stably enter the body of a patient. The transfusion needle 6 is inserted into the mouth of the transfusion bottle 7. The control button 3 is tightened or loosened, and the adjusting rope 2 is tightly sleeved on the claw head of the multi-claw infusion support 1. By adjusting the length between the rope 2 and the loop of the jaw 5, the locking block 44 can be pulled downwards, and the spring 48 drives the locking block 44 to move downwards, so that the gear at the top of the locking block 44 is separated from the gear at the inner edge of the ratchet 43. Simultaneously, the length between the rope 2 and the ring buckle of the clamping jaw 5 is stretched, so that the ratchet wheel 43 can rotate along with the needle, the pawl 46 can slide on the gear of the ratchet wheel 43, the ratchet wheel 43 can do unidirectional intermittent motion, and the falling of the infusion needle head 6 is effectively prevented while the stretched rope 2 is prevented from being rapidly withdrawn.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
