Description

Anti-drop infusion couple

The technical field is as follows:

the utility model relates to a medical appliance, in particular to an anti-drop infusion hook.

Background art:

at present, most patients in hospitals need infusion treatment, and the infusion hook is convenient to install and use, effectively reduces the workload of medical staff, becomes a necessary medical use apparatus for medical care units such as various hospitals and the like, and is convenient for hanging an infusion bottle or an infusion bag when the patients need infusion. As shown in figures 1-3, the existing infusion hook comprises a main rod body 1, a top disc 2 and a hook 3, wherein the top disc 2 comprises a base 21 and a cover plate 22, the lower end of the base 21 is fixedly installed at the top end of the main rod body 1, the cover plate 22 is fixedly covered on the base 21, the hook 3 is arranged between the base 21 and the cover plate 22, and the hook 3 can be upwards turned by 90 degrees. The infusion hook has simple structure, convenient manufacture and low cost. But the hooks 3 of the infusion hook are separately and fixedly arranged in the top disc 2, the top ends of the hooks 3 are stressed to tilt upwards to jack the gland plate 22, and the heavier infusion bottles cause overweight pressure to the hooks 3 for a long time, so that the hooks 3 deform and are damaged, even fall off from the top disc 2, and medical accidents are caused.

The infusion hook is small in bearing capacity, easy to deform and even fall off after being hung with heavy objects for a long time, short in service life and high in use cost. In order to overcome the defects of the existing infusion hook, the applicant invents an anti-falling infusion hook through design and tests, wherein an anti-falling part for fixing the hook is a key technology.

The utility model has the following contents:

the utility model aims at providing an anti-drop infusion couple, stable in structure is firm, and the couple bearing capacity is strong, can not the atress drop in the use, stops because of the couple medical accident that drops and lead to, long service life.

The utility model adopts the following technical scheme:

the utility model provides an anti-drop infusion couple, includes the main rod body, pushes up dish and couple, and the couple setting is on pushing up the dish, and the couple can upwards overturn 90, characterized by: the top disc comprises a base, a cover plate and an open annular pin, the lower end of the base is fixedly mounted on the top end of the main rod body, n hook containing grooves are formed in the base in the circumferential direction, n is larger than or equal to 1, pin grooves are formed in the plate bodies on two sides of the hook containing grooves, a sleeving hole is formed in the non-hook end of the hook, the hook is sleeved on the open annular pin through the sleeving hole, the open annular pin is placed in the pin grooves, the hook is placed in the hook containing grooves, and the cover plate is fixedly covered on the base.

Furthermore, be provided with two at least step holes along circumference on the base, form spacing step between the upper bore in step hole and the lower hole, the position department that corresponds the step hole on the apron is provided with the location convex body, the external diameter of location convex body is between the upper bore in step hole and the aperture of lower hole, the location convex body suit is in the upper bore in step hole, the bottom of location convex body is spacing by spacing step, be provided with the screw hole on the protruding body of location, connecting screw passes the fixed spiro union of step hole in the screw hole, with apron fixed connection on the base.

Furthermore, four step holes are symmetrically arranged on the base along the circumferential direction.

Furthermore, four hook accommodating grooves are symmetrically arranged on the base along the circumferential direction.

Furthermore, a turnover groove is arranged on the cover plate corresponding to the installation position of the hook, the groove width of the turnover groove is larger than the width of the hook, and the hook can be turned over in the turnover groove.

Further, the open ring pin is a metal ring pin.

Further, the hook body of the hook can be arranged upwards or downwards.

Furthermore, the sleeving hole is a round hole, and the aperture of the sleeving hole is larger than the diameter of the ring body of the opening ring-shaped pin.

Because be provided with the cyclic annular round pin of opening between base and apron, the couple suit is on the cyclic annular round pin of opening, and all couples pass through the cyclic annular round pin of opening and form a whole, and during the use, couple atress non-hook end perks upwards, bears the transmission power by the cyclic annular round pin of opening, and the couple can not cause the extrusion with the apron, and couple non-deformable damages, and just alone the couple can not drop from the top dish, stops because of the medical incident that the couple drops and leads to. A limiting structure is arranged between the base of the top plate and the cover plate, so that the base and the cover plate are more stable and convenient to install. The hook can be upwards turned by 90 degrees, and when the medical hook is not used, the hook can be upwards turned and folded, so that the hook is prevented from being exposed and damaged by collision, or the hook collides with a patient and medical care personnel to cause injury to the human body. The utility model discloses stable in structure is firm, and the couple bearing capacity is strong, can not the atress drop in the use, stops because of the couple medical accident that drops and lead to, long service life.
