Description

Rotary connection type anti-drop infusion apparatus

Technical Field

The invention relates to an infusion apparatus, in particular to a screwed anti-drop infusion apparatus.

Background

An infusion apparatus is a medical appliance for infusion. The application method is that the liquid in the bottle or the transfusion bag is hung at a high position, the liquid flows into the vein through the hose of the transfusion device by the action of gravity, the flow rate is manually adjusted by a flow rate regulator arranged on the hose, and the adjustment index is the dropping speed (dropping/minute) in the dropper. The applicant is used as an integrated medical staff, and in daily work, children and old people often shake or pull the infusion apparatus in the infusion process, so that the plug needle at the upper end of the infusion apparatus is separated from the sealing cover or the sealing plug of the infusion bottle or the infusion bag, the infusion is interrupted, the plug needle of the infusion apparatus is polluted after falling off, the plug needle cannot be inserted into the infusion bottle or the infusion bag again, and the complete and effective infusion treatment is influenced; in addition, the prior brown infusion bottle or infusion bag package adopted for the liquid medicine needing light shielding, but in the process of slow infusion, part of the liquid medicine in the transparent infusion apparatus is easy to be oxidized, decomposed, discolored and the like due to the illumination effect, so that the titer of the medicine is reduced, color and precipitation are generated, the quality of the medicine is seriously influenced, even toxic medicines of the medicine are increased, and the hidden danger of medical accidents exists.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the rotary-connection type anti-falling infusion apparatus which is simple in structure and convenient to use, can effectively fix the infusion apparatus, prevents the plug needle of the infusion apparatus from falling off the infusion bottle or the infusion bag, meets the requirements of shading or shading liquid medicine infusion and ensures safe and effective infusion treatment.

The technical scheme adopted by the invention is as follows: the utility model provides a connect formula anti-drop transfusion system soon, includes plug needle, hose, dropping funnel, flow regulator and the transfusion needle that connects gradually, the plug needle includes taper contact pin and contact pin seat, its characterized in that: the outer conical surface of the conical contact pin is provided with more than one circle of spiral grooves, the spiral grooves extend towards the inside of the conical contact pin and communicate the contact pin base to the hose, the conical contact pin is connected with the contact pin base, the outer circumference of the contact pin base is screwed with a connecting sleeve, and the internal thread of the connecting sleeve is screwed with the circumference of a sealing plug/cover of an infusion bottle/bag; the sleeve wall of the connecting sleeve is a hollow cavity with a ring-shaped sleeve plug for plugging, and a circle of tubular light shielding film or tubular light shielding film connected to the ring-shaped sleeve plug is compressed and reserved in the hollow cavity.

And a filter is arranged on a connecting hose between the flow regulator and the infusion needle.

The connecting hose between the plug needle and the dropping funnel is provided with a clip, or the connecting hose between the dropping funnel and the flow regulator is provided with a clip.

And an exhaust port with an exhaust plug is arranged on the plug needle seat of the plug needle.

The dropping funnel is a self-exhaust dropping funnel.

A hydrophilic membrane or a filter is arranged in the dropping funnel.

After the technical scheme is adopted, the invention has the beneficial effects that:

1. after the conical contact pin of the plug pin penetrates through the sealing plug/cover of the infusion bottle/bag to enter the infusion bottle/bag, a circle of spiral groove is arranged on the outer conical surface of the conical contact pin and is screwed into the plastic or rubber sealing plug/cover, the thread is tightly bitten, in the infusion process, even if a subsequent hose of the infusion apparatus shakes or is pulled or a non-medical worker directly pulls, the plug pin and the infusion bottle/bag which are tightly bitten by the thread can effectively prevent the plug pin at the upper end of the infusion apparatus from dropping out of the sealing cap or the sealing plug of the infusion bottle or the infusion bag, and safe and effective infusion treatment is; when the medical staff operates correctly, the plug needle is rotated in the opposite direction, and the plug needle is disengaged from the infusion bottle/bag due to the fact that the plug needle is snapped by the threads, so that the infusion safety is improved; meanwhile, the spiral groove extends towards the inner part of the conical contact pin and is communicated with the contact pin base to the hose, and the liquid medicine can be output from the outer conical surface of the conical contact pin to the hose, so that the problem that the liquid medicine at the bottom of the infusion bottle/bag can not be output due to liquid discharge of the head part of the conical contact pin is solved, and the utilization rate of the liquid medicine in the infusion bottle/bag is improved.

2. After the conical contact pin of the plug pin penetrates through the sealing plug/cap of the infusion bottle/bag to enter the infusion bottle/bag, the connecting sleeve connected on the contact pin base of the plug pin is screwed to the peripheral side of the sealing plug/cap of the infusion bottle/bag to realize the screw thread screwing connection, in the infusion process, even if the subsequent hose of the infusion apparatus shakes or pulls, the infusion apparatus and the infusion bottle/bag are firmly connected, the plug pin at the upper end of the infusion apparatus can be effectively prevented from being separated from the sealing cap or the sealing plug of the infusion bottle or the infusion bag, the safe and effective infusion treatment can be completed at one time, and the infusion efficiency and the safety are improved;

3. set up the tubulose membrane or the tubulose photomask of keeping away light that the round is connected on annular cover stopper in the cavity of the cover wall cavity of adapter sleeve, when infusion needs shading or light-resistant liquid medicine, extract annular cover stopper and pull the tubulose membrane or the tubulose photomask of keeping away light of compression in the cavity intracavity, along transfusion system hose direction suit, can realize the holistic shading of transfusion system and light-resistant, avoid the illumination to the effect of liquid medicine, satisfy light-resistant or shading liquid medicine infusion requirement, ensure safe effective infusion treatment.

4. The filter is arranged on the connecting hose between the flow regulator and the infusion needle, and the filter is arranged in the dropping funnel, so that particles in the liquid medicine can be effectively filtered, the harm of the particles to a patient is avoided or reduced, and the reduction of infusion reaction and side effect is facilitated; a clip is arranged on a connecting hose between the plug needle and the dropping funnel, or a clip is arranged on a connecting hose between the dropping funnel and the flow regulator, the clip can block the liquid medicine delivery in the hose at any time, and the adjustment operation of the transfusion quantity or the interruption of the transfusion operation are convenient; the plug needle is provided with an exhaust port with an exhaust plug on the needle inserting seat, the dropping funnel is a self-exhaust dropping funnel, and the hydrophilic film is arranged in the dropping funnel, so that air in infusion can be effectively exhausted or absorbed, and the infusion safety is improved.
