Description
Technical Field
The invention belongs to the technical field of infusion sets, and particularly discloses an infusion set plug.
Background
The infusion apparatus is a common medical consumable material and is mainly used for intravenous infusion, the intravenous infusion directly drips a large amount of sterile liquid medicine into veins by utilizing the action of hydrostatic pressure and atmospheric pressure, and the quality and the efficiency of the intravenous infusion are directly influenced by the quality of the infusion apparatus. At present, an infusion apparatus used clinically mainly comprises an infusion apparatus plug, an infusion tube, a Murphy's dropper, a flow control switch, a puncture needle head and the like, when the infusion is performed on a patient, the infusion apparatus plug needs to be inserted into an infusion bottle/bag, and then the vein puncture is performed on the patient.
However, the infusion set plug has the following problems in the using process: 1. during transfusion, because the plug of the transfusion device is of a pure pointed structure and is simply inserted into a transfusion bottle/bag without being fixed on the transfusion bottle/bag, the plug is easy to fall off under the action of gravity or external force, thereby causing pollution; when the infusion bottle/bag is replaced, the plug of the infusion apparatus is exposed in the air and is easy to be polluted, and when the polluted plug is inserted into a new infusion bottle again, bacteria can be brought into the liquid medicine, so that iatrogenic infection is caused; in order to ensure the safety, the infusion apparatus must be replaced again, but this not only wastes medical consumables, but also brings psychological pressure to patients and their families, increases treatment cost, and may even cause disputes between doctors and patients or between nursing and nursing patients.
2. In the use process of the infusion apparatus and the recycling treatment process after the infusion apparatus is used, medical workers or related working personnel need to carry out related operations on the infusion apparatus, and the plug of the infusion apparatus is relatively sharp, so that the personnel are easily injured by mistake.
3. During infusion, when the plug is inserted into an infusion bottle/bag, a small amount of liquid medicine may flow out from a gap between the bottle plug of the infusion bottle and the plug, or liquid leakage may occur when the infusion bottle/bag is replaced, and the liquid medicine leaks on the hands of medical staff or patients to cause pollution or injury, or other articles such as clothes, bed sheets and the like.
Disclosure of Invention
The invention aims to provide an infusion apparatus plug, which solves the problems that the infusion apparatus plug is easy to fall off and the infusion bottle is polluted when being replaced.
In order to achieve the purpose, the basic scheme of the invention is as follows: a plug of an infusion apparatus comprises a plug, and further comprises a fixing part, an accommodating part and a sliding part which are sequentially arranged from top to bottom, wherein the fixing part is fixedly connected to the top of the accommodating part, and the fixing part is used for fixing the accommodating part on an infusion bottle; the accommodating part is provided with a cylindrical cavity, and the plug is positioned in the cylindrical cavity; the sliding part is connected with the accommodating part in a sliding manner, the upper end of the sliding part is provided with a plug seat for installing a plug, the sliding part is also provided with a channel, one end of the channel is communicated with the plug, and the other end of the channel is connected with a transfusion tube; the top wall of the accommodating part is provided with a through hole, and a penetrable baffle used for sealing is arranged in the through hole.
The working principle of the basic scheme is as follows: when the plug is used, the accommodating part is fixed on an infusion bottle by the fixing part, then the sliding part is pushed, so that the plug is close to the bottle stopper of the infusion bottle, and the plug punctures the separation blocking piece and then punctures the bottle stopper to enter the infusion bottle; when the infusion bottle needs to be replaced, the sliding part is pushed firstly to enable the plug to return to the cylindrical cavity, and then the fixing part is taken down, so that the infusion bottle can be replaced.
The beneficial effect of this basic scheme lies in:
1. the plug of the infusion apparatus in the scheme has a simple principle structure and is safe and convenient to use, and the accommodating part is fixed on the infusion bottle by arranging the fixing part, so that the plug can be prevented from falling off under the action of external force in the infusion process; through set up the cylindricality cavity that is used for holding the plug and be used for removing the sliding part of plug in holding the portion, when changing infusion bottle/bag, retrieve the plug in the cylindricality cavity, effectively avoided the plug to expose in the air, can not cause the pollution.
2. In the infusion apparatus plug in the scheme of use, if the condition of weeping takes place, the liquid medicine that flows out can enter into the cylindricality vestibule of holding portion along the through-hole at holding portion top, can effectively avoid the liquid medicine to spill and leak and cause pollution or injury on medical staff or patient's hand, perhaps pollutes other article such as clothing sheet.
3. The plug of the infusion apparatus in the scheme can be rapidly and conveniently controlled to extend out and retract in the using process, and medical care personnel can be completely protected from being accidentally injured by the plug when the infusion apparatus is used or an infusion bottle/bag is replaced; and related workers are protected from being accidentally injured by the sharp plug in the cleaning or recycling process of the infusion set after use.
