Abstract

The utility model relates to a transfusion alarm device, which is mainly composed of a needle head (7), a hard plastic guide tube (6), a stainless steel conducting wire (2), a stainless steel probe which is a cathode (4) of an alarm circuit, and an interface (5) of the alarm circuit. The metal stainless steel conducting wire (2) is led out at the tail end of a needle head of a transfusion guide tube which is inserted in one end of a transfusion bottle by means of the characteristic of weak conductivity of liquid, and is connected with a metal part of the needle head (7) at a connection point (1). The other end of the needle head of a transfusion guide tube is connected with an anode (3) of the alarm circuit. The interface (5) of the alarm circuit is connected with the outer wall of the hard plastic guide tube (6) into integration. Then, the interface (5) of the alarm circuit is connected with a luminous and acoustic alarm device. Thus, a set of complete transfusion alarm system is formed.

Description

Infusion alarm
This utility model belongs to medical apparatus and instruments.
Present medical venous transfusion needs medical personnel or family numbers of patients that the transfusion situation is carried out manual monitoring.When injection will be use up, medical personnel must in time close transfusion catheter.Can not in time close tube for transfusion when artificial carelessness occurring, human vein blood can flow into transfusion catheter when liquid to be injected was failed to the greatest extent, " blood back " phenomenon occurred, brought misery to the patient.
The purpose of this utility model be for fear of artificial carelessness to bring painful of patient and alleviate medical personnel's labor intensity and family members' burden, provide a kind of and can monitor transfusion situation and the infusion alarm of initiatively reporting to the police automatically to medical personnel.
This utility model is applicable to all kinds of medical institutions, and its outstanding advantage is: simple in structure, cheap, safe and reliable, and networking according to actual needs, systematization is used.
The purpose of this utility model is achieved in that described infusion alarm is that negative electrode (4), the warning circuit interface (5) of warning circuit is formed by syringe needle (7), duroplasts conduit (6), contact (1), rustless steel lead (2), the anode (3) of warning circuit, stainless guiding principle probe mainly.Utilize the characteristic of liquid weak inductive, draw a metal rustless steel lead (2) at the transfusion catheter syringe needle end that inserts infusion bottle one end and partly be connected in contact (1) with syringe needle (7) metal, and the other end is connected with warning circuit anode (3), metal rustless steel lead (2) should be sealed in the duroplasts conduit (6), metal rustless steel probe is that warning circuit negative electrode (4) is bumped in duroplasts conduit (6) wall, the one end penetrates in duroplasts conduit (6) wall, the other end exposes outside duroplasts conduit (6) wall, warning circuit interface (5) is connected as a single entity with the outer wall of duroplasts conduit (6), with warning circuit interface (5) and luminous, sounding alarm is connected and promptly constitutes the complete transfusion warning system of a cover again.Its work process is as follows: when between the negative electrode (4) of syringe needle (7) and warning circuit liquid being arranged, because the weak inductive of liquid, electric current can pass through lead (2) from the anode (3) of warning circuit, syringe needle (7), the negative electrode of warning circuit (4) flows out and constitutes the loop, at this moment warning circuit interface (5) has electric current to pass through, the alarm normal-closed end is closed circuit, and when the liquid in the transfusion device is used up, the negative electrode (4) of syringe needle (7) and warning circuit, no liquid between the anode of warning circuit (3), thereby warning circuit interface (5) no current passes through, therefore the alarm normal-closed end is opened a way, and alarm will send alarm signal.
Below in conjunction with accompanying drawing this utility model is described further.
Accompanying drawing 1 is a structural representation of the present utility model.
The described as can be known infusion alarm of accompanying drawing 1 is that negative electrode (4), the warning circuit interface (5) of warning circuit is formed by syringe needle (7), duroplasts conduit (6), rustless steel lead (2), stainless guiding principle probe mainly.The characteristic of utilizing the liquid weak inductive is drawn a metal rustless steel lead (2) at the transfusion catheter syringe needle end that inserts infusion bottle one end and partly is connected in contact (1) with syringe needle (7) metal, and the other end is connected with warning circuit anode (3), rustless steel lead (2) should be sealed in the duroplasts conduit (6), the rustless steel probe is that negative electrode (4) is bumped in duroplasts conduit (6) wall, the one end penetrates in the tube wall (6), the other end exposes outside the tube wall (6), warning circuit interface (5) is connected as a single entity with duroplasts conduit (6) outer wall, again with warning circuit interface (5) and luminous, sounding alarm is connected and promptly constitutes the complete transfusion warning system of a cover.Wherein warning circuit anode (3) and rustless steel probe be negative electrode (4) can to adopt diameter be that 0.08--0.25 centimetre stainless steel silk is made, and the terminal spacing of warning circuit anode (3) and syringe needle (7) is 2.0-10.0 centimetre.

Claims (4)

1, a kind of infusion alarm, it is characterized in that: described infusion alarm is mainly by syringe needle (7), duroplasts conduit (6), contact (1), rustless steel lead (2), the rustless steel probe is alarm circuit negative electrode (4), alarm circuit anode (3), alarm circuit interface (5) is formed, rustless steel lead (2) partly is connected in contact (1) with the metal of syringe needle (7), and the other end is connected with alarm circuit alarm circuit anode (3), metal rustless steel probe is that warning circuit negative electrode (4) is bumped in the wall of duroplasts conduit (6), the one end penetrates in hard plastic tube (6) wall, the other end exposes outside the wall of hard plastic tube (6), and circuit interface (5) is connected as a single entity with duroplasts conduit (6) outer wall.
2, infusion alarm according to claim 1 is characterized in that: rustless steel lead (2) should be sealed in the duroplasts conduit (6).
