Description

A new type of intravenous infusion set

technical field

The utility model relates to an apparatus for injecting a medium into a human body, and specifically designs an intravenous infusion set.

Background technique

Current venous infusion sets include common muffi's dropper and infusion tube, among which muffi's dropper is a transparent tube body, through which the situation of infusion can be observed, such as: whether the infusion is carried out normally, the speed of infusion And whether the liquid medicine has been infused. Its disadvantage is that before the infusion of the liquid medicine is finished, the patient or the nursing staff must observe carefully to avoid the infusion dripping empty, which will lead to air embolism or blood return in the infusion tube, which will cause adverse consequences to the patient and unnecessary troubles to the medical staff. . In order to overcome this problem, a utility model patent specification with the patent No. 200520115348.6 discloses a "multi-functional Mufei's burette". The outlet of the liquid medicine at the bottom of the Phillips dropper is made into a conical shape; when the liquid medicine in the Murphy dropper is almost finished, the floating ball descends with the liquid medicine and is blocked on the liquid medicine outlet, thereby preventing air from entering the human body. It has the advantages of simple structure, convenient use and the like. However, it still requires constant observation by the patient or the caregiver, so that the nurse can be notified in time to pull out the needle or replace the medicinal solution when the infusion stops.

Contents of the invention

The technical problem to be solved by the utility model is to provide an improved infusion device, which can automatically block the outlet of the liquid medicine when the liquid medicine is about to be infused, avoiding air entering the human body, and can automatically alarm.

The technical scheme that the utility model solves above-mentioned technical problem is:

A new type of intravenous infusion device, which includes a conical Mufei's dropper and a floating ball placed in it, characterized in that the intravenous infusion device also includes an alarm device; The lower half of the surface of the floating ball in the Murphy's dropper is covered with a metal layer, and the outlet of the Murphy's dropper is embedded with two electrode sheets, and the surface of the electrode sheet is flush with the surface of the outlet of the Murphy's dropper , and respectively connected to the positive and negative poles of the alarm device power supply.

A new type of intravenous infusion set according to the utility model, wherein, the surface of the upper hemisphere of the floating ball is painted with an easy-to-see color. When there is liquid in the Mufei dropper body, the colored floating ball floats on the liquid and moves continuously under the action of the dripping liquid, which is convenient for observing the speed of rehydration and whether it is unobstructed.

A new type of intravenous infusion device described in the utility model, wherein, the electrode sheet is a magnetic metal sheet. The effect of using the magnetic electrode sheet is that the floating ball will be sucked down in advance before the liquid outlet gradually descends to the liquid outlet naturally, which can not only improve the sealing effect, but also improve the stability of the floating ball fixed on the liquid outlet.

A new type of intravenous infusion device described in the utility model, wherein the alarm device can be an independent voice alarm, also a wireless alarm, the wireless alarm is composed of a transmitting device and a receiving device, Wherein, the positive and negative poles of the power supply of the transmitting device are respectively connected to the two electrode sheets, and the receiving device is arranged at the nurse's station or the treatment room.

In the intravenous infusion device described in the utility model, the lower half of the surface of the floating ball is covered with a metal layer. Since the density of the metal is higher than that of other parts of the floating ball, the floating ball floats in the Mufei dropper. When the liquid medicine is on, the hemisphere with the metal layer is located at the bottom; when the level of the liquid medicine falls after the infusion, the hemisphere with the metal layer is partially blocked on the conical liquid outlet and the alarm is connected. It can be seen that the intravenous infusion set can automatically stop the infusion and send out an alarm signal when the infusion is about to be completed.

Description of drawings

Fig. 1 and Fig. 2 are the structural schematic diagrams of a specific embodiment of the novel intravenous infusion set described in the present invention, wherein Fig. 1 is a front view, and Fig. 2 is an enlarged view of the A-A sectional view of Fig. 1 .

Detailed ways

Referring to Fig. 1 and Fig. 2, the venous infusion set of the present utility model comprises a Murphy's dropper 1, the medicinal liquid input pipe 2 and the medicinal liquid output pipe 3 that are connected to its upper and lower ends and the floating ball 4 that is located in it, wherein , the outlet of Mufei's dropper 1 is conical, and a magnetic electrode piece 5 is embedded on the outlet, and the surface of the electrode piece 5 is flush with the surface of the outlet, so as to ensure the sealing when the float 4 falls to the outlet. Effect: the lower ends of the two electrode sheets 5 extend into the tube body 1-1 below the outlet, and a cut is respectively set on both sides of the tube body 1-1 to expose the two electrode sheets 5, which is convenient for the alarm device 6 for power lead connections. The floating ball 4 is made of plastic with a density lower than that of the liquid medicine, and its size matches the outlet of the liquid medicine. The lower half of the surface of the floating ball 4 is covered with a layer of metal layer 4-1, and the upper half is sprayed with bright-colored paint. color for easy viewing. Described alarm device 6 is a wireless alarm device, is made up of transmitter and receiver, wherein, the positive and negative poles of the power supply of transmitter are respectively connected on above-mentioned two electrode sheets, and receiver is placed in the nurse's station. When the liquid medicine was about to be transfused, the floating ball 4 would drop onto the outlet of the Murphy's burette as the liquid level of the liquid medicine dropped, the outlet would be blocked and the power supply of the launcher would be connected, and the launcher would send a signal that the infusion was complete, and the The receiving device in the nurse's station receives the signal and sends out a voice prompt, informing the nurse of the bed number where the infusion has been completed.
