Description

Flow control blood vessel needle {FLOW CONTROL NEEDLE FOR BLOOD VESSEL}

The present invention relates to a needle for vascular injection into a blood vessel to continuously or regularly inject a certain amount of fluid, drug, blood, etc. into a patient's blood vessel, and more specifically, a user may adjust the flow rate flowing into the needle. The present invention relates to a flow-controlled vascular needle that allows fluid flow from multiple directions into multiple passageways.

Conventional needles do not have a configuration for adjusting the flow rate in the needle itself, it was necessary to adjust the inflow amount externally. For example, when administering Ringer's solution, only the method of controlling the amount of Ringer's solution from Ringer's bottle was used, and there was no configuration to control the flow rate at the needle side.

According to the conventional method, when injecting two or more drugs, it is cumbersome to specify the flow rate individually, and there is a problem that it is difficult to calculate the total amount of the flow rate actually injected into the patient.

The present invention has been made in order to solve the above problems, an object of the present invention is to provide a needle for the blood vessel to adjust the amount of drug to be administered to the patient so that the flow control device is directly connected to the needle.

It is also an object of the present invention to provide a vascular needle that allows a patient to receive two or more drugs with a single needle, by having a chamber that allows two or more drugs to be combined and administered through each route at the same time.

In order to achieve the above object, the present invention includes a tube through which a fluid flows, a chamber into which the tube is fitted into one end of the hole, and an insertion tube fitted into the hole at the other end of the chamber, wherein the insertion tube includes a needle It is characterized by being accommodated. In addition, the chamber is provided with two or more holes, and characterized in that it further comprises a switch for opening and closing any one or more of the holes.

The present invention is characterized in that the pipe is connected to the through hole of the flow control device, the flow control device is provided with a valve for determining the flow rate flowing through the through hole, characterized in that the scale is displayed on the lower side of the valve It is done.

The configuration of the present invention as described above will be described in more detail with reference to the accompanying drawings.

1 is a view showing the chamber and the insertion tube of the present invention. Referring to FIG. 1, the needle bar 30 is fitted into the left side of the tubular chamber 10, and the insertion tube 20 is fitted into the right side.

The chamber 10 has a hole 12 drilled outside thereof, which transmits a fluid flow through an inner tube (not shown). The chamber 10 is made of synthetic resin, and the holes 12 are preferably provided in two or more in various directions.

A hole 12 for delivering a drug to the chamber 10 is formed in the upper and left sides in FIG. 1, and the needle bar 30, which couples the needle 32 to the left side, is fitted to the packing 34. have. The needle 32 penetrates the packing 34 finely, and the packing 34 has excellent restoring force so that the fluid does not leak to the portion even if the needle 32 is removed. This function is called the HEPARIN LOCK function.

The needle 32 of the needle bar 30 penetrates into the chamber 10 and the insertion tube 20, and protrudes slightly longer than the sharp and thin tip 22 of the end of the insertion tube 20. To insert the needle into the human body, first let the needle 32 and the pretreatment 22 penetrate the epidermis together, and leave only the needle 32 inside to the left, leaving the pretreat 22 and leaving the tip of the pretreat 22 Fluid or blood flows toward the side. In order to facilitate the flow, it is desirable to form additional holes 24 in the edges of the ends 22.

After the insert 22 is inserted into the human body, the needle bar 30 is pulled to the left. The needle bar 30 moved to the left and the needle 32 connected to the needle bar 30 are removed from the chamber 10, and even if the needle 32 is removed, the packing 34 through which the needle 32 penetrates has its own restoring force. This seal ensures that fluid will not leak.

The hole 12 of the chamber 10 is coupled to the tube 14 (FIG. 2) through which each drug is delivered and introduced, and each drug is met and mixed in the chamber 10. FIG. The chamber 10 introduces a drug mixed in an internal tube (not shown) into one of the preliminary portions 22 and is administered into the blood vessel of the patient.

2 is a view showing a state in which a switch and one tube are coupled to the chamber of the present invention. 2, the switch 40 is coupled to the chamber 10. The switch 40 may open or close the inlet or outlet of the chamber 10 to allow fluid to flow or stop the chamber 10.

The switch 40 is rotated and opens and closes the path inside the chamber 10. When the end portion 40a having a different shape of the switch 40 is placed in parallel with the tube 14 and the insertion tube 20, the chamber 10 may be blocked, and the chamber 10 may be opened when the switch 40 is vertically moved.

In some cases, when the chamber 10 has three or more holes 12 and is connected to three or more tubes 14 to administer respective drugs, fluids or blood, the switch 40 may close only one tube 14 or , All the tubes 14 can be opened.

3 is a view showing the flow rate control apparatus of the present invention. Referring to FIG. 3, the flow regulator 50 is coupled between the pipes 14, and the valve 52 and the scale 54 are displayed on the flow regulator 50.

The drug introduced from the left tube 14 passes through the flow regulator 50 and passes the amount of drug corresponding to the scale 54 indicated by the valve 52 to the right tube 14. Flow control device 50 has an internal through hole (not shown), the pipe 14 is connected to the through hole.

The valve 52 allows the user to operate by hand, and the tube (not shown) of the through-hole inside the flow regulator 50 according to the rotation of the valve 52 is reduced or stretched in cross section, narrowed or enlarged flow path The flow rate may be adjusted by, for example. As a method for adjusting the flow rate in the flow regulating device 50, a known method can be used.

A scale 54 is marked on the outer surface of the flow regulator 50, and the scale 54 indicates the flow rate per unit time, and the warning to further increase or decrease when the flow rate is close to the allowable value is indicated. Can be displayed.

4 is a view showing a state in which a switch and three tubes are coupled to the chamber of the present invention. Referring to FIG. 4, the chamber 10 is connected to three tubes 14 having three holes 12 in upper, left, and lower directions, in addition to the right direction in which the insertion tube 20 is fitted. Forming three holes 12 at intervals of 90 degrees allows the drug to be introduced from three places is also called a 3-way method.

Each pipe 14 may be connected to the flow rate control device 50, it is possible to adjust the path by turning the switch 40. For example, the direction of the switch 40 in the shape of the portion indicated by 40a is closed, and the path in the direction of the switch 40 in the shape of the portion labeled 40b is opened so that only two of the three types of drugs are introduced, or both You can stop it.

Flow control device 50 is preferably connected to each of the plurality of pipes (14) connected to the chamber (10). The flow rate of each tube 14 is appropriately adjusted so that the drug introduced into the chamber 10 is mixed in the intended mixing ratio in the chamber 10 is introduced into the blood vessel through the insertion tube 20.

The present invention is provided with a chamber for mixing the drug flowing from a plurality of pipes, it is possible to simultaneously administer several types of drugs with a single needle has the effect of promoting the convenience.

In addition, the present invention can control the inflow of the drug, it is possible to precisely administer a plurality of drugs by the appropriate amount required by the patient, and has the effect of easily adjusting the amount.
