Description
2~7~
The present invention relates to a one time use Teflon~M
injection needle set, and is aimed to smooth the transfusion of blood, and injections and to cut off intrusion of bacteria into the cylindrical rods of such a set, in the course of the S transfusion, by sealing the rod and the cylinder with a thin polyethylene shield.
TeflonTM vein needle sets made of metal currently in use are pricked into a blood vessel after which the metal needle of same is removed and the injector connected again. The TeflonTM vein injection needle in use is used in the following manner: 1) The TeflonTM vein injection tube is pricked into the blood vessel by using a metal needle and then the metal needle is removed; 2) The transfusion tube of a blood transfu~ion set, an injection set or an injector is connected to the upper portion of the stopper; and 3) Transfusion of blood or an injection is made by the injector.
Since thi~ injection is made by the use of a metal needle, and the needle is to be removed immediately after the injection and connected to the blood or injection transfusion tube or to the injector, the injection has deficiencies of:
1) Leaking of blood or injection during the connection and injection; 2) Connection not only takes much time and requires that many details be attended to, it require~ an additional replacement Teflon~M tube when the injection tube under 2~ i 71~
injection in one blood vessel is moved to another since the metal needle is removed.
In particular, to inject into another blood vessel, the TeflonTM tube has to be replaced by a new one after the blood or injection transfusion tube is disconnected, and the metal needle must be immediately removed after the replacement needle is pricked into the blood vessel and the tube must be connected to the injector. Therefore, these processes cause a grave deficiency of allowing bacterial infection.
The present invention is designed to provide a one time use TeflonTM vein injection tube set that allows the speedy and smooth transfusion of blood or injection, and is also aimed to keep the needle set free from bacterial infection, by sealing its rod from the atmosphere when injection is taking place with a thin polyethylene shield.
In a broad aspect, the present invention relates to a device for use in effecting intra-venous injection or blood transfusion including: a metal needle having a bore through which blood or fluid to be injected may flow, and a sharp tip capable of penetrating into a vein; a rod co-axial with said needle and having a bore communicating with the bore of said needle which extends from said rod; a cylinder encasing said rod, having a first end from which a Teflon~M tube extends said TeflonTM tube having a bore which snugly fits said needle, and a second end from which the end of said rod remote 2~ 7~
from said needle extends; and a connecting socket extending from and co-axia] with said rod and having a bore communicating with the bore of said rod, said socket being adapted to engage the end of a transfusion or injection tube, wherein said rod is moveable in said cylinder from a first position in which said metal needle protrudes slightly from said teflon tube to a second position in which said metal needle is withdrawn from said TeflonTM tube.

2~
Referring now to the drawings, the transfusion tube (4) is connected from the bottom of the injection container (15) to the top of the TeflonTM needle assembly, and the flow regulator (16) is installed between the two points.
The transfusion tube (4) is inserted into the connecting socket (13) of the connector (2). Protrusions (6) and (7) at the top and bottom of rod (5) co-axial with connector (2) limit the up-and-down movement of the rod (5) within a cylinder (3). Hole (8a) on round plate (8) at the bottom of the rod (5) is aligned to a Teflon~ tube (12) and to a metal needle tightly fitting within the tube (12). The end of the metal needle (9) protrudes approximately 1 mm at the tip of the tube (12) at the time of injection, as can be seen in Fig. 3.
A polyethylene shield is sealed between the upper portion of the cylinder (3) and the lower portion of the connector (2j to keep the rod (5) from the atmosphere and intrusion of bacteria. The shield (20) is made of transparent elastic polyethylene, so the polyethylene shield (20) is transparent and flexible 80 that rod (5) is easily moveable, and constantly visible.
As ~hown on the Figs. 5 and 6, the passage (21) in the round plate (8) and the passage hole (22) in cylinder (3) are furnished and aligned to make the smooth flow of blood or 2 ~ PI ~ ~
injection from the rod bore (17) to the cavity compartment (11~ .
This device is so designed and is used in the following manner, and has the following advantages. Connector (2) is depressed toward cylinder (3), thereby making the metal needle tip protrude about 1 mm at the end of the TeflonTM tube after the transfusion tube (4) is connected to the connecting socket (13) of the connector (2). The metal needle (9) is pricked into the blood vessel and the cylinder (3) held with one hand -and the connector (2) i5 pulled upward with the other hand.
This extends the device to the shape illustrated in Fig. 4.
Then the injection in the container (15) flows into the blood vessel through the transfu~ion tube (4), connecting socket (13), rod bore (17), the metal needle (9), cavity compartment (11), TeflonTM tube (12) and finally into the blood vessel.
The thinner the TeflonTM tube (12) is, the better, as it must have some flexible tension not to hurt the blood vessel of the patient receiving the injection. The metal needle (9) has a vertical bore (14), and moves up and down tightly inside the TeflonTM tube. As shown in Figs. 3 and 4, the flexible polyethylene shield (20) is sealed to the upper part of the cylinder (3) and to the lower part of the connector (2) to protect the rod (5) from being infected by bacteria.
The upper protrusion (6) at the top of the rod (5) maintains proper connections to the connector (2), and the cylinder (3) and the lower protrusion (7) also maintains 2~ 7~ ~
proper connection to the concave groove (10) at the point that the connector (2) is pulled upward to the maximum, and adjusts the moving distance of the connector (2) accordingly. At this point, the tip of the metal needle ~9~ locates at the top of the cavity compartment (11), and makes the transfusion of blood or injection easier, and maintains close contact with the upper part of the cavity compartment (11) whereby reverse flow of blood or injection in the cavity compartment (11~ into the cylinder (3) while the transfusion process is under way is prevented.
Since the transfusion of blood or injection made through the metal needle (9) is small in volume and slow in its flow speed, transfusion is also made through the passage (21) at the bottom of the rod bore (17). A part of the blood or the injection is collected in the cylinder (3), and is again collected in the cavity compartment (11) after passing through the passage hole (22). After the blood or the injection is being collected in the compartment (11), then the transfusion is easily made into the blood vessel through the TeflonTM tube (12).
In the event of relocating the TeflonT~ needle assembly set (1) from one blood vessel to another, the TeflonTM tube ( 12 ) i5 removed from one blood vessel, the connector (2) is returned to the original position (Fig. 3). Injection with the metal needle tip (9) is then carried out, with the tip of the needle (9) protruded about 1 mm out from the tip of the TeflonTM tube (12). At this point, protrusion (6) fits in the concave groove (10).
Hole (8a) on round plate (8) keeps the air pressure inside the cylinder (3) stable to that of the atmosphere.
The tip of the metal needle (9) must be very sharp and the connector should have proper tension.
Since there is a frequent need to move the rod (5) to relocate the TeflonTM tube under the transfusion from one blood vessel to another, polyethylene shield is provided to protect the rod (5) from being infected by bacteria.
This device, therefore, can be used for transfusion, in a simple and speedy manner with the transfusion tube and the injector connected and without any leaking or wasting of the needle by following the simple procedures previously mentioned. And also, this device can make for bacteria free transfusion of blood or injection from one blood vessel to another by sealing the rod that has to be moved during the process, and provides the smooth and stable transfusion effect to the maximum extent by means of the rod bore, passage holes and the cavity compartment.
Furthermore, this device requires no replacing of the transfusion tube or the injector while the transfusion is in 2~17~ ~
process, can make the transfusion by following the simple processes and provides bacterial infection free transfusion.
The present invention relates to a one time use Teflon~M
