Abstract

PROBLEM TO BE SOLVED: To provide a safely used and inexpensive vacuum blood-collecting holder having good operability, wherein a pair of needle loading supporting members having a female twister engaged with a male twister fixed to the hub of a blood-collecting needle are combined so as to be slid in each inner peripheral surface roughly semicircular in section. SOLUTION: The other needle loading supporting member is slid toward one needle loading supporting member and these are coincided with each other. In this state, a blood-collecting needle is loaded. After blood-collecting work is over, the other needle loading supporting member is pushed down in an arrow direction 6, the other needle loading supporting member is unhooked from the outer edge part of one needle loading supporting member and, by pushing these sequentially in a horizontal direction, the other needle loading supporting member is moved in a direction away from one needle loading supporting member, and the twister engagement of a blood-collecting needle is released and dropped down. In this case, when the blood-collecting needle is removed from a holder, a male twister fixed to the hub of the blood-collecting needle to be released is easily and surely dropped while engagement thereof with the female twister of one needle loading supporting member is released.

が、ホルダーは何回も繰り返して使用されている。2. Description of the Related Art Various types of vacuum blood collection holders of this type have been conventionally proposed. Generally, one end of the holder is inserted through a blood vessel of a blood-collecting subject, and the other end is inserted through a vacuum blood collection tube. A needle mounting support portion formed to engage with a male screw provided on the outer periphery of a hub attached to an intermediate portion of the blood collection needle is formed integrally with the holder at the tip of the holder. (See the back of Japanese Patent Publication No. 7-32766). In such a vacuum blood collection holder, at the time of use, the blood collection needle used for the needle mounting support provided at the tip of the vacuum blood collection holder is screw-engaged, and after the blood collection operation, the blood collection needle is rotated and removed from the holder, Discard, while the vacuum blood collection holder is ready for the next blood collection. As described above, the blood collection needle is disposable each time from the viewpoint of preventing infection and ensuring safety, but the holder is repeatedly used many times.

着脱操作に手間がかかるという問題があつた。In such a screw engagement type vacuum blood collection holder, the blood collection needle is not used when the blood collection needle is mounted, so that there is no particular problem even if an operator directly touches the blood collection needle, but after the blood collection, the blood collection needle is removed from the holder. When removing the blood collection needle, not only may the blood collection needle touch the blood collection needle, but it is necessary to rotate the blood collection needle to disengage the screw engagement with the holder, which requires time and effort. In addition, since the blood collection needle used for vacuum blood collection is usually equipped with a cap, the blood collection needle must be attached to and detached from the holder with the cap attached, which is extremely difficult in terms of stability when attached. Excellent, but
If you do not ripcap after blood collection, it will not separate or difficult to separate,
There is a problem that it takes time to attach and detach.

A pair of needle mounting support members each having a female screw engaging with a male screw provided on the hub of the blood collection needle on the inner peripheral surface having a substantially semicircular cross section. The blood collection needle is configured to be slidable laterally between a mating position where the two mated with each other and a separated position where the blood collection needle is fitted with the pair of needle mounting support members being mutually matched. In the vacuum blood collection holder, one of a pair of needle mounting support members is fixed to an end surface of one end of the holder body, and further includes a support recess that slidably supports the other needle mounting support member in a lateral direction. The other slidable needle mounting support member has a plate shape, The end is elastically bendable, and the elastically bendable one end is provided with a hook for engaging one needle mounting support member, and the other needle mounting support member is provided with the other needle mounting The present invention is characterized in that the supporting member is provided with a step which comes into contact with a stopper for preventing the supporting member from coming off one of the needle mounting supporting members. In a preferred embodiment of the present invention, one of the needle mounting support members fixed to the end face of one end of the holder main body can be integrally formed with the holder main body. Further, according to a preferred embodiment of the present invention, the stopper portion for preventing the other needle mounting support member from coming off the one needle mounting support member can be formed integrally with the holder body. Furthermore, an edge of the opening of the other needle mounting support member through which the blood collection needle passes is elastically bendable at one end, and the male screw provided on the hub of the blood collection needle to be released when the pair of needle mounting support members is separated. It may be configured to release the engagement between the child and the female screw of one of the needle mounting support members. This prevents the male screw provided on the hub of the blood collection needle to be released from remaining engaged with the female screw of one of the needle mounting support members when the blood collection needle is removed from the holder, and can be easily removed. In addition, the blood collection needle can be reliably removed from the holder.

る。As described above, in the vacuum blood collection holder according to the present invention, the female screw engaging with the male screw provided on the hub of the blood collection needle is provided on the inner peripheral surface having a substantially semicircular cross section. Since a pair of provided needle mounting support members are slidably combined with each other, the number of components can be reduced, and only one needle mounting support member can be slid laterally with one hand to be screwed in. The blood collection needle can be easily detached from the device, so operability is good and the needle mounting support members can be securely hooked together, so the blood collection needle is securely held even when a large external force is applied. become able to. Therefore, the present invention can provide an inexpensive vacuum blood collection holder that has good operability and can be used safely.
