  • the interior of the blood collecting tube or container is retained in a negative pressure state at a pre-set level corresponding to the blood amount intended to collect.
  • one end or tip of a vacuum blood collecting needle mounted to a holder is penetrated into the vein of the subject, and the other end of the needle is penetrated into the rubber plug body B mounted to one end opening of the vacuum blood collecting tube or container body A so as to communicate the needle with the interior of the tube or container whereby it is capable of collecting the blood of the amount corresponding the predetermined negative pressure within the vacuum blood collecting tube body A.
  • the vacuum blood collecting needle is withdrawn from the vacuum blood collecting tube or container, said tube or container with the collected blood is passed to test or examination.
  • the above object is achieved by the provision of a member which absorbs the blood adhered to the vacuum blood collecting needle when the needle is withdrawn from or inserted into the blood collecting tube or container, and which is intended to prevent any dropping or scattering of the blood to the outside when the vacuum blood collecting needle is separated from the vacuum blood collecting tube or container.
  • the vacuum blood collecting tube or container with contamination prevention means comprises a vacuum blood collecting tube or container body whose one end is opening and whose interior is retained in a determined negative pressure state, a plug body made of an elastomeric member hermetically fitted with the opening of said vacuum blood collecting tube or container body, and an absorbing member which is positioned at the opening region through which at least the blood collecting needle penetrates and which is constituted by an elastomeric material having an absorbing property to liquid.
  • the absorbing member can be constituted by any optional one material of a chemical fiber, a cotton fiber, paper and a synthetic resin which absorb liquid or by-a composite material of the two or more of said materials.
  • the absorbing member is sheet-like and secured to the external surface of the plug body.
  • the absorbing member in the sheet form may also be formed as an external surface layer of the plug body by coating means.
  • the absorbing member is mass-like and secured to the external surface of the plug body.
  • the mass-like absorbing member may be fixed being fitted into the plug body.
  • the vacuum blood collecting tube or container with contamination prevention means is provided, in addition to the above structure, with a cap which is mounted to the outside of the opening of said vacuum blood collecting tube body thereby to prevent said outside portion of the tube body from contamination.
  • the absorbing member may be structured in one body with the plug body and/or the cap.
  • the blood collecting tube or container with contamination prvention means comprises a vacuum blood collecting tube or container body whose one end is opening and whose interior is retained in a predetermined negative pressure state, a sealing member which is hermetically mounted to the flange of the openig of said tube body, a plug member which is secured to the region of said sealing member, through which region at least the blood collecting needle penetrates, and an absorbing member which is fixed onto the plug member and composed of an elastomeric material having absorbability to liquid.
  • the absorbing member assembled with the plug body absorbs the blood staying at the tip of the needle when the vacuum blood collecting tube or container is separated from the vacuum blood collecting needle at blood collection thereby preventing the blood from dropping or scattering to the outside.
  • the blood collector touches the blood in error or part of the blood adheres to the external surface of the vacuum blood collecting tube so as to be left in the dried state, and it is possible always to retain a sanitary environment so that the blood collection or examination can be carried out safely and easily.
  • FIG. 2 illustrates the vacuum blood collecting tube or container according to one embodiment of the present invention.
  • the illustrated vacuum blood collecting tube or container includes a vacuum blood collecting tube or container body 1 whose one end is opening and whose interior is retained in a predetermined negative pressure state.
  • the body 1 is made of a suitable transparent plastic material, and the opening 1a at one end of the tube is hermetically fitted with a plug body 2 which is composed of rubber or an elastomeric polymer such as neoprene, isoprene or chloroprene.
  • the external surface of the plug body 2 is formed in a recessed form, to which is secured a sheet-like abosorbing member 3 made of an elastomeric material having absorbability to liquid.
  • the sheet-like absorbing member 3 can be secured to the recessed external surface of the plug body 2 by means of adhesion, melting or welding, and the thickness of the absorbing member 3 is selected to allow the blood to be sufficiently absorbed from the tip of the needle.
  • the absorbing member 3 may be made of one optional material of a chemical fiber, a cotton fiber, a non-woven cloth, paper, and a synthetic resin in which liquid is absorbable or of a composite material of two or more of said materials.
  • a porous material of ethylene tetrafluoride resin called water-repellent synthetic resin, or a high molecular porous material is usually employed.
  • the vacuum blood collecting tube or container is provided with a cap 4 covering the opening 1a at one end of the tube body 1, the plug body 2 and the absorbing member 3 to prevent contamination of the opening exterior portion of the tube 1.
  • the cap 4 is provided in its center with an opening 4a.
  • a medicament for said purpose can be applied to either the absorbing member 3 or the upper surface of the plug body 2 thereby to construct the blood collecting tube or container body 1 and the absorbing member 3 in one body, and thus the vacuum blood collecting tubes or containers can be manufactured at low cost so as to be economical.
  • the illustrated vacuum blood collecting tube or container thus constructed, since the interior of the tube is in a negative pressure state the blood is sucked owing to the negative pressure by penetrating a blood collecting needle (not shown) into the center of the plug body 2 at blood collection, so that it is possible to collect the blood in the amount corresponding to the negative pressure level. Then, when the needle is withdrawn, a flashback of the blood takes place in the upper surface i.e. external surface of the rubber plug body 2 but the blood is absorbed by the absorbing member 3 to certainly prevent the blood from scattering or leaking.
  • a blood collecting needle not shown
  • FIG. 3 illustrates a modified embodiment of the present invention.
  • the cap 4 has an opening 4a at its center portion, but in the case of this modified embodiment the outside of the central portion 5a of a cap 5 is formed to have a recessed profile, the cap 5 preventing contamination of the opening outside portion of the vacuum blood collecting tube or container body.
  • the other structures are substantially the same as in FIG. 2.
  • FIG. 4 illustrates another embodiment of the present invention, and the portions thereof corresponding to those of the embodiment of FIG. 2 are shown with the identical reference numerals.
  • a sheet-like absorbing member 6 is constituted in two layers which are sticked together by melting or adhering, and the two layers may be constituted by one and identical material or different materials.
  • FIG. 5 illustrates still another embodiment of the invention, in which an absorbing member 7 is formed integrally with a cap 8, being incorporated with the cap, while the cap is secured to the flange portion of the external surface of the plug body 2.
  • FIG. 6 illustrates still further embodiment of the invention.
  • a sealing member 9 of, for instance, a laminate material is hermetically mounted to the flange portion 1b at one end of the vacuum blood collecting tube or container 1, a plug member 10 which can be made of rubber or an elastomeric polymer is secured at least to the region beneath the sealing member 9, through which region the blood collecting needle penetrates, and an absorbing member 11 composed of an elastomeric material where liquid is absorbable is fixed above the plug member 10.
  • FIG. 7 shows a modified example of the embodiment illustrated in FIG. 6.
  • the plug member 10 and the absorbing member 11 are provided while holding the sealing member 9.
  • the absorbing member is formed sheet-like in each of the embodiments as illustrated in the drawings, it can be structured in a massive or block form. Similarly to the embodiments as illustrated in the drawings, even in that case the absorbing member is secured to the external surface of the plug body or formed integrally with the plug body. Otherwise, as shown in FIG. 8, a massive absorbing member 12 is incorporated into the plug body 2. Even in that case, the massive absorbing member 12 can be composed of any one material of a chemical fiber, a cotton fiber, paper and synthetic resin which absorb liquid, or of a composite material of two or more of said materials. Further, in that case and in the case of paper, the paper is applied or impregnated with a starch component such as corn starch, and preferably it is arranged in a suitable form and then dried.
