Definitions

  • ABSTRACT A set for administering a premeasured volume of parenteral solution from a prime fluid supply, utilizing a valve arrangement which prevents the possibility of the prime fluid supply being connected directly to the patient and enables repeat administration without manipulation of an antiairentrainment valve.
  • This invention relates to an apparatus for administering a parenteral solution and is characterized by being especially safe from the standpoint of the person to whom the solution is being administered.
  • the present invention is intended to solve these problems by providing a different way of connecting the measuring chamber with the main fluid supply and the drip barrel with the measuring chamber in a combination such that one cannot at the same time have fluid from the main supply going into the measuring chamber and fluid coming from the measuring chamber to the drip barrel and into the patient.
  • the invention employs a two-way valve which at one time connects a fluid inlet leading from additional stored solution to the volumetric chamber and only at a separate time connects the volumetric chamber to the drip barrel and thence to the patient.
  • the main or prime fluid supply is never connected to the patient.
  • FIG. I is a view of elevation of an apparatus for administering parenteral solution, embodying the principles of the invention.
  • FIG. 2 is an enlarged view in elevation of the measuring chamber and drip barrel, joined by a valve according to this invention, the valve being in the position connecting the measuring chamber to the drip barrel.
  • FIG. 4 is a fragmentary view in section taken along the line 4-4 in FIG. 3, but reduced in scale.
  • FIG. 5 is a view in section taken along the line 5-5 in FIG. 3.
  • FIG. 6 is a fragmentary view similar to FIG. 2, with the valve in the position connecting the prime fluid solution supply to the measuring chamber and simultaneously preventing flow from the measuring chamber to the drip barrel.
  • FIG. 7 is a view in section taken along the line 77 in FIG. 6.
  • FIG. 8 is a fragmentary view in section taken along the line 8-8 in FIG. 7.
  • FIG. 9 is a view in section taken along the line 9-9 in FIG. 7.
  • FIG. 10 is an enlarged view in section of a modified form of valve usable in the present invention.
  • FIG. 11 is a similar view with the valve in a different position.
  • a tubing 10 conducts prepared parenteral solution from a main supply container 11 to a control valve 12.
  • the control valve 112 is a two-position valve; it may have a cylindrical member 13 with a handle 14, that is rotatable in a housing 15 with a cylindrical bore 16.
  • An axial central passage 17 is connected directly from the tubing 10 to a radial portion 18 that in one position (FIG. 6-9 leads into the lower end of a calibrated measuring chamber 20 through a passage 21, and in the other position (FIG. 2-5) the radial passage 18 is cut off from the passage 21.
  • a semicircular peripheral passage 22 connects the passage 21 to a passage 23 that leads directly into the upper end of a drip barrel 24, by a drip outlet 25.
  • the semicircular passage 22 is cut off from the passage 21 when the radial passage 18 is connected to the passage 21.
  • the valve 12 is purposely made so that at no time can the passage 21 be connected simultaneously to both passages 18 and 22.
  • the measuring chamber has an air vent 26 and a medication inlet 27 and is suspended from the tube 10 by a noncommunicating support member 28.
  • a rubber float 30 may be provided to act as a check valve, in connection with a float retainer cage 32. This float valve 30 is elevated from the upper end 33 of the passage 21 when the chamber 20 is being recharged through the tube 10 and valve passages 17 and 18. When closed, it allows a slow drop-by-drop passage of fluid from the chamber 20 to flow by the valve passage 22 and the passage 23 into the drip chamber 24.
  • the lower end of the drip chamber 24 leads by a conduit 34 to a hypodermic needle 35.
  • a conventional flow valve 36 may be used to regulate the rate of flow from the drip chamber 24 to the patient.
  • valve 12 is then returned to the position of FIGS. 6-9, and fluid is caused to flow from the main supply 11 into the measuring chamber 20 until the desired volume is obtained for administration to the patient.
  • the needle 35 may then be injected into the patient and the valve 12 returned to the position shown in FIGS. 2 to 5, and the measured amount is enabled to flow slowly by drops into the drip chamber 24, and from the drip barrel 24 through the conduit 36 to the patient. Since the valve 12 has two operating positions and since in between these positions it is cut off in both ways, it is impossible for the main supply of fluid to be connected directly to the patient.
  • valve 12 When it is desired to administer additional volumes of fluid, the valve 12 is simply returned to the position of FIGS. 6 to 9, cutting off flow to the drip chamber 24 while refilling the measuring chamber 20 to the desired level, and the process is repeated by once again turning the valve 12.
  • prior art sets in order to refill safely, it was necessary to pinch the tubing under the drip chamber 24 with one hand and squeeze the drip chamber 24 with the other hand to make the rubber float 30 rise, or in some other way to manipulate the rubber float 30 until it rises.
  • the float 30 is automatically unseated when the valve 12 is open to fluid supply.
  • valve 12 While the preferred arrangement is the two-position valve 12 at the very bottom of the chamber 20 as shown, this is not always necessary. If desired, in place of a single two-way valve, two valves permanently connected together for operation, so that one must be closed before the other is opened, may be employed, and then one valve may be at a different location from the other, so long as the connection is physically maintained. However, the embodiment shown is usually more convenient.
  • FIGS. and ll show a modified form of two-position valve means 40 for connecting the conduit 10 to the measuring chamber 20 in a first position only, while connecting the measuring chamber 20 to the drip barrel 24 in a second position only.
  • a valve housing 41 has a cylindrical bore 42 in which a cylindrical valve member 43 is rotatable.
  • the passages 21 and 23 are vertical and are part of the housing 41, which also has a horizontal passage 44 connected to the tube 10.
  • the valve member 43 has a through passage 45 and a tee passage 46. When the tee passage 46 is in line with the passage 21 and the passage 45 aligned with the passage 44, the measuring chamber 20 can be refilled, but nothing can pass to the drip barrel 24.
  • the through passage 45 is vertical, the drip barrel 24 is connected to the passage 21 of the measuring chamber, but the tee passage 42 is then cut off.
  • An apparatus for administering a parenteral solution including in combination:
  • conduit connected at an upper end to said fluid supply container and having a lower end connected to a point below said chamber and above said barrel
  • valve means connected to the lower end of said measuring chamber and having a first position in which and only in which it connects said chamber to said conduit and having a second position in which and only in which it connects said measuring chamber to said drip barrel, said valve means having means positively preventing flow of fluid from said conduit to said drip barrel at any time, said apparatus having means connected to the drip barrel for attaching to and supplying parenteral solution to a patient.
  • An apparatus for administering a parenteral solution comprising:
  • valve means connected to the lower end of said measuring chamber and having a first position in which and only in which it connects said chamber to said first conduit and having a second position in which and only in which it connects said measuring chamber to said drip barrel, said valve means having means positively preventing flow of fluid from said first conduit to said drip barrel at any time;
  • passageway means leading to said two-position valve means and closed by said check valve means when said measuring chamber is emlpty, said passage means leading from said measuring c amber via said two-position valve means when it is in its said second position to said drip barrel through an orifice drip;
  • control valve on said second conduit to regulate fluid flow to the patient.
  • check valve means comprises a retainer cage at the lower end of said chamber above the upper end of said passageway means and having an upper wall spaced above said upper end,
  • a fluid supply container having a first conduit leading from a lower end thereof
