DRAINAGE TUBE Filed Oct. 4, 1934 Patented Mar. 2, 1937 UNITED STATS PATT rice DRAINAGE TUBE 7 Ward R. Smith, Dayton, Ohio Application October 4, 1934, Serial No. 746,801

Claims.

This invention relates to embalmers instru ments and more particularly to a drainage tube for removal of blood having provision for clearing the tube of blood clots or other obstructions.

After death the arteries are found empty and the blood supply collected in the veins. Toprevent discoloration and distention or pufiing while a preservative embalming fluid is being injected into the arteries, it is customary to withdraw the contents of the veins.

For this purpose an elongated tube is introduced into one of the larger and easily accessible veins. Usually the axillary vein or its continuation, the basilic vein, is selected, which when the arm is extended, is substantially aligned with the subclavian vein permitting the drainage tube to be introduced to approximately the juncture with'the internal jugular vein where the vessels are materially larger than the'diameter of the tube and afford ample clearance for free blood flow.

While for the most part the blood continues fluid and flows freely, occasionally through separation or disintegration jelly-like clots and stringy masses of fibrin are formed which tend to clog the entrance to the drain-age tube and arrest the blood fio-w. Various devices have heretofore been proposed for dislodging such obstructions and for cutting the clot or mass. However, such appliances afford but temporary relief and the dislodged material again collects at the I tube inlet.

The purpose of the present invention is to enable the removal of such obstructing masses by initially distending the blood vessel about the intake to the tube and so release any compacted mass of material, and thereafter snare the obstructing material for positive extraction through the tube.

The object of the invention is to improve the" construction as well as the means and mode of operation of drainage tubes whereby they may not only be economically manufactured, but will be more eflicient in use, easily operated and cleared and unlikely to get out of repair.

A further object of the invention is to provide manually operable means for distending a blood vessel about the entrance to the drainage tube.

A further object of the invention is to provide means for positively engaging and withdrawing obstructing masses of material.

A further object of the invention is to provide a snare operable through the tube for engaging clots or stringy masses.

A further object of the invention is to provide a dislodging and engaging means subject to manual manipulation.

A further object is to provide means for clearing lateral inlet orifices in the drainagetube.

A further object of the invention is to provide an expansible and contractable operating memher subject to manual operation and control.

A further object of the invention is to provide an instrument possessing the advantageous features of construction and meritorious characteristics herein mentioned.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

In the drawing wherein is shown the preferredbut obviously not necessarily the only form of embodiment of the invention, Fig., 1 is a side elevation of the assembled drainage tube forming the subject matter hereof. Fig. 2 is an enlarged perspective View of the intake end of the tube with the snare removed. Fig. 3 is an enlarged perspective view of the snare removed from the tube. Fig. 4 is an enlarged perspective View of the intake end of the tube with the snare in expanded relation thereto. Fig 5 is an enlarged sectional view of a portion of the tube with the snare therein. Fig. 6 is a detail sectional view, showing the snare blades expanded.

Like parts are indicated by similar characters of reference throughout the several views.

The use of a drainage tube for the present purpose is quite old and well known. For illustrative purposes but with no intent to unduly limit the application or scope of 'the invention there is shown in the drawing a drainage tubeof the type shownin patent to Andrews No. 954,494 of April 12, 1910, comprising an elongated conduit portion I having a lateral discharge branch conduit 2. The main tubular conduit I is closed at its outer end by a screw threaded cap or head 3 enclosing a sealing gasket. The cap and gasket are perforated for accommodation of a reciprocatory snare stem as hereafter described. The tubular conduit is open at its intake terminal where it has a slightly contracted orifice 4, about which is formed a thrust seat or annular abutment 5 adjacent to the open terminal of the tube, and is further longitudinally slotted at 6. Such lateral intake slots 6 are relatively long and comparatively wide. Ordinarily four such slots are equally spaced about the periphery of the tube I alternating with unslotted portions of substantially equal extent. It will be understood, however, that a greater or lesser number of slots to accommodate corresponding snare blades may be provided.

Extending axially within the tube I is a reciprocatory stem or rod 1 projecting beyond the terminal cap 3 where it carries a knob 8. At its opposite end thereciprocatory rod carries a cage like head 9 comprising a group of longitudinally disposed laterally spaced flexible blades or wires Hi interconnected at one end to the reciprocatory stem or rod 7 and collectively attached at their opposite end to a thrust head II. The thrust head it is preferably tapered and adapted to extend beyond the end of the tube through the terminal opening 4 when the rod 1 is in its advanced position. In such relation the periphery of the thrust head II will have contact engagement with the annular abutment or seat about the terminal opening 4 while the cage like group of flexible snare members lies within the slotted portion of the tube with such flexible members it) in registry with the respective slots 6. In this condition the tube can be introduced into the vein, which is facilitated by the tapered thrust head H projecting beyond the end of the tube and serving as a pilot. The rod 1 is then retracted by the knob 8 until the expansible head 9 is beyond the outlet branch 2 of the tube which is connected by rubber tubing with a receiver, thus permitting free drainage of blood.

When, however, the blood flow is interrupted by accumulation of fibrin or clots about the intake orifices of the tube, the rod is advanced in the tube and rotatively adjusted until the flexible blades or wires It! are in registry with the lateral slots 6, and the thrust head II is seated against the annular abutment seat 5. Then by applying pressure to the rod knob 8 the cage like head is expanded by longitudinal compression causing the blades or wires i 0, as the case may be, to bow outward through the lateral slots 6. The distention of the members not only serves to clear the slots, by dislodging any deposits which may be clogging the slots, but it also distends the surrounding walls of the blood vessel and relieves the pressure on any accumulation of clots or fibrin, and allowing movement thereof toward the drain tube where they collect beneath the distended bowed blades or wires Ill. Upon release of compression such masses of material are caught beneath the blades Ill and upon retraction of the rod or stem 1 such clots and masses of stringy substance are withdrawn into the tube from which they will pass through the discharge branch 2, leaving the inlet orifices 4 and 6 of the tube unobstructed. The expansible head 9 upon the reciprocatory rod thus serves a threefold purpose, of clearing the lateral slots, distending the walls of the vein to release accumulated material and positively grasping the material for retractive movement into and through the tube, thus insuring a free drainage outlet.

For purpose of limiting expansion of the flexible head 9 and preventing undue distention of the blood vessel about the tube, the rod or stem 1 may be continued within the group of flexible members [0 comprising the expansible head 9 and terminated at a point in spaced relation with the thrust head H, as is indicated at la. As the stem or rod is pressed inwardly subsequently to the contact of the thrust head H against the annular abutment '5 of the tube,

the members 10 are flexed or bent outwardly awash;

through the slots 6 until the extremity of the rod extension Ia contacts the inner side of the thrust head ll, thereby arresting the advance movement of the rod and preventing further flexing of the members If]. By making the rod extension la of different length the degree of expansion may be correspondingly varied.

To facilitate the drainage flow, continuations 6a of the longitudinal slots 6 are provided rearwardly thereof and separated by intermediate bridging portions 61) which serve to stiffen and strengthen the slotted portion of the tube. The flexible blades ID are preferably sufficiently long to extend throughout the combined length of the main slots 6 and extension slots 6a. Such increased length also increases the flexibility of the members H] which as they are expanded through the main slots 6 by their engagement with the ends 6b thereof are induced to assume a substantially compound curvature by which their rear portions are contracted more closely about the rod within the limits of the slot extensions Ga, thereby permitting free ingress of fluids therethrough.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
