Apparatus for the alleviation of operative and post operative deep venous thrombosis comprises a flexible pad for enwrappment about a mammalian limb such as a human leg. The pad comprises a first plurality of large, individual, fluid receiving pressure cells alternated with a second plurality of smaller, fluid receiving and releasing ventilating cells. Means are included for supplying fluid pressure to the cells.

A first hollow elongated cylinder has a first inner diameter. One end of the first cylinder is open. The opposite end of the first cylinder is provided with sealed tip adapted to detachably receive a hypodermic needle. A second hollow elongated cylinder has a second and larger inner diameter. One end of the second cylinder is open. The opposite end of the second cylinder has centered therein a circular port with a diameter equal to the first diameter. The cylinders are disposed end to end along ...

A connector for medical tubing comprises two interengaging parts (1, 12). As one part is rotated relative to the other, screw-threads cause a tapered projection (13) to mate with a flared bore (6) to provide a fluid-tight seal. Further relative rotation causes the outer bevelled edge of the outer wall (16) of one of the parts to move further forward to sealingly engage the sloping wall (10) of the other part. The projection (13) and outer wall (16) are connected by a flexible membrane 19 to perm...

A medical apparatus comprising a displaceable vertical column 1 along which there can be slid a support 23 in which an arm 25 is rotatable about a first horizontal axis. Secured to the arm 25 and rotatable about a second horizontal axis parallel to the first horizontal axis, is an examination device which comprises a combination of a radiation source 81 and a radiation detector 83. Said combination is mounted on a C-shaped frame 63 which is displaceable circumferentially about an axis which lies...

Irradiation-sterilizable medical articles molded from a propylene polymer composition in which stabilizers are incorporated. Said composition comprises from 0.01 to 0.4 part by weight of each of a specific hindered amine and a specific phenol or its phosphite ester compound incorporated per 100 parts by weight of a propylene polymer with a weight-average molecular-weight to number-average molecular-weight ratio of 5 or below. The above-mentioned composition may additionally contain a sorbitol de...

The eyelet of a snap fastener conductor extends both through an adhesively coated supporting sheet and a gel pad whereupon a flange on the eyelet cooperates with the gel pad to form a cuplike cavity in which electrolyte gel is placed. The supporting sheet is formed from a substantially moisture and water vapor impervious material and cooperates with a cover that is also substantially moisture and water vapor impervious having a cavity receiving the gel pad to prevent gel dry out.

The apparatus comprises a first apparatus part and a second apparatus part which is disposed on and extends outward from the first part. The second part is movable with respect to the first part between an attracted position, in which it is extended to a predetermined extent, and a retracted position, in which it is extended to a lesser extent. The apparatus also comprises a security device disposed on at least one of the first and second parts. This device includes a magnetic device for exercis...

A medical sleeve wherein a knitted sleeve length is provided to extend from a snug location of the lower end adjacent the wrist of a wearer all along the entire length of an arm to the shoulder and wherein a strap is provided for hooked-up engagement through snap means to connect the sleeve to a brazier strap, which device is useful after a masectomy.

A medical syringe adapted for one hand operation in both aspiration and injection modes, employs an elongated hollow cylinder having at one end a first external flange extending at right angles to the axis of the cylinder and an opening for receiving a piston, the opposite end of the cylinder being adapted to detachably receive a hypodermic needle. The syringe also employed a piston extending slidably through said opening and being aligned with and centered on the axis of the cylinder, there bei...

A method and article for medical diagnosis and/or treatment of body disorders, comprising a sleeve unit 10 insertable in a natural body vessel to isolate material flowing into the vessel from direct contact with the interior surface of the vessel. When applied to the treatment of obesity, the sleeve is disposed along a zone in the digestive tract 32 to interfere with the digestive or absorptive function of that zone and thereby reduce net caloric intake.
