A fetal scalp monitor is disclosed that enables a medical professional to monitor the well-being of a fetus in utero. The fetal scalp monitor has a main body, with a central core having a temperature sensor, conductive dome, grounding ring, and tocodynamometer. The main body also has at least one adhesive portion to facilitate the attachment of the device onto the scalp of a fetus, and a plurality of concentric rings to militate against amniotic fluids from entering the adhesive portion. The vital signs of the infant and conditions inside the uterus are then transmitted, either wired or wirelessly, to a fetus monitoring device.

A vaginal speculum and side wall retractor allows clinicians to visualize the cervix and upper vagina by retracting vaginal walls simultaneously. This device is comprised of a handle, a mobile introducer allowing the device to comfortably be inserted vaginally, and a lower blade capable of stabilizing the cervix and a body containing the side wall retractor. This retractor is comprised of a rolled-up sheet of transparent plastic which can be opened through a rotating shaft countersunk in the body of the base. A friction or sprocket gear allows the rotating shaft to open and close the plastic side wall retractor as well as completely unwinding the transparent plastic sheet so that the device can be removed while leaving surgical instruments in the vagina. The rotating shaft serves as a light guide and brings light from the knob, which contains an LED, into the rolled-up sheet during examinations.

A center marking assemblage or kit consisting of a stylus retaining quill having an upper end and a lower end; a stylus having an upper driving end and a lower scribing end, the stylus being slidably mounted within the stylus retaining quill, a group of differently sized scribing end centering guides, each guide among the group having a lower circular diameter matching a common drill bit size; and consisting of quick disconnect couplings integral with the lower end of the stylus retaining quill and with the upper ends of the scribing end centering guides, such couplings allowing such guides to be selectively and alternately attached to and removed from the lower end of the stylus retaining quill.

Center scribing kit for use with drilling templates

The present invention relates to a method and an assembly (10) for detecting dilation of a cervix (74) of a pregnant female (78) at the onset of labor. The assembly (10) includes a ring-shaped element (16) in series with an enclosure (12) which encircles the cervix (74). The enclosure (12) contains a readily detectable fluid or particulate material (14). When the cervix (74) dilates at the onset of labor, the force of dilation is transmitted by the ring-shaped element (16) of the assembly (10) to the enclosure (12) and opens the enclosure (12) causing release of the material (14). The assembly (10) also includes a series of friction tabs (18) to keep the assembly (10) in place on the cervix (74). The method involves selecting an appropriately sized assembly (10), placing the assembly (10) on the cervix (74) of the pregnant female (78), and detecting the release of the material (14) which signals that labor has begun.

A method of making a self-capping needle and catheter assembly (10) includes placing a needle hub (16) and cap (34) on a pin with the pin extending through the passageways (24, 35) thereof. Two sheets of polymeric material (62) are placed about the hub (16) and the cap (34) with their edges welded together producing a sleeve (64) connected between the hub (16) and the cap (34). The sleeve (64) is then permanently stretched to a predetermined length. The cap (34), hub (16) and sleeve (64) are then placed on a needle (28) and the cap (34) is moved against the hub (16) folding the sleeve (64) therebetween for reception of the catheter assembly (14).

A disposable needle assembly (10) includes a hub (16) for connecting the assembly (10) to a fluid conduit, the hub (16) including a passageway (24) extending therethrough. A hollow needle portion (28) is in fluid communication with the passageway (24). A cap (34) has a neutral position along the needle portion (28) proximate to the hub (16) for exposing a length of the needle portion (28) and an extended position for capping the distal tip (32) of the needle (28). The cap (34) is reversibly seated in engagement with a catheter assembly as the needle portion (28) is disposed within a passageway of the catheter assembly whereby removal of the needle portion (28) from the passageway of the catheter assembly moves the cap (34) to the extended position capping the distal tip (32) as the cap (34) is unseated from the catheter assembly. The invention further provides a method of catherizing a patient using a disposable needle assembly (10).

A digital dispenser aid device (10) of the type for use with a syringe (12) includes a housing (24). The syringe (12) can be fixedly mounted within a chamber (28) within the housing (24). A body member 54 includes a recessed portion (56) retaining the cap portion (22) of a plunger (20) therein. The body member (54) is moveable for drawing the plunger (20) of the barrel (14) to draw medicant into the barrel (14). A digital readout display is operatively connected to the body member (54) for projecting a digital output quantitating the amount of fluid drawn into the barrel (14) by movement of the plunger (20) axially out from the barrel (14).

A surgical glove (10) includes a ventral side (12) and a dorsal side (14) integrally connected thereto. The sides (12,14) include a thin layer (16) of stretchable air and water impermeable material and the dorsal side (14) includes a layer (18) of flexible armor (18) embedded in the stretchable air and water impermeable material (16). A method of making the surgical glove (10) includes the steps of dipping a mold shell (24) having the configuration of a human hand with a ventral side and a dorsal side (30) into a liquid (34) which is curable to the stretchable air and water impermeable material (16). A hand shaped layer (18) of the flexible armor is disposed on the dorsal side (30) of the shell (24) prior to curing the liquid (34). The shell (24) is dipped into the liquid (34) a second time to embed the fiber (18) within the liquid (34). Finally, the liquid ( 34) is cured to the stretchable air and water impermeable material (16).

A disposable needle assembly (10,10',10') includes a hub portion (12,12',12') and a hollow needle portion (22,22',22') having a distal tip (26,26',26'). A cap (28,28'28') has a neutral position along the needle portion (22,22',22') proximate to the hub portion (12,12',12') and an extended position for irreversibly capping the distal tip (26,26'26'). A tether (34,34'34') connects the cap (28,28'28') to the hub portion (12,12'12'). The cap (28,28'28') includes a pocket for locking the cap (28,28'28') over the distal tip (26,26'26') when the cap (28,28'28') is in the extended position.
