Abstract
An elongated temperature sensing probe of an electronic thermometer having a movable collar and an elongated probe terminating with a probe tip including a heat sensing element. A disposable cover having an elastic cylindrical side wall mounted on a closed end member is latched to the probe to enclose the tip and surround an elongated portion of the probe. The closed end member has a thin cone-shaped thermal window which is deformed into surface engagement with the probe tip when the cover is mounted on the probe. The probe collar and open end section of the cover have coacting releasable latch structure holding the cover in assembled relation with the probe.

A temperature sensing probe and cover therefor comprising:
- a temperature sensing probe including an elongated tubular member having a first end and a second end, a tip secured to the first end of the tubular member, said tip having a forwardly converging annular side wall, said side wall having an outward convex shape, a temperature responsive element secured to the tip, a body secured to the second end of the tubular member, a cylindrical collar having a chamber accommodating the body, a head secured to the collar surrounding the tubular member between the body and tip, and means surrounding the body and engageable with the collar to bias the collar away from the tip, said head having an annular groove and an annular shoulder facing the groove;
- a cover for enclosing part of the tubular member and the tip, said cover having a body, said body having a generally cylindrical elastic side wall forming a cover chamber accommodating part of the tubular member, an end member of rigid material attached to the body for accommodating the tip, said side wall having an open end section surrounding the head, said open end section having an annular bead located in the groove and engageable with the shoulder to hold the cover in assembled relation with the tubular member and tip, said end member having a forwardly converging annular thermal window section, said thermal window section having a flexible annular wall being deformed into surface engagement with the outward convex shaped side wall of the tip whereby heat from the environment adjacent the thermal window section is transferred through said thermal window section to the tip and temperature responsive element secured therto, said means surrounding the body and engageable with the collar to bias the collar away from the tip being operable to bias the flexible wall of the thermal window section into surface engagement with the convex shape of the side wall of the tip.
A temperature sensing probe and cover therefor comprising:
- a temperature sensing probe having an elongated member, a tip on one end of the elongated member, said tip having a side wall, a temperature responsive element secured to the tip, and means having a head surrounding the elongated member;
- a cover having an elastic side wall forming a cover chamber accommodating part of the elongated member, said side wall having an open end section surrounding the head, said open end section having means cooperating with the head to hold the cover in assembled relation with the elongated member and tip, said cover further having a closed end member of rigid material secured to the end of the side wall opposite the open end section;
- said end member having a flexible annular wall forming an annular thermal window section surrounding a chamber accommodating the tip of the probe, said annular wall being deformed into surface engagement with the side wall of the tip whereby heat from the environment adjacent the thermal window section is transferred through said thermal window section to the tip and temperature responsive element secured thereto.
A temperature sensing probe and cover therefor comprising:
- a temperature sensing probe including an elongated member having a first end and a second end, a tip secured to the first end of the member, said tip having a forwardly converging annular side wall, said annular side wall having an outward convex shape, temperature responsive means secured to the tip, and holding means secured to the second end of the member;
- a cover for enclosing part of the member and the tip, said cover having a body forming a cover chamber accommodating part of the member, an end member of rigid material attached to the body for accommodating the tip, said end member having a forwardly converging annular thermal window section, said thermal window section having a flexible annular wall located in surface engagement with the outward convex shaped side wall of the tip whereby heat from the environment adjacent the thermal window section is transferred through said thermal window section to the tip and temperature responsive element secured thereto, said body having means cooperating with the holding means to hold the cover in assembled relation with the elongated member and tip to hold the flexible wall of the thermal window section into surface engagement with the convex shape of the side wall of the tip.
A temperature sensing probe and cover therefor comprising:
- a temperature sensing probe having an elongated member, a tip on one end of the elongated member, said tip having a wall, temperature responsive means secured to the tip, and holding means mounted on the other end of the elongated member;
- a cover having a tubular elastic side wall forming a cover chamber accommodating part of the elongated member, said side wall having an open end section surrounding the holding means, said open end section having means cooperating with the holding means to hold the cover in assembled relation with the elongated member and tip, said cover further having a closed end member of rigid material secured to the end of the side wall opposite the open end section;
- said end member having a flexible wall forming a thermal window section and a chamber accommodating the tip of the probe, said wall being located in surface engagement with the tip whereby heat from the environment adjacent the thermal window section is transferred through said thermal window section to the tip and temperature responsive means secured thereto.
