A tissue lumen stent is provided with a body having an elongated tubular configuration and a foreshortened configuration. In the foreshortened configuration, downstream and upstream ends of the body expand radially into downstream and upstream flange structures, leaving a generally cylindrical saddle region therebetween. In some embodiments, the flange structures are non-symmetrical with respect to one another. Systems and methods of using the stents are also disclosed.

The positioning pin is inserted into the wrench positioning pin hole and is inserted into the base positioning pin hole. The punch is inserted into the punch hole and presses the top surface of the outer hexagon of the connecting shaft. The wrench screw comprises a nut, a positioning section and a threaded section, the positioning section is in sliding fit in a screw hole and is limited by the nut, and the threaded section is matched with the connecting shaft.

A liner for a ski boot has a tongue with an outer substantially saddle-shaped generally stiff layer generally conforming to a dorsal surface of a foot, an inner padding layer contacting the dorsal surface and having a first and second portion. The second portion covers at least a part of a dorsalis pedis artery and is softer than the first portion. A support layer is outside the outer layer and at least partially overlaps the second portion. Also provided is a tongue for footwear having an outer substantially saddle-shaped generally stiff layer conforming to the dorsal surface, an inner padding layer contacting the dorsal surface and having a first and second portion. The second portion covers at least a part of a dorsalis pedis artery and is softer than the first portion. A support layer is outside the outer layer and at least partially overlaps the second portion.

The utility model discloses a quick-opening blind plate sealing ring which comprises a body with a saddle-shaped section, a first warped foot, a second warped foot and a third warped foot, the first warped foot, the second warped foot and the third warped foot are connected to the outer wall face of the body, the first warped foot and the second warped foot are oppositely arranged on the lower side of the body to form a first pressed inner cavity, and the third warped foot is arranged on the upper side of the body to form a second pressed inner cavity. An opening of the second pressure-bearing inner cavity faces the high-pressure raw material gas side, and the first pressure-bearing inner cavity is communicated with the second pressure-bearing inner cavity through a flat pressing hole; the first pressed inner cavity and the second pressed inner cavity which are communicated with each other are formed in the upper side and the lower side of the body with the saddle-shaped section, so that the first warping foot and the third warping foot generate upward horizontal pressure and outward horizontal pressure respectively, the body is attached to the sealing face of the quick-opening blind plate more tightly, and the quick-opening blind plate can be quickly opened along with continuous increase of the pressure. The first pressed inner cavity floats upwards to a certain degree, the gap between the blind plate cover and the lock ring can be compensated, and the phenomenon that the blind plate loses efficacy in the using process is avoided.

The utility model provides a saddle-shaped pipe fitting structure, and belongs to the technical field of saddle-shaped pipe fittings. The technical problem that an existing saddle-shaped pipe fitting joint is not convenient enough in butt joint operation is solved. The saddle-shaped pipe fitting structure comprises a saddle-shaped part, a branch pipe is arranged on the saddle-shaped part, an annular blocking shoulder is arranged at the end of the branch pipe, a butt-joint nut capable of freely rotating around the branch pipe is arranged on the periphery of the branch pipe in a sleeving mode, and an annular sealing edge is arranged on the inner edge of the butt-joint nut. And the sealing edge is limited and matched between the saddle-shaped part and the retaining shoulder along the axial direction of the branch pipe. The saddle-shaped pipe fitting is high in structural applicability, and the connecting convenience of the saddle-shaped pipe fitting can be effectively improved.

Newness and distinctiveness reside in the visual features, including shape, configuration and / or pattern, of a SADDLE-MOUNTING BRACKET ASSEMBLY as shown in the accompanying drawing.

The present invention relates to a cushion assembly for a patient interface comprising: an elastomeric seal-forming portion including a membrane with an inner boundary, wherein the elastomeric seal-forming portion comprises: a dome-shaped superior region, a saddle-shaped inferior region, a first support region extending from the saddle-shaped inferior region to the dome-shaped superior region, and an attachment structure configured to prevent the inner boundary of the membrane from being blown outwards away from the plenum chamber due to pressurization within the plenum chamber, wherein the attachment structure comprises a first tie extending between a first interior surface region of the cushion assembly and a second interior surface region of the cushion assembly.

The invention belongs to the technical field of bolt and nut locking, and relates to a bolt and nut locking device. The bolt comprises a bolt head, a bolt column, a nut, a flat washer and a saddle-shaped elastic washer, the bolt head is connected to one end of the bolt column. The nut is in threaded connection with the bolt column. A slot is formed in the flat washer, and one side of the saddle-shaped elastic washer is matched with the slot in an inserting manner; and after one side of the saddle-shaped elastic washer is inserted into the slot, the flat washer and the saddle-shaped elastic washer form a V shape. Compared with a traditional method that a nut is screwed to a bolt head in a long stroke to prevent scattering, the device has the advantages that the flat washer and the saddle-shaped elastic washer are designed to be of the V-shaped structure capable of being combined in an inserted mode, so that the nut only needs to be screwed into a short stroke, enough elastic deformation and friction force can be generated by extruding the saddle-shaped elastic washer, and the temporary locking state is achieved. The process is labor-saving and quick to operate. During formal installation, additional complex operation is not needed, the workload of assembly workers is reduced on the whole, and the working efficiency is improved.

A cushion assembly for a patient interface including an elastomeric seal-forming structure that is shaped to be bisected by a sagittal plane having a line that is tangent to the elastomeric seal-forming structure at a superior tangent point and at an inferior tangent point. A saddle-shaped superior region of the elastomeric seal-forming structure straddles the sagittal plane and includes the superior tangent point. The elastomeric seal-forming structure transitions in a cylinder-shaped superior region from the saddle-shaped region to a dome-shaped superior region offset from the sagittal plane. In addition, an elastomeric wall thickness of the elastomeric seal-forming structure is greater in the cylinder-shaped superior region than in the saddle-shaped superior region and the dome-shaped superior region.
