Abstract

Abstract The present invention relates briefly to a sampling instrument for simultaneously drawing of cell-samples and bacteriological samples, preferably from the uterus of animals. The instrument comprises a lead-in tube (2) and an operating rod (3), the samplers (5, 6) being secured to the operating rod. The samplers are a cell-sampler (5) at the leading-in end of the operating rod and a bacteriological sampler (6) on the rod a distance inwards of the cell-sampler (5). Normally, both the samplers (5, 6) are located within the tube (2). The lead-in tube (2) acts on one hand as an aid for the insertion of the samplers (5, 6) and on the other hand as a protection therefore both during the storing of the instrument as well as after sample drawing. Due to the fact that the samplers easily may be separated from the rest of the operating rod and the tube (2) easily is cut into convenient portions and closed at the ends thereof enclosing one or both of the samplers there is obtained an easily transportable capsule which protects the sample from the environment and vice versa.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 156 words
A sampling instrument of disposable type for simultaneous sampling of cell samples and bacteriological samples from the uterus of animals comprising a flexible tube, a rod having an operating end extending outside of said tube and a sampling end extending inside of said tube, said rod being moveable relative to said tube in such a manner that said sampling end can be reciprocated out of and back into said tube, and means attached to said sampling end for taking a first cell sample from said uterus when said tube is inserted into said uterus and said sampling end is moved out of said tube a first distance, subsequently taking a second distinct bacteriological sample from said uterus when said sampling end is moved out of said tube an additional second distance, and for allowing said first and second samples to be moved back into said tube prior to the removal of said tube from the uterus.
Claim 2
Dependent Claim 156 words
A sampling instrument of disposable type for simultaneous sampling of cell samples and bacteriological samples from the uterus of animals comprising a flexible tube, a rod having an operating end extending outside of said tube and a sampling end extending inside of said tube, said rod being moveable relative to said tube in such a manner that said sampling end can be reciprocated out of and back into said tube, and means attached to said sampling end for taking a first cell sample from said uterus when said tube is inserted into said uterus and said sampling end is moved out of said tube a first distance, subsequently taking a second distinct bacteriological sample from said uterus when said sampling end is moved out of said tube an additional second distance, and for allowing said first and second samples to be moved back into said tube prior to the removal of said tube from the uterus.
Claim 3
Dependent Claim 26 words
The sampling instrument of claim 1 wherein said rod includes one or more cutting masks for separating one or more of said samplers from said rod.
Claim 4
Dependent Claim 36 words
The sampling instrument of claim 1 wherein said tube includes one or more cutting marks for separating the portion of said tube, enclosing one or more of said samplers, from the remaining portion of said tube.
Claim 5
Dependent Claim 27 words
The sampling instrument of claim 3 wherein said rod includes one or more cutting marks fracture for separating one or more of said samplers from said rod.
Claim 6
Dependent Claim 21 words
The sampling instrument of claim 3 wherein said tube includes a cutting mark in the portion thereof surrounding said bacteriological sampler.
Claim 7
Dependent Claim 21 words
The sampling instrument of claim 4 wherein said tube includes a cutting mark in the portion thereof surrounding said bacteriological sampler.
Claim 8
Dependent Claim 21 words
The sampling instrument of claim 2 wherein said tube includes a cutting mark in the portion thereof surrounding said bacteriological sampler.
Claim 9
Dependent Claim 21 words
The sampling instrument of claim 2 wherein said instrument is enclosed within a casing of sheet material which is hermetically closed.
