Description
Technical Field
The utility model relates to the technical field of slice-making dyeing machines, in particular to a novel large test tube.
Background
In the field of clinical medicine, the existence of pathological changes in a human body is often judged by observing cell slices of various tissues of the human body, and the cell slices are prepared by the following steps: sampling, centrifuging, smearing and dyeing, wherein each step is respectively carried out in a work area separated from each other, a transfer mechanism is required for transferring samples among the steps, and a disposable large test tube is required for sucking and transferring the samples in order to ensure that the samples are not polluted.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides a novel large test tube, which solves the problems in the prior art by arranging a clamping groove on the inner side of a tube opening, additionally arranging a reinforcing rib on the outer side of a sharp nozzle and arranging a U-shaped or O-shaped sharp nozzle at the sharp nozzle.
In order to achieve the purpose, the utility model adopts the following specific scheme:
the utility model provides a novel large test tube, which is characterized by comprising: a test tube body; the test tube body is conical, the upper end of the test tube body is provided with a tube orifice, the lower end of the test tube body is provided with a sharp mouth, and the aperture of the tube orifice is larger than that of the sharp mouth; the inner side of the pipe orifice is provided with a clamping groove for fixing an external suction nozzle;
the tip mouth of the lower end of the test tube body is a U-shaped tip mouth with two inclined sides or an O-shaped tip mouth with one inclined side.
Furthermore, one end of the sharp mouth outside the test tube body is provided with a reinforcing rib;
the strengthening rib is the slice bar-shaped structure that sets up along the test tube outer wall, and the strengthening rib side is stood on the test tube outer wall.
Further, the number of the reinforcing ribs is 4.
Further, a reinforcing rib is arranged on the outer side of the pipe orifice at the upper end of the test tube body.
Further, the clamping groove is an annular groove.
By adopting the technical scheme of the utility model, the utility model has the following beneficial effects:
the utility model provides a novel large test tube, which comprises: the test tube comprises a test tube body, a clamping groove arranged on the inner side of a tube opening, a reinforcing rib arranged on the outer side of a sharp nozzle and a U-shaped or O-shaped sharp nozzle arranged at the sharp nozzle; the problems that the existing large test tube is easy to fall off from a moving mechanism, insufficient in structural strength, easy to bend and incapable of easily puncturing a test sample packaging opening are solved; the strengthening rib that big test tube outer wall set up increases the intensity of big test tube front end to and when big test tube pricked into the reagent bottle lid, open the reagent bottle lid and make the air get into in the reagent bottle, thereby make the sample liquid of big test tube in the reagent bottle easily suck.

Detailed Description
The utility model is further described below with reference to the following figures and specific examples.
The present invention will be described in detail with reference to FIGS. 1 to 8
The utility model provides a novel large test tube, which comprises: the test tube comprises a conical test tube body, wherein the upper end of the test tube body is provided with a tube orifice, the lower end of the test tube body is provided with a sharp mouth 3, and the aperture of the tube orifice is larger than that of the sharp mouth;
the inside of the pipe orifice is provided with a clamping groove 1 for fixing an external suction nozzle, and the clamping groove 1 is an annular groove along the inside of the pipe orifice.
The sharp mouth one end in the test tube body outside is provided with strengthening rib 2, and strengthening rib 2 is the slice bar-shaped structure along the test tube outer wall setting, and 2 sides of strengthening rib stand on the test tube outer wall.
In the present embodiment, the number of the reinforcing ribs is 4, and in actual production, the number of the reinforcing ribs can be various numbers of 2 or more.
The nozzle tip at the lower end of the test tube body has two implementation modes:
1) one of them is shown in fig. 2, 6 and 7, the tip 3 is a U-shaped tip 3a with two inclined sides;
2) as shown in fig. 5 and 8, the nib 3 is an O-shaped nib 3b with one side inclined.
The U-shaped sharp nozzle 3a is formed by performing bilateral symmetrical beveling on the pipe orifice, and the O-shaped sharp nozzle 3b is formed by performing unilateral beveling on the pipe orifice.
