Description

Technical Field

[0001] This utility model relates to the field of medical testing auxiliary tools, and in particular to a sputum mixing cup. Background Technology

[0002] Common spittoons such as Figure 1 As shown, the cup is designed in the shape of an inverted frustum, approximately 5 cm high, with a relatively large opening to allow patients to spit sputum into it. However, this type of sputum cup has the following problems: some patients' sputum is highly viscous and often adheres to the inner wall of the cup. After adding digestive fluids to the cup, centrifugation is required to ensure thorough mixing of the digestive fluids and sputum. Figure 1 The sputum cup shown cannot be directly centrifuged, so this invention improves the sputum cup so that it can be convenient to collect sputum samples and can be directly centrifuged, thereby improving the mixing effect of digestive juices and sputum. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a sputum mixing cup that facilitates sputum collection and allows for direct centrifugation.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] A sputum mixing cup includes a cup body, a sampling funnel, and a lid;

[0006] The cup body is cylindrical, and the outer wall at the top of the cup body has external threads.

[0007] The sampling funnel includes a funnel body and a feeding pipe located at its bottom. A connecting pipe is also provided below the outer wall of the funnel body. The connecting pipe is coaxially arranged with the feeding pipe. The inner wall of the connecting pipe is provided with internal threads. When the connecting pipe is threadedly connected to the cup body, the feeding pipe is located inside the cup body.

[0008] After sampling is complete, the lid is used to seal the cup.

[0009] Furthermore, the cup body, sampling funnel, and lid are all made of plastic.

[0010] Furthermore, the bottom of the cup is equipped with a base, and the cup and the base are integrally formed, with the bottom surface of the base being flat.

[0011] Furthermore, a stud is provided at the bottom of the cup body, and the cup body and the stud are integrally formed. A base is threaded onto the stud, and the base is made of metal.

[0012] Furthermore, the top surface of the base is in close contact with the bottom surface of the cup.

[0013] Furthermore, it also includes a discharge pipe, which is made of plastic material with deformable properties. One end of the discharge pipe has an internal thread on its inner wall for threaded connection to the cup body, and the other end of the discharge pipe has a tapered opening.

[0014] Furthermore, it also includes multiple glass beads with a diameter of 4mm-6mm.

[0015] Furthermore, the outer wall of the cup is marked with graduations.

[0016] The beneficial effects of this utility model are as follows: Compared with the sputum cup in the prior art, this utility model sets the body of the sputum mixing cup to be cylindrical, reduces the diameter and increases the height, so that the cup body is similar to a centrifuge tube, so as to facilitate centrifugation; this utility model adds a sampling funnel, which is detachably installed on the top of the cup body, so as to collect the patient's sputum.

[0025] like Figure 2 As shown, this embodiment provides a sputum mixing cup, including a cup body 1, a sampling funnel 2, and a lid 3. All three are made of plastic and are not easily deformed.

[0026] The cup body 1 is cylindrical and used to collect sputum. The outer wall of the cup body 1 has graduations to visually indicate the amount of digestive fluid added. The outer wall of the top of the cup body 1 has external threads for threaded connection to the sampling funnel 2 or the lid 3.

[0027] Among them, such as Figure 2 , Figure 3 As shown, the sampling funnel 2 includes a funnel body 21 and a feeding tube 22 located at its bottom. A connecting tube 23 is also provided below the outer wall of the funnel body 21. The funnel body 21, the feeding tube 22 and the connecting tube 23 are all integrally molded. The connecting tube 23 is coaxially arranged with the feeding tube 22 and is located outside the feeding tube 22. The inner wall of the connecting tube 23 is provided with internal threads. When the connecting tube 23 is threaded to the cup body 1, the feeding tube 22 is located inside the cup body 1. Moreover, there is preferably a certain gap between the feeding tube 22 and the inner wall of the cup body 1, which is convenient for installing the sampling funnel 2 into the cup body 1 and also facilitates the collection of sputum into the cup body 1 along the sampling funnel 2.

[0028] The inner wall of the lid 3 is provided with internal threads. After the sputum sampling is completed, the lid 3 is threaded to the cup body 1 to seal the cup body 1.

[0029] To make it easier to place cup 1 on the countertop, such as Figure 4 As shown, a base 4 is provided at the bottom of the cup body 1, and the cup body 1 and the base 4 are integrally formed, with the bottom surface of the base 4 being flat. To further improve the stability of placing the cup body 1, as shown... Figure 5 , Figure 6 As shown, a stud 11 is provided at the bottom of the cup body 1. The cup body 1 and the stud 11 are integrally molded. The stud 11 is threadedly connected to the base 4, and the top surface of the base 4 is in close contact with the bottom surface of the cup body 1. If the bottom surface of the cup body 1 is flat, then the top surface of the base 4 is flat; if the bottom surface of the cup body 1 is conical, then the top surface of the base 4 is a concave conical surface. The base 4 is made of metal and acts as a weight, which can lower the center of gravity of the sputum mixing cup, thereby improving stability.

[0030] More specifically, such as Figure 8 As shown, the sputum mixing cup also includes a discharge tube 5. The discharge tube 5 is made of plastic material with deformable properties. When the experimenter squeezes the discharge tube 5 by hand, the discharge tube 5 can be deformed. The inner wall of one end of the discharge tube 5 is provided with internal threads for threaded connection to the cup body 1. The other end of the discharge tube 5 is provided with a conical opening 51 for extruding the sample inside the cup body 1.

[0031] The usage method is as follows:

[0032] S1. Install the sampling funnel 2 on the top of the cup body 1, as follows: Figure 6 As shown, the patient spits into the sampling funnel 2, and the sputum is collected into the cup body 1;

[0033] S2. The experimenter places multiple glass beads with a diameter of 4mm-6mm into the cup body 1, removes the sampling funnel 2, and installs the lid 3, as follows. Figure 7 As shown, this facilitates storage and prevents contamination;

[0034] S3. Centrifuge the cup 1 using a centrifuge device; the glass beads disperse the sputum.

[0035] S4. Remove cover 3 and install discharge pipe 5, as follows: Figure 8 As shown, the experimenter gently squeezed the discharge tube 5 by hand, and a drop of sample, approximately 60 μL, dripped from the conical opening 51.

[0036] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
