[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-5 The first embodiment of the present invention provides a sterile negative pressure sampling cup including: a cup body 1, which is a memory air bag, and a cup rim 11 is arranged at the cup mouth of the cup body 1; a probe assembly 2, which includes a cover ring 21, and the cover ring 21 is a circular ring structure, and the two ring openings of the cover ring 21 can be sleeved in the cup rim 11, and a round cover 22 is installed in the middle of the inner circle of the cover ring 21, and a suction port 23 is opened in the middle of the round cover 22, and a suction head 24 is connected to the suction port 23; a cup cover 3, and the cup cover 3 can be detachably installed on the cup rim 11.
[0029] Specifically, the utility model provides a sterile negative pressure sampling cup, which completes the storage of samples through the cup body 1. The cup body 1 with a memory airbag structure can absorb the sample through the cup mouth by pinching the hand. The cup edge 11 is used to install the cover ring 21. The two ring openings of the cover ring 21 with a circular ring structure in the probe assembly 2 can be sleeved in the cup edge 11. The round cover 22 is arranged in the middle of the inner circle of the cover ring 21, which is the waist. The suction port 23 in the round cover 22 and the suction head 24 on the suction port 23 can absorb body fluid samples such as drainage fluid and urine, and can also dig solid feces samples. When it is necessary to absorb liquid feces, the suction head 24 is directed toward the outside of the cup body 1 to sleeve the cover ring 21 on the cup edge 1 1, hold the cup body 1 and squeeze the cup body 1, the memory air bag of the cup body 1 returns to its original shape, and generates suction to suck the drainage fluid, urine and other body fluid samples into the cup body 1, and then a ring opening of the cover ring 21 with a suction head 24 is sleeved on the cup edge 11 to complete the sampling and storage of the drainage fluid, urine and other body fluid samples. When solid feces samples need to be taken, the cover ring 21 can be held and the suction head 24 is used as a sampling rod to dig the feces samples. When the sampling work is completed, the disposable probe assembly 2 can be discarded, and the cup cover 3 is covered on the cup edge 11 to complete the sampling and collection work, and complete the sampling and storage of the solid feces samples. The device has a simple structure, and can complete the sampling of samples of different forms through the suction head 24. It is simple to operate and has a wide range of applications.
[0030] In some possible implementations, the cup body 1 is made of highly transparent silicone material.
[0031] Specifically, the highly transparent silicone material has a transparent property, so medical staff can better observe the color and sampling quantity of feces and other samples, and the highly transparent silicone material has better memory rebound performance. When medical staff press it, the shape of the cup body 1 returns faster and the suction is stronger, further improving the efficiency of liquid sampling. In addition, the highly transparent silicone products also have excellent high temperature resistance and corrosion resistance, which can prevent the cup body 1 from being corroded due to long-term use.
[0032] In some possible implementations, the two ring openings of the cover ring 21 are sleeved inside the cup rim 11 through threaded connection.
[0033] Specifically, the threaded connection is tighter, preventing the outflow of samples such as fecal samples and drainage fluid, and the threaded connection is more secure. The two ring openings of the cover ring 21 are not easy to fall off, and the threaded connection is more convenient for replacing the two ring openings. When different ring openings of the cover ring 21 need to be used, it is easier to disassemble and replace.
[0034] In some possible implementations, the suction head 24 is a conical structure.
[0035] Specifically, the wider end of the suction tip 24 is connected to the suction hole, and when in use, the narrower end of the suction tip 24 is connected to the catheter to absorb body fluid samples such as drainage fluid and urine. The conical structure has higher transmission efficiency, the wide mouth facilitates the discharge of fecal samples into the cup body 1, and the narrow mouth is easier to connect with the catheter. The narrow mouth increases the suction force in the cup body 1, further improving the efficiency of liquid sampling.
[0036] In some possible implementations, a hole cover 25 is detachably connected to a surface of the suction port 23 opposite to the suction head 24 .
[0037] In some possible implementations, the hole cover 25 is installed on a side of the suction port 23 opposite to the suction head 24 through a threaded connection, and a knob is installed on the hole cover 25 .
[0038] Specifically, when one end of the suction tip 24 is inserted into the cup body 1, the hole cover 25 can be closed to prevent the built-in fecal sample from flowing out. When the suction tip 24 is needed to scoop out solid fecal samples, the hole cover 25 can prevent samples such as fecal samples and drainage fluid from falling out of the suction tip 24; the threaded connection is tighter, making it less likely for the fecal sample to flow out, and the knob of the hole cover 25 facilitates the opening and closing of the hole cover 25.
[0039] In some possible implementations, the cup cover 3 is detachably mounted on the cup rim 11 via a threaded connection.
[0040] Specifically, the threaded connection is tighter, which prevents fecal samples from flowing out, and the threaded connection is more secure, so the cup cover 3 is not easy to fall off, which facilitates the opening and closing of the cup cover 3.
[0041] In some possible implementations, a limiting ring 26 is fixedly installed on the bottom of the cup body 1 .
[0042] Specifically, the limiting ring 26 has a limiting effect on the sleeve connection of the cover ring 21 on the cup rim 11. When the cover ring 21 sleeves one of its ring openings into the cup rim 11 as needed, the limiting ring 26 plays a certain limiting role to prevent the cover ring 21 from sleeved too deeply on the cup rim 11 and affecting its removal.
[0043] In some possible implementations, scale lines are marked on the cup body 1 for measuring the volume of the sample in the cup body 1 .
[0044] Specifically, scale lines are set on the outside of the cup body 1 made of highly transparent silicone material, so that medical staff can more accurately measure the volume of samples such as fecal samples, drainage fluid and body fluids in the cup body 1, making it convenient for medical staff to take the right amount of samples.
[0045] Finally, it should be noted that the above embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited thereto. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above embodiments within the technical scope disclosed by the utility model, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiment of the utility model. They should all be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes.
