Description

A device for collecting cecal contents in the nutrition research of equine animals

technical field

The utility model relates to an experimental device, in particular to a cecal content collection device used in the nutrition research of equine animals.

Background technique

The cecum is the key object of research on the nutrition and digestive physiology of equine animals. The determination of some indicators of the cecal contents (cecal fluid and cecal chyme) in animal nutrition experiments is a necessary means to understand the internal environment of the cecum (cecal pH, VFA, ammoniacal nitrogen, etc.) and the digestion of the cecum. Cecal microbial inoculation with cecal fluid or cecal digesta is sometimes required. The characteristics of cecal fluid and cecal chyme are that they contain cecal microorganisms and volatile substances (ammonia nitrogen and VFA), and the distribution in the cecum is not uniform. Therefore, when collecting samples, we must strive to quickly and accurately obtain representative sample. Therefore, the collection of cecal fluid and cecal digesta is an essential operation technique for animal nutrition researchers.

At present, ordinary rubber tubes, ladles, or PVC tubes are commonly used to collect cecal contents of equine animals in animal nutrition experiments. The disadvantages of these tools are that the collection is labor-intensive, difficult to operate, irritating to animals, and difficult to collect representatives. Sexual samples, etc. Some devices require artificial inhalation to generate negative pressure, and the operator accidentally sucks intestinal contents into the mouth, which is very unhygienic and unhealthy. At the same time, some special catheters need to be imported from abroad, and the price is very expensive, generally 800-2000 yuan, but the effect is very general and difficult to operate. The most critical problem is that this kind of catheter can only collect the liquid part of the cecum contents It is not easy to obtain representative samples. At the same time, this kind of catheter also pollutes the sample because it is not easy to clean.

The vacuum negative pressure generator is a medical suction ball with a volume of 300ml.

Preferably, the sampling head is a cecal fluid sampling head, the cecal fluid collecting head is a hard plastic tube with a plug installed at one end, and sieve holes are evenly distributed on the cecal fluid collecting head.

Preferably, the sampling head is a cecal content collection head, and the cecal content collection head is a straight pipe.

Preferably, the sample storage bottle is any container that can be installed on a standard No. 7 rubber stopper, such as a laboratory standard caliber Erlenmeyer flask and a plastic bag.

The utility model has the following beneficial effects:

The cost is low, and the cost of each set is about 60 yuan, which is less than 5% of similar products. Easy to operate, the device uses a powerful suction ball as a negative pressure generating device, no electricity is needed, and sufficient negative pressure can be generated by hand. The transparent medical silicone tube is used as the sampling tube. The outer wall of the silicone tube is smooth and has no irritation to animals. The good and moderate elasticity of the tube allows the tube to advance along the curved digestive tract. The silicone tube has high transparency and the sample can be seen in the tube. The movement of the pipe can be easily determined when the pipeline is blocked. The whole device is transparent, intuitive, easy to clean without leaving any dead space. It is convenient to replace the sampling point, which is conducive to obtaining representative samples. Good versatility, the storage bottle is easy to replace, as long as it is a container with a rubber stopper, it can be used as a storage bottle.

Detailed ways

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, the utility model embodiment provides a kind of cecum content collection device used in the equine animal nutrition research, and this device is made up of sampling head 1, sampling tube 2, long connector 3, short connector 4, double Hole rubber plug 5, sample storage container 6, air guide tube 7, vacuum negative pressure generator 8, the sampling tube 2 is a transparent medical silicone tube, length 80cm, outer diameter 1.4cm, inner diameter 1.0cm, the long connector 3 And the short connector 4 is a transparent hard plastic short tube with different lengths, the length of the long connector 3 is 10cm, and the length of the short connector 4 is 5cm, and the long connector 3 is connected with the short connector 4 and connected with the The airway 7 is connected to each other. The airway 7 is a transparent medical silicone tube with a length of 30cm, an outer diameter of 1.4cm, and an inner diameter of 1.0cm. The vacuum negative pressure generator 8 is a medical suction ball with a volume of 300ml.

The sampling head is a cecal fluid sampling head, the cecal fluid collecting head is a rigid plastic tube with a plug installed at one end, and sieve holes are evenly distributed on the cecal fluid collecting head.

The sampling head is a cecal content collection head, and the cecal content collection head is a straight tube.

The sample storage bottle is any container that can be installed on a standard No. 7 rubber stopper, such as a laboratory standard caliber Erlenmeyer flask and a plastic bag.

In this specific implementation, when the contents of the cecum have been sucked out and need to be collected, one end of the short connector 4 of the double-hole rubber stopper 5 is connected to the sample storage container 6 .
