Description

DESCRIPTION

LABORATORY DEVICE FOR COLLECTION

OF ANIMAL SAMPLES

Technique field

The present description refers to sampling in the veterinary field.

Background

The collection of samples, in particular of faeces and urine, for care and research in animals is of great importance to check and monitor the condition of animals as well as to evaluate results of experimental procedures, for example, in biomedical research, and also for the preclinical development of drugs, therapeutic compounds, metabolic and phenotypic studies in developmental biology, neurosciences, cancerology, etc.

At present there is no easy, inexpensive and effective method for sampling in animals, such as rodents.

For the collection of 24-hour urine samples for rodents for experimental purposes, metabolic cages are used. A metabolic cage consists of a receptacle adapted for the collection of faeces and urine from animals for experimental purposes. Metabolic cages are generally designed so that urine mixes with the animal's feces in the collection procedure and is therefore not effective. Another drawback of conventional metabolic cages resides in the stress applied to the animals prior to sample collection.

Techniques have also been developed for taking urine samples that consist of pressing the animal's bladder to stimulate urination. This technique, however, can cause ulcers in the abdomen of the animal due to the applied pressure, and may even require treatments that can influence the results of the analysis of the samples and, consequently, of the ongoing investigation.

Another known technique used to collect urine samples is cystocentesis, which consists of puncturing the animal's bladder to extract the urine. It is, again, a technique that is invasive for the animal, which is undesirable.

The known proposals, in general, in addition to being invasive, have a low efficiency in terms of the volume of urine obtained since they are individual. Furthermore, they do not prevent cross-contamination of samples and therefore do not provide sufficient efficiency for reliable analysis and experiments.

Therefore, an effective and simple alternative to the devices and techniques known up to now is needed that at least partially solves the drawbacks of the state of the art, so that it is possible to collect urine and faeces from animals in isolation for fast and efficient analysis.

DESCRIPTION

We present here a laboratory device for collecting samples from animals with which it has been proven that the deficiencies found in the devices that have been used up to now are solved for the same purpose and also provides other important advantages, as shown you will see hereinafter.

As used herein, the practitioner of this laboratory device is a research user or caregiver who can perform animal stool and urine sampling operations for care and research in order to monitor and record the status of the animals. and evaluate results of experimental procedures.

The described laboratory sample collection device comprises a base body with an interior space. This base body can be made of any suitable rigid material, such as, for example, plastic. It may be preferable that at least the base body of the laboratory device is made of a disposable material. It may also be preferable that at least the base body is made of a transparent material. Other types of materials are possible, as long as they are resistant and allow adequate hygiene.

The base body of the laboratory device can have any suitable dimension to adapt to the animal to be examined. In particular, the dimensions of the base body can be adapted to rodents such as, for example, rats, mice, hamsters, guinea pigs, etc. and also other species such as rabbits, goats, and pigs, among others. Other animals to be examined with the device described are not ruled out here.

On the other hand, since, as will be seen below, the present laboratory device allows a plurality of animals to be sampled simultaneously, the dimensions of the base body can be any depending on the number of animals to be sampled.

The interior space of the base body is adapted to house at least one sample collector for sampling an individual animal. Preferably, a plurality of sample collectors may be arranged in the interior space of the base body. This allows a simultaneous collection of urine and feces from multiple animals arranged in each of said sample collectors.

For this, each individual sample collector is made up of a container made, for example, of rigid plastic material with a parallelepipedic configuration, adapted to receive, inside, urine from an animal. Other materials and shapes are not ruled out. Each individual sample collector also includes an upper grid adapted so that the animal is arranged on it, for the reception of its faeces. Optionally, if required, a filter medium for urine can be included.

The upper rack of each individual sampler is preferably a metal mesh, made, for example, of aluminum or stainless steel, although other suitable materials are possible. Said upper grid is configured to act as a separator for faeces and urine from the animal. In particular, the upper rack is designed to retain the animal's feces and, at the same time, allow its urine to fall into the collector container. In this way, the animal's feces and urine samples can be collected separately avoiding possible cross-contamination of the samples, which is undesirable.

The described configuration is highly efficient and simple. This is important since, until now, this could only be achieved with very high cost metabolic cages designed for a single animal.

Each individual collector can also have a protective frame arranged on the above-mentioned upper grid, surrounding it peripherally. Said protective frame can be made of the same material as the collector container, preferably plastic, or of a material other than plastic or a material different from the material of the collector container. The protective frame is configured and arranged to prevent direct contact of the animal or the professional with the upper grid of the collector, avoiding damage. In one example, the protective frame may have snap fit members for attachment of the protective frame to the sample collector container, with the top grid sandwiched between the protective frame and the sample collector container.

In a preferred example, the interior space of the base body is compartmentalized, that is, it has a plurality of compartments, two or more, intended to each house an individual collector. To define said plurality of compartments, the base body can include at least one dividing wall arranged in the interior space of the base body. In one example, one or more longitudinal partition walls and / or one or more transverse partition walls may be provided dividing the interior of the base body into said plurality of compartments to house corresponding individual manifolds, as indicated. The one or more partition walls defining the compartments within the base body of the device may be attached to an interior portion of one or more surfaces of the base body by any suitable means known in the art, such as gluing, riveting, soldier, etc. Although these and other attachment means are not ruled out, it is nevertheless preferable to arrange said one or more dividing walls on the base body so that they can be removed therefrom. For this, in a preferred example, guide elements are arranged inside the base body, for example U-shaped elements, configured to slide into said one or more dividing walls in a removable manner. . Said guide elements allow the assembly and disassembly of one or more dividing walls in a quick and simple way, facilitating and speeding up cleaning, maintenance and repair operations of the device.

As previously indicated, one or more dividing walls divide the interior of the base body into a series of compartments to house corresponding collectors. individual. Each individual manifold is arranged in each compartment so that it is temporarily coupled therein by any suitable means. For example, each individual manifold can be engaged in each compartment by friction, pressure, releasable locking of the mechanical type, magnetic, etc. by any other appropriate means, preferably at the bottom of the base body. Regardless of the type of coupling of each individual manifold to the base body of the device, the individual manifolds can be removed from the device when desired or required. An example of coupling the individual manifolds is through two angled stops arranged at the bottom of the interior of the base body so that, when the individual manifold is mounted on the base body, said stop elements are in contact. with opposite corners of the collector container, ie, at least partially surrounding it, temporarily holding it in position for sampling.

The base body can include a top cap. Said lid is intended to prevent animals from escaping from the laboratory device while they are inside it. The lid is a ventilated cover, that is, it allows the entry and exit of air from outside the device, which guarantees adequate conditions while taking samples. The upper cover of the device can be independent from the base body, for example, arranged to be coupled to the upper part thereof by sliding, or it can be hinged to the base body by any appropriate means to tilt relative to it. A protective frame can be arranged on the upper cover to avoid contact between the animal and the professional with the grid and thus guarantee their safety.

On the outside of at least one side wall of the base body, one or more handles can be arranged to comfortably manipulate the device. It is also envisaged, in some cases, that the base body incorporates at least one external housing. The external housing can be adapted to house identification cards, documents, and / or similar objects. Said external housing may be transparent to facilitate a visual examination of objects, eg cards, contained within.

In some cases, liquid detection means may be provided. Said liquid detection means are intended to detect the presence of urine in a container of at least one sample collector housed inside the base body of the device. The liquid detection means comprise at least one liquid sensor which is preferably mounted below a container of at least one of the collectors of samples. In particular, the liquid sensor can be arranged, for example, in a lower part of each individual sampler so that it covers the entire base or at least a relevant part thereof. In this way, when urine from the animal falls to the bottom of the individual sample collector, the sensor detects the presence of urine and a warning is activated, for example, a red light on the outside of the box, below the external housing mentioned above. , to inform the practitioner that a urine sample is available in the individual collector.

The liquid sensor can be a contact sensor. Other types of sensors to detect the presence of urine are possible. As indicated, the warning that activates the sensor of the liquid detection means can be a light signal, for example, a warning light, for example, of the LED or other type, arranged below the external housing, such as has been explained, red or other. However, alternatively or additionally, the prompt that activates the urine sensor may be an audio signal, a text message, a graphic message, or a combination of one or more of the foregoing. Said warning that activates the sensor of the liquid detection means as an indication that a urine sample is available is of great help to the professional, since it is usually more difficult to appreciate the presence of urine than the presence of feces. Once the urine has been collected by the professional, the warning is deactivated, that is, the light turns off and / or the audio signal stops sounding and / or the message disappears or changes, depending on the type of warning in question.

The liquid sensor can work with a rechargeable battery, for example. However, other power sources are contemplated, such as grid connection or even solar power sources. The base body includes a double bottom configured to house at least the wiring of the liquid detection means. The double bottom of the base body can also be adapted to contain the sensor power supply battery, if this type of power supply is used.

With a laboratory device such as the one described, it is possible to carry out the collection of animal samples in a multiple and instantaneous way, that is, it allows the collection of urine and feces samples from various experimental models of mice or other animals of collectively and simultaneously.

The collection of urine and stool samples with the proposed laboratory device that has been described is advantageously carried out in a non-invasive manner, without applying any stimulus. external to the animal. In this way, the animal welfare that is being analyzed is ensured. This advantageously allows reducing stress, as well as pain and suffering on the animal so that its health and well-being are not compromised. An important advantage derived from the fact that, with the laboratory device described, no external stimulus is applied to the animal and the collection of samples is carried out in a non-invasive way is that a greater volume of urine can be obtained in a single void compared to other conventional devices, since the animal urinates naturally without any damage. By way of example, with the present device a urine volume of the order of 800-1000 ^ L in polyuric mice and 150-200 ^ L in healthy mice can be obtained, which can be up to 10 times more than with abdominal massage techniques.

With the configuration that has been described, it has been found that the sampling is highly efficient since it allows the collection of urine samples of high quality and purity since it is not contaminated in the collection process. Obtaining high-purity urine samples enables reliable research data. With the present device, the collection of urine and feces is carried out in a very simple way and in a very short time.

The present device is also easy to use for the collection of feces. First, the animal is removed and subsequently, with the help of a forceps, for example, the desired stool samples are collected. The device is also easy to use for urine collection. First, the metal screen, free of feces, is removed and, with an interchangeable tip pipette, the urine is collected and placed in a tube for later storage. Once urine and stool samples have been collected, all compartments and components can be cleaned, disinfected, and used for subsequent sample collection.

Collectively collecting samples from various animals takes advantage of the biological characteristic that, due to the fact that animals are in close proximity to each other, when one animal urinates, in most cases, the others tend to do so immediately afterward. for what is known as the “domino effect.” This allows to reduce the waiting time and to collect the samples more quickly, unlike the known conventional metabolic cages where this effect is not achieved and the urine is normally contaminated with feces.

In the lower part of the base body of the laboratory device described, wheels of any suitable type can be arranged to facilitate movement and transportation of the same. One or more of said wheels can incorporate a brake mechanism to prevent their movement and thus guarantee a stable position during sample collection.

It may be advantageous to include a suction mechanism to collect the urine. Such an aspiration mechanism may be suitably designed to direct the collected urine into a suitable container for storage.

It is also envisaged that the base body can include, on a side wall thereof, an automatic stool collection system.

The operation of the described laboratory device can be controlled by a computer application, for a mobile and / or desktop device, which allows information on the target animal to be recorded, such as weight, body temperature, images, etc. Said information on the target animal can be associated with a date and time when said information was obtained, which can be associated individually with each animal. That is, the computer application identifies each compartment of the present laboratory device and each animal that may be present in it. The information can be subsequently processed in combination with an identification system for each animal associated with each compartment of the interior space of the base body where the sample collectors are housed.

In other examples or in combination with the previous examples, information regarding the temperature of each analyzed animal can be obtained, for example, through a body temperature sensor. Said body temperature sensor is capable of obtaining, without contact, for example by infrared, the temperature of the animal from which the samples are to be collected. Said body temperature sensor is capable of registering temperature values for each animal and sending them to a processing unit for further processing. The temperature sensor can be arranged, for example, on an internal wall of the base body, at the height of the animal.

In other examples or in combination with the previous examples, the information regarding the weight of each analyzed animal can be obtained, for example, through a system for measuring the body weight of the animal whose values obtained are recorded and subsequently processed. A separate system can be included to measure urine weight and urine stool weight. The obtained value is subsequently sent to a processing unit for further processing.

In other examples or in combination with the previous examples, the device described can incorporate a system for detecting and analyzing substances in feces, such as occult blood in feces, presence of mucus, toxicity among others. This data is sent to a processing unit for further processing. It is also envisaged that a system for the detection of substances and urinalysis can be incorporated that allows to detect their presence and values present in the urine such as, for example, hematuria, albumin, creatinine, urea, determine if there is infection, drugs, levels of toxicity between elements present in urine, etc. Data for each animal is recorded and subsequently sent to a processing unit for further processing.

In other examples or in combination with the previous examples, the images of each analyzed animal can be obtained through a suitable image capture device. The image capture device may be capable of obtaining images and / or videos of each animal in each compartment. The image capture device can be arranged on an internal wall of the base body, in the compartment where the animal is housed. The images or videos obtained are recorded and subsequently sent to a processing unit for further processing.

An automatic piercer may be included in each compartment of the device described to perform an individual piercing in the ears of the animals. The automatic perforator can be remotely controlled from a computer application.

In each compartment of the present device, a motion detector capable of recording movements of each animal housed in the device can be arranged. The motion detector allows observing the behavior of the animal and detecting possible stereotypes that can be interpreted as abnormal behavior. The information obtained by the motion detector can be sent for later analysis by a computer application.

In other examples, the device described may incorporate a device for the automatic implantation of subcutaneous microchips to the animals tested. Saying implantation device can be remotely controlled from a computer application.

It may be advantageous to include an immobilization mechanism to immobilize each animal in each compartment. Said immobilization mechanism can also be remotely controlled from a computer application.

The incorporation of a device that allows substances to be administered subcutaneously independently to each animal can also be envisaged. Said device can be remotely controlled from a computer application.

It is not ruled out to include an automatic device for the extraction of individual blood from each animal simultaneously in each compartment. Said blood collection device can also be remotely controlled from a computer application.

The present device can include, if required, a system for administering oxygen, drugs or analgesia by inhalation route to each animal in each compartment on an individual basis. Said administration of oxygen, drugs or analgesia can be remotely controlled by a computer application capable of assigning a dose to each animal housed in each compartment and administering it simultaneously independently.

The laboratory device described can incorporate a device to perform electrocardiograms individually for each animal in each compartment. The result is sent to a computer application. The data could be printed on paper if required.

In some applications, a device could be included to take the blood pressure and measure the heart rate of each animal individually, and record the data obtained with date and time of each animal to be sent to a computer application.

Other means of data collection such as an automatic digital microchip reader capable of sending data read individually from each compartment and animal that is being analyzed in the laboratory device are not ruled out.

The registration and transmission of information can be done automatically, without professional intervention. The computer application mentioned above for each Optional device for data collection that has been described may be different or a global computer application capable of managing all the information received from the device.

Other objects, advantages and characteristics of examples of the present laboratory device for collecting samples from animals will be clear to the person skilled in the art from the following description, or can be derived from practicing the same.

DETAILED EXHIBITION OF AN EXAMPLE

The particular non-limiting example of the present laboratory device for collecting animal samples described below finds advantageous utility in animal research in many fields such as biochemistry, nutrition, nephrology, urology, toxicology, metabolism, and physiological studies among others. and veterinary use.

With the laboratory device of the example described, it has been found that it is possible to collect samples from several animals instantaneously, at the same time, in a very simple and efficient way, and with a considerable saving of time, as will be seen below. continuation.

The laboratory device for collecting samples from animals that is described in accordance with the non-limiting example shown in Figures 1 to 3 has been designated collectively by the reference number 100 and will hereinafter be referred to as multi-collector 100 The multi-collector 100 comprises a base body 110 manufactured in a colored, translucent or transparent disposable rigid plastic. The base body 110 of the multi-collector 100 has a box-shaped rectangular base parallelepipedic geometry 40 cm long, 14.5 cm high, and 25 cm wide, which defines an interior space 120 adapted to accommodate various collectors of 200 individual samples. Other shapes and dimensions are possible.

In the particular non-limiting example illustrated in Figures 1-3, the interior space 120 is adapted to house six individual collectors 200 for the simultaneous collection of urine and feces from multiple animals. In this particular example of the multi-collector 100, each individual sampler 200 has a rectangular parallelepiped geometry 12.50 cm long, 3 cm high, and 9.50 cm wide. Other shapes and dimensions are possible.

Each individual sampler 200 allows to receive an animal, such as a rodent, for example, a rat, a mouse, a hamster, a guinea pig, etc. The base body 110 of the multi-collector 100 can have other dimensions to take samples of other species, such as rabbits, goats, and pigs, among others, for example. Therefore, the dimensions of the base body 110 of the multi-collector 100 will depend on the type and number of animals to be sampled.

The sample collectors 200 comprise a plastic container 210 adapted to receive, in its interior, urine from an animal, and a metallic upper grid 220, for example, made of aluminum or stainless steel, on which the animal can be arranged to receiving your feces. The upper grid 220 of the non-limiting example shown is configured as a mesh 12 cm long and 10 cm wide with a separation of 4 mm to act as a separating element for faeces and urine from the animal, that is, to retain faeces and , at the same time, allowing the urine to fall into the container 210. In this way, the animal's feces and urine samples can be collected separately avoiding possible cross-contamination of the samples.

A 0.75 mm wide plastic protective frame 230 surrounds it peripherally on top of the metallic upper grid 220 to prevent direct contact of the animal or the professional with the upper grid 220 of the individual collector 200 and thus avoid damage. In the example shown, the protective frame 230 has coupling elements such as hooks for snap engagement of the protective protective frame 230 to the container 210 of the individual sample collector 200 with the upper rack 220 sandwiched between the protective frame 230 and container 210 of individual sampler 200. In the non-limiting example shown, protective frame 230 is attached to individual manifold 200 via four 3 x 3 mm hooks located 2 by 2 on each side of the container 210 of each individual collector 200. Other dimensions are possible.

By professional is understood here a user, researcher or caregiver who can perform operations of taking samples of feces and urine from animals through the multi-collector device 100 that is described, for care and research in order to monitor and record the status of animals and evaluate results of experimental procedures.

As noted above, interior space 120 of base body 110 is compartmentalized to house six individual sample collectors 200 for simultaneous collection of urine and feces from multiple animals. In the non-limiting example shown in the figures, the compartments defined in the interior space 120 of the base body 110 have a length of 15-20 cm and a width of 10-15 cm. Other dimensions are possible depending on the type of animal to be sampled.

One of the compartments could be designed to house a container for storing objects such as gauze, 10 cm long and 10 cm wide for example. To define said compartments of the interior 120 of the base body 110 of the multi-collector 100, in the example shown, a longitudinal dividing wall 260 and two transverse dividing walls 260 are arranged in the interior space 120 of the base body 110. Said dividing walls Longitudinal and transverse sections 260 divide the interior 120 of the base body 110 of the multi-collector 100 into the aforementioned six compartments intended to house corresponding individual collectors 200.

The dividing walls 260 are removably inserted into guide elements 240. These are U-shaped guide elements 240 that are attached, coupled or integral with interior surfaces of the interior walls 120 of the base body 110. Thanks to the guide elements 240, the dividing walls 260 can be mounted and dismounted by sliding quickly and easily from the base body 110 thus facilitating and speeding up cleaning, maintenance and repair operations of the multi-collector 100.

With the described configuration, six individual manifolds 200 can be arranged in the compartments defined by the dividing walls 260 inside 120 of the base body. 110. Each of the individual manifolds 200 is engaged in the bottom of the base body 110 releasably snapped between abutment elements 150 disposed at opposite corners of the bottom of each compartment of the base body 110. The abutment elements 150 are defined by two walls arranged at right angles which, in use, come into contact with corresponding lower opposite corners of the containers 210 of the individual manifolds 200. The spacing of the opposing stop elements 150 at the bottom of each compartment of the body Base 110 is suitable for each individual manifold 200 to be temporarily tightly held in position. Thus, once an individual manifold 200 has been inserted into the interior 120 of the base body 110, it cannot be removed if it is not pulled by applying a certain force. This allows the sampling to be carried out very efficiently and safely, without the possibility of movement of the individual collector 200 during said operations. Once the samples are obtained, each individual manifold 200 can be removed from the interior 120 of the base body 110 by suitably pulling the same.

As shown in Figure 1 of the drawings, base body 110 includes a ventilated top cover or lid 130 configured to prevent animals from escaping while within multi-collector 100. In the non-limiting example shown in said figure 1, the cover 130 includes a suitable metallic mesh to allow ventilation of the interior 120 of the multicolector 100. The metallic mesh allows to guarantee adequate conditions in the multicolector 100 while samples are taken from the animals. The vented top cap 130 of the non-limiting example shown is 45 cm long and 29 cm wide, although other measurements are possible. In the example being described, the vented top cap 130 is separate from the base body 110 and is configured to slideably engage the top thereof.

Base body 110 includes handles 250 formed on opposite side walls thereof which project outwardly thereof for convenient handling of multi-collector 100.

In the illustrated example, the multi-collector 100 also includes an external housing 140 for accommodating cards. Said external housing or card holder 140 is located on an external wall of the base body 110 and may include at least one transparent area to be able to see the cards contained therein. In the example shown, the card holder 140 measures 4.50 cm high, 12 cm long and 0.50 cm wide, although other dimensions are possible.

Also in the example shown, liquid detection means 160 are included to detect the presence of urine in each container 210 of the individual sample collectors 200. Said liquid detection means 160, in the particular example shown, comprises a sensor of Mounted within 120 of the base body 110 of the multi-collector 100, below each container 210 of the individual sample collectors 200. The liquid sensors 160 activate a warning light disposed below the outer housing 140 to indicate that there is A urine sample is available in the individual collector 200 informing the professional, therefore, that the sample collection has been completed. When the practitioner has collected the sample from the individual collector 200 in question, the warning light turns off.

In the non-limiting example that is described, the liquid sensors 160 work with one or more rechargeable batteries housed in a double bottom, not shown, of the base body 110 where the wiring of the liquid detection means 160 is also housed.

Although only one particular example of the present laboratory device for collecting animal samples has been described herein, the skilled person will understand that many other alternative examples and / or uses are possible, as well as obvious modifications and equivalent elements. Thus, for example, the aspects described for the individual sample collectors of the present laboratory device can be applied, as appropriate, to all the individual sample collectors mounted within the laboratory device, or to a single sample collector, or some of them.

The reference signs relating to the drawings that appear in parentheses in a claim are only to attempt to increase the understanding of the claim, and should not be construed as limiting the scope of protection of the claim. The scope of the present description should not be limited to the specific example described, but should be determined solely by a proper reading of the appended claims.
