Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, and in particular to a vest for collecting non-invasive cardiovascular data of experimental animals. Background Art

[0002] In basic safety pharmacology research and related preclinical drug studies, noninvasive cardiovascular data collection is often required using experimental animals, such as pigs. This process requires a vest equipped with data collection equipment to be worn on the animal's torso to collect and transmit cardiovascular data. Therefore, the relevant experimental equipment must be able to properly accommodate these devices.

[0003] However, existing vests are often designed to fit the body type, personality, and behavioral habits of experimental animals. Animals often struggle violently while wearing these vests, causing them to fall off and potentially injuring the animals. These issues not only affect the fit of the data collection equipment to the animals' bodies but also restrict their freedom of movement, making them incapable of effectively collecting noninvasive cardiovascular data from them. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the utility model provides a non-invasive cardiovascular data collection vest for experimental animals, comprising a vest body, wherein the vest body is provided with an electrocardiogram electrode patch and a signal transmitting device for collecting the cardiovascular data of the experimental animal, and the electrocardiogram electrode patch is connected to the signal transmitting device through a data transmission line, wherein the vest body is provided with multiple sets of wearing zippers to accommodate the experimental animals of different body sizes; a first Velcro and two blood sample collection holes are provided on the neck side of the vest body, and a second Velcro is provided on the abdominal side; at least one hole is provided between the neck side and the abdominal side of the vest body for the limb movement of the experimental animal, and the hole is closer to the neck side than to the abdominal side.

[0005] In the non-invasive cardiovascular data acquisition vest as described above, optionally, a device fixing bag and at least one data line hole are provided on the back side of the vest body.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0028] like Figures 1 to 4 As shown, the non-invasive cardiovascular data collection vest for experimental animals of the present invention comprises a vest body 1. The vest body 1 is provided with multiple sets of wearing zippers 2 to accommodate experimental animals of different sizes (such as experimental pigs).

[0029] The vest body 1 is equipped with an ECG electrode patch, a data line, and a signal transmitting device for collecting cardiovascular data of experimental animals. It should be noted here that the ECG electrode patch is used to be directly attached to the skin of the experimental animal, and the cardiovascular data is collected by detecting the physiological signals (including the rhythm and intensity of the heartbeat, etc.) generated by the animal's heart. The electrode patch converts these signals into measurable voltage signals and transmits them to the signal transmitting device via the data line. The signal transmitting device can transmit these collected non-invasive cardiovascular data to the laboratory computer workstation for analysis through wireless communication technologies such as Bluetooth technology. The signal processing and transmission technology between the ECG electrode patch and the signal transmitting device has been maturely applied in the medical and scientific research fields, belongs to the prior art, and is not the focus of the present invention. The ECG electrode patch, data line, and signal transmitting device are not reflected in the drawings of the specification, so they will not be described in detail here.

[0030] Optionally, the back side 13 of the vest body 1 is provided with a device securing pocket 5 and at least one data cable hole 6 to further optimize the routing and arrangement of data cables and the storage of signal transmission equipment. This prevents equipment from falling off or shifting during experimental data collection, further increasing the stability and reliability of experimental data collection. The device securing pocket 5 can be sewn onto the vest body 1. The specific location of the data cable hole 6 can be designed to correspond to the actual wiring needs of the operator.

[0031] The inner lining of the device fixing bag 5 can also be provided with a waterproof cloth to prevent the signal sending device from being affected by animal sweat or external water sources. Figure 1 、 Figure 3 and Figure 4 As shown, the device securing bag 5 can be provided with a zipper 51 and a third Velcro 52 located outside the zipper 51, and a metal buckle 53 is provided at the closing portion of the zipper 51. The device securing bag 5 is sealed by the zipper 51 with a hardened tooth closure. The third Velcro 52 is designed to prevent the signal transmitting device from falling. The metal buckle 53 at the closing portion of the zipper 51 can be connected to the zipper to further prevent the device from falling.

[0032] In this embodiment, Figure 1 and Figure 2 As shown, the wearing zipper 2 of the vest body 1 opens and closes on the back side 13. In an optional embodiment, the right back side 13 of the vest body 1 can be provided with two sets of wearing zippers 2 with hard teeth openings. Specifically, the operator can select a combination of wearing zippers 2 in appropriate positions according to the body size of the experimental animal to adjust the size of the vest body 1. For example, the wearing zipper 2 combination closer to the center line of the vest body 1, that is, more inward, can provide a smaller vest size, and the wearing zipper 2 combination farther away from the center line of the vest body 1, that is, more outward, can provide a larger vest size. In actual use, the operator can also use a combination of one outer and one inner wearing zipper 2 to form a vest of moderate size.

[0033] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the abdominal side 12 of the vest body 1 is designed with an arc that is retracted inward toward the neck side 11 to prevent the vest from hindering the normal urination of the experimental animal.

[0034] In this embodiment, the neck side 11, the abdomen side 12, and the edges of the holes 3 of the vest body 1 are all wrapped with flannel to reduce friction between the vest and the experimental animal's skin. The vest body 1 can be made of polyester-cotton mesh fabric, making the vest more breathable and comfortable for the experimental animal.

[0035] like Figure 1 、 Figure 2 and Figure 4 As shown, at least one hole 3 is provided between the neck side 11 and the belly side 12 of the vest body 1 for limb movement of the experimental animal. Figure 1 and Figure 2 The figure shows a situation where two elliptical holes 3 are provided. Figure 4 The illustrated embodiment shows a case where an elliptical hole 3 is provided. The elliptical hole 3 can better conform to the body curve of the experimental animal, thereby increasing the comfort level of the animal in wearing the vest. The hole 3 is closer to the neck side 11 than to the abdominal side 12 to ensure that the forelimbs of the experimental animal can move more freely and normally, thereby avoiding the restriction of the activities of the experimental animal after wearing the vest, thereby affecting the experimental animal's mood (struggling and being easily injured), comfort (restricted forelimb activities will cause discomfort), and the accuracy of the experimental data collected. Therefore, the non-invasive cardiovascular data collection vest for experimental animals provided by the present invention can better collect cardiovascular data from experimental animals. In addition, in this embodiment, the edges of the hole 3 are wrapped with velvet to reduce friction on the bottom of the forelimbs of the experimental animal.

[0036] Furthermore, if Figure 1 and Figure 4 As shown, the neck side 11 of the vest body 1 is provided with a first Velcro 111, and the abdominal side 12 is provided with a second Velcro 121. The design of these two Velcros can not only fix the vest when worn, but also adjust the neck size and abdominal size of the vest body 1 when worn on the experimental animal in detail, further preventing the vest from falling off during experimental data collection.

[0037] In addition, blood sample collection can be used to detect physiological indicators of experimental animals, such as blood sugar, growth hormone or prolactin, etc. These indicators are crucial for evaluating the cardiovascular health of animals. In the present invention, blood sample collection is also an important means of obtaining experimental data. By analyzing blood samples, experimenters can study the cardiovascular function of animals, the mechanism of action of drugs, etc. In order to facilitate the collection of data, (venous) blood samples are collected from the lower neck of the experimental animals, such as Figure 1 and Figure 2 As shown, in this embodiment, two blood sample collection holes 7 are provided on the neck side 11 of the vest body 1. In an alternative embodiment, these two blood sample collection holes 7 are oval in shape and smaller than the aforementioned holes 3, providing sufficient space for blood sample collection. To further reduce friction on the experimental animal's neck, the edges of the two blood sample collection holes 7 are wrapped with flannel.

[0038] Specifically, in an optional embodiment, the first Velcro 111 and the second Velcro 121 each include a bristle noodle tape and a round noodle tape, either of which is completely sewn to the vest body 1, and the other is used to be freely adjusted to a suitable position and connected to a strip completely sewn to the vest body 1. Figure 1 and Figure 4 In the illustrated embodiment, the first Velcro 111 is specifically designed as follows: a quilled noodle tape (a polyester tape with a quilled surface for Velcro) is provided on the right side of the neck side 11, and a round noodle tape (a polyester tape with a round surface for Velcro) is provided on the left side and sewn to the vest body 1. While securing the vest body 1, the enclosing size of the neck side 11 of the vest body 1 can be adjusted by adjusting the length of the connection between the round noodle tape and the quilled noodle tape. Similarly, the second Velcro 121 is specifically designed as follows: a quilled noodle tape (a polyester tape with a quilled surface for Velcro) is provided on the right side of the abdomen side 12, and a round noodle tape (a polyester tape with a round surface for Velcro) is provided on the left side and sewn to the vest body 1. While securing the vest body 1, the enclosing size of the abdomen side 12 of the vest body 1 can be adjusted by adjusting the length of the connection between the round noodle tape and the quilled noodle tape.

[0039] Furthermore, in this embodiment, the neck side 11 and / or the abdomen side 12 of the vest body 1 may be further provided with elastic side bands 14 with elasticity and stretchability. Figure 1 and Figure 4 The figure shows only the case where the neck side 11 is provided with an elastic side band 14. The design of the elastic side band 14 can better fit the neck and / or abdomen of the experimental animal to prevent the vest body 1 from falling off, making the collected experimental data more accurate and stable.

[0040] In an optional embodiment, if Figure 4 As shown, the abdominal side 12 of the vest body 1 can also be provided with at least one length-adjustable adjustment strap 4 ( Figure 4 (The figure shows a case with two adjustment straps 4) to prevent the vest body 1 from becoming loose between the neck side 11 and the abdomen side 12. This design can further comprehensively fit the body of the experimental animal, increasing the accuracy of the experimental data collected. In this embodiment, the adjustment straps 4 are buckle webbing.

[0041] The above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by a person skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology shall be within the scope of protection defined by the claims.
