Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical detection, and in particular relates to a local skin sealing and fixation device for animal skin patch testing. Background Technology
[0002] The Buehler test is a closed patch test that applies a material or its extract to guinea pigs and observes the skin reaction at the stimulation site for a specified time to evaluate the potential of the test sample to induce a skin sensitization reaction in guinea pigs under test conditions. Directly fixing the test sample to the guinea pig's skin with adhesive tape carries a high risk of it falling off.
[0003] Chinese utility model patent application number 2022220945742 discloses a drug delivery fixation device for the skin on the back of an animal. It achieves rapid fixation of the skin test area through the combination of a first hook and loop fastener on a strap and a binding strip. However, this device has a large contact area with the guinea pig, which can easily cause discomfort and damage to the strap and other structures. Furthermore, the device directly covers the drug delivery area, making direct observation impossible. Utility Model Content
[0004] In view of this, the present invention aims to overcome the defects in the prior art and proposes a local skin closure and fixation device for animal skin patching experiments.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A local skin closure and fixation device for animal skin patching test includes a first fixation member and a second fixation member. The inner sides of the first fixation member and the second fixation member are connected by a first connecting component, and the outer sides of the first fixation member and the second fixation member are connected by a second connecting component.
[0007] The first connecting assembly includes a connecting piece and a telescopic belt. The telescopic belt is connected to the first fixing member and the second fixing member, respectively. The connecting piece is fixed to the telescopic belt, and a pressing plate is provided on the inner side of the connecting piece. The pressing plate presses the adhesive tape downwards to prevent the tape from falling off. The distance between the first fixing member and the second fixing member is less than the width of the tape, which also presses the edge of the tape downwards to prevent the tape from falling off.
[0008] Furthermore, both the first and second fixing members are equipped with connecting shafts, and the end of the telescopic belt has several connecting holes that mate with the connecting shafts. The connecting shafts are adjusted to connect with different connecting holes according to the size of the animal and the location of the test to prevent gaps between the telescopic belt and the animal. The telescopic belt is made of elastic material.
[0009] Furthermore, the second connecting component includes a strap, a plug, and a sleeve. The plug and sleeve cooperate with each other. One end of the strap is connected to the first fixing member and the second fixing member, and the other end is connected to the corresponding plug and sleeve.
[0010] Furthermore, the inner sides of both the first and second fixing members are provided with reinforcing components. The reinforcing components include fixing strips and several inserts. The fixing strips are located on the first and second fixing members, and one end of each insert is fixed to the fixing strip.
[0011] Furthermore, the fixing strip is detachably connected to both the first and second fixing members. It can be installed and removed as needed.
[0012] Furthermore, the first connecting component and the reinforcing component are respectively located on both sides of the first fixing member, and the first connecting component and the reinforcing component are respectively located on both sides of the second fixing member. The insert of the reinforcing component is used to insert into the animal's fur, which facilitates the relative fixation of the fixing device. If no installation is required, it can be directly disassembled.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] The local skin sealing and fixing device for animal skin patching test described in this utility model is provided with a first connecting component, a first fixing component, and a second fixing component, which together reinforce the edge of the patch to prevent it from falling off, and also leave space for observing the state of the patching test; at the same time, a reinforcing component is provided to improve the overall stability of the device and prevent it from falling off.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1-2As shown, a local skin closure and fixation device for animal skin patch testing includes a first fixation member 1 and a second fixation member 2. The inner sides of the first fixation member 1 and the second fixation member 2 are connected by a first connecting assembly, and the outer sides of the first fixation member 1 and the second fixation member 2 are connected by a second connecting assembly. The first connecting assembly includes a connecting piece 3 and a telescopic band 4. The telescopic band 4 is connected to the first fixation member 1 and the second fixation member 2 respectively. The connecting piece 3 is fixed to the telescopic band 4, and a pressing piece 31 is provided on the inner side of the connecting piece 3. The pressing piece presses the adhesive tape down to prevent the tape from falling off. The distance between the first fixation member 1 and the second fixation member 2 is less than the width of the tape, which also presses the edge of the tape down to prevent the tape from falling off.
[0025] Both the first fixing member 1 and the second fixing member 2 are provided with connecting shafts 5, and the end of the telescopic belt 4 is provided with several connecting holes 41, which mate with the connecting shafts 5. The connecting shafts 5 are adjusted to connect with different connecting holes 41 according to the size of the animal and the location of the test to prevent gaps between the telescopic belt 4 and the animal. The telescopic belt 4 is made of elastic material.
[0026] The second connecting component includes a strap 8, a plug 9, and a sleeve 10. The plug 9 and the sleeve 10 cooperate with each other. One end of the strap 8 is connected to the first fixing member 1 and the second fixing member 2, and the other end is connected to the corresponding plug 9 and sleeve 10.
[0027] The inner sides of both the first fixing member 1 and the second fixing member 2 are provided with reinforcing components. Each reinforcing component includes a fixing strip 6 and several inserts 7. The fixing strip 6 is located on the first fixing member 1 and the second fixing member 2, and one end of each insert 7 is fixed to the fixing strip 6. The fixing strip 6 is detachably connected to both the first fixing member 1 and the second fixing member 2. It can be installed and removed as needed.
[0028] The first connecting component and the reinforcing component are located on both sides of the first fixing member 1, and the first connecting component and the reinforcing component are located on both sides of the second fixing member 2. The insert 7 of the reinforcing component is used to insert into the animal's fur, so as to make the position of the fixing device relatively fixed. If no installation is required, it can be directly disassembled.
[0029] Implementation method:
[0030] Before use, select the connecting hole 41 on the telescopic belt 4 according to the size of the animal, and connect the connecting hole 41 to the connecting shaft 5. When using, the operator pulls the first fixing member 1 and the second fixing member 2 outward with both hands to make the telescopic belt 4 extend to a suitable length. Then, insert the plug 7 horizontally into the fur of the animal in the center direction. At this time, the inner sides of the first fixing member 1 and the second fixing member 2 and the pressing plate 31 can press down the edge of the adhesive tape. Finally, wrap the strap 8 around the animal and insert the plug 9 into the plug sleeve 10.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
