Description

Technical Field

[0001] The invention relates to the technical field of calf infusion, and more particularly to an electrolyte infusion device for treating calf diarrhea. Background Art

[0002] When calves have severe diarrhea, they often become dehydrated and have difficulty standing. Therefore, calves with diarrhea need infusion treatment. During the infusion, the calf needs to be laid down and the four legs tied and fixed. Then, a vein is found in the calf's neck for infusion. During the infusion, the injector needs to hold the needle and syringe with his hand all the time, and hold the calf's head to prevent the needle from falling due to struggle. This method requires the injector to press the calf's head from beginning to end, which requires a lot of physical strength, and it is difficult to ensure that the calf's head does not struggle. At the same time, the injection personnel must be well-trained, find the large vein, find the right angle for the needle, then aim the needle at the vein, and insert it into the vein with force without missing the target. However, because calves have long hair and thick, hard skin, and people must always be on guard against calves that may attack people due to fright, people are generally very cautious and tense when inserting the needle. They perform the operation in panic, and sometimes the struggle of the livestock may cause damage to the syringe and needle, and people may be kicked or bitten by the livestock, which brings a lot of inconvenience to veterinary work.

[0015] Compared with the prior art, the advantages of the present invention are: 1. Compared with the prior art, the injection needle provided in this solution can effectively peel off the tough part of the epidermis layer of the calf's neck, making it easier to insert the needle tube into the blood vessel. The provided expander can effectively maintain the expansion of the expansion part so that the needle tube can be inserted more easily. At the same time, the sharp thorns provided at the front end of the expander can facilitate the insertion and peeling of the tough epidermis, increase the expansion support force of the expander, and can be inserted, expanded, removed and restored through the elastic part.

[0016] Second, this solution uses the elastic force range of the expander to abut the expander under normal conditions. The guide slope at the front end of the expander is set so that when force is applied to it, the force is converted into the expansion force of the expander, and the sharp spikes set on both sides increase the pressure resistance, making the expansion intention of the expander more convenient. When the expander is stretched, the pressure on both sides facilitates the peeling of the epidermis so that the needle tube enters the dermis and blood vessels.

[0017] 3. This solution sets a limit mechanism on the dilator that matches and slides with the needle tube, and changes the dilator from being closed in normal conditions to being expanded in normal conditions. This arrangement reduces the force applied to the dilator when the dilator enters the skin surface, which is more convenient. At the same time, the dilator can be limited and closed by the needle tube when it is not in use. When the dilator and the needle tube tips are aligned and enter the skin surface, the dilator is restored to expand, which is more reasonable and convenient to use.

[0018] 4. This solution provides a booster to facilitate the control of the extrusion and recovery of the expander. When the expander and the needle tube tip enter the skin surface at the same time, a little assistance can be provided to facilitate the entry of the expander. After the expander completes the expansion of the needle tube and enters the blood vessel, the expander can also be pulled back by the booster to reduce the continuous damage of the expander to the expanded wound on the skin surface.

[0019] 5. This solution limits the matching limit mechanism of the dilator and the needle tube. When the dilator tip and the needle tube tip are aligned, the limiter edge on the needle tube can come out of the sliding cavity in the dilator to release the elastic member to rebound and the dilator to expand. In addition, the length of the needle tube limiter is limited to prevent the limiter of the needle tube from being placed in the sliding cavity when the dilator tip and the needle tube tip are aligned, thereby hindering the expansion of the dilator.

[0020] 6. This plan sets up a fixing device to fix the neck of the calf with diarrhea by making it lie on its side, so as to facilitate the infusion of electrolytes in the neck.

[0021] 7. This solution provides a placement table and a wire storage mechanism is provided inside the placement table, which is convenient for stretching and recycling the wire body. The shaving mechanism is connected to it, which is convenient for the shaving mechanism to return to its original position in time after use. It also prevents the shaving mechanism from being accidentally taken away, which is safer.

[0022] 8. This scheme provides a foot fixation part to fix the limbs of the calf. Since the calf with diarrhea cannot stand for a long time, a side-lying foot fixation part is provided to facilitate the fixation of the limbs of the side-lying calf.

[0023] 9. This solution is provided with a shaving mechanism, and a contact plate is provided at the front end of the structure of the shaving mechanism, and a plurality of through holes are provided on the surface of the contact plate, so that the calf hair can pass through the through holes. The shaving blades in the shaving mechanism shave the hair, and finally enter the hair collector, so as to avoid the trouble caused by the inability to collect the calf hair.

[0024] 10. This scheme sets a trigger switch for the shaving mechanism, which is used to start and stop the shaving mechanism, greatly improving the use efficiency and reducing the waste of electricity. The trigger piece is pressed against the shaving part of the calf to start the shaving blades in the shaving mechanism. The upper layer of the trigger piece is a non-conductive material and the lower layer is a metal material, which facilitates the lower layer to connect the circuit system and prevents the upper layer from being accidentally conductive.

The abutting surface 335 is provided with a connecting limiting groove 335-1 that passes through the upper end wall of the expander 331, and the connecting limiting groove 335-1 matches with the inner cavity of the sliding cavity and the limiting groove 331-2, so that the limiting member 333-1 and the limiting block 333-2 enter the sliding cavity along the connecting limiting groove 335-1 at the upper end of the expander 331. The limiting member 333-1 and the limiting block 333-2 are slidably connected with the connecting limiting groove 335-1. Under normal circumstances, the expander 331 is in an expanded state, and the elastic members 334 on both sides of the opening of the expander 331 are in a non-stressed state to maintain the expanded state of the expander 331.

[0044] The upper end of the injection needle 33 is provided with a needle connecting tube 34. Fig.13As shown. The needle connecting tube 34 is connected with an infusion tube 31, and the infusion tube 31 is fixedly connected with the injection needle 33 and communicated with each other. The front end of the needle connecting tube 34 is sleeved with a booster 341, and the booster 341 is slidably connected with the needle connecting tube 34. Boosters 342 are extended on both sides of the booster 341, and the booster 342 is fixedly connected with the booster 341. The front end of the booster 342 is fixedly connected with a fixed shaft 343. The front end of the fixed shaft 343 is extended and obliquely provided with a fixed rod 344, one end of the fixed rod 344 is fixedly connected with the fixed shaft 343, and the other end of the fixed rod 344 is fixedly connected with the upper end side wall of the dilator 331. The inclination angle of the fixed rod 344 matches the front end of the needle connecting tube 34, so that the sliding booster 341 controls the sliding of the dilator 331. The materials used for the booster rod 342, the fixed shaft 343 and the fixed rod 344 connected to the booster member 341 all have a certain toughness. Preferably, the booster rod 342, the fixed shaft 343 and the fixed rod 344 are made in one piece in terms of technology. The elastic force of the elastic member 334 on the booster rod 342, the fixed shaft 343 and the fixed rod 344 is greater than the toughness bearing capacity of the entire rod, so that when the elastic force of the elastic member 334 expands the expander 331, a certain expansion space is provided through toughness. The size of the specific expansion space can be achieved by adjusting the toughness according to actual conditions.

[0045] When the tip of the expander 331 is aligned with the tip of the needle tube 333, the side of the stopper 333-1 away from the tip of the needle tube 333 is flush with the side of the stopper plate 331-1 close to the tip of the expander 331. When the needle tube 333 is aligned with the expander 331 and enters the skin surface, the stopper 333-1 slides out of the sliding cavity, so that the expander 331 expands the skin surface due to the rebound of the elastic member 334. The opening length of the stopper 333-1 and the stopper block 333-2 is less than the opening length of the sliding cavity.

[0046] Working principle: When using this embodiment, first manually put the dilator and the booster on the injection needle and the needle tube. It should be noted during the installation process that the limiter and the limit block at the upper end of the needle tube need to be aligned with the connection limit groove formed at the upper end of the dilator to enter the connection limit groove. The dilator remains in an expanded state when it has not entered the connection limit groove. When the limiter and the limit block enter the connection limit groove and continue to slide downward to enter the sliding cavity formed by the limit plate and the limit groove of the dilator through the connection limit groove, at this time, due to the entry of the limiter and the limit block, the dilator is closed toward the middle and the elastic member is compressed, so that the dilator is in a state of wrapping the needle tube. After the dilator is closed and the tip of the needle tube is aligned with the tip of the dilator, hold the end of the needle connection tube and use the front end of the finger to abut the booster, align with the skin surface and the position of the vein, and insert the needle tube and the tip of the dilator into the skin surface at the same time. Due to the slight assistance of the booster, the tip of the expander enters the surface layer of the skin, and then pushes the needle tube downward to continue sliding. The limiter and the limit block on the needle tube slide out of the sliding cavity, releasing the limit state of the expander and causing the elastic member to rebound, so that the expander can expand the surface layer of the skin. After the expander is expanded, the needle tube can more easily enter the inner layer of the skin and be inserted into the blood vessel. After the needle tube is inserted into the blood vessel, the booster can be pulled to pull the expander outward to reduce the damage to the expansion of the surface layer of the skin.
