Description

Technical Field

[0001] The invention relates to the technical field of gastric drenchers, in particular to a high-position medicine gastric drencher for sows with postpartum diarrhea. Background Art

[0002] Postpartum diarrhea in sows is a common and devastating condition in large-scale pig farming. It not only weakens the sow's body and weakens its immune system, impacting subsequent estrus, breeding, and the growth and development of suckling piglets, but also causes significant economic losses to the farming company. Timely and effective drug treatment is crucial to controlling the condition and ensuring sow health, and oral administration is a common, direct, and effective treatment.

[0003] Traditional gavage devices have many problems when performing gavage on weak sows after parturition. Because sows are extremely weak after parturition and are extremely sensitive to external stimuli, they are prone to stress reactions such as struggling during gavage. This not only increases the difficulty of operation, but also greatly increases the risk of esophageal damage. Once the esophagus is damaged, it may cause a series of complications such as infection, further endangering the health of the sow. In addition, some existing gavage devices attempt to relieve sow stress by applying inducers to the outside of the gavage tube, but the existing design has significant defects. The inducer is evenly applied. During the gavage process, the amount of inducer released remains unchanged, whether in the initial insertion stage or in the deep esophagus stage. The release of the inducer is difficult to achieve gradient release according to the gavage depth, and the sow cannot be given the appropriate induction intensity at different stages, and the sow's struggling intensity at each stage of gavage intubation cannot be effectively reduced. Based on this, a high-position drug gavage device for sows with postpartum diarrhea is proposed. Summary of the Invention

[0004] In order to overcome the problems existing in the related art, the present invention provides a high-position drug gavage device for sows with postpartum diarrhea, which can increase the amount of inducer released in a gradient manner as the insertion depth increases during the gavage process.

[0005] To achieve the above object, the present invention provides a high-position drug gavage device for treating postpartum diarrhea in sows, comprising a gavage tube body, one end of which is provided with a liquid outlet head, and the other end of which is detachably provided with a syringe, and further comprising:

[0006] The base body, wherein the gavage tube body passes through the base body and forms a sliding fit structure with the base body;

[0007] The inducer release component is arranged on the gavage tube body and is close to one end of the liquid outlet head. The inducer release component is used to synchronously release the inducer when the gavage tube body penetrates into the sow's throat, and as the insertion depth of the gavage tube body increases, the release amount of the inducer increases gradually.

[0008] Preferably, the inducer release component includes an inflatable part and a follower extrusion part. The inflatable part includes a plurality of first sleeves spaced apart along the axial direction of the gavage tube body and fixedly connected to the gavage tube body. An independent first inducer storage tank is provided inside each first sleeve. The outer wall of the first sleeve is provided with discharge micropores that can allow the inducer to pass through under pressure, and the aperture size of the discharge micropores gradually increases from one end close to the liquid outlet head to the other end. During the insertion process of the gavage tube body, the follower extrusion part follows and applies extrusion force to the inflatable part, causing the inducer in the first inducer storage tank to be squeezed out through the discharge micropores.

[0009] Preferably, an inner plate and an intermediate soft interlayer are provided inside the first sleeve, an air supply groove is provided between the inner plate and the intermediate soft interlayer, and the first inducer storage groove is located in the annular space between the intermediate soft interlayer and the inner wall of the first sleeve.

[0010] Preferably, the inflatable member further comprises:

[0011] An air delivery tube is arranged in the gavage tube body;

[0012] The air bag is arranged on the seat body, one end of the air supply pipe is connected to the air bag, and the other end of the air supply pipe extends into the air supply groove.

[0013] Preferably, the follower extrusion member includes:

[0014] A collar, detachably mounted on the outside of the gavage tube;

[0015] a connecting block, fixed on the collar;

[0016] A central pressing block connected to the lower side of the connecting block via a connecting rod;

[0017] The spring is connected between the seat body and the connecting block and is located outside the airbag.

[0019] Preferably, the inducer release component includes a temperature release component, and the temperature release component includes:

[0020] A hollow frustum is provided on the outside of the gavage tube, wherein the outer wall of the hollow frustum is provided with a dispensing hole and the outer wall of the hollow frustum is coated with a thermally responsive gel coating, wherein the thickness of the thermally responsive gel coating gradually increases from one end of the hollow frustum close to the liquid outlet head to the other end;

[0021] A plurality of second inducer storage tanks are arranged inside the hollow frustum along the length direction of the hollow frustum through partitions.

[0022] Preferably, the inducer release component includes a switchable release component, which includes at least two second sleeves, which are arranged on the outside of the gavage tube body at intervals, and the outer wall of the second sleeve is provided with micropores, and each second sleeve has an independent opening and closing channel.

[0023] Preferably, the switchable release member further includes:

[0024] a main agent delivery pipe, the main agent delivery pipe being connected to a branch agent delivery pipe, the branch agent delivery pipe being equipped with a micro-electrically controlled valve, an inducer inlet cavity being provided inside the second sleeve, and a liquid outlet end of the branch agent delivery pipe extending into the inducer inlet cavity;

[0025] A micro pump is installed at the liquid inlet end of the drug delivery main pipe.

[0027] The technical solution provided by the present invention can have the following beneficial effects:

[0028] 1. In the present invention, the inducer is released in a gradient manner. As the insertion depth increases during the gavage process, the amount of inducer released increases in a gradient manner. A small amount of inducer is released at the initial stage of gavage to avoid over-stimulation of the sow. As the insertion deepens, more inducer is gradually released to offset the sow's discomfort and reduce the intensity of its struggle, thereby creating stable and safe conditions for the gavage operation. At the same time, it is also conducive to the smooth downward movement of the pipeline and prevents the sow from having a violent reaction in sensitive areas.

[0029] 2. In the present invention, the modular design of the inflatable part makes the operation of replenishing the inducer simple and convenient, and can be reused many times, thereby reducing the cost of use and reducing the generation of medical waste.

[0030] 3. In the present invention, different inducer release components have their own characteristics. For example, the inflatable part is released through mechanical extrusion, the temperature release part uses the heat-responsive gel coating for self-response release, and the switchable release part can achieve precise positioning release and programmable dosage control, which meets different scenarios and needs and enhances the practicality of the gavage device.

[0031] 4. In the present invention, the detachable clamping parts and supporting parts on the base body cooperate to form a three-dimensional stable structure. The clamping parts can adapt to pig house railings of different specifications. The supporting parts can be raised and lowered with the bottom end touching the ground, effectively dispersing the lateral force and vertical pressure generated during the operation of the gavage dispenser, ensuring that the gavage dispenser maintains a horizontal and stable state, significantly improving operational safety and accuracy.

[0032] 5. In the present invention, the vibration module added to the follower extrusion member ring can generate vibrations of different frequencies and intensities, which has a massage effect to relieve the sow's discomfort, promote esophageal peristalsis, help the gavage tube to be inserted smoothly, and also help the diffusion of inducers and drugs to improve the absorption effect.

In the description of the present invention, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0053] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0054] Example 1:

[0055] See Figure 1-Figure 5As shown, the present invention proposes a high-position drug gavage device for sows with postpartum diarrhea, including a gavage tube body 1. The gavage tube body 1 is made of medical-grade silicone material, has good flexibility and biocompatibility, and can reduce irritation to the sow's throat and esophagus. A liquid outlet head 2 is installed at one end of the gavage tube body 1. The liquid outlet head 2 is conical in design, which is convenient for smooth insertion into the sow's mouth and esophagus. A miniature camera can be embedded at the end of the liquid outlet head 2. The camera adopts a high-definition miniature wide-angle lens with a resolution of up to 1080P, which can clearly capture the situation inside the esophagus. The miniature camera is connected to the display screen of the external device via wireless or data cable. During the gavage process, the operator can observe the internal picture of the esophagus in real time and accurately control the insertion direction and depth of the gavage tube body 1, thereby ensuring Accurately insert into the esophagus, effectively avoid inserting into the trachea, reduce operational risks, and ensure the safety of the sow. The other end of the gavage tube body 1 is detachably provided with a syringe 3. The syringe 3 adopts the standard medical syringe specifications and is marked with scales, which is convenient for accurately measuring the dose of the diarrhea medicine contained. The syringe 3 and the gavage tube body 1 are connected by a threaded connection, which not only ensures the tightness of the connection and prevents drug leakage, but also facilitates disassembly and installation, and is convenient for replacing the syringe 3 and cleaning the gavage tube body 1. When in use, the operator inhales the prepared diarrhea medicine into the syringe 3, and by pushing the push rod of the syringe 3, the medicine can be injected into the gavage tube body 1 and then delivered to the sow's stomach. In addition, it also includes an inducer release component 4 and a seat body 5. The seat body 5 is the gavage tube body 1 It provides support and guidance, and is internally provided with a sliding through hole adapted to the gavage tube body 1. The gavage tube body 1 passes through the seat body 5 and forms a sliding fit structure with the seat body 5. The inducer release component 4 is provided on the gavage tube body 1 and is close to one end of the liquid outlet head 2. The inducer release component 4 is used to synchronously release the inducer (which can be fructose water or others) when the gavage tube body 1 penetrates into the sow's throat. As the insertion depth of the gavage tube body 1 increases, the amount of inducer released increases gradually. The amount of inducer released will increase gradually with the increase in the insertion depth of the gavage tube body 1. A small amount of inducer is released in the early stage of gavage to avoid excessive stimulation to the sow. As the insertion depth deepens, more inducer is gradually released to ensure that the sow can swallow the medicine smoothly, thereby improving the success rate and effect of gavage.

[0056] In addition, flexible bristles (not shown) can be provided on the outer wall of the liquid outlet head 2. The bristles are made of soft medical-grade nylon. During the process of inserting the bristles into the sow's mouth and esophagus, the flexible bristles can gently clean the inner wall of the esophagus and remove possible mucus, food residues, etc., to prevent these substances from affecting the absorption of the drug, while reducing bacterial growth and reducing the risk of esophageal infection in the sow.

[0057] Additionally, physiological parameter sensors (not shown) can be integrated into the gavage tube 1 near the outlet 2. These sensors include a temperature sensor, a pH sensor, and a pressure sensor. The temperature sensor monitors temperature changes in the sow's esophagus and stomach in real time, the pH sensor detects gastric pH, and the pressure sensor monitors esophageal and gastric pressure. These physiological parameter data are transmitted via a wireless transmission module to an external smart terminal device, such as a tablet or mobile phone. This allows operators to understand the sow's physiological state in real time and adjust the dosage and type of gavage medication based on this data, achieving personalized treatment. This data also provides data support for subsequent disease diagnosis and treatment.

[0058] See Figure 2-Figure 5 As shown, the inducer release component 4 includes an inflatable part 41 and a follower extrusion part 42. The inflatable part 41 adopts a modular design and includes a plurality of first sleeves 412 distributed at equal intervals along the axial direction of the gavage tube body 1. Each sleeve is firmly adhered to the outer wall of the gavage tube body 1 through a medical-grade adhesive to form an integrated structure. Each first sleeve 412 is an independent sealed unit, and an annular chamber is provided inside as a first inducer storage tank 4123 for storing the inducer. The chamber can be made of highly elastic medical silicone material with good chemical stability and biocompatibility.

[0059] A three-layer composite structure is adopted inside the first sleeve 412: the inner layer is a hard inner plate 4121, which provides structural support; the middle layer is an elastic middle soft interlayer 4122, which is made of polyurethane elastomer material and has excellent deformation recovery ability; the outer layer is the first sleeve 412 body, and a closed air supply groove 4124 is formed between the inner plate 4121 and the middle soft interlayer 4122, which is connected to an external inflation device and can control the deformation of the middle soft interlayer 4122 by gas pressure. The first inducer storage groove 4123 is located in the annular space between the middle soft interlayer 4122 and the inner wall of the first sleeve 412. When the middle soft interlayer 4122 is compressed and deformed, it can effectively squeeze the agent in the first inducer storage groove 4123.

[0060] The outer wall surface of each first sleeve 412 is evenly distributed with discharge micropores. The number and size of the discharge micropores on each first sleeve 412 are different. The aperture size of the discharge micropores gradually increases from one end close to the liquid discharge head 2 to the other end. The micropores can be processed by laser etching technology. The hole wall is smooth and burr-free to ensure the smooth release of the drug. The micropore size design follows a special gradient law: from the proximal end close to the liquid discharge head 2 to the distal end away from the liquid discharge head 2, the aperture size of the discharge micropores gradually increases from 0.1mm to 0.3mm ( For example, three first sleeves 412 are provided, with the diameters of 0.1 mm, 0.2 mm, and 0.3 mm from one end close to the liquid outlet head 2 to the other end, respectively. This design allows the release of the inducer at the proximal end to be smaller, thereby avoiding excessive drug concentration irritating the stomach; the release at the distal end to be larger, thereby ensuring effective distribution of the drug in the intestine. Secondly, the deeper the gavage tube goes into the throat / esophagus, the stronger the sow's discomfort (foreign body sensation, pressure sensation) is usually. The gradient-enhanced inducer can provide stronger positive stimulation, offset the discomfort, and reduce the intensity of the struggle.

[0061] During the insertion of the gavage tube body 1 , the follower extrusion member 42 follows and applies an extrusion force to the inflatable member 41 , thereby causing the inducer in the first inducer storage tank 4123 to be extruded through the discharge micropores.

[0062] See Figure 2-Figure 5 As shown, the inflatable member 41 also includes an air supply tube 411 and an air bag 413. The air supply tube 411 is arranged in the gavage tube body 1, and the air bag 413 is arranged on the seat body 5. One end of the air supply tube 411 is connected to the air bag 413, and the other end of the air supply tube 411 extends into the air supply groove 4124.

[0063] The follower extrusion member 42 includes:

[0064] The collar 421 is detachably mounted on the outside of the gavage tube 1. The gavage tube 1 is composed of a soft tube portion and a hard tube portion. The hard tube portion is located on one end where the syringe 3 is mounted. The collar 421 is located on the outside of the hard tube portion.

[0065] Connecting block 422, fixed on collar 421;

[0066] The central pressing block 424 is connected to the lower side of the connecting block 422 via a connecting rod, and the air supply pipe 411 passes through the central pressing block 424;

[0067] The spring 423 is connected between the seat body 5 and the connecting block 422 and is located outside the airbag 413 .

[0068] In addition, a side pressure block 425 is fixed to the side wall of the central pressure block 424 , and an extrusion slope 426 is provided on the side pressure block 425 .

[0069] Through the above, in actual use, as the staff gradually inserts the liquid outlet head 2 ends of the gavage tube body 1, the hard tube part drives the ring 421 to move gradually downward. Initially, the side pressure block 425 with an extrusion slope 426 squeezes the end of the air bag 413 to squeeze a small amount of air through the air supply pipe 411 into the air supply groove 4124. The gas squeezes the middle soft interlayer 4122, and the middle soft interlayer 4122 deforms and squeezes the inducer in the first inducer storage groove 4123, so that the inducer is sent out from the discharge micropores to attract the sow to open its mouth for soothing. As the insertion depth of the gavage tube body 1 continues to increase, the contact area and extrusion force of the central pressure block 424 and the side pressure block 425 with the air bag 413 gradually increase, and the increase in pressure causes the degree of compression of the air bag 413 to continue to increase. , more air is sent into the air delivery groove 4124, which in turn applies a stronger squeezing pressure to the middle soft interlayer 4122, prompting more inducers in the first inducer storage groove 4123 to be released through the discharge micropores. This inducer release mode that increases synchronously with the insertion depth is like a soothing program customized for sows. As the discomfort caused by the insertion of the gavage tube body 1 increases, the gradient-enhanced inducer provides stronger positive stimulation, effectively offsets the sow's discomfort reaction, significantly reduces its struggling intensity, and creates stable and safe conditions for subsequent gavage operations. Secondly, the gradient release can maintain attraction, guide the sow to cooperate with the swallowing action, and facilitate the smooth descending of the tube. In addition, when the tube reaches sensitive areas (such as the middle esophagus), the additional inducer can provide immediate soothing to prevent sudden head shaking or retreat.

[0070] Secondly, after gavage use, the downward-moving central pressure block 424 can be restored to its original state through the elastic action of the spring 423. When the inducer in the first inducer storage tank 4123 is exhausted due to multiple uses and is insufficient to support the next gavage demand, the staff can replenish the gavage device by simply taking out the syringe with the injection needle and inserting the needle into the sealed injection port reserved in the first inducer storage tank 4123 to inject the inducer. Through this convenient replenishment method, the gavage device gets rid of the limitation of single use and realizes multiple reuse, which not only reduces the cost of use, but also reduces the generation of medical waste, and is both economical and environmentally friendly.

[0071] In addition, a vibration module (not shown) can be added to the ring 421 of the follower extrusion member 42. The vibration module consists of a micro motor and an eccentric wheel, and is powered by a wire inside the gavage tube body 1. The outside of the wire is waterproof and insulated. When the follower extrusion member 42 is inserted and moved downward with the gavage tube body 1, the vibration module can be started according to a preset program to generate vibrations of different frequencies and intensities. The vibrations can be transmitted to the gavage tube body 1 and the sow's esophageal wall. On the one hand, it has a massage effect, alleviating the sow's discomfort caused by the insertion of the gavage tube body. On the other hand, it can promote esophageal peristalsis, helping the gavage tube body to be inserted more smoothly. At the same time, it also helps the diffusion of inducers and drugs in the esophagus and stomach, thereby improving the absorption effect.

[0072] Example 2:

[0073] See Figure 7 、 Figure 8 and Figure 10 As shown, the difference between this embodiment and the first embodiment is that the inducer release component 4 includes a temperature release member 43, the temperature release member 43 includes a hollow frustum 431 and a plurality of second inducer storage tanks 432, the hollow frustum 431 is arranged on the outside of the gavage tube body 1, the outer wall of the hollow frustum 431 is provided with a discharge hole, and the outer wall of the hollow frustum 431 is coated with a thermal response gel coating 433 (such as gelatin-oxidized dextran or other gel coatings that meet biocompatibility, non-toxicity and precise temperature control release), the thickness of the thermal response gel coating 433 increases from the hollow frustum 431 near the discharge hole. The head 2 gradually expands from one end to the other end, and multiple second inducer storage grooves 432 are arranged inside the hollow conical body 431 through partitions along the length direction of the hollow conical body 431. Before insertion, the tube body is at room temperature (<30°C), the gel is stable, and the inducer is not released. After insertion into the mouth, the tube body is heated by body temperature (≈39°C), and the thin coating at the front end dissolves first to release a small amount of inducer. When inserted deeper, the thick coating in the middle section is accelerated to dissolve due to continuous heat and mechanical friction, releasing a larger dose of inducer, thereby realizing the release of gradient inducer. No additional pumps and sensors are required, self-responsive release, and the structure is simple.

[0074] It should be noted that, for this design, the hose portion and the hard tube portion of the gavage tube body 1 are detachably connected, and the liquid outlet head 2 on which the micro camera is installed and the hose portion are also detachably connected. Each time the tube is used, the thermally responsive gel coating 433 dissolves and cannot be used a second time. In this case, the hose portion can be designed as a disposable item.

[0075] In addition, in order to further reduce the waste of resources, a section of the hose portion where the temperature release member 43 is installed can be set as a disposable item, and this section can be replaced after use.

[0076] Example 3:

[0077] See Figure 9 and Figure 11 As shown, the difference between this embodiment and embodiment 1 is that the inducer release component 4 includes a switchable release member 44, and the switchable release member 44 includes at least two second sleeves 442. The second sleeves 442 are made of medical-grade silicone material. The second sleeves 442 are arranged on the outside of the gavage tube body 1 at intervals. The outer wall of the second sleeve 442 is provided with micropores, and each second sleeve 442 has an independent opening and closing channel.

[0078] The switchable release member 44 also includes a drug delivery main pipe 441 and a micro pump 443. The drug delivery main pipe 441 is connected to a drug delivery branch pipe 445. The drug delivery main pipe 441 and the drug delivery branch pipe 445 are made of medical-grade materials with good flexibility and anti-kink performance. A micro-electrically controlled valve 446 is installed on the drug delivery branch pipe 445. The micro-electrically controlled valve 446 is preferably an electrically controlled valve equipped with a battery and a waterproof structure. The second sleeve 442 is provided with an inducer inlet chamber 444. The liquid outlet end of the drug delivery branch pipe 445 extends to the inducer inlet chamber 444. Inside 44, the micro pump 443 is installed at the liquid inlet end of the drug delivery main pipe 441. During the oral insertion stage, the micro pump 443 is started and only a small amount of inducer is released from the front micropore to attract the mouth to open and initially soothe. During the throat passage stage, when the pipe enters deep into the throat, the micro pump 443 increases the flow rate and opens the middle micropore to form a high-concentration inducer "cloud", which strongly stimulates the swallowing reflex. After entering the esophagus, the inducer release is greatly reduced or stopped (to avoid waste and choking risks), which can achieve more precise positioning release and programmable dosage control.

[0079] Example 4:

[0080] See Figure 6 As shown, the difference between this embodiment and the first embodiment is that a clamping member 7 is detachably provided on the base body 5, and a support member 6 is also detachably provided on the base body 5. The clamping member 7 can adopt a two-way clamping arm structure, and the inner sides of the clamping arms on both sides are covered with a non-slip silicone layer with a high friction coefficient. The clamping range can be adjusted by a rotary adjustment bolt, and can be adapted to pig house rails of different specifications. The support member 6 adopts a liftable structural design, and its bottom end can contact the ground of the pig house. The two cooperate to form a three-dimensional stable structure, which effectively disperses the lateral force and vertical pressure generated during the operation of the gavage dispenser, can ensure that the gavage dispenser maintains a horizontal and stable state, and significantly improves the operational safety and accuracy.
