Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly relates to a saliva collection device. Background Art
[0002] In the surgical field, for some diagnoses, it is necessary to collect saliva for disease identification. By detecting and analyzing the components of saliva, it helps in diagnosing some diseases, evaluating the physiological functions of the body, and monitoring drug levels. Therefore, a saliva collection device is used in surgical diagnoses; For this reason, the patent with the authorization announcement number CN215306109U discloses a saliva collection device, which relates to the technical field of human saliva collection, aiming to solve the technical problems of the existing saliva collection device being complex in structure and inconvenient to operate. This saliva collection device includes a liquid storage tube, a tube cap, and a liquid collection tube. The liquid storage tube has an accommodation cavity, and the two ends of the liquid storage tube are respectively an open end and a closed end, and the open end communicates with the accommodation cavity; the tube cap is connected to the open end, the liquid collection tube is connected to the closed end, and both between the open end and the tube cap and between the closed end and the liquid collection tube are detachably connected. The utility model can simplify the saliva collection device, simplify the liquid collection procedure, and improve the liquid collection efficiency; When the above-mentioned saliva collection device is in use, saliva collection relies on the patient to passively secrete saliva, and the collection efficiency is relatively low. Moreover, when encountering critically ill unconscious patients, saliva collection is rather difficult, time-consuming, and affects work efficiency. Summary of the Invention
[0003] The purpose of the present invention is to provide a saliva collection device to solve the defect that the existing saliva collection device is inconvenient to promote the patient to secrete saliva.
[0004] To solve the above technical problems, the present invention provides the following technical solution: A saliva collection device includes a housing; One end of the housing is provided with a contact head, both sides inside the housing are fixed with fixing plates, and a vibration structure is arranged at the middle position inside the housing; The vibration structure includes a swinging frame arranged at the middle position inside the housing. An eccentric wheel is arranged inside the swinging frame. One side of the inside of the eccentric wheel penetrates through a driving shaft. One end of the swinging frame is fixed with a connecting rod. Both ends of the connecting rod are fixed with fixing rods. One side of the fixing rods close to the connecting rod penetrates through a connecting shaft. A micro motor is installed on one side of the fixing plate at one end of the driving shaft; A collection structure is fixed on the inner wall of one side of the housing.
[0005] By stimulating the nerve endings on the tongue through the vibration structure, when these nerve endings are stimulated, they will transmit signals to the salivary secretion center in the brain. After receiving the signals, this center will issue instructions to prompt the salivary glands to increase the secretion of saliva. At the same time, this vibration stimulation will also trigger some reflex activities to further promote saliva secretion; the clamping block and the contact head are clamped and fixed through the clamping groove, which facilitates the disassembly and assembly of the contact head, and then a contact head of a suitable size can be selected according to the age of the patient for use; through the collection structure, the saliva inside the patient's oral cavity is discharged in time, avoiding the accumulation of saliva in the patient's oral cavity and causing choking.
[0006] Preferably, one end of the housing close to the contact head is arc-shaped, and the fixing plates are symmetrically distributed on both sides inside the housing.
[0007] Preferably, the collection structure includes a limit seat fixed on the inner wall of one side of the housing. A hose is arranged inside the limit seat. A rotating seat is fixed on the outer wall of the drive shaft on one side of the hose. Squeezing wheels are arranged at both ends of the rotating seat. Fixed blocks are fixed on the inner walls at both ends of the limit seat. Handles penetrate through the fixed blocks. One ends of the handles close to the hose are rotatably connected with movable blocks.
[0008] Preferably, the limit seat is in a "U" shape, and both ends of the hose extend to the outside of the housing.
[0009] Preferably, the handle is threadedly connected with the fixed block, and one side of the movable block abuts against one side of the hose.
[0010] Preferably, one side of the squeezing wheel abuts against one side of the hose, and the squeezing wheel is rotatably connected with the rotating seat.
[0011] Preferably, the eccentric wheel is fixedly connected with the drive shaft. One end of the drive shaft passes through the fixing plate and is fixedly connected with the output end of the micro motor. The other end of the drive shaft extends into the housing and is rotatably connected with the housing.
[0012] Preferably, the connecting shaft is rotatably connected with the fixing rod, and both ends of the connecting shaft are fixedly connected with one side of the fixing plate.
[0013] Preferably, clamping blocks are fixed on both sides of the fixing rod close to one end of the contact head, and clamping grooves are formed inside the contact heads at one end of the fixing rod.
[0014] Preferably, the clamping block and the contact head form a clamping structure through the clamping groove.
[0015] The advantages of a saliva collection device provided by the present invention are as follows: By setting a vibration structure, the drive shaft drives the eccentric wheel to rotate inside the swing frame, causing the swing frame to swing up and down inside the housing. The swing frame will drive the fixed rod to rotate around the connecting shaft through the connecting rod, and then the fixed rod will drive the contact to swing reciprocally outside the housing, so that the contact vibrates inside the oral cavity. The vibration of the contact stimulates the nerve endings on the tongue. When these nerve endings are stimulated, they will transmit signals to the salivary secretion center in the brain. After receiving the signals, this center will issue instructions to prompt the salivary glands to increase the secretion of saliva. At the same time, this vibration stimulation will also trigger some reflex activities to further promote saliva secretion, realizing the function of this device to promote saliva secretion, enabling unconscious patients in critical condition to secrete a large amount of saliva quickly for collection when using it, thus improving the working efficiency of this saliva collection device when in use; Furthermore, the clamping block and the contact are clamped and fixed through the clamping groove, which is convenient for disassembling and assembling the contact, and then selecting a contact with a suitable size according to the age of the patient for use, thereby improving the applicability of this saliva collection device when in use; By setting a collection structure, when the drive shaft rotates, it will drive the rotating seat to rotate inside the limit seat. One end of the rotating seat squeezes the hose through the squeezing wheel, so that the squeezing wheels at both ends of the rotating seat can alternately squeeze the hose to deform when the rotating seat rotates, and the hose discharges and collects the saliva inside the oral cavity, avoiding the accumulation of saliva in the patient's oral cavity and causing choking, thereby improving the safety of this device when in use.
