Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a cervical medication device. Background Art
[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly on the human body, including the required computer software. Medical devices include medical equipment and medical consumables.
[0003] For example, a cervical drug delivery device for gynecological treatment disclosed in announcement number CN212651222U has the following beneficial effects: a drug delivery tube is installed on the drug delivery tube, a belt ring provided on the drug delivery tube can fix the position, and a drug inlet tube and a drug outlet tube provided on the drug delivery tube are respectively convenient for drug inlet and drug outlet, and the drug inlet and drug outlet can be controlled by a manual drug inlet switch valve and a manual drug outlet switch valve, and a push rod inserted in the drug delivery tube can conveniently push the drug liquid to the application head screwed on the connecting tube, because the application head can apply the drug liquid to the cervical lesion site, it is easy to use; the drug delivery device is convenient for drug delivery, easy to push and deliver the drug, simple to feed and discharge the drug, and can deliver the drug to the cervical lesion site when administering the drug to the cervix, reducing the difficulty of work for medical staff. ; However, the above patent lacks a structure for heating and stirring the medicine liquid. First, if the medicine liquid is too cold and used directly, it may cause unnecessary stimulation to the patient, especially for certain sensitive parts or patients with weak constitutions. The stimulation of cold medicine liquid may cause discomfort or even pain, which will undoubtedly reduce the patient's comfort; secondly, the medicine liquid may precipitate during use. This may be due to the limited solubility of the drug components in the medicine liquid, or the gradual sedimentation of the drug particles due to long-term standing. If there is no stirring structure, these precipitates may not be evenly dispersed in the medicine liquid, resulting in differences in drug concentration when administering the drug. This unevenness not only affects the absorption and distribution of the drug in the patient's body, but may also reduce the efficacy of the drug.
[0004] Therefore, there is an urgent need for a cervical drug delivery device to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a cervical medication device, which has the advantage of being able to heat and stir the medicine liquid, and solves the problems raised by the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cervical drug delivery device, comprising: an outer tube, the inner cavity of the outer tube is slidably connected to a piston, the left side of the piston is fixedly connected to a push rod, the left end of the push rod extends to the outside of the outer tube and is fixedly connected to a round block, the right end of the outer tube is connected to a drug outlet tube, and the right end of the drug outlet tube is connected to an applicator head.
[0007] A placement groove is provided on one side of the outer tube, an electric heater is provided in the inner cavity of the placement groove, a mounting block matching the placement groove is provided on the left side of the outer tube, and a battery used in conjunction with the electric heater is fixedly connected to the bottom of the outer tube surface.
[0008] The inner cavity of the push rod is fixedly connected to a micro motor, the output shaft of the micro motor is fixedly connected to a rotating rod, the surface of the rotating rod is movably connected to a sleeve, guide grooves are provided on both sides of the inner cavity of the sleeve, the inner cavity of the guide groove is slidably connected to a guide block, one side of the guide block is fixedly connected to the rotating rod, the inner cavity of the push rod and the top of the micro motor is fixedly connected to a micro electric telescopic rod, the output end of the micro electric telescopic rod is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to a rotating block, the inner wall of the rotating block is rotatably connected to the sleeve, and one side of the sleeve extends to the inner cavity of the piston and is fixedly connected to a stirring block.
[0009] Furthermore, as a preferred embodiment of the present invention, the outer tube, the piston, the push rod, the round block, the medicine outlet tube and the applicator head together constitute a cervical drug delivery device.
[0010] Furthermore, as a preferred embodiment of the present invention, a through hole is opened on the left side of the outer tube, and the push rod is located in the inner cavity of the through hole and is slidably connected to the through hole.
[0011] Furthermore, as a preferred embodiment of the present invention, a liquid injection hole is provided at the top of the outer tube, and a sealing plug is provided in the inner cavity of the liquid injection hole.
[0012] Furthermore, as a preferred embodiment of the present invention, the surface of the mounting block is provided with an external thread, and the inner wall of the placement groove is provided with an internal thread matching the external thread.
[0013] Furthermore, as a preferred embodiment of the present invention, a sealing ring is sleeved on one side of the sleeve surface, and one side of the sealing ring is fixedly connected to the piston.
[0014] Beneficial effects: The technical solution of the present application has the following technical effects: the utility model has the advantage of being able to heat and stir the drug solution. In actual use, firstly, by heating the drug solution in the inner cavity of the outer tube, it can effectively prevent the drug solution from being too cold and causing unnecessary stimulation to the patient. By appropriate heating, the stimulation to the patient's skin can be reduced, which is beneficial to improving the patient's comfort. Moreover, heating the drug solution can also promote the dissolution of the drug. Heating can increase the movement speed of the solvent molecules, making it easier for the drug molecules to interact with the solvent molecules, thereby improving the solubility of the drug. The increase in solubility means that more drug components can be dissolved. In the drug solution, it is necessary to ensure the accuracy and stability of the drug concentration when administering the drug, thereby improving the therapeutic effect. Secondly, it is also very important to stir the drug solution. By stirring the drug solution in the inner cavity of the outer tube, it is ensured that the heat of the drug solution is evenly distributed, so that the heat is more evenly transferred to each part, reducing local overheating or overcooling. At the same time, stirring can also ensure that the drug components in the drug solution are evenly distributed. During the static state of the drug solution, the drug components may gradually settle due to gravity, resulting in uneven drug concentration. Stirring can break this sedimentation phenomenon, so that the drug components are redispersed evenly in the drug solution, avoiding the problems caused by drug precipitation.

The sleeve 13 will drive the stirring block 18 to rotate when it rotates. The rotation of the stirring block 18 makes the heat of the medicine more uniform, avoids the aggregation or precipitation of particles or components in the medicine solution, and thus maintains the uniformity of the medicine solution; finally, the outer tube 1 is in a vertical state, the micro-electric telescopic rod 16 is started, and the output end of the micro-electric telescopic rod 16 is contracted to drive the stirring block 18 to retract into the inner cavity of the piston 2, and then the outer tube 1 is used to move the application head 10 to the place where the medicine needs to be applied, and the round block 4 is pushed. The round block 4 drives the piston 2 to push the medicine through the transmission of the push rod 3. At this time, the medicine enters the cervical lesion site through the medicine outlet tube 9 and the application head 10, and the medicine application operation can be completed.
