Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a gynecological quantitative dosing device. Background Art

[0002] Gynecology is a professional department that diagnoses and treats female gynecological diseases. Gynecological diseases include: diseases of the female reproductive system, including vulvar diseases, vaginal diseases, uterine diseases, fallopian tube diseases, ovarian diseases, etc. In medicine, women's diseases are the research object, and drug delivery devices are often used to treat patients.

[0003] In the process of gynecological treatment, in order to avoid the risk of cross infection or drug contamination, the design of the drug dispenser is often disposable. This type of drug dispenser usually pre-loads the drug in the drug delivery tube for direct drug delivery. However, although the drug dosage in the drug delivery tube is pre-set, in fact, the drug dosage required by the patient varies according to his or her own condition, and does not always correspond exactly to the pre-loaded amount of drug in the drug delivery tube. This difference leads to the fact that in the actual drug delivery process, patients can only decide how much drug to use based on personal judgment and experience, making it difficult to achieve accurate control of the drug dosage. This rough dosage control can easily lead to excessive or insufficient dosage, thereby affecting the treatment effect, which may not only lead to insufficient drug efficacy and delay recovery of the disease, but also may cause unnecessary side effects or drug waste due to excessive administration.

[0023] A gynecological quantitative drug delivery device, such as Figure 1-4 As shown, it includes: a dosing tube 100, a fixing plate 110, an annular groove 120, a drug outlet 130, a quantitative piece 140, a positioning mechanism 200, a sealing mechanism 300 and a push rod mechanism 400; the fixing plate 110 is fixedly connected to the dosing tube 100; the annular groove 120 is opened on the dosing tube 100; the drug outlet 130 is opened on the side of the dosing tube 100 away from the fixing plate 110; the quantitative piece 140 is arranged in the annular groove 120; two positioning mechanisms 200 are symmetrically arranged on the fixing plate 110, and the two positioning mechanisms 200 are both arranged in cooperation with the quantitative piece 140; the sealing mechanism 300 is arranged on the dosing tube 100; and the push rod mechanism 400 is movably connected to the dosing tube 100.

[0024] In order to achieve accurate drug dosage, an annular groove 120 is provided in the drug delivery tube 100. When preparing to administer the drug, the patient pulls out the quantitative member 140 from the annular groove 120 according to the required dosage according to the doctor's prescription or treatment needs to reach the preset drug amount. Subsequently, the position of the quantitative member 140 is accurately fixed by the positioning mechanism 200 to ensure the accuracy of the drug dosage during the drug delivery process. When the quantitative setting is completed, the operator inserts the push rod mechanism 400 into the drug delivery tube 100, and by pushing downward, the drug begins to move downward along the drug delivery tube 100 until the push rod mechanism 400 is pushed downward. The push rod mechanism 400 contacts the previously fixed metering member 140. At this time, due to the obstruction of the metering member 140, the push rod mechanism 400 cannot continue to move downward, indicating that the predetermined dose of medicine has been completely pushed out of the dosing tube 100, completing an accurate drug dosing process; in order to prevent the need for drug leakage or contamination, the device is specially equipped with sealing mechanisms 300 at both ends of the dosing tube 100, and the sealing mechanism 300 ensures that the medicine in the dosing tube 100 is completely sealed, which not only prevents any leakage of the medicine, but also maintains the quality and safety of the medicine, and ensures that the efficacy of the medicine is not affected by the external environment.

[0025] In the embodiment of the present utility model, Figure 1-4 As shown, the quantitative member 140 includes: a pull-out tube 141, a scale line 142 and a baffle 143; the pull-out tube 141 is slidably connected to the annular groove 120; the scale line 142 is arranged on the pull-out tube 141; and the baffle 143 is fixedly connected to the pull-out tube 141 on one side close to the fixed plate 110.

[0026] In the embodiment of the present utility model, Figure 1-4 As shown, the positioning mechanism 200 includes: a fixed block 210, a limiting hole 220, an insert rod 230, a limiting ring 240, a spring 250 and a socket 260; the fixed block 210 is fixedly connected to the fixed plate 110; the limiting hole 220 is opened in the fixed block 210; the insert rod 230 is limitedly slidably connected to the limiting hole 220; the limiting ring 240 is fixedly sleeved on the insert rod 230; one end of the spring 250 abuts against the inner wall of the limiting hole 220, and the other end of the spring 250 abuts against the limiting ring 240; a plurality of sockets 260 are all opened on the pulling tube 141, and the insert rod 230 is inserted into the socket 260.

[0027] First, use two fingers to pull the two insertion rods 230 out of the socket 260. At this time, the limiting ring 240 squeezes the spring 250. Then, according to the doctor's prescription or treatment needs, the patient pulls out the pull-out tube 141 from the annular groove 120 according to the required dosage, and uses the scale line 142 to reach the preset amount of medicine. Subsequently, the two insertion rods 230 are released. Under the elastic force of the spring 250, the insertion rods 230 on both sides respectively enter the socket 260 on the pull-out tube 141, thereby fixing the position of the pull-out tube 141 and the dosing tube 100, and then the dosage is determined, thereby ensuring the accuracy of the dosage during the drug administration process and ensuring the therapeutic effect.

[0028] In the embodiment of the present utility model, Figure 1-4 As shown, the sealing mechanism 300 includes: a first sealing block 310, a sealing cap 320 and a second sealing block 330; the first sealing block 310 is arranged in the drug delivery tube 100; the sealing cap 320 is sleeved on the side of the drug delivery tube 100 close to the drug outlet 130; the second sealing block 330 is fixedly connected to the inner side of the sealing cap 320, and the second sealing block 330 is embedded in the drug outlet 130.

[0029] By disposing a first sealing block 310 on the inner wall of the dosing tube 100 and a second sealing block 330 at the drug outlet 130, the drug in the dosing tube 100 is sealed and preserved, ensuring that the drug in the dosing tube 100 is completely sealed, thereby preventing any leakage of the drug, maintaining the quality and safety of the drug, and ensuring that the efficacy of the drug is not affected by the external environment.

[0030] In the embodiment of the present utility model, Figure 1-4 As shown, the push rod mechanism 400 includes: a push rod 410 and a push plate 420 ; the push rod 410 is movably connected to the medication tube 100 ; and the push plate 420 is fixedly connected to the push rod 410 .

[0031] By movably connecting the push rod 410 with the dosing tube 100, the push rod 410 is not in the dosing tube 100 when not in use, thereby preventing the push rod 410 from being pushed when not in use, causing the drug in the dosing tube 100 to leak out. When in use, the push rod 410 is inserted into the dosing tube 100. After the quantitative setting is completed, the patient pushes the push rod 410 to move downward, and the drug begins to move downward along the dosing tube 100 until the push plate 420 on the push rod 410 contacts the baffle 143 on the previously fixed pull-out tube 141. Due to the obstruction of the baffle 143, the push rod 410 cannot continue to move downward, indicating that the predetermined dose of drug has been completely pushed out of the dosing tube 100, thereby completing an accurate drug dosing process.

[0032] In the embodiment of the present utility model, Figure 1-4 As shown, it also includes: a bevel 150; the bevel 150 is arranged on a side of the dosing tube 100 close to the fixing plate 110.

[0033] The bevel 150 is provided on the medication tube 100 , so that the push rod 410 can smoothly enter the medication tube 100 .

[0034] Implementation process: First, use two fingers to pull the two insertion rods 230 out of the insertion holes 260. At this time, the limiting ring 240 squeezes the spring 250. Then, according to the doctor's prescription or treatment needs, the patient pulls the pull-out tube 141 out of the annular groove 120 according to the required dosage, and uses the scale line 142 to reach the preset drug amount. Then, release the two insertion rods 230. Under the elastic force of the spring 250, the insertion rods 230 on both sides enter the insertion holes 260 on the pull-out tube 141 respectively, thereby fixing the position of the pull-out tube 141 and the drug delivery tube 100, and then the drug delivery amount is set. The push rod 410 is then inserted into the dosing tube 100. When the quantitative setting is completed, the patient pushes the push rod 410 to move downward, and the drug begins to move downward along the dosing tube 100 until the push plate 420 on the push rod 410 contacts the baffle 143 on the previously fixed pull-out tube 141. Due to the obstruction of the baffle 143, the push rod 410 cannot continue to move downward, indicating that the predetermined dose of the drug has been completely pushed out of the dosing tube 100, thereby completing an accurate drug dosing process.

[0035] It should be noted that the specific model and specifications of the spring 250 need to be selected and determined based on the actual specifications of the device, so they will not be described in detail.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
