Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anesthetic dosing device and a dosing component. Background Art
[0002] Anesthetics are a class of drugs used to put patients into an anesthesia state during medical procedures or other situations that require painlessness or loss of consciousness. Anesthetics can produce anesthetic effects through different mechanisms, including inhibiting neurotransmission, reducing nerve excitability, or changing the state of consciousness of the brain. They are one of the important medical means for surgical treatment or other medical examinations and treatments. Its use often requires the cooperation of an anesthesia machine.
[0003] The anesthesia machine needs to be dosed before use, and there are generally two ways of dosing. The first is direct dosing, which is an open dosing method, that is, pouring the anesthetic directly into the vaporizer of the anesthesia machine. Although this dosing method is simple, it is difficult to control the dosage, and a small amount of volatilization will inevitably occur during the dosing process, which will not only cause waste of anesthetics, but also cause environmental pollution, and even threaten the health of medical staff in severe cases. The other is to use a dosing device as an intermediary to add anesthetics to the vaporizer of the anesthesia machine. This dosing device generally uses an internal baffle to form a sealed isolation with the vaporizer. When in use, the internal mechanical structure of the dosing device pierces the baffle to realize the function of adding drugs from the anesthetic bottle to the anesthetic vaporizer. Once the baffle is pierced, this structure cannot interrupt or stop dosing, and the dosage cannot be qualitatively controlled during the dosing process. Utility Model Content
[0004] The embodiment of the utility model provides an anesthetic agent dosing device and a dosing component, which has the function of repeated switching, and is intended to solve the problem that the dosage of anesthetic agents cannot be qualitatively controlled during the process of adding anesthetic agents to the vaporizer of an anesthesia machine, and at the same time can form an effective sealed environment to avoid waste and pollution.
[0005] The embodiment of the utility model is implemented as follows: an anesthetic doser has a shell body with openings at both ends, the upper end of the shell body is used for sealing connection with the anesthetic bottle, and the lower end is used for sealing connection with the vaporizer, including: a limiting component, which is arranged in the shell body and connected to the inner wall of the shell body, and the limiting component has a channel connecting the upper and lower ends of the shell body; and an elastic component, which is accommodated in the shell body, one end of which is connected to the limiting component, and the other end forms a sealing surface with the inner wall of the lower end of the shell body, and the end of the elastic component forming the sealing surface can move axially along the shell body under the action of force.
[0006] Furthermore, the limiting component includes a circular base and an arched portion fixed on the circular base, and the arched portion is provided with a through hole.
[0007] Furthermore, the limiting component is made of rigid material.
[0008] Furthermore, the elastic component includes a sealing block and a compression spring that can move axially along the shell body in the inner cavity of the shell body, one end of the compression spring is connected to the limiting component, and the other end is connected to the sealing block, and the sealing block forms a sealing surface with the inner wall of the lower end of the shell body.
[0009] Furthermore, the sealing block is a push rod, one end of which passes through the through hole to form a guiding fit with the limiting component, and the other end of the push rod is provided with a protrusion, which forms a sealing surface with the inner wall of the lower end of the shell body.
[0010] Furthermore, the bottom diameter of the protrusion is larger than the inner diameter of the opening at the lower end of the shell body.
[0011] Furthermore, the upper end of the shell body is sealed and connected to the anesthetic bottle via an internal thread structure.
[0012] Furthermore, the lower end of the shell body is sealed and connected to the vaporizer via a sealing ring.
[0013] Furthermore, it also includes a gasket arranged on the limiting component.
[0014] The embodiment of the utility model further provides an anesthetic dosing assembly, comprising an anesthetic bottle and the anesthetic dosing device, wherein the anesthetic bottle and the anesthetic dosing device are connected.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] Anesthetics are a special type of medicine commonly used in medical procedures. Since they are often volatile, they are generally required to be added to the anesthesia machine through an intermediary device such as a dosing device for subsequent medical use.
[0022] The dosing devices currently on the market either have complex structures or use a baffle structure to form a sealed cavity. When in use, the baffle structure is punctured by an internal mechanical structure to allow the medicine to pass through. These devices often do not have a reciprocating switch function and cannot qualitatively control the dosage during the dosing process.
[0023] The utility model is proposed to provide a dosing device with a reciprocating switch function that can solve the problem that the dosage of anesthetic cannot be qualitatively controlled during the dosing process of the anesthetic to the anesthesia machine. The following embodiment is a preferred implementation.
[0024] Embodiment 1
[0025] like Figure 1 As shown, an anesthetic agent doser has a shell body 10 with two ends opened, the upper end of the shell body 10 is used to be sealed with an anesthetic agent bottle 70, and the lower end is used to be sealed with an anesthesia machine vaporizer through a sealing ring 20. The doser includes:
[0026] A limiting component 30 is disposed in the housing body 10 and connected to the inner wall of the housing body 10, and the limiting component 30 has a channel connecting the upper and lower ends of the housing body 10; and
[0027] The elastic component is accommodated in the shell body 10, one end of which is connected to the above-mentioned limiting component, and the other end forms a sealing surface with the inner wall of the lower end of the shell body 10. The end of the elastic component forming the sealing surface can move axially along the shell body 10 under the action of force.
[0028] When in use, the anesthetic bottle 70 is fastened to the doser through the limiting component 30 connected to the outer shell body 10 of the doser, and the anesthetic bottle 70 is sealed and fixed to the doser under the action of the limiting component 30. The anesthetic enters the doser through the limiting component 30 with multiple channels. The elastic component 30 forms a sealing surface with the inner wall of the lower end of the outer shell body 10, and then combines with the anesthetic bottle 70 to form a closed cavity inside the doser.
[0029] In this structure, the anesthetic is effectively enclosed in the closed space formed by the dosing device and the anesthetic bottle 70, and is not easy to evaporate or leak, even if the dosing device bottle is turned over or tilted.
[0030] When the medical staff performs the dosing operation, first, the doser with the anesthetic bottle 70 installed is inserted into the vaporizer of the anesthesia machine, and a push rod is generally provided inside the vaporizer of the anesthesia machine. Due to the sealing effect of the sealing ring 20, the doser forms a sealed connection with the vaporizer of the anesthesia machine. The medical staff presses the doser from top to bottom to apply a downward force. Under the reverse push of the push rod inside the vaporizer of the anesthesia machine, the elastic component at the lower end of the doser moves along the axial direction of the shell body 10 and away from the bottle mouth of the vaporizer of the anesthesia machine, thereby opening the lower end opening of the shell body 10, so that the anesthetic in the confined space enters the vaporizer of the anesthetic under the action of gravity, and the addition of the medicine is realized. When the medical staff releases the pressure and lets go of the doser, the elastic component of the doser moves along the axial direction of the shell body 10 and close to the bottle mouth of the vaporizer of the anesthesia machine under the action of its internal elastic force. When the elastic component reaches the inner wall of the lower end of the shell body 10 and forms a sealing surface, it stops moving to close the lower end opening, realizing the function of stopping the addition of the medicine.
[0031] During the whole process, medical staff can flexibly control the switch of the dosing device according to the actual dosage needs during work: press down to start dosing, release to stop dosing, and the anesthetic is sealed in a certain space during the dosing process, which is not easy to volatilize and leak. This structure and operation can effectively ensure the safety of medical staff.
[0032] Embodiment 2
[0033] On the basis of the first embodiment, further, Figure 1 , 2 As shown, the limiting component 30 includes a circular base and an arched portion fixed on the circular base, and the arched portion is provided with a through hole.
[0034] The overall shape of the arched portion is similar to a tall hat, and is provided with multiple channels to facilitate the passage of anesthetics. The number of channels is preferably 3 to form a triangular support, which is convenient for further clamping and stabilizing the anesthetic bottle mouth, especially for some anesthetic bottle mouths made of plastic.
[0035] At the same time, a perforation is also arranged in the center of the arched portion to provide a space for the elastic component to move through, play a role in guiding the movement of the elastic component, and help stabilize the direction of the reciprocating movement of the elastic component.
[0036] In addition, a limiting block may be provided at the central through hole of the arched portion of the limiting component 30 to limit excessive penetration of the elastic component.
[0037] When in use, the limiting component 30, on the one hand, allows the anesthetic agent to pass freely due to its channel structure, and on the other hand, plays a fixing and limiting role, which not only further tightens the bottle mouth of the anesthetic agent to prevent loosening, especially for the plastic bottle mouth of the anesthetic agent, but also provides a guarantee for the movement stability of the elastic component. In addition, the limiting component 30 can also limit the movement depth of the elastic component to prevent the elastic component from damaging the anesthetic bottle 70.
[0038] Embodiment 3
[0039] On the basis of the second embodiment, further, the limiting component 30 is a rigid material. The rigid material is a metal material or a ceramic material. The metal material is steel, iron, aluminum, copper or other alloy materials. The ceramic material is ceramic.
[0040] The limiting component 30 made of rigid material will further strengthen the fastening between the dosing device and the anesthetic bottle 70, and also help to improve the sealing performance.
[0041] In addition, the limiting component 30 and the shell body 10 may be formed into an integral structure by industrial ultrasonic welding.
[0042] The rigid material and the integrally formed structure can make the utility model more convenient to process in industrial manufacturing, and also convenient to install, test and maintain during use.
[0043] Embodiment 4
[0044] On the basis of the second embodiment, the elastic component further includes a sealing block 60 and a compression spring 50 which can move axially along the shell body 10 in the inner cavity of the shell body 10. One end of the compression spring 50 is connected to the limiting component 30, and the other end is connected to the sealing block 60. The sealing block 60 forms a sealing surface with the inner wall of the lower end of the shell body 10.
[0045] The surface contact between the end of the sealing block facing the anesthesia machine vaporizer and the inner edge of the lower opening of the shell body 10 can be a horizontal surface contact or a funnel-shaped surface contact. As long as a surface contact with the inner edge of the lower opening of the shell body 10 can be formed, the effect of forming a rigid sealing surface can be achieved.
[0046] When in use, the medical staff applies external force to cause the sealing block 60 to move along the axial direction of the shell body 10 toward the anesthesia machine bottle, thereby opening the drug adding port; when the external force is released, the sealing block 60 moves toward the anesthesia machine vaporizer under the action of the compression spring 50 until it contacts the inner edge of the lower end opening of the shell body 10, thereby closing the drug adding port.
[0047] By applying and releasing external force, the elastic component cooperates with the lower opening of the shell body 10 under the action of the external force to open and close the dosing port. Such repeated actions realize flexible control of the on and off of the dosing process.
[0048] Embodiment 5
[0049] On the basis of embodiment 4, further, the sealing block arranged in the shell body 10 of the anesthetic dosing device is a push rod, one end of the push rod passes through the through hole of the limiting component 30 to form a guiding fit with the limiting component 30, and the other end of the push rod is provided with a protrusion, which forms a sealing surface with the inner wall of the lower end of the shell body 10.
[0050] The push rod is cylindrical in shape. Figure 1 , 2 As shown, in this embodiment, the push rod is formed integrally by two cylinders of different sizes, wherein the upper end of the push rod is a small cylinder and the lower end is a large cylinder. The small cylinder is used to pass through the through hole, and plays a role in stabilizing the reciprocating motion under the action of the limiting component 30. Since a limiting block is provided at the central through hole of the arched portion of the limiting component 30, the large cylinder can prevent the push rod from excessively passing through because its diameter is larger than the inner diameter of the limiting block.
[0051] By using the push rod structure, in cooperation with the limiting component 30, it helps to stabilize and assist the reciprocating axial movement of the elastic component, and further improves the switch closing stability during the process of adding medicine.
[0052] Embodiment 6
[0053] On the basis of the fourth embodiment, further, as Figure 1 , 2 As shown, a protrusion is provided at the other end of the push rod, and the bottom diameter of the protrusion is larger than the inner diameter of the lower end opening of the shell body 10.
[0054] By forming an interference fit between the protrusion and the lower end opening of the shell body 10 , the push rod is sealed and movably connected to the lower end opening of the shell body 10 under the action of the compression spring 50 .
[0055] The use of a push rod with such a raised structure can further increase the internal space of the dosing device, making it easier and more efficient for the anesthetic liquid to pass through the interior of the dosing device, thereby improving the efficiency of adding the drug.
[0056] Embodiment 7
[0057] On the basis of the first embodiment, further, the upper end of the shell body 10 is sealedly connected to the anesthetic bottle 70 through an internal thread structure.
[0058] By using this structure, the anesthetic agent bottle 70 can be more securely connected to the dosing device.
[0059] It should be noted that not only the internal thread structure, but also other structures that can be used to fasten the bottle mouth can be used in this structure, such as the snap-fit structure.
[0060] Embodiment 8
[0061] On the basis of the first embodiment, further, Figure 1 , 2 As shown, the lower end of the housing body 10 is sealedly connected to the vaporizer via a sealing ring 20 .
[0062] The sealing ring 20 is arranged outside the lower end of the shell body 10 . An annular groove is arranged outside the lower end of the shell body 10 , and the groove is used to place the sealing ring 20 .
[0063] The sealing ring 20 can ensure the sealed connection between the medicine adding device of the utility model and the vaporizer of the anesthesia machine.
[0064] The sealing ring is made of elastic material, such as plastic or rubber.
[0065] Using an elastomeric material can provide a better seal.
[0066] Embodiment 9
[0067] On the basis of the first embodiment, further, a gasket 40 is provided on the limiting component 30, and the material of the gasket is preferably an elastic material, such as plastic or rubber.
[0068] Through the cooperation of the gasket 40 and the limiting component 30, the connection between the anesthetic bottle 70 and the dosing device is not only stable, but also the sealing performance is further enhanced.
[0069] Embodiment 10
[0070] An anesthetic agent dosing assembly comprises an anesthetic agent bottle 70 and the above-mentioned anesthetic agent dosing device, wherein the anesthetic agent bottle 70 is connected to the above-mentioned anesthetic agent dosing device.
[0071] The dosing device provided by the utility model is usually used in conjunction with an anesthetic bottle 70. It can be temporarily connected to the anesthetic bottle 70 when anesthetic needs to be added, and can also be used together with the anesthetic bottle 70 after being integrally connected. The switch function of the dosing device of the utility model replaces the opening, closing and sealing functions of the ordinary anesthetic bottle cap.
[0072] In summary, the use of this dosing device and dosing component not only has the function of repeated switching, and can flexibly control the dosage of the dosing during the dosing process, but also can avoid the volatilization and waste problems during the dosing process and prevent the generation of environmental pollution.
[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
