Description

Medical equipment and medical auxiliary device

Technical Field

The invention relates to the technical field of medical instruments, in particular to medical equipment and a medical auxiliary device.

Background

For diabetic users, measuring blood glucose levels is an indispensable daily matter. Currently, a common measurement method in the market is to collect fingertip blood and measure blood glucose value by using a finger blood glucometer. However, this test method is very limited because it can only measure the blood glucose level of a user at a single point in time, and cannot continuously monitor the blood glucose level. CGM (Continuous Glucose Monitoring) was carried out for this defect. The principle of CGM is that glucose concentration of subcutaneous interstitial fluid is monitored through a glucose sensor, and a monitoring technology for indirectly reflecting blood glucose level can continuously provide blood glucose information throughout the day, know the trend of blood glucose fluctuation and provide a very effective judgment basis for doctors to diagnose and treat users.

Because the pins of the glucose sensor need to be implanted under the skin of the human body and remain for the entire monitoring period (typically 7-14 days). To minimize the pain and discomfort experienced by the user of the implanted portion, the sensor pins need to be small in size and flexible (typically plastic). Therefore, in order for the sensor pin to pierce the epidermis of the user and be implanted under the skin of the user, an auxiliary tool is required: a needle assisting device. The existing CGM products are quite complex in structure, high in manufacturing cost, tedious in using steps of users and unfriendly to users, once the using steps are wrong, the whole CGM product is scrapped, the operation requirement on the users is high, and the use experience is poor.

The medical device comprises a medical auxiliary device and a medical device, wherein the medical device is used for being jointed with the medical auxiliary device so as to load a target object in the medical device through the medical auxiliary device and at least partially implant the target object into a preset object. In some embodiments, in use, the medical device is secured to the predetermined subject by the medical assist device.

The disclosed medical assist device relates to a base for loading a medical device and implanting a target object in the medical device at least partially into the skin of a user. The medical assist device disclosed herein is configured to at least partially insert various objects into the body of the intended subject, including but not limited to, analyte sensors, as well as other devices such as cannulas, infusion devices. The medical assist device may mount the medical device on, under, or through the skin of the subject, or place the medical device on the skin surface.

The medical devices disclosed herein relate to targets, which may be analyte sensors, as well as other devices such as cannulas, infusion sets, etc., for at least partial implantation into human skin. In some embodiments disclosed herein, the invention relates to a medical device for detecting at least one analyte (e.g., glucose) in blood or other bodily fluids, and thus, embodiments include an analyte sensor configured such that at least a portion of the analyte sensor is positioned within a body of a user to obtain information about the at least one analyte of the body, e.g., percutaneously positioned in the body of the user.

A preferred embodiment of a medical assist device 100 and a medical device 200 engaged with the medical assist device 100 is shown in fig. 1, and an axial cross-sectional view of the medical assist device 100 engaged with the medical device 200 is shown in fig. 2.

As shown in fig. 1 and 2, a preferred embodiment of the present invention provides a medical apparatus including a medical assistance device 100 and a medical device 200. Wherein the medical assistance device 100 comprises a housing assembly comprising an outer housing 1 and an inner housing 2, the medical assistance device 100 further comprising an insertion member 3 and an energy storage member 4. The inner shell 2 and the outer shell 1 can move relatively, and the energy storage component 4 is arranged in the inner shell 2 and connected with the outer shell 1. The energy storage member 4 is used to store elastic potential energy in an initial position, i.e. the energy storage member 4 is compressed to store elastic potential energy in the initial position. It should be understood that the base portion of the outer casing 1 is disposed outside the inner casing 2, for example, the outer casing 1 for a user to hold is partially sleeved on the inner casing 2, and another portion is disposed inside the inner casing 2 so as to be connected with the energy storage member 4, but the positional relationship between the inner casing 2 and the outer casing 1 will change with the relative movement of the inner casing 2 and the outer casing 1, so that the inner casing 2 will partially protrude from the outer casing 1 or be entirely accommodated in the outer casing 1, and therefore, the inner casing 2 is not absolutely limited to be entirely inside the outer casing 1.

A preferred embodiment of a medical device 200 is shown in fig. 3 and 11. The medical device 200 comprises a base 5, electronic components 7 and an analyte sensor 8. Wherein the medical device 200 needs to be secured to, and typically adhered to, human skin. The analyte sensor 8 is preferably arranged fixedly in a detachable manner on the base 5, the base 5 being configured as a structure with a cavity, the analyte sensor 8 being accommodated in the cavity of the base 5. In some embodiments, the base 5 and the analyte sensor 8 are snap-fit or otherwise connected. The analyte sensor 8 comprises an insertion portion 81, the insertion portion 81 being understood as a sensor pin. The insertion portion 81 is used to enter the skin of a predetermined subject to establish fluid contact. The electronic component 7 is mainly fixedly arranged on the base 5 in a detachable manner and is in communication connection with the analyte sensor 8, and the electronic component 7 is a reusable component. In some embodiments, the electronic components 7 are configured as components for wirelessly transmitting data collected by the analyte sensor 8. In some embodiments, the electronic component 7 wirelessly transmits the analyte-related data upon receiving an external command. In certain embodiments, electronics 7 may include control logic or a microprocessor that may process based on information obtained from analyte sensor 8 to obtain relevant analytical results.

In view of the high cost of the electronic part 7, for this reason, the electronic part 7 is configured as a recyclable part; the medical aid 100 and the base 5 are relatively inexpensive to manufacture, and the insertion member 3 and the insertion portion 81 of the analyte sensor 8 need to pierce the skin of the human body, and therefore need to be sterilized. As shown in fig. 20, the medical apparatus may further include a sterilization case 910 for housing the medical auxiliary device 100 and the medical apparatus 200 and providing a sterilized storage environment. In one embodiment, the medical accessory device 100 and the base 5 may be sterilized and then placed in the sterilization case 910, and the sterilization case 910 may be opened again when percutaneous injection is required and then removed for direct installation. And the ordinary user does not have the conditions to sterilize them, the medical aid 100, the base 5, and the analyte sensor 8 are all disposable elements. It will also be appreciated that some of the components may be recycled and another part may be a single use product, such that the medical device 200 of the present invention is a semi-reusable medical device and the medical aid 100 is a single use device. Of course, it will be understood by those skilled in the art that the medical aid device 100 of the invention may also carry the assembled electronic component 7 and the chassis 5 directly, i.e. after a transcutaneous injection, the medical device 200 as a whole is mounted directly on, under or through the skin of the subject, or the medical device 200 is placed on the skin surface.

Fig. 4 and 5 show that the insertion part 3 is arranged on the energy storage part 4, and the energy storage part 4 is arranged in the inner housing 2 and connected to the outer housing 1. Specifically, in fig. 5, the energy storage member 4 is fixed at an initial position where the energy storage member 4 is compressed to store elastic potential energy. In use, the outer housing 1 and the inner housing 2 can move relative to each other as shown in fig. 2 and 5. Specifically, in the initial state determined by the initial position, the distal end 23 of the inner shell 2 extends downward beyond the distal end of the outer shell 1, and in the specific operation, only the protective cover needs to be removed, then the distal end 23 of the inner shell 2 abuts against the epidermis, and then the outer shell 1 is pressed downward by a user's hand or an external mechanism, so that the insertion component 3 can be triggered by the outer shell 1, the insertion component 3 and the energy storage component 4 are driven to move downward together from the initial position (i.e., move in the proximal-to-distal direction), and the inner shell 2 cannot move because the distal end 23 is already fixed relatively on the skin of the human body. The insertion member 3 eventually pierces the skin of the human body and when the outer housing 1, the insertion member 3 and the energy storage member 4 move down to a predetermined position, the energy storage member 4 releases its elastic potential energy, thereby forcing the insertion member 3 to move up (i.e. in a distal to proximal direction), as shown in fig. 6, causing the insertion member 3 to retract back into the inner housing 2.

A preferred embodiment of the insert part 3 is further shown in fig. 12. The insertion member 3 may include a base portion 31 and a needle portion 32, the base portion 31 being connected with the energy storage member 4, the needle portion 32 being connected with the base portion 31. In some embodiments, the needle portion 32 is a solid needle, such as by inserting the needle portion 32 into a cannula. In some embodiments, as shown in FIG. 12, the needle portion 32 is a hollow needle provided with a substantially cylindrical configuration defining an internal bore. The needle portion 32 may also be provided with an elongated longitudinal opening or gap in the wall. In certain embodiments, the needle portion 32 is fabricated from sheet metal and bent into a "V" or "U" or "C" shaped configuration in cross-section to define a longitudinal gap or opening for receiving the insertion portion 81 of the analyte sensor 8. Further, the energy storage component 4 is a spring, and the spring is sleeved on the base 31, wherein one end of the spring is embedded in the base 31, and the other end of the spring is connected with the housing 1.

The position of the insertion part 81 of the analyte sensor 8 and the insertion part 3 is shown in fig. 13. The needle portion 32 of the insertion member 3 has a longitudinal opening or a longitudinal gap that partially covers the insertion portion 81 of the analyte sensor 8, such that during downward movement of the insertion member 3, loading of the insertion portion 81 by the needle portion 32 implants the insertion portion 81 at least partially under the skin of the human body, and when the energy storage member 4 rebounds, the insertion member 3 is driven by the energy storage member 4 to move upward, causing the needle portion 32 to move away from the skin of the human body, leaving the insertion portion 81 under the skin of the human body, which is done instantaneously, such that the user does not significantly feel pain.

When the energy storage component 4 rebounds to the balance position, the medical auxiliary device 100 is separated from the base 5 of the medical device 200, and the base 5 is stuck and fixed on the skin of the human body. In this embodiment, the base 5 is detachably connected to the housing 1 in advance, and the detachable connection manner is not limited. In some embodiments, after the base 5 is fixed on the skin of the human body, the electronic component 7 is assembled on the base 5, so that the collection of the glucose concentration data of the subcutaneous interstitial fluid can be started, and the data is transmitted to a terminal device, such as a mobile phone APP or other handheld device, through the electronic component 7 by using a wireless communication technology for data conversion and display.

Therefore, the medical aid device 100 of the present invention accomplishes the transportation of the insertion portion 81 of the analyte sensor 8 under the skin of the human body and the instant rebound of the insertion member 3 by the relative movement of the inner and outer cases, while the insertion portion 81 remains under the skin of the human body, in such a manner as to achieve the implantation of the target, not only having a simple structure and a low manufacturing cost, but also being simple and convenient to operate, being less prone to error when used by the user, reducing the risk of operation error, and also reducing the risk of product rejection.

The medical assist device 100 can also include a locking member that includes a first locking structure disposed on the housing 1. The first locking structure is used for locking the energy storage component 4 at an initial position, and when the insertion component 3 and the energy storage component 4 move downwards to a preset position, the first locking structure can release the locking of the energy storage component 4, so that the energy storage component 4 releases elastic potential energy.

Fig. 4 to 6, and 8 show a first locking structure of a preferred embodiment. The first locking structure comprises at least two resilient jaws 11, the at least two resilient jaws 11 being symmetrically arranged on the outside of the insertion part 3. At least two elastic jaws 11 simultaneously seize or hold the insertion member 3 so that the energy storage member 4 is pressed by the insertion member 3 to compress and fix the energy storage member 4 at an initial position. In the present embodiment, the number of the elastic claws 11 is preferably three, and three of the elastic claws 11 are uniformly arranged in the circumferential direction of the insertion part 3, which makes it possible to more reliably fix the insertion part 3. Preferably, the deformation force of the elastic claw 11 is smaller than the compression resilience force of the energy storage component 4, so that the energy storage component 4 can automatically overcome the deformation force of the elastic claw 11 to release elastic potential energy, and the structure can further simplify the structure and simplify the operation steps. Of course, the application is not limited to fixing the initial position of the energy storage member 4 by means of the elastic claws 11, but the object can also be achieved by other mechanical, electrical or magnetic means, etc. And when the elastic clamping jaw 11 is adopted for clamping, the deformation force of the elastic clamping jaw 11 can also be larger than the compression resilience force of the energy storage component 4, at the moment, the elastic clamping jaw 11 can be automatically opened and closed through a certain control means, and the energy storage component 4 can also be fixed and unlocked.

Further, the locking member may further include a second locking structure provided on the inner case 2. In the process that the inserting component 3 and the energy storage component 4 move downwards to the preset position, the second locking structure is used for being matched and connected with the first locking structure, so that the energy storage component 4 is always locked at the initial position by the first locking structure, and the energy storage component 4 is ensured not to release elastic potential energy in the process; when the insertion component 3 and the energy storage component 4 move downwards to the preset position, the second locking structure is disconnected with the first locking structure, so that the first locking structure is unlocked from the energy storage component 4, and the energy storage component 4 can release elastic potential energy.

In some embodiments, the second locking structure comprises an abutment for abutting the elastic claw 11, preventing the elastic claw 11 from bending outwards if the deformation force is smaller than the compression resilience of the energy storage component 4.

Referring to fig. 5 and 6, in some embodiments, the stopping portion is configured as a clasping annular structure 22, the clasping annular structure 22 is disposed at the proximal end 21 of the inner shell 2 and extends downward to form an annular side wall, and an inner annular surface of the annular side wall can simultaneously abut against all the elastic claws 11, so that the structure is simple and the operation is more convenient. During the downward movement of the insertion part 3 and the energy storage part 4, the inner annular surface of the clasping loop structure 22 always abuts against the elastic claw 11. As shown in fig. 5, in the initial position, the elastic claws 11 are surrounded by the clasping ring structure 22, and when the insertion member 3 and the energy storage member 4 move downward until the elastic claws 11 are separated from the clasping ring structure 22, because the compression resilience of the energy storage member 4 is greater than the deformation force of the three elastic claws 11, the three elastic claws 11 automatically bend outward and deform without being constrained by the clasping ring structure 22, so that the insertion member 3 is released, and the insertion member 3 can retract into the inner shell 2, that is, as shown in fig. 6, thereby avoiding the sharp insertion member 3 from accidentally injuring a user or other persons.

In this embodiment, the elastic claws 11 are integrally formed with the outer shell 1, and the clasping ring structure 22 is integrally formed with the inner shell 2.
