Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fingertip oximeter fixator which is convenient to wear. Background Art

[0002] An oximeter is a small medical device that can monitor the oxygen content in the body's blood in real time through a detector or sensor without blood sampling. It measures indicators such as human blood oxygen saturation, pulse rate, and perfusion index. The principle is to use two different wavelengths of light to pass through body tissues, and then detect the transmitted light signal through a photosensitive sensor. According to the different absorption rates of oxyhemoglobin and reduced hemoglobin to these two lights, the pulse oxygen saturation and pulse rate values are calculated. With the development of technology and the increasing attention of people to their own health, the number of users of home oximeters has gradually increased. For the convenience of use, home oximeters have developed into finger clip oximeters, which are generally divided into an upper clip and a lower clip. The upper and lower clips are connected by a rotating shaft and a torsion spring, and can be directly clamped on the user's fingertip during use.

[0003] However, in the actual use process, since it is necessary to keep the blood flow of the tested finger normal, the clamping force of the oximeter on the finger cannot be too large, which makes the fixing effect of the oximeter on the finger poor. During the measurement process, when the user's arm or hand makes a large movement, the oximeter is likely to shift or fall off, which brings inconvenience to the measurement. At the same time, the oximeter itself has a certain gravity, and when clamped on the hand for a long time, it causes a certain burden on the user's hand, and the comfort of the user is relatively low. Therefore, the present application provides a fingertip oximeter fixator that is convenient to wear to meet the needs. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a fingertip oximeter fixator that is convenient to wear to solve the problems of displacement and falling off caused by the insecure fixation of the existing oximeter.

[0033] As Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a fingertip blood oxygen meter holder that is convenient to wear, including a finger clip type blood oxygen meter body 1. A fixing base 4 for cooperation in fixing is fixedly connected to the bottom of the blood oxygen meter body 1. The blood oxygen meter body 1 can be bound to the wrist part in cooperation with the holder, which is convenient for carrying and using the blood oxygen meter body 1, and can prevent the blood oxygen meter body 1 from falling off due to excessive shaking of the patient. The fixing base 4 is a square block structure. An assembly hole 10 is opened on the side surface in the length direction of the fixing base 4. The assembly hole 10 penetrates through the fixing base 4. One end opening of the assembly hole 10 is in a V-shaped structure, which is convenient for the support bar 3 to be quickly inserted into the assembly hole 10 for cooperation with the fixing base 4. A locking part 11 is opened at the top of the inner side wall of the assembly hole 10. The locking part 11 is in a V-shaped structure and is far from the V-shaped opening end. A locking hole 12 is opened at the bottom of the fixing base 4. The locking hole 12 is communicated with the assembly hole 10 and is close to the side of the locking part 11. The holder includes a fixing sleeve 2 and a support bar 3. The support bar 3 is inserted into the fixing sleeve 2 to support it. Self-adhesive straps 7 and fixing buckles 8 are respectively fixedly connected to the opposite sides of the fixing sleeve 2. The fixing sleeve 2 can be bound to the patient's wrist through the cooperation of the self-adhesive strap 7 and the fixing buckle 8.

[0034] As Figure 1 and Figure 2 shown, the fixing sleeve 2 includes a wrist sleeve 6 in an oval structure. The self-adhesive strap 7 and the fixing buckle 8 are respectively sewn at both ends of the wrist sleeve 6. The back of the self-adhesive strap 7 is respectively pasted with the smooth surface and the rough surface of the magic tape. When in use, the self-adhesive strap 7 is passed through the fixing buckle 8 and then folded back, so that the smooth surface and the rough surface of the magic tape on the self-adhesive strap 7 are pasted, and then the wrist sleeve 6 is bound to the user. A connecting sleeve 5 is fixedly connected to one side of the wrist sleeve 6. The connecting sleeve 5 is a long strip structure and is communicated with the wrist sleeve 6. An elastic part 9 is arranged in the middle of the connecting sleeve 5, which can be used to adjust the length of the connecting sleeve 5 to be suitable for different patients. The whole fixing sleeve 2 is made of flexible materials, preferably made of cloth with a mesh surface on the inner layer, which can buffer the support bar 3 and has good air permeability, improving the comfort of the user.

[0035] As Figure 3 and Figure 5As shown, the support bar 3 is in a T-shaped structure and is compatible with the structure of the fixing sleeve 2. During manufacturing, the support bar 3 is directly placed inside the fixing sleeve 2, and the edges of the fixing sleeve 2 are completely closed to prevent the support bar 3 from detaching from the fixing sleeve 2. Since the fixing sleeve 2 is made of a flexible material, it can effectively fit the structural shape of the fixing sleeve 2 without affecting the use of the fixing sleeve 2 in conjunction with the oximeter body 1. The end of the support bar 3 is a wrist support portion 14, and side wing support plates 15 are symmetrically fixedly connected to both sides of the wrist support portion 14. The side wing support plates 15 are arc-shaped plate structures, and the two groups of side wing support plates 15 are bent inwardly, which can exert a certain clamping force on the wrist when worn on the wrist, thereby increasing the stability of the fixer. A telescopic portion 13 is provided in the middle of the support bar 3. The telescopic portion 13 is in a corrugated structure, and the length of the support bar 3 can be changed by force. It has a telescopic function and can be adapted to the hand structures of different users. A vertical groove can also be provided on the telescopic portion 13, and the groove runs through the entire telescopic portion 13, which can be used to enhance the supporting force at the position of the telescopic portion 13.

[0036] like Figure 4 and Figure 5 As shown, a locking hook 17 is provided at the other end of the support bar 3, and a locking protrusion 16 is provided on one side of the locking hook 17. The locking protrusion 16 is adapted to the locking portion 11. The support bar 3 is an integrally formed structure as a whole and is an elastic special-shaped plate. The support bar 3 is inserted into the fixing sleeve 2, and the edge of the fixing sleeve 2 is sewn so that the fixing sleeve 2 completely wraps the support bar 3. Since the fixing sleeve 2 is made of a flexible material, the structure of the fixing sleeve 2 can be changed accordingly without affecting the matching connection between the support bar 3 and the oximeter body 1. At the same time, the fixing sleeve 2 has a buffering effect on the support bar 3 to avoid the support bar 3 being too hard and causing the patient's comfort to be reduced. When in use, the end of the support bar 3 with the locking hook 17 is inserted from the V-shaped opening end of the assembly hole 10, and the locking hook 1 is pushed 7 to the position of the locking hole 12, during the movement of the locking hook 17, the space of the assembly hole 10 gradually shrinks, causing compression on the locking hook 17 and the locking protrusion 16, causing the locking protrusion 16 and the locking hook 17 to deform. When the locking hook 17 reaches the position of the locking hole 12, the pressure at the locking hook 17 is reduced due to the sudden increase in space, and the free end of the locking hook 17 enters the locking hole 12 and hooks the side of the locking hole 12, thereby achieving the purpose of fixing the base 4. When the locking hook 17 reaches the position of the locking hole 12, the locking protrusion 16 is just at the locking portion 11, and the pressure at the locking protrusion 16 also decreases. The deformation of the locking protrusion 16 begins to recover, thereby causing the locking protrusion 16 to be embedded in the locking portion 11, further locking the fixed base 4 and the support bar 3.

[0037] The working principle provided by the present utility model is as follows. In the normal state of the fixing sleeve 2, both the assembly hole 10 and the wrist support portion 14 remain in the state of a cylindrical structure. And the locking portion 11 on one side of the assembly hole 10 is fixedly connected to the wrist sleeve 6. Then, the end of the fixing sleeve 2 with the wing support plate 15 is led to pass through the connecting sleeve 5 above the oximeter body fixator: 1 in sequence, pass under the oximeter body fixator: 1, and then pass out from another set of connecting sleeves 5 on the same side. During use, the caregiver needs to first guide the patient's hand through the drum formed by the assembly hole 10, and then pull the locking hole 12 to appropriately reduce the drum of the assembly hole 10 so that the size between the drum and the patient's wrist can accommodate two fingers. After adjusting the tightness of the wrist, the elastic portion 9 in the connecting sleeve 5 close to the wrist sleeve 6 is matched with the telescopic portion 13 on the closest locking hole 12 to lock the size of the drum of the assembly hole 10, thereby maintaining the stable restraint of the assembly hole 10 on the patient's wrist. Subsequently, the patient's arm is inserted into the drum formed by the wrist support portion 14, and then the locking portion 11 and the locking hole 12 on one side of the wrist support portion 14 are pulled to appropriately reduce the drum of the wrist support portion 14 so that the size between the drum and the patient's shoulder can accommodate two fingers. After adjusting the tightness of the shoulder, first insert the telescopic portion 13 at a suitable position on the locking hole 12 into the elastic portion 9 on the connecting sleeve 5 through which it passes to lock the other end of the locking hole 12, and then buckle the wing support plate 15 with the fixing buckle 8 at a suitable position to achieve the complete fixation of the wrist support portion 14 and complete the complete locking of the fixing sleeve 2.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above are only the preferred embodiments of the present utility model.
