Example 1
This embodiment provides an adjustable fixation system, as shown in fig. 1, comprising:
the base 100 is configured to wrap around and secure a designated body area of a user in a designated location after deformation. The matrix 100 can be semi-cylindrical or cylindrical after being deformed. Designated body areas such as the thigh, calf, etc. Designated locations such as a blood drawing console, hospital bed, etc. The base 100 includes a base member 110 and an outer guard 120. Preferably, the base member 110 includes at least a base plate 111 and a strip-shaped element, as shown in FIG. 2. Preferably, the bottom plate 111 can be a straight plate shape. Preferably, the bottom plate 111 is provided as a resilient plastic plate. The strip-shaped elements include a first strip-shaped element 112 and a second strip-shaped element 114. A plurality of first strip-shaped elements 112 are arranged on the first surface of the base plate 111 at intervals. The first strip-shaped element 112 extends between opposite sides of the base member 110. Preferably, the first strip-shaped element 112 can be a rigid foam. A second strip-shaped element 114 is disposed between adjacent first strip-shaped elements 112. A space 113 is provided between adjacent first strip-shaped elements 112, as shown in fig. 2. The empty portions 113 formed between the adjacent first strip-shaped elements 112 are adapted in size to the shape of the second strip-shaped elements 114. The empty portion 113 is filled or embedded by the second strip-shaped element 114. Preferably, the second strip-shaped element 114 is configured as a gas-permeable soft foam. Preferably, the second strip member 114 can be made of sponge. Preferably, the first strip-shaped element 112 is adhesively attached to the first face of the base member 110. Preferably, the second strip-shaped element 114 is adhesively embedded in the recess 113. Preferably, the outer guard 120 has an inner dimension that fits with the base member 110. The outer member is made of a gas impermeable material. For example, the outer member can be made of polyvinyl chloride PVC material.
According to a preferred embodiment, the outer guard 120 is sleeved on the outside of the base member 110, as shown in fig. 4-5. With the opening of the outer sheath 120 sealed, the outer sheath 120 forms the base 100 with the base member 110 received therein, as shown in fig. 5.
Preferably, the fastening system includes a gas pressure regulating assembly 200 for regulating the gas pressure inside the substrate 100, as shown in fig. 1. Preferably, the air pressure regulating assembly 200 can include a breather hose 210 and an integral pump 220 for inflating and deflating connected to the breather hose 210. The first end of the breather hose 210 communicates with the interior of the base 100. The other end of the air hose 210 is connected to an air-intake and air-exhaust integrated pump 220. Preferably, the integrated inflation and suction pump 220 can be a manual integrated inflation and suction pump. Preferably, the air pressure regulating assembly 200 includes a valve. By the gas pressure regulating assembly 200, the shape of the substrate 100 is changed due to the change of the gas pressure inside thereof by filling gas into the inside of the substrate 100 or extracting gas from the inside of the substrate 100.
Based on the degree of change in air pressure inside the matrix 100, the matrix 100 can have several shapes to adapt to the constraints of different body areas of the user.
Fig. 1 shows the form of the substrate 100 after the air pressure inside the substrate 100 is changed. After the bottom member 110 is placed into the interior space of the outer guard 120, the opening of the outer guard 120 is sealed to form the matrix 100 for restraining a designated body area of the user. When the air pressure of the inside of the base body 100 is substantially equal to the standard atmospheric pressure, the base body 100 formed of the base member 110 and the exterior member has a straight plate shape in a natural state, as shown in fig. 5. The port of the breather hose 210 remote from the base 100 is connected to a source of negative pressure that draws gas from the interior of the base 100, the opposite ends of the base member 110 begin to curl toward the first face, and because the base member 110 is inside the outer guard 120 and the dimensions of the base member 110 and the outer guard 120 are adapted, the curling of the base member 110 will cause a corresponding curling of the outer guard 120, and thus the curl formed by the base 100 will be able to constrain a specified body area of a user in a specified position.
When a negative pressure source is applied to the substrate 100, the gas inside the substrate 100 gradually decreases, that is, the gas pressure inside the substrate 100 is smaller than the standard atmospheric pressure in the initial state, and during the process of extracting the gas inside the substrate 100, the first strip-shaped elements 112 and the second strip-shaped elements 114 on the bottom plate 111 are extruded, and when the first strip-shaped elements 112 are made of hard plastics and the second strip-shaped elements 114 are made of soft foam or sponge, the first strip-shaped elements 112 are not deformed, and the second strip-shaped elements 114 are deformed due to the extrusion of the first strip-shaped elements 112 at two sides, so that the space between two adjacent first strip-shaped elements 112 is reduced. When the second strip member 114 is subjected to negative pressure, the air therein is drawn out and compressed. The reduced distance between the first strip-shaped elements 112 generates a force that deforms the base plate 111, and thus the entire matrix 100 deforms so as to wrap around the designated body area.
The greater the negative pressure applied to the substrate 100, the more pronounced the second strip-like elements 114 will contract, and the smaller the distance between the first strip-like elements 112, and thus the greater the force exerted by the base plate 111 to cause deformation itself. When the user's arm is placed on the base 100 toward the first side of the base member 110, negative pressure is applied to the base 100 through the ventilation hose 210, so that the base 100 deforms in a manner to conform to the user's hand, thereby forming a cylindrical base 100 to hold the user's arm in place. Preferably, the deformed substrate 100 can have a cross-sectional shape of a "C" shape or a semi-circular shape. Preferably, the cross-section of the deformed substrate 100 can be approximately circular in shape. According to a preferred embodiment, the base 100 is configured in a trapezoidal shape adapted to the designated body area. When deformation occurs, the base body 100 is formed in a truncated cone shape and is attached to the large arm, and according to the characteristics of a human body, the four limbs of the human body are not in a regular cylinder shape, but the diameter of the end part of the four limbs close to the head is larger than that of the end part of the four limbs close to the foot, so that the attachment degree of the truncated cone-shaped base body 100 to the large arm is higher when the large arm is wrapped.
Example 2
This embodiment is a further improvement of embodiment 1, and the repeated contents are not repeated.
A number of protrusions 112.1 are arranged on the outer wall of the outer guard 120 contacting the body part of the user. Preferably, the protrusions 112.1 are distributed on the outer wall of the outer guard 120 corresponding to the location of the first strip-shaped element 112. Preferably, several protrusions 112.1 are arranged at intervals. Preferably, the reason why the protrusions 112.1 are not provided on the outer wall of the outer guard 120 corresponding to the second strip-shaped element 114 is that: the substrate 100 is prevented from being blocked by the protrusions 112.1 on the outer wall of the outer protector 120 corresponding to the second strip-shaped element 114 when being curled, so that the substrate 100 cannot effectively fit the constrained portion of the user, and the constraining effect is further affected. The advantage of providing the protrusions 112.1 on the outer wall of the outer protector 120 corresponding to the first strip-shaped element 112 is that, on the one hand, when the base 100 is placed on a portion where the user needs to fix, such as an arm, the air is pumped out from the inside of the base 100, the base 100 curls toward the arm due to the change of the air pressure in the inside until the arm of the user is fixed in the base 100, at this time, the protrusions 112.1 in the base 100 contact with the arm, and when the pressure of the base 100 on the arm is constant after the base 100 is deformed, the friction force is increased by increasing the roughness of the contact surface between the base 100 and the arm, so that the arm of the user is not easy to slip, and the protrusions 112.1 can increase the friction of the contact surface between the base 100 and the arm; on the other hand, the protrusions 112.1 are spaced apart so that when the arm is restrained within the base 100, gas can circulate between the protrusions 112.1, ensuring ventilation of the user's arm and comfort of the user even when the arm is restrained on the base 100 for a long period of time.
Example 3
This embodiment is a further improvement of embodiment 2, and the repeated contents will not be described again.
As shown in fig. 1, the base body 100 is deformed to a state of being connected on opposite sides, where the opposite sides refer to both sides of the base body 100 transverse to the extending direction of the strip-shaped element, i.e., the cross section of the base body 100 is nearly circular. Preferably, one side of the base 100, which is not in contact with the body of the user, is provided with a fixed connection 121 to hold the base 100 in the bed.

The substrate 100 further includes a third side extending between the first end of the first side and the first end of the second side, and a fourth side extending between the second end of the first side and the second end of the second side.
Preferably, the strip-shaped elements 110 of the edges of the third and fourth sides of the base member 110 are provided with protrusions 112.1 to increase the pressure on the designated body area. Specifically, a plurality of protrusions 112.1 are provided on the first strip-shaped element 112 distributed at the edge of the base plate 111 to apply pressure to the contact site of the patient, as shown in fig. 3. As shown in fig. 1 and 5, when the base 100 is in a natural straight plate shape, the patient places the upper arm thereof at the marking position of the base 100, when the medical staff operates the air-filling and air-extracting integrated pump 220 to extract air from the base 100, the base 100 is curled, the upper arm of the patient is fixed in the curled base 100, at this time, the protrusion 112.1 contacts the vein portion of the upper arm of the patient, the protrusion 112.1 can apply local pressure to the vein, the filling degree of the vein blood vessel is improved, and further, the success rate of blood extraction is improved. Preferably, the integrated inflation and bleed air pump 220 is similar to the manual inflation and bleed air dual-purpose air pump provided by the utility model of publication number CN 202645922U. The present solution is not intended to improve the structure or control manner of the integrated pump 220, and in this solution, the integrated pump 220 can be directly implemented by using the dual-purpose pump device for manual inflation and air extraction, such as the above example.
Most children easily generate fear and excited emotion when drawing blood, struggle, do not cooperate with medical staff to draw blood, and after disinfection, arms of the children are in disorder, so that the medical staff cannot draw blood by needle insertion; or the needle has been pricked into the blood vessel, but the patient may break loose the needle, resulting in failure to draw blood, due to the patient becoming more panicked after seeing the blood. The fixing system provided in this embodiment can solve this problem, and the arm of the patient is fixed on the base 100 of the blood drawing table, so that the arm movement of the patient is limited, and the smooth blood drawing process is ensured. For patients with blood infectious diseases, such as aids patients, when blood splashes due to struggling or other actions during the blood drawing process, the infection risk of surrounding people can be increased, so that when the fixing system provided by the embodiment is used for drawing blood, the arm movement of the patients can be limited, and the accidents during the blood drawing process can be reduced.
In face of differences such as fat thin, blood viscosity, constitution of individual, medical personnel use the same dynamics to tie up tourniquet to patient's upper arm, the vascular dilatation degree is different, blood velocity is different when drawing blood, for example to the high individual of blood sugar, this individual blood vessel is thin and blood is difficult for flowing out, use treat normal individual restriction dynamics can increase the blood vessel and look for the degree of difficulty and draw blood degree of difficulty, the fixing system that this embodiment provided with the valve, pump 220 is taken out to base member 100 from the inflation of medical personnel's end through the valve for base member 100 parcel upper arm and form pressure to the upper arm. In particular, the more the extraction, the greater the structural deformation of the matrix 100, and the greater the pressure on the large arm.
